Influenza (flu) is a contagious respiratory illness caused by influenza viruses. 

It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is by getting a flu vaccination each year. Every year in the United States, on average:

  • Approximately 5 percent to 20 percent of the population gets the flu;
  • More than 200,000 people are hospitalized from flu complications; and
  • About 36,000 people die from flu.

Some people, such as older people, young children, and people with certain health conditions (such as asthma, diabetes, or heart disease), are at high risk for serious flu complications.

Cost for vaccines

Students: $35 for injectable vaccine - Bring your insurance card or cost can be charged to your student account.

INFLUENZA INFORMATION

Different viruses cause the cold and flu. The two sicknesses share symptoms, but flu is more severe.

  • Cold – runny nose, mild aches, mild cough, sore throat, may have a low fever.
  • Flu – fever is usually 101 degrees or higher, more severe aches, headache, mild runny nose.
SYMPTOM COLD FLU
Fever Rare High fever
Headache Rare Prominent
General aches and pains Slight Usual, often intense
Fatigue and weakness Very mild Common. can last 2–3 weeks
Extreme exhaustion Never Early and prominent
Stuffy nose Common Sometimes
Sneezing Common Sometimes
Sore throat Common Sometimes
Chest discomfort, cough Mild Common, can get severe
Sputum Common Rare
 
  • Fever (usually high)
  • Headache

  • Extreme tiredness

  • Dry cough

  • Sore throat

  • Runny or stuffy nose

  • Muscle aches

  • Stomach symptoms (more common in children than adults)

Complications of flu can include:

  • bacterial pneumonia
  • ear infections 
  • sinus infections
  • dehydration
  • worsening of chronic medical conditions, such as congestive heart failure, asthma, or diabetes.

Flu viruses spread mainly from person to person through coughing or sneezing of people with influenza.

Sometimes people may become infected by touching something with flu viruses on it and then touching their mouth or nose.

Most healthy adults may be able to infect others beginning 1 day before symptoms develop and up to 5 days after becoming sick. 

That means that you may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick.

Take time to get a flu vaccine each year.

  • Flu vaccine protects against the three main flu strains that research indicates will cause the most illness.
  • The vaccine can make your illness milder if you become infected with a strain of virus not covered by the vaccine.

Take everyday preventive actions.

  • Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
  • Wash your hands often with soap and water or alcohol-based hand cleaners, especially after you cough or sneeze.
  • Try to avoid close contact with sick people.
  • If you get the flu, CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.

Take flu antiviral drugs if your doctor recommends them. (They are not a substitute for vaccination.)

  • Antiviral drugs are prescription medicines (pills, liquid or an inhaler) that fight against the flu by keeping flu viruses from reproducing in your body.
  • Antiviral drugs can make your illness milder and make you feel better faster. They may also prevent serious flu complications. This could be especially important for people at high risk.

HPV

Genital human papillomavirus (also called HPV) is the most common sexually transmitted infection (STI). There are more than 40 HPV types that can infect the genital areas of males and females. These HPV types can also infect the mouth and throat. Most people who become infected with HPV do not even know they have it.

  • There is no general test for men or women to check one’s overall “HPV status,” nor is there an HPV test to find HPV on the genitals or in the mouth or throat. The HPV tests on the market are only used to help screen for cervical cancer.
  • HPV is the main cause of cervical cancer in women. There are about 11,000 new cervical cancer cases each year in the United States. Cervical cancer causes about 4,000 deaths in women each year in the United States.
  • About 1 in 100 sexually active adults in the United States have genital warts at any one time.

  

Get vaccinated!

We are offering clinics for both HPV and influenza vaccines during the following dates/times:

  • October 10 | 10 a.m. - 3 p.m. | Memorial Union room 109
  • November 7 | 10 a.m. - 3 p.m. | Memorial Union room 13

Bring your student ID and insurance card.

If uninsured, you may be eligible to receive the HPV vaccine at little or no cost.

ADDITIONAL HPV INFORMATION

Most people with HPV do not develop symptoms or health problems from it.

In 90 percent of cases, the body’s immune system clears HPV naturally within two years.

But the potential for problems such as genital warts and cervical cancer is very real.

  • Genital warts usually appear as a small bump or groups of bumps in the genital area. They can be small or large, raised or flat, or shaped like a cauliflower. Health care providers can diagnose warts by looking at the genital area during an office visit. Warts can appear within weeks or months after sexual contact with an infected partner—even if the infected partner has no signs of genital warts. If left untreated, genital warts might go away, remain unchanged, or increase in size or number. They will not turn into cancer.
  • Cervical cancer usually does not have symptoms until it is quite advanced. For this reason, it is important for women to get regular screening for cervical cancer. Screening tests can find early signs of disease so that problems can be treated early, before they ever turn into cancer.
  • Other HPV-related cancers might not have signs or symptoms until they are advanced and hard to treat. These include cancers of the vulva, vagina, penis, anus, and head and neck (tongue, tonsils and throat). For signs and symptoms of these cancers, see www.cancer.gov.
  • Recurrent respiratory papillomatosis (or RRP) causes warts to grow in the throat. It can sometimes block the airway, causing a hoarse voice or troubled breathing.

HPV is passed on through genital contact, most often during vaginal and anal sex. HPV may also be passed on during oral sex and genital-to-genital contact. HPV can be passed on between straight and same-sex partners—even when the infected partner has no signs or symptoms.

A person can have HPV even if years have passed since he or she had sexual contact with an infected person. Most infected persons do not realize they are infected or that they are passing the virus on to a sex partner. It is also possible to get more than one type of HPV.

There are several ways that people can lower their chances of getting HPV:

  • Vaccines can protect males and females against some of the most common types of HPV. These vaccines are given in three shots. It is important to get all three doses to get the best protection. The vaccines are most effective when given before a person’s first sexual contact, when he or she could be exposed to HPV.
    • Girls and women: Two vaccines (Gardasil and Cervarix) are available to protect females against the types of HPV that cause most cervical cancers. Gardasil also protects against most genital warts. Both vaccines are recommended for 11- and 12-year-old girls, and for females 13 through 26 years of age, who did not get any or all of the shots when they were younger. These vaccines can also be given to girls as young as 9 years of age. It is recommended that females get the same vaccine brand for all three doses, whenever possible.
    • Boys and men: Gardasil protects males against most genital warts. This vaccine is available for boys and men, 9 through 26 years of age.
    • Gardasil is available to male and female OSU students through SHS. Call 541-737-9355 for an appointment.
  • For those who choose to be sexually active, condoms may lower the risk of HPV. To be most effective, they should be used with every sex act, from start to finish. Condoms may also lower the risk of developing HPV-related diseases, such as genital warts and cervical cancer. But HPV can infect areas that are not covered by a condom, so condoms may not fully protect against HPV.
  • People can also lower their chances of getting HPV by being in a faithful relationship with one partner; limiting their number of sex partners; and choosing a partner who has had no or few prior sex partners. But even people with only one lifetime sex partner can get HPV. That’s why the only sure way to prevent HPV is to avoid all sexual activity.

Meningococcal Disease

Meningococcal disease is a serious, potentially fatal infection that most often causes severe swelling of the tissue around the brain and spinal cord (meningitis) or a serious blood infection (meningococcemia).

Meningococcal meningitis is when the brain and spinal cord swelling is caused by the Neisseria menigitidis bacteria.

Of these bacteria, Type B causes approximately 38 percent of the cases in Oregon and is the cause of the present outbreak at OSU.

The best defense is getting vaccinated.

INFORMATION ABOUT MENINGOCOCCAL B
Vaccines Available at Student Health

In addition to the quadrivalent vaccine, there is also a new type B vaccine available that covers a strain of the bacteria that is not included in the standard 4-strain vaccine. Student Health carries Bexsero®, which is a two-dose series, one month apart, and costs approximately $235/dose. Student Health also carries Trumenba® - which is a three-dose series. 

Enrolled students may come to Student Health for the quadrivalent and type B meningococcal vaccines. Check with your insurance company to see if the cost will be covered and be sure they know that OSU is in an outbreak situation for Meningitis B. In many cases, this will require them to cover the cost of immunization at 100%. The charges can also be billed to your student account. Please direct questions about insurance coverage to your insurance plan provider.

New Vaccine Requirement

Beginning December 2017, all students age 25 and under who take classes on the Corvallis campus must be immunized with meningococcal B vaccine. New students are encouraged to satisfy all of their immunization requirements before arriving at OSU. Current students for whom this is a new requirement are encouraged to begin the vaccination series as soon as possible.

Early symptoms may be difficult to distinguish from the flu or an upper respiratory infection, or symptoms may appear suddenly and progress rapidly.

If symptoms occur, contact your health care provider as soon as possible or go to the emergency room for sudden severe symptoms.

  • Fever
  • Rash (often appears as flat, dark purple spots on arms, legs, torso)
  • Severe headache
  • Severe body aches
  • Nausea and/or vomiting
  • Feeling very drowsy or weak
  • Stiff neck
  • Confusion

The bacteria spread through the exchange of respiratory secretions during close, direct contact with an infected person.

Although "close contact" has not been clearly defined, it generally refers to individuals who have had prolonged (greater than 8 hours) contact while in close proximity (less than 3 feet) to the patient or who have been directly exposed to the patient's oral secretions during the seven days before the onset of the patient's symptoms and until 24 hours after initiation of appropriate antibiotic therapy.

Other factors that increase risk:

  • First-year college students living in residence halls
  • College students living in group settings (such as fraternities and sororities) 
  • Military recruits
  • Those who lack a spleen or have certain immune disorders.
  • Get vaccinated
  • Do not share:
    • Cups, water bottles, or eating utensils
    • Toothbrushes
    • Make-up or lip balm
    • Cigarettes, e-cigarettes, pipes, or hookah
  • Do not drink from a common punchbowl
  • Know that kissing poses a risk
  • Cover your cough (coughing and spitting can transmit the bacteria)
  • Wash hands often with soap and water, or use hand sanitizer

MRSA

MRSA is methicillin-resistant Staphylococcus aureus (also called a "staph infection").

This is a potentially dangerous type of staph bacteria that is resistant to certain antibiotics and may cause skin and other infections.

You can get MRSA through direct contact with an infected person or by sharing personal items, such as towels or razors that have touched infected skin.

Staph infections, including MRSA, occur most frequently among persons in hospitals and healthcare facilities who have weakened immune systems.

MRSA infections that occur in otherwise healthy people who have not been recently (within the past year) hospitalized or had a medical procedure (such as dialysis, surgery, catheters) are known as community-associated (CA)-MRSA infections. These infections are usually skin infections, such as abscesses, boils, and other pus-filled lesions.

MORE ABOUT MSRA

Most staph skin infections, including CA-MRSA, appear as a bump or infected area on the skin that may be:

  • Red
  • Swollen
  • Painful
  • Warm to the touch
  • Full of pus or other drainage
  • Accompanied by a fever

If you or someone in your family or living situation experiences these signs and symptoms, cover the area with a bandage and contact a healthcare professional. It is especially important to see a healthcare professional if signs and symptoms of an MRSA skin infection are accompanied by a fever.

MRSA can develop into more serious infections. It is fairly uncommon, however, that a complication of a CA-MRSA skin infection develops.

Complications are more common within the healthcare setting, where more serious infections can affect tissues inside the body, not just the skin.

Some of the most common areas affected (and the types of infections caused) include:

  • Lungs (pneumonia)
  • Bloodstream (bacteremia or septicemia)
  • Soft tissue (cellulitis)
  • Bone (osteomyelitis)
  • Inner lining of the heart (endocarditis)

Treatment for MRSA skin infections may include having a healthcare professional drain the infection and, in some cases, prescribe an antibiotic.

Do not attempt to drain the infection yourself – doing so could worsen or spread it to others.

If you are given an antibiotic, be sure to take all of the doses (even if the infection is getting better), unless your healthcare professional tells you to stop taking it.

MRSA infections can be spread through skin-to-skin contact or less frequently by touching surfaces that have MRSA on them.

MRSA is typically spread by:

  • Having direct contact with another person’s infection
  • Sharing personal items, such as towels or razors, that have touched infected skin
  • Touching surfaces or items such as used bandages contaminated with MRSA
  • Keep cuts and scrapes clean and covered
  • Practice good hygiene such as cleaning hands regularly
  • Avoid sharing personal items such as towels and razors

Norovirus

Noroviruses are a group of viruses that cause the "stomach flu," or gastroenteritis.

Viruses are very different from bacteria and parasites, some of which can cause illnesses similar to norovirus infection.

Like all viral infections, noroviruses are not affected by treatment with antibiotics, and cannot multiply outside of a person's body.

  

MORE ABOUT NOROVIRUS

Symptoms usually begin about 24 to 48 hours after ingestion of the virus, but they can appear as early as 12 hours after exposure.

Symptoms usually include:

  • nausea
  • vomiting
  • diarrhea
  • some stomach cramping

In addition, people sometimes have:

  • a low-grade fever
  • chills
  • headache
  • muscle aches
  • a general sense of tiredness

The illness often begins suddenly, and the infected person may feel very sick. In most people the symptoms last about 1 or 2 days and resolve without treatment.

Noroviruses are found in the stool or vomit of infected people.

Individuals can become infected with the virus in several ways, including:

  • Eating food or drinking liquids that are contaminated with norovirus;
  • Touching surfaces or objects contaminated with norovirus, and then placing their hands in their mouth;
  • Having direct contact with another person who is infected and showing symptoms (for example, when caring for someone with illness, or sharing foods or eating utensils with someone who is ill).

Noroviruses are very contagious and can spread easily from person to person. Both stool and vomit are infectious.

Particular care should be taken when dealing with young children in diapers who may have diarrhea.

People infected with norovirus are contagious from the moment they begin feeling ill to at least 3 days after recovery. The virus "sheds" for 72 hours after the last symptoms. Therefore, it is particularly important for people to use good handwashing and other hygienic practices after they have recently recovered from a norovirus illness.

Currently, there is no antiviral medication that works against norovirus and there is no vaccine to prevent infection. Norovirus infection cannot be treated with antibiotics because antibiotics are not effective against viruses.

If you are ill with vomiting and diarrhea, stay home and stay hydrated with plenty of fluids.

Dehydration is the most serious health effect that can result from norovirus infection. By drinking oral rehydration fluids (ORF), juice, or water, you can reduce your chance of becoming dehydrated. Sports drinks are an effective supplement for rehydration but should not be used alone since they are low in sodium and potassium.

If you can't keep down any fluids and are feeling very thirsty or lightheaded, please see your health care provider.

You can decrease your chance of contracting or spreading norovirus by following these preventive steps:

  • Stay home when you are feeling ill.
  • If you work in food service, day care or other health care facilities, stay away from work for 72 hours after your last symptoms.
  • It is best to stay away from group situations for 72 hours after your last symptoms. If you must attend class or other group gatherings, use scrupulous handwashing with soap and water and limit direct contact with others.
  • Frequently wash your hands, especially after using the toilet or changing diapers and before eating or preparing food. Do not prepare food for others while you have symptoms and for 72 hours after.
  • Handwashing with soap and water is highly recommended. There is evidence that waterless alcohol-based hand cleansers may not provide full skin disinfection against noroviruses.
  • Thoroughly wash fruits and vegetables, steam oysters before eating them and cook foods well. (Transmission can occur through eating contaminated foods).
  • Norovirus is a very robust and durable virus that is highly transmissible and can live for extended periods on environmental surfaces. Disinfect potentially contaminated surfaces thoroughly with diluted bleach: one part bleach to 9 parts water (1/3 cup bleach to 1 gallon of water.)
  • Immediately remove and wash clothing or linens that may be contaminated with virus after an episode of illness (use hot water and soap).
  • Flush or discard any vomitus and/or stool in the toilet and make sure that the surrounding area is kept clean.

Pertussis

Whooping cough (known medically as pertussis) is a highly contagious respiratory tract infection caused by a type of bacteria called Bordetella pertussis.

Although it initially resembles an ordinary cold, whooping cough may eventually turn more serious, particularly in infants. Whooping cough is most contagious before the coughing starts.

This is one of the most common vaccine-preventable childhood diseases in the United States. It's important to remember that both children and adults can get whooping cough.

  

Since the 1980s, there's been a dramatic increase in the number of cases of whooping cough, especially among teens (10 – 19 years of age) and babies less than 5 months of age. In 2005, there were more than 25,000 total reported cases.

In rare cases, whooping cough can be deadly; the disease causes an estimated 10 to 20 deaths each year in the United States.

MORE INFORMATION ON WHOOPING COUGH
  • Runny nose
  • Sneezing
  • Low grade fever
  • Cough

After 1-2 weeks, severe coughing begins.

Children with the disease cough violently and rapidly, over and over, until the air is gone from their lungs and they're forced to inhale with a loud "whooping" sound.

Adult complications

Adults are at highest risk for:

  • Bacterial pneumonia
  • Rib fracture

Other complications of adult pertussis occur rarely.

Infant complications

Infants are at highest risk for:

  • Apnea
  • Pneumonia (about 1 in 10 children)
  • Seizures (about 1 in 50)
  • Encephalopathy (about 1 in 250)

People with whooping cough usually spread the disease by coughing or sneezing while in close contact with others, who then breathe in the pertussis bacteria.

Many infants who get whooping cough are infected by older siblings or parents who might not even know they have the disease, making it important for all teens and adults to be adequately vaccinated.

The best way to prevent whooping cough is to get vaccinated.

There are vaccines for children, pre-teens, teens and adults. The childhood vaccine is called DTaP, and the vaccine for adolescents and adults is called Tdap. Both protect against tetanus, diphtheria and pertussis. A Tdap booster can be given anytime regardless of the date of one’s last tetanus booster.

Adults who want to protect themselves and any infants and children they may be in contact with should contact their healthcare provider about receiving Tdap.

Scabies

Scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis).

The microscopic scabies mite burrows into the upper layer of the skin where it lives and lays its eggs.

The most common symptoms of scabies are intense itching and a pimple-like skin rash. The scabies mite usually is spread by direct, prolonged, skin-to-skin contact with a person who has scabies.

Scabies occurs worldwide and affects people of all races and social classes. Scabies can spread rapidly under crowded conditions where close body contact is frequent.

  

MORE INFORMATION ABOUT SCABIES

When a person is infested with scabies mites the first time, symptoms usually do not appear for up to two months (2-6 weeks) after being infested.

If a person has had scabies before, symptoms appear much sooner (1-4 days) after exposure.

The most common signs and symptoms of scabies are intense itching, especially at night, and a pimple-like itchy rash.

The itching and rash each may affect much of the body or be limited to common sites such as the wrist, elbow, armpit, webbing between the fingers, nipple, penis, waist, belt-line, and buttocks. The rash also can include tiny blisters (vesicles) and scales.

Tiny burrows sometimes are seen on the skin; these are caused by the female scabies mite tunneling just beneath the surface of the skin. These burrows appear as tiny raised and crooked grayish-white or skin-colored lines on the skin surface. The mites are often few in number (only 10-15 mites per person), so these burrows may be difficult to find.

The intense itching of scabies leads to scratching that can lead to skin sores.

The sores sometimes become infected with bacteria on the skin, such as Staphylococcus aureus.

Sometimes the bacterial skin infection can lead to an inflammation of the kidneys called post-streptococcal glomerulonephritis.

Scabies usually is spread by direct, prolonged, skin-to-skin contact with a person who has scabies.

Contact generally must be prolonged; a quick handshake or hug usually will not spread scabies. Scabies in adults is frequently sexually acquired.

Scabies sometimes is spread indirectly by sharing articles such as clothing, towels, or bedding used by an infested person.

A person infested with scabies mites can transmit scabies, even if they do not have symptoms, until they are successfully treated and the mites and eggs are destroyed.

Treatment for scabies involves either oral medications or topical creams called scabicides because they kill scabies mites; some also kill eggs.

Scabicides to treat human scabies are available only with a doctor’s prescription; no “over-the-counter” (non-prescription) products have been tested and approved for humans.

Always follow the instructions provided by the doctor and pharmacist carefully, as well as those contained in the box or printed on the label.

In addition to the infested person, treatment also is recommended for household members and sexual contacts, particularly those who have had prolonged skin-to-skin contact with the infested person. All persons should be treated at the same time in order to prevent re-infestation. Retreatment may be necessary if itching continues more than 2-4 weeks after treatment or if new burrows or rash continue to appear.

In addition to medicinal treatment, bedding and clothing should be decontaminated (i.e., either machine-washed, machine-dried using the hot cycle, or dry cleaned) or removed from body contact for at least 72 hours. Fumigation of living areas is not necessary.

Scabies is prevented by avoiding direct skin-to-skin contact with an infested person or with items such as clothing or bedding used by an infested person.

Scabies treatment usually is recommended for members of the same household, particularly for those who have had prolonged skin-to-skin contact. Bedding and clothing worn or used next to the skin anytime during the 3 days before treatment should be machine washed and dried using the hot water and hot dryer cycles or be dry-cleaned.

Items that cannot be dry-cleaned or laundered can be disinfested by storing in a closed plastic bag for several days to a week. Scabies mites generally do not survive more than 2 to 3 days away from human skin. Children and adults usually can return to child care, school, or work the day after treatment.

Tuberculosis

Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis.

The bacteria usually attack the lungs, but TB bacteria can also attack other parts of the body such as the kidney, spine, and brain.

If not treated properly, TB disease can be fatal.

Not everyone infected with TB bacteria becomes sick. As a result, two TB-related conditions exist:

  • Latent TB Infection:
    TB bacteria can live in the body without making you sick. This is called latent TB infection. People with latent TB infection do not feel sick, do not have any symptoms, are not infectious and can't spread TB bacteria to others. However, if TB bacteria become active in the body and multiply, the person will go from having latent TB infection to being sick with TB disease. About 10% of those having Latent TB will go on to develop active TB disease.
     
  • Active TB Disease:
    TB bacteria become active if the immune system can't stop them from growing. When TB bacteria are active (multiplying in your body), this is called TB disease. People with TB disease are sick. They may also be able to spread the bacteria to people they spend time with every day.
  • A bad cough that lasts three weeks or longer
  • Pain in the chest
  • Coughing up blood or sputum
  • Weakness or fatigue
  • Weight loss
  • No appetite
  • Chills
  • Fever
  • Sweating at night

Once a person is infected with TB bacteria (LTBI), the chance of developing TB disease is higher if the person:

  • Has HIV infection;
  • Has been recently infected with TB bacteria (in the last 2 years);
  • Has other health problems, like diabetes, that make it hard for the body to fight bacteria;
  • Abuses alcohol or uses illegal drugs; or
  • Was not treated correctly for TB infection in the past.

Two tests may be used to detect TB bacteria in the body: a TB skin test (TST) or a TB blood test.

At Oregon State, incoming students from high-risk countries will be required to have the TB blood test. If you have a positive reaction to the test, you will be given a chest X-ray to see if you have TB disease.

Students from countries identified as high TB risk are required to complete TB screening upon arrival at Oregon State.

Students from exempt countries who have lived in a high-risk country for more than six (6) months are advised to complete a TB screening as well.

The TB screening will be available through OSU Student Health Services. In many cases, TB screening will be included in the new student orientation schedules as coordinated by INTO-OSU and OSU International Programs.

The testing must be completed within the United States, so please do not pursue advance testing in your country prior to your arrival. If you are from one of the high-risk countries, please expect to complete your TB screening upon arrival at OSU.

TB is spread through the air from one person to another.

The TB bacteria are put into the air when a person with TB disease of the lungs or throat coughs, sneezes, speaks, or sings. People nearby may breathe in these bacteria and become infected.

TB is not spread by:

  • Shaking someone’s hand
  • Sharing food or drink
  • Touching bed linens or toilet seats
  • Sharing toothbrushes
  • Kissing
  • Treatment for Latent TB Infection: If you have latent TB infection but not TB disease, your health care provider may want you be treated to keep you from developing TB disease. Treatment of latent TB infection is essential to controlling and eliminating TB in the United States. The decision about taking treatment for latent TB infection will be based on your chances of developing TB disease.
     
  • Treatment for Active TB Disease: TB disease can be treated by taking several drugs, usually for six to nine months. It is very important to finish the medicine, and take the drugs exactly as prescribed.

Travelers should avoid close contact or prolonged time with known TB patients in crowded, enclosed environments (for example, clinics, hospitals, prisons, or homeless shelters).

Travelers who will be working in clinics, hospitals, or other health care settings where TB patients are likely to be encountered should consult infection control or occupational health experts. They should ask about administrative and environmental procedures for preventing exposure to TB. Once those procedures are implemented, additional measures could include using personal respiratory protective devices.

If you think you have been exposed to someone with TB disease, contact your health care provider or local health department to see if you should be tested for TB. Be sure to tell the doctor or nurse when you spent time with someone who has TB disease.
