Live Healthy: Disease & Prevention


Disease & Prevention

Vaccines (including the flu shot), STD/HIV testing, tuberculosis and hepatitis services, and diseases carried by mosquitoes and ticks.


Immunization Programs & Vaccines

Immunizations, also known as vaccines or shots, are one of the most important public health efforts to control disease spread in the world. The San Mateo County Immunization Program works with community members, parents, physicians and clinics, schools and child care centers, older adults and other health and social service organizations to ensure that immunizations are available for all. Newborns, babies, teens, pregnant women, adults and older adults need immunizations to stay healthy and protected from diseases, such as polio, whooping cough (pertussis), measles, hepatitis B and flu.


STD/HIV Clinics and Testing

The San Mateo County STD/HIV Program works to prevent STD/HIV infection and care for individuals and families affected by HIV in San Mateo County. The Program provides comprehensive, community-based prevention and testing services, STD/HIV related health care, social services, advocacy, and referrals to community agencies providing drug treatment, housing, food, dental care and other services.


What to Do About the Flu

Flu vaccines are an important step in protecting  yourself, your family, and your community from a disease that affects thousands of people in the United States every year.

Older adults, pregnant women, young adults, children, and people with other underlying health conditions are most at risk of getting the flu, but everyone six months and older should get vaccinated.

It takes two weeks after being immunized to be fully protected. The vaccine only keeps you fully protected for about one year, so it’s important to get vaccinated every year.

You can get flu shots at:

  • Your doctor’s office
  • Retail pharmacies and stores (call first to check vaccine availability)

Home-bound patients who need flu shots should call 1-800-675-8437.

Flu symptoms include fever, cough, sore throat, a runny or stuffy nose, muscle or body aches, headaches and fatigue. There are other viruses that can cause these symptoms, but a high fever and bad cough usually indicate flu.


Tuberculosis (TB)
What It Is, Where to Get Tested, and What to Do if You Have It

Tuberculosis (TB) is a serious disease that affects people all over the world. TB used to be one of the leading causes of death in the United States, but not anymore.  In most cases, tuberculosis is preventable, treatable, and curable.


Viral Hepatitis

The word “hepatitis” means inflammation of the liver. Hepatitis is most often caused by a virus.  In the US, the most common types of viral hepatitis are Hepatitis A, Hepatitis B, and Hepatitis C.

Viral hepatitis is the leading cause of liver cancer and the most common reason for liver transplantation. An estimated 4.4 million Americans are living with chronic (lifelong) hepatitis. Most do not know they are infected.
