Overview

Influenza (flu)

County Health is urging everyone over the age of 6 months to get a flu shot to protect themselves and their loved ones. The best way to reduce your risk from seasonal flu and its potentially serious complications is to get vaccinated every year. Learn more about seasonal flu guidance here.

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, so it’s best not to delay getting a shot.

You can get flu shots from:

  • Your primary health care provider
  • Retail pharmacies and stores, with information and appointments available on MyTurn 

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.

Vaccine Clinics for Uninsured Individuals 

Everyone 6 months and older should be vaccinated.

Persons without insurance should contact County Health’s Health Coverage Unit at (650) 616-2002 to ask about coverage options.

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.

Overview

Lyme Disease & Tick Testing

The incidence of Lyme Disease in San Mateo County is very low.

There were 24 reported cases from 1991 to 1999, ranging from 1 to 4 cases each year. Compare this number to over 9,000 to 16,000 nationwide cases reported each year during the same time period.

The microorganism that causes Lyme Disease (Borrelia burgdorferi) is not common among ticks in San Mateo County. Young ticks, or nymphs, are more likely than adults to be infected; the nymphs often clear the infection by the time they reach adulthood.
