Breaking News: Health Advisory for Contra Costa County

Last updated: November 10, 2018, 12:38 pm

The Bay Area Air Quality Management District reports that parts of our county have unhealthy air due to smoke. Please follow the following tips to protect yourself and your loved ones. Everyone, especially children, should reduce outdoor activity. Active children and adults, and people with respiratory disease such as asthma, should avoid prolonged outdoor activity. Masks are not a substitute for staying indoors. Masks such as the N-95 are not effective for untrained users and may be dangerous for people with lung or heart conditions. N-95 masks may be helpful for people who must work outdoors if properly fitted. Employees should work with their employers for direction on when/how to use N-95 masks. Seek medical attention if you experience symptoms like repeated coughing, difficulty breathing, wheezing, chest tightness, palpitations, nausea, fatigue or lightheadedness.

Pandemic Flu

An influenza pandemic is a worldwide outbreak that occurs when a new influenza virus appears or "emerges" in the human population that may cause serious illness or death and spreads easily from person to person worldwide.

Pandemics are different from seasonal outbreaks of influenza in several ways. Whereas seasonal influenza occurs routinely worldwide each year, pandemic flu is rare. There have only been three pandemics in the past century, the most recent being the H1N1 pandemic (also known as swine flu) in 2009. A pandemic flu is caused by a new virus that few, if any, people have immunity to. It takes approximately six months to produce a vaccine against a new flu virus. During a typical flu season more than 200,000 people in the United States are hospitalized. In contrast, it's estimated that up to 9.9 million people in the U.S. could be hospitalized over the course of a severe flu pandemic.

A pandemic may last up to two years and comes and goes in waves. The flu will appear to subside until a new wave happens weeks or months later when it infects people who weren't exposed during a previous wave.
