CDC: How do I know if I have the flu?

  |  in Blog, Flu (Influenza), NewsNo Comments

Your respiratory illness might be the flu if you have fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Some people may have vomiting and diarrhea. People may be infected with the flu and have respiratory symptoms without a fever. Flu viruses usually cause the most illness during the colder months of the year. However, influenza can also occur outside of the typical flu season. In addition, other viruses can also cause respiratory illness similar to the flu. So, it is impossible to tell for sure if you have the flu based on symptoms alone. If your doctor needs to know for sure whether you have the flu, there are laboratory tests that can be done.

CDC: Why getting a Flu Vaccine is important

  |  in Blog, Flu (Influenza), NewsNo Comments

The first and most important step is to get a flu vaccination each year. If you haven’t gotten vaccinated yet, you should still try to. With very few exceptions, everyone 6 months of age and older should get an annual flu vaccine as soon as vaccines are available. Vaccination is especially important for people at high risk to decrease their likelihood of getting sick and possibly having serious illness. People at high risk of serious flu complications include young children, pregnant women, people with chronic health conditions (like asthma, diabetes or heart and lung disease), and people 65 years and older.

At this point flu vaccine may be harder to find now than it was earlier in the season. You may need to contact more than one provider (pharmacy, health department, or doctor) to find available vaccine. San Francisco residents can contact The SF Department of Public Health at: www.sfcdcp.org/flu. To find a clinic near you, visit www.flu.gov.
