One of my dear friends just came down with influenza, and she asked me for some advice. Top of mind questions included – When can I go back to work? And when will I get better? So in a nutshell, here’s what I told her (borrowing heavily from the CDC website):
- The most common flu symptoms are: Fever or feeling feverish/chills; Cough; Sore throat; Runny or stuffy nose; Muscle or body aches; Headaches; Fatigue (feeling very tired)
- Adults shed influenza virus from the day before symptoms begin through 5—10 days after illness onset. However, the amount of virus shed, and presumably infectivity, decreases rapidly by 3—5 days after onset.
- Most experts believe that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby. Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth, eyes or possibly their nose.
- Uncomplicated influenza illness typically resolves after 3—7 days for the majority of persons, although cough and malaise can persist for >2 weeks.
- The 2011–12 U.S. seasonal influenza vaccine virus strains are identical to those contained in the 2010–11 vaccine. Annual vaccination is recommended even for those who received the vaccine for the previous season. Vaccination is the most effective prevention strategy available to reduce your risk of catching the flu.
