Fight the Flu
Flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat and lungs. It can cause mild to severe illness, and at times can lead to hospitalization or death.
Signs and Symptoms
Flu symptoms can come on suddenly. People who have the flu often feel some or all of the following symptoms:
- Fever or chills
- Sore throat
- Runny or stuffy nose
- Muscle or body aches
- Fatigue (tiredness)
- Some people may have vomiting and diarrhea
However, not everyone with the flu will have a fever.
Flu is spread mainly by tiny droplets made when infected persons cough, sneeze or talk. These droplets can then land in the mouths or noses of people who are nearby.
People with flu are most contagious in the first three to four days after their illness begins. However, it is possible to begin infecting others beginning one day before symptoms develop and up to five to seven days after becoming sick.
While it’s possible to still get sick with the flu after vaccination, the severity of the flu is significantly reduced and there are fewer complications than those who are unvaccinated.
Getting vaccinated also helps protect people around you, including those who are more vulnerable to serious flu illness, like babies and young children, older people and people with certain chronic health conditions.
These other tips are also recommended to protect yourself and others from the flu:
Avoid close contact with people who are sick.
Stay home from work, school and errands when you are sick.
Cover your mouth with a tissue to contain coughing and sneezing --and a mask if you're out and about for your own protection.
Wash your hands often with soap and water.
Avoid touching your eyes, nose or mouth.
Clean and disinfect commonly touched surfaces, especially when someone is ill.
