10 Important Facts About Influenza
## Season: October to May
Although the epidemic peaks in winter, you can also catch the flu in the fall and spring. Some people start getting sick as early as October, and the virus continues to spread through May.
## Influenza can be spread through airborne droplets and touch
Flu viruses are spread through tiny droplets that form when you cough, sneeze or talk. You can also become infected by touching a surface or object that has the flu virus on it and then touching your mouth, nose, or eyes.
## Contagious even before symptoms appear
According to the Centers for Disease Control and Prevention (CDC), a person becomes contagious ===up to 24 hours before symptoms appear. The most contagious period is the first 3 to 4 days after the onset of illness. A person is safe to be around others a week after infection.
## When the feeling suddenly gets worse
The disease begins quite abruptly — one day you feel fine, but a day later you can't get out of bed because you don't feel well. Sometimes the symptoms appear the day after exposure to the virus, and other times only 4 days after infection.
The symptoms are similar to the flu. In its manifestation, the flu is generally similar to an acute respiratory infection. The symptoms include:
- Fever above 38 degrees, chills
- Dry, persistent cough
- Sore throat
- Runny or stuffy nose
- Muscle pain
- Headache, which is localized in the frontal and brow bone areas
- Fatigue, weakness
- Vomiting and diarrhea can sometimes occur (although this is more common in children)
However, contrary to widespread belief, high fever does not occur in all influenza patients.
## It is not treated with antibiotics
Antibiotics are effective only against bacteria, so they cannot treat viral diseases, including the flu. As a rule, in the first days of illness, patients are recommended to take antiviral medications and treatments to alleviate symptoms. However, against a background of a weakened immune system, a viral infection is often joined by a secondary bacterial infection. In this situation, the doctor may prescribe a course of antibiotics.
## Vaccination needs 2 weeks to start working
The seasonal flu vaccination is one of the best ways to protect yourself. However, it takes about 2 weeks to develop antibodies — which is why it's important to get vaccinated early in the season.
## You need to get the new flu shot every year
The flu has many strains and mutations, so last year's flu shot won't prevent you from getting the flu. However, the risk of falling ill remains even after timely vaccination. This can happen if contact with the virus occurred before antibodies were developed, or if the vaccine is not effective against the predominant circulating strain. On average, the vaccine reduces the risk of illness by 40-60 %.
## Vaccination may cause sickness
There is a misconception that you can get the flu after being vaccinated. This is incorrect.
Some people do experience mild flu-like symptoms after the vaccination, but they usually last only 1-2 days and are not the flu.
## Flu is life-threatening
Although most people tolerate the flu fairly easily, sometimes it causes serious complications. Those at risk include:
- People over the age of 65
- Young children, especially those under 2 years old
- Women who are pregnant or have recently given birth
- People with weakened immune systems
- People with chronic illnesses
- Native Americans (American Indians and Alaska Natives)
- People with a body mass index (BMI) over 40
However, complications can develop in anyone. The flu virus can aggravate chronic diseases such as congestive heart failure, asthma, and diabetes, can lead to heart attack and stroke, and can cause bacterial pneumonia, ear infections, and sinus infections.
