What is Influenza and How is it Spread?
Influenza is a serious respiratory illness caused by ever-changing viruses. These viruses can greatly affect your health. Knowing about them helps protect you and your family from infections.
Seasonal flu outbreaks are mainly caused by Flu A and Flu B viruses. These viruses change through antigenic drift and shift. This creates new strains each season3.
Transmission Methods
Droplets play a key role in spreading flu. Infected people release virus-filled droplets when coughing, sneezing, or talking. These droplets can travel up to 6 feet and infect others4.
- Respiratory droplets are the primary transmission method
- Viruses can spread through direct contact with contaminated surfaces
- People are most contagious in the first 3-4 days of illness
Contagious Period Insights
The flu’s contagious period is surprisingly long. You can spread the virus a day before symptoms show up. This can last until 5-7 days after you get sick4.
High-Risk Population Groups
| High-Risk Group | Vulnerability Factors |
|---|---|
| Older Adults | 65 years and older with weakened immune systems |
| Young Children | Particularly those under 2 years old |
| Pregnant Individuals | Higher risk in second and third trimesters |
| Chronic Condition Patients | Those with underlying health issues |
The CDC suggests yearly flu shots for everyone 6 months and older. Getting vaccinated can lower your risk of serious illness and hospital stays4.
Protect yourself and your community by understanding how influenza spreads and taking proactive prevention measures.
