Flu Contagiousness: Understand How Long It Lasts
When it comes to flu contagiousness, there's no doubt that this viral infection is highly transmissible. But, do you know exactly how long the flu virus can linger and spread to others?
Whether you're already down with the flu bug or trying to avoid catching it from someone who's infected, knowing the duration of its contagiousness can help you plan and take preventive measures for yourself and your loved ones.
In this article, we'll delve into the science behind flu contagiousness and answer some of the most common questions about how long the virus can last outside and inside the body. So, buckle up and read on to learn more about protecting yourself and others from the flu.
The Science Behind Flu Contagiousness
Influenza, or the flu, is a respiratory illness caused by influenza viruses that can easily transmit from person to person. The virus has the ability to spread rapidly in crowded places such as schools, hospitals, and public transports.
When a person with the flu coughs or sneezes, tiny droplets containing the virus can land on objects like doorknobs, desks, and chairs. If another person touches those objects and then touches their eyes, mouth, or nose, they can easily contract the virus. That's why practicing good hygiene and taking preventive measures are essential to reduce the spread of the flu.
Duration of Flu Contagiousness
How Long Is the Flu Contagious?
The contagious period for the flu virus mainly starts one day before symptoms appear and can last up to seven days after the start of the illness in adults. However, children and people with weakened immune systems could remain contagious for a longer time.
It's essential to stay home and avoid contact with others during the contagious period to avoid further spread of the virus.
How Long Can Flu Virus Live Outside the Body?
The flu virus can survive outside the body for up to 24 hours on surfaces like desks, tables, and countertops. On porous surfaces like fabric and tissues, the virus can survive for up to 15 minutes. Therefore, it's essential to disinfect commonly touched surfaces regularly, especially during the peak flu season.
How Long Can Flu Virus Live Inside the Body?
The flu virus usually remains active inside the body for up to five days, depending on the severity of the illness. In severe cases, the virus could remain active for up to ten days.
Preventive Measures for Flu Contagiousness
Getting Vaccinated
The flu vaccine is the most effective preventive measure against the flu virus. It's recommended for everyone above the age of six months to get vaccinated every year before the flu season starts. The flu vaccine can reduce the risk of infection and lower the severity of the symptoms if you still contract the illness.
Practicing Good Hygiene
Washing hands frequently with soap and water for at least 20 seconds can eliminate the flu virus from your hands. Using hand sanitizers that contain at least 60% alcohol can also be an alternative when water and soap are not available. Avoid touching your eyes, nose, and mouth with unwashed hands.
Avoiding Contact with Infected People
If someone around you has the flu, avoid physical contact with them and staying in close proximity. If you develop symptoms or are diagnosed with the flu, stay home to prevent further spread of the disease.
Conclusion
In summary, the flu virus can remain contagious for up to seven days, mainly starting one day before symptoms appear. It can survive outside the body for up to 24 hours on surfaces, making disinfection necessary during peak flu seasons. Getting vaccinated, practicing good hygiene, and avoiding contact with infected people are critical measures in preventing the flu's contagiousness. Stay healthy and take preventive measures to protect yourself and your loved ones from the flu virus.
