Influenza (Flu) is a respiratory infectious disease caused by the influenza virus, which can spread rapidly through droplets from coughing, sneezing, or close conversation with an infected person. Symptoms are usually more severe than the common cold and may lead to dangerous complications, especially in high-risk groups.
The influenza virus is divided into 4 types
- Type A is the most common and is the cause of global pandemics (Pandemic) worldwide
- Type B spreads only among humans and usually occurs seasonally, such as during the rainy or winter seasons
- Type C causes mild symptoms and is rarely found
- Type D is usually found in animals such as cattle and does not spread to humans
Who is at higher risk of getting the flu than the general population?
Groups at risk of infection and severe symptoms from influenza include
- Young children especially those under 2 years old
- Elderly people aged 65 years and older
- Pregnant women at any stage of pregnancy
- Patients with chronic diseases such as diabetes, asthma, heart disease, lung disease, or kidney disease
- People with weakened immune systems such as those infected with HIV or those undergoing chemotherapy
- Healthcare workers or those working in crowded areas such as daycare centers, schools, or public transportation systems
Flu symptoms to watch for
- Sudden high fever
- Headache and body aches
- Dry cough and sore throat
- Runny nose and nasal congestion
- Fatigue and easy exhaustion
- Loss of appetite
- Vomiting or diarrhea (commonly seen in young children)
These symptoms usually appear rapidly and are more severe than the common cold. If symptoms last more than 3 days, you should see a doctor immediately.
How to prevent the flu safely for the whole family
Preventing the flu is not difficult if everyone in the family pays attention and consistently follows preventive measures, especially during the rainy or winter seasons when the virus is more likely to spread. Starting with the annual flu vaccination is the most effective method because it helps reduce the chance of infection and clearly alleviates the severity of the disease. It is recommended to get vaccinated before the rainy season or when outbreaks begin in the community.
In addition, maintaining basic hygiene plays a very important role, such as regularly washing hands thoroughly with soap or alcohol gel, especially before eating and after coughing or sneezing. Wearing a mask when sick not only protects yourself but also reduces the chance of spreading the virus to others.
Another method not to be overlooked is avoiding crowded places during outbreaks to prevent unintentional exposure to the virus. It is also important to get enough rest, eat nutritious food, and exercise regularly to strengthen the immune system, preparing the body to fight off infections that may come unexpectedly.
When everyone in the family is disciplined in self-care and strictly follows preventive guidelines, it will effectively reduce the risk of influenza and create a protective shield for health throughout the year.
