Causes, Symptoms and Prevention of Influenza Virus
Hi reader,
Influenza is often underestimated, even though this disease can be very dangerous, especially for vulnerable groups such as infants and young children. Although often mistaken for the common cold, influenza has its own characteristics.
Seasonal influenza, or commonly called the flu, is an acute respiratory infection caused by the influenza virus. This disease is common throughout the world and most people can recover without special treatment.
The flu virus spreads easily through coughing or sneezing. The best way to prevent it is by vaccination.
Symptoms of the flu include sudden fever, cough, sore throat, body aches, and fatigue. Treatment generally aims to relieve symptoms. Flu sufferers are advised to rest and drink plenty of fluids. Most people will recover within a week, but medical treatment may be needed for severe cases or people with high-risk factors.
Variants of Types & Causes of Influenza
There are four types of influenza viruses: A, B, C, and D. Influenza A viruses are the main cause of flu outbreaks and global pandemics. This virus often mutates, so the vaccine needs to be updated every year. Influenza B usually causes milder local outbreaks, while influenza C usually causes only mild symptoms without outbreaks.
Symptoms
Flu symptoms usually appear about two days after infection.
- Sudden fever
- Dry cough,
- Headache
- Muscle and joint pain
- Severe malaise
- Sore throat and runny nose
- The cough can be severe and last for two weeks or more.
Although most people recover without medical treatment, flu can cause serious illness or death, especially in high-risk groups. Flu can also worsen symptoms of other chronic diseases.
All age groups can be infected, but some groups are at higher risk, including pregnant women, children under 5, the elderly, people with chronic medical conditions, and those with weakened immune systems.
Treatment
Treatment for influenza in young children generally includes:
- Getting enough rest
- Monitoring and controlling fever
- Using antiviral drugs if needed
- And meeting body fluid needs
Vaccination is the best way to prevent flu. Safe and effective vaccines have been used for over 60 years. Annual vaccination is recommended because immunity from vaccines wanes over time.
WHO, through the Global Influenza Programme and the Global Influenza Surveillance and Response System (GISRS), continuously monitors influenza viruses and activity globally, recommends the composition of seasonal influenza vaccines, and supports member countries in developing prevention and control strategies.
By understanding the characteristics, symptoms, and potential dangers of influenza, we can be more vigilant and take appropriate precautions, especially to protect vulnerable groups such as infants and young children.
