The flu, short for influenza, is a highly contagious viral infection that primarily affects the respiratory system. It is caused by influenza viruses, namely influenza A, B, and rarely C. The flu typically spreads through respiratory droplets when an infected person coughs, sneezes, or talks, but it can also spread by touching contaminated surfaces and then touching the face.
Flu causes
The flu is caused by influenza viruses, which belong to the Orthomyxoviridae family. These viruses are categorized into types A, B, and C, with influenza A and B viruses being the most common causes of seasonal flu outbreaks in humans. These influenza viruses mutate continuously, which is why flu vaccines need to be updated regularly to protect against the strains most likely to circulate during a particular flu season. Additionally, the ability of influenza viruses to undergo genetic reassortment, particularly in animals like birds and pigs where multiple influenza viruses can coexist, poses a risk for the emergence of new strains with pandemic potential.
Flu symptoms
The severity of flu symptoms can vary from mild to severe and may lead to complications, especially in vulnerable populations such as young children, elderly individuals, pregnant women, and those with weakened immune systems or underlying health conditions. Symptoms of the flu most commonly include:
- Fever or feeling feverish/chills
- Cough
- Sore throat
- Runny or stuffy nose
- Muscle or body aches
- Fatigue
- Headaches
- Vomiting and diarrhea (more common in children than adults)
Complications of the flu can include pneumonia, bronchitis, sinus infections, ear infections, and worsening of pre-existing medical conditions. Treatment for the flu typically involves rest, staying hydrated, and over-the-counter medications to alleviate symptoms. In some cases, antiviral medications may be prescribed to shorten the duration and severity of the illness, especially for those at high risk of complications.
