Influenza

Influenza:A seasonal respiratory infection
Commonly referred to as the flu, influenza is a contagious respiratory infection brought on by influenza viruses (types A, B, C, and D). When a sick individual talks, coughs, or sneezes, it travels via respiratory droplets. Worldwide seasonal breakouts abound, most common in colder months.
Usually, the symptoms include fever, chills, coughing, sore throat, body pains, tiredness, and nasal congestion. Severe instances of influenza can cause problems including bronchitis, pneumonia, or aggravation of chronic disorders such as heart disease and asthma. Among the high-risk populations are young children, elderly people, pregnant women, and those with compromised immune systems.
Usually based on symptoms, a diagnosis is made; nonetheless, laboratory testing such as rapid influenza diagnostic tests (RIDTs) verifies the virus. If taken early, treatment consists of rest, fluids, and antiviral drugs, including oseltamivir and zanamivir, which help lower the intensity and length of the sickness.
Annual flu shots, regular hand washing, respiratory hygiene, and avoiding close contact with sick people are among the preventive steps. Since the influenza virus mutates quickly, we change vaccines annually to target prevalent strains. Public health initiatives centre around awareness campaigns and vaccination campaigns meant to lower the flu's impact and stop outbreaks.
