H1N1

H1N1 (pronounced as "H-one-N-one") is a subtype of Influenza A virus that was the most common cause of human influenza (flu) in 2009. It is an orthomyxovirus that contains the glycoproteins haemagglutinin and neuraminidase.

Etymology

The name "H1N1" is derived from the virus's two main surface proteins, H1 (hemagglutinin type 1) and N1 (neuraminidase type 1). The "H" and "N" in the name refer to these proteins, which are used by scientists to classify different types of influenza viruses.

Symptoms

The symptoms of H1N1 are similar to those of other strains of influenza. They include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, fatigue, and sometimes, diarrhea and vomiting. In some cases, severe illness (pneumonia and respiratory failure) and death have occurred.

Prevention and Treatment

Prevention of H1N1 involves good personal hygiene practices, such as frequent hand washing, avoiding close contact with sick individuals, and staying home when ill. Vaccination is also an effective method of prevention. Treatment typically involves the use of antiviral medications.
