H3N3 Virus

The H3N3 virus is a subtype of the influenza A virus, which causes seasonal flu in humans. In recent years, there have been occasional reports of H3N3 infections in humans, but the virus is not typically associated with severe illness or widespread outbreaks.

In January 2022, the H3N3 virus made headlines when a person in South Carolina was diagnosed with a case of H3N3 bird flu, which is a strain of the virus that typically infects birds. The person had been exposed to sick birds and developed symptoms of fever, cough, and muscle aches.

While bird flu can be serious and even deadly in humans, the H3N3 strain is not considered to be highly pathogenic or contagious between people. Most cases of bird flu in humans are associated with exposure to infected birds or poultry, and there is no evidence of sustained human-to-human transmission of the H3N3 strain.

As with other strains of flu, the best way to prevent H3N3 infection is through vaccination. The seasonal flu vaccine typically includes protection against H3N2 and H1N1 strains, but it may not provide complete coverage against H3N3 or other less common subtypes.

In addition to vaccination, other measures to reduce the risk of flu infection include washing hands frequently, avoiding close contact with sick people, covering coughs and sneezes, and staying home when sick.

If you develop symptoms of flu, such as fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, or fatigue, it is important to seek medical care promptly. Antiviral medications may be prescribed to help shorten the duration of illness and reduce the risk of complications.

If H3N2 causes death?

Many strains of the influenza virus that can cause severe illness, including pneumonia, and in rare cases, it can lead to death. People who are at higher risk of severe illness from H3N2 and other strains of the flu include young children, older adults, pregnant women, and people with certain underlying medical conditions
