Influenza The neglected killer

Influenza is a viral infection that include 4 categories of illnesses there is Influenza A, B, C, and D. Influenza A and B are the types that typically pose a threat, while C is a less threatening type and D primarily affects cattle and isn't known to inflict sickness upon humans. Influenza A viruses are classified depending upon the proteins they have on the surface of the virus. The proteins are hemagglutinin and neuraminidase.

Influenza typically attacks the elderly that have weak immune systems newborns from 6-59 months of age, pregnant women, and health care workers.

The goal of Influenza is to spread itself and pass on its genes to survive. The influenza virus attaches to the host cell and inserts the DNA from the virus to the cell so when the cell reproduces the infected DNA spreads with it.

Vaccines are available for most strains of the virus, depending on the kind of hemagglutinin and neuraminidase on the virus

Influenza is found in animals and can be transmitted to humans. It then infects your body by attacking through the respiratory system.

Symptoms of influenza include fever, sweats, muscle and joint pains, sore throat, headaches, and nausea.

Those whose chances of catching the influenza virus are higher than average include pregnant women, the elderly, children, health care workers, and people with preexisting chronic medical conditions. The lethality increases especially amongst children, the elderly, and those with preexisting medical conditions.

Influenza accounts for about 226,000 hospitalizations each year nationwide and between 3,000 and 49,000 deaths, all depending on how severe the influenza strain is. Flu shots are the best defense against influenza.
