Orthomyxoviruses

Orthomyxoviruses are a group of viruses that cause influenza, or the flu. They are RNA viruses with a segmented genome, allowing genetic changes that can lead to new flu strains. These viruses infect the respiratory tract, leading to symptoms like fever, cough, sore throat, and body aches. They spread mainly through respiratory droplets when infected individuals cough or sneeze. Vaccines are developed annually to protect against the most common strains. Understanding orthomyxoviruses is important for preventing and controlling seasonal flu outbreaks and reducing associated health risks.
