Influenza (Flu)
By: Joshua Rummell Group 6
Causes of the Flu
The Influenza virus spreads mainly through droplets made when people with the virus cough or sneeze. These droplets can end up in the mouths or noses of people who are nearby or be inhaled by lungs.
Influenza Replication
The Flu can be asymptomatic and is replicated by the lysogenic cycle. However, this cycle will later trigger the Lytic cycle, where there are symptoms.
Symptoms of the Flu
Other Symptoms
Symptoms of influenza also include fever, congestion, runny nose, headaches, and fatigue.
Immune Cells Response
Helper and Killer T cells responses are well described and CD8+ immunity is important in killing infected cells. Influenza-specific cellular immunity is elicited following natural infection and several viral proteins have been identified as targets for cellular responses. Cellular responses are able to provide heterosubtypic immunity to flu viral antigens.
Treating the Flu
The flu is a minor disease that should be treated with sleep and water to let the body fight the infection on its own. Medical anti-inflammatory pain relievers may help with some of its symptoms.
