The video explains that influenza, or the flu, is a viral infection that attacks the nose, throat, and lungs, causing symptoms such as fever, chills, and muscle aches. The flu virus is small and contains genetic material that allows it to make copies of itself. The virus uses spikes to infect cells and make copies of itself, leading to the spread of the infection. The methodology presented includes how the virus enters cells, replicates, and causes symptoms. To prevent the flu, getting a flu vaccine every year is recommended, as it helps stimulate an immune response that protects against new flu viruses.
### Methodology
- Influenza virus enters the body through contact with infected objects or body fluids.
- The virus uses spikes to infect cells and replicate itself.
- Antiviral drugs like oseltamivir and zanamivir can help stop the virus from spreading.
- Getting a flu vaccine exposes the body to weak forms of the virus, stimulating an immune response that protects against infection.
- Immune response involves the production of antibodies that target specific flu viruses and prevent them from infecting cells.
- Getting a flu vaccine every year is essential for continued protection against new flu viruses.
