GPT-4o mini
A viral infection is an illness caused by a virus, which is a small infectious agent that can only replicate inside the living cells of an organism. Viruses are much smaller than bacteria and cannot produce their own energy or proteins; instead, they hijack the cellular machinery of their host cells to reproduce and spread.
Viral infections can affect a wide range of organisms, including humans, animals, plants, and microorganisms. Common examples of viral infections in humans include:
- **Influenza (the flu)**
- **Common cold**
- **COVID-19** (caused by the SARS-CoV-2 virus)
- **HIV/AIDS**
- **Hepatitis**
- **Herpes simplex virus infections**
- **Measles**
Symptoms of viral infections can vary widely but often include fever, fatigue, muscle aches, cough, sore throat, and gastrointestinal distress, among others. Treatment typically focuses on relieving symptoms, as antibiotics (which treat bacterial infections) are ineffective against viruses. In some cases, antiviral medications may be prescribed to help control the infection.
Prevention of viral infections often involves vaccination, good hygiene practices, and public health measures, such as social distancing and regular handwashing.
