How Viruses Cause a Sore Throat
Viruses infect the mucous membranes of the throat, leading to inflammation and pain. The immune system responds by sending white blood cells to fight the infection, which causes swelling and discomfort.
Differentiating Viral from Bacterial Sore Throat
- Viral Sore Throat: Usually accompanied by cold symptoms like cough, runny nose, and hoarseness. Fever is often low-grade.
- Bacterial Sore Throat: Often caused by Streptococcus bacteria, characterized by sudden severe sore throat, high fever, and swollen lymph nodes.
Treatment and Prevention
- Treatment: Viral sore throats typically resolve on their own. Symptomatic relief includes rest, hydration, throat lozenges, and over-the-counter pain relievers.
- Prevention: Frequent hand washing, avoiding close contact with infected individuals, and covering mouth when coughing or sneezing.
