Understanding Common Viral Diseases: An Essential Overview
Viruses are primary agents behind numerous infectious diseases worldwide. While vaccines and antiviral medications help combat many viral infections, some viruses can evade immune defenses by mutating, developing resistance over time. This highlights the importance of recognizing various viral infections and their typical symptoms. Below is a detailed overview of prevalent viral diseases and the viruses responsible for them.
Encephalitis and Meningitis: These neurological conditions are caused by viruses such as JC virus, measles, arboviruses, and LCM virus, leading to symptoms like inflammation of the brain or membranes surrounding it.
Common Cold: Predominantly caused by rhinoviruses, Parainfluenza, and respiratory syncytial virus, this ailment results in symptoms such as headache, fever, fatigue, and sore throat.
Pharyngitis: Involving inflammation of the throat’s pharyngeal region, this condition manifests as a sore throat and fever. Causative viruses include Adenovirus, Epstein-Barr virus, and Cytomegalovirus.
Ocular Infections: Eye infections exhibit symptoms like pain, itching, light sensitivity, redness, and crusty discharge, often caused by adenoviruses and cytomegalovirus.
Pneumonia: A serious lung infection triggered by viruses like influenza A and B, parainfluenza, respiratory syncytial virus, adenovirus, and SARS coronavirus. Symptoms include cough with phlegm, fever, chills, breathing difficulty, and chest pain.
Viral Skin Conditions: Skin infections from viruses such as Varicella-zoster, human herpesviruses, smallpox, molluscum contagiosum, human papillomavirus, Parvovirus B19, rubella, measles, and Coxsackie A virus often display rashes, lesions, and discomfort.
