Explore the most common viruses, grouped by type, with detailed insights on symptoms, transmission, risks, and prevention. Learn how these infections spread, their impact on health, and ways to stay protected.
Respiratory Viral Infections
These viruses primarily affect the respiratory system, causing symptoms like cough, fever, and difficulty breathing. They spread through airborne droplets and close contact.
- Influenza (Flu)
- COVID-19
- Common Cold (Rhinovirus, Coronavirus, RSV)
- Respiratory Syncytial Virus (RSV)
Gastrointestinal Viral Infections
These viruses cause infections in the digestive system, leading to symptoms like diarrhea, vomiting, and stomach pain. They are often spread through contaminated food or water.
Sexually Transmitted Viral Infections
These viruses spread primarily through sexual contact, affecting the reproductive system and sometimes leading to long-term health complications.
Childhood Viral Infections
These infections are common in children and often preventable through vaccination. They typically cause rashes, fever, and other systemic symptoms.
Neurological Viral Infections
These viruses can infect the nervous system, leading to conditions like meningitis, encephalitis, and paralysis. Some can be life-threatening.
Vector-Borne Viral Infections
Transmitted through insect bites (mosquitoes, ticks, etc.), these viruses can cause severe illness affecting multiple organ systems.
Chronic & Latent Viral Infections
These infections persist in the body for long periods, sometimes reactivating after being dormant. They can cause recurring symptoms or long-term health issues.
- Epstein-Barr Virus (EBV)
- Cytomegalovirus (CMV)
- Hepatitis B & C (can also be under STIs)
- Herpes Viruses (HSV, Varicella-Zoster)
Zoonotic Viral Infections (Animal-to-Human Transmission)
These viruses originate in animals and can sometimes jump to humans, leading to outbreaks or severe diseases.
Emerging & Pandemic Viral Infections
New or recently re-emerging viruses that pose a significant global health threat, often spreading rapidly across populations.
