Viral infections happen when viruses invade the body's cells, taking over their functions to reproduce and spread. As viruses depend on host cells, they attach to healthy tissues, causing cell destruction and disease progression. Prompt medical care is crucial at the first signs of symptoms. These infections include a variety of categories such as respiratory illnesses, skin conditions, food-related illnesses, and sexually transmitted infections.

Key examples include:

Rhinovirus: The culprit behind the common cold, causing cough, sneezing, headache, and sore throat.

Influenza: Known as the flu, presenting with body aches, fatigue, and severe cold-like symptoms, affecting up to 20% of people each year.

Molluscum contagiosum: A skin virus mostly seen in children, marked by small, flesh-colored bumps.

Herpes simplex: Causes cold sores, mainly spread through saliva and close contact.

Varicella-zoster: Responsible for chickenpox and shingles, spreading easily via contact or contaminated items.

Hepatitis A: A foodborne virus affecting the liver, with symptoms like jaundice, nausea, and diarrhea, which can last weeks or months.

Human papillomavirus (HPV): A common STI linked to cervical cancer and genital warts; vaccines can prevent certain strains.
