Infection triggers a cytokine storm, causing respiratory distress.

Bilateral alveolar damage with desquamation and fibrin deposits.

A drug that inhibits COVID-19 RdRp to stop virus replication.

Combination drug inhibiting SARS-CoV-2 protease for mild to moderate cases.

Vaccines using lipid-encapsulated modified RNA to encode spike protein.

A paramyxovirus causing rash, lifelong immunity; no antiviral treatment available.

Paramyxovirus causing swelling, no lifelong immunity; vaccine available.

Togavirus that causes congenital malformations; lifelong immunity after vaccination.

A single-stranded DNA virus that causes slapped cheek syndrome.

Vaccines for childhood viruses protect against diseases with lifelong immunity.

Disease caused by the SARS-CoV-2 virus, characterized by respiratory symptoms.

Severe acute respiratory syndrome coronavirus 2, the virus causing COVID-19.

The type of genome that SARS-CoV-2 possesses, which is necessary for its replication.

The cell surface receptor SARS-CoV-2 binds to for entry into cells.

The part of the SARS-CoV-2 spike protein that binds to ACE2, facilitating virus entry.

Ways SARS-CoV-2 spreads, including airborne, transplacental, and contact via fomites.

The ability of SARS-CoV-2 to cause disease in host organisms.

A diagnostic test, often using swabs, to detect SARS-CoV-2 infection.

A viral disease characterized by vesicular lesions on hands, feet, and mouth.

An infection causing fever, headache, and stiff neck, often due to viruses like echovirus.

A nonenveloped RNA virus, a leading cause of gastroenteritis in adults, transmitted by fecal-oral route.

An infection of the stomach and intestines leading to diarrhea and vomiting, less severe than bacterial.

The most common cause of viral gastroenteritis in children, often leading to severe diarrhea.

May stay infectious for days in water, uncooked food, and surfaces (fomites).

Diagnosed by stool PCR (Polymerase Chain Reaction) testing.

Includes vomiting, headaches, diarrhea; often afebrile (without fever).

Double-stranded RNA virus causing gastroenteritis, especially in children 6-24 months.

Diagnosed by stool antigen tests or PCR.

Includes mild to moderate fever, vomiting, and frequent watery stools; diarrhea lasts 5-7 days.

Prevented by hygiene practices and vaccination (Rotarix, RotaTeq).

Norovirus and Rotavirus primarily affect intestinal mucosal cells, causing dehydration.

A viral infection causing maculopapular rash and severe complications.

Bright red lesions with a white central dot in the mouth, indicative of measles.

A viral infection causing swelling of salivary glands, especially the parotid glands.

Inflammation of the testicles, a complication of mumps.

A viral infection known for causing congenital rubella syndrome with malformations.

A condition caused by rubella during pregnancy, leading to serious fetal defects.
