Antiviral drugs are medications that help your body fight infections caused by viruses. They do not kill viruses outright but work by:

Antiviral medications are used to treat a range of conditions, including:

Influenza (Flu): Medications like oseltamivir (Tamiflu) can reduce symptoms and shorten the illness duration.
Herpes Infections: Antivirals such as acyclovir and valacyclovir treat cold sores, genital herpes, and shingles.
Hepatitis B and C: Drugs like entecavir and sofosbuvir help manage liver infections and prevent complications.
HIV/AIDS: Antiretroviral therapy (ART) involves a combination of medications to control the virus and improve the immune system.
COVID-19: Antiviral medications like remdesivir are used to manage severe cases.

Viruses can spread through:

Direct contact: Touching, kissing, or sharing personal items.
Airborne transmission: Coughing and sneezing release tiny droplets carrying the virus.
Contaminated surfaces: Touching infected surfaces and then your face.
Insect bites: Certain viruses, like Zika and dengue, are transmitted by mosquitoes.

Symptoms vary depending on the type of virus but commonly include:

While antiviral drugs are generally safe, they can have side effects, including:

Diagnosing a viral infection usually involves:

Physical Examination: Doctors check for common symptoms like fever or rashes.
Laboratory Tests: Blood tests, PCR (polymerase chain reaction), or antigen tests can confirm the virus.
Imaging: In severe cases, imaging like X-rays may help assess organ involvement.

Preventing viral infections is the best approach to staying healthy:

Vaccination: Immunization is a powerful tool against many viruses, such as flu, hepatitis, and COVID-19.
Hand Hygiene: Regular handwashing reduces the risk of transmission.
Avoiding Contact: Keep distance from infected individuals.
Healthy Lifestyle: A strong immune system helps your body fight off infections.
