Antiviral drugs are a class of medication specifically designed to combat viral infections. Unlike antibiotics that target bacteria, antivirals work by interfering with different stages of a virus's life cycle within the host body. This can prevent the virus from multiplying, spreading, and causing illness.

There are various antiviral drugs available in the Antivirals Drug Market each targeting specific viruses or groups of viruses. Some common examples include influenza drugs like Oseltamivir (Tamiflu), Zanamivir (Relenza), and Peramivir (Rapivab) which are effective against influenza viruses and can shorten the duration of illness.

Many Herpes simplex virus (HSV) drugs such as Acyclovir (Zovirax), and Valacyclovir (Valtrex), are easily available in the Antivirals Drug Market and used to prevent outbreaks of herpes simplex infections, including cold sores and genital herpes. There are several combinations of drugs used to treat HCV, including sofosbuvir, ledipasvir, and daclatasvir. These have significantly improved cure rates for Hepatitis E and C.Nowadays the highly active antiretroviral therapy (HAART) which has become popular in the Antivirals Drug Market is a combination of drugs that suppress HIV replication, allowing the immune system to recover and prevent AIDS development.

Within the past three decades, there has been a drastic rise in cases of viral infectious disease across the globe due to growing viral resistance combined with weakening immunity. In 2021, 36,136 individuals in the US and its dependent regions were diagnosed with HIV. HIV diagnoses in the US and its dependent regions fell by 7% overall between 2017 and 2021.
