Lesson 2b: Antivirals and antiviral strategies
There are different chemical compounds that are used as antivirals Antiviral drugs are used to treat infections caused by viruses other than HIV Antiretroviral drugs are used to treat infections…
—Principles of antiviral agents
The principles of antiviral agents guide their development, use, and mechanism of action in combating viral infections. Since viruses rely heavily on host cell machinery for replication, antiviral agents must…
—Modes of Action of Antiviral Agents
Antiviral drugs are medications specifically designed to treat viral infections by targeting the replication and spread of viruses within the body. Unlike antibiotics, which are effective against bacteria, antivirals are…
—Modulation of Host Immune Responses by Antiviral Agents
Antiviral agents not only directly inhibit viral replication but also play a crucial role in modulating host immune responses. This modulation is an essential aspect of antiviral therapy because viruses…
—Antiviral Resistance
Antiviral resistance occurs when viruses evolve mechanisms to evade the effects of antiviral drugs, rendering treatments less effective or completely ineffective. This presents a significant challenge in the treatment of…
Emerging and reemerging viral diseases of humans and animals
Emerging Viral Diseases: These are infectious diseases caused by viruses that are newly identified in a population or geographic area. They are often characterized by their sudden appearance or a…
Propagation of viruses using embryonated chicken eggs
Embryonated chicken eggs have been used for decades as a medium for virus propagation, especially for viruses that cause human and animal infections. This method is particularly famous for the…
Mechanisms of antiviral resistance: What do we need to know?
Antiviral resistance is a growing concern, especially given the rapid spread of viruses and the global impact of viral diseases. When viruses become resistant to antiviral drugs, they can continue…
Topic 12: Immune response to viral infections
The immune system is the body's natural defense against viral infections. It works by recognizing and attacking foreign invaders, such as viruses, and preventing them from causing harm. When a…
