How are viruses treated?
For most viral infections, treatments can only help with symptoms while you wait for your immune system to fight off the virus. Antibiotics do not work for viral infections. There are antiviral medicines to treat some viral infections. Vaccines can help prevent you from getting many viral diseases.
Target: Virus
Most antiviral drugs prevent infected cells from making more viruses. They work by disrupting an essential step in the viral replication cycle. A few antiviral drugs block viruses from getting into cells.
Target: The Immune System
The immune system is complicated. It’s made up of organs, cells, and molecules both large and small. Signaling molecules released from the site of infection travel in the bloodstream and throughout the body, with widespread effects. Yet scientists have learned a lot about how the immune system works.
Target: Symptoms
Another category of treatments is aimed at relieving symptoms while the immune system works on clearing the virus. This category is very broad. It includes home remedies, medical interventions that are usually delivered at hospitals, and emotional support. Some of these treatments are directed at the specific effects of a virus.
What are the effects of viruses on the respiratory system?
Viruses as invasive microorganisms may cause serious respiratory illness and in some cases life-threatening conditions, such as acute pneumonia. Although acute respiratory infection rates are not very high, this condition has been steadily increasing in children and persons over 60 years of age. The rates of hospitalization and death increase substantially in these cases. Multiple factors, such as decline in respiratory and immune function, likely contribute to increased morbidity. Natural products in all forms including pure compounds or extracts provide massive opportunities for new antiviral-lead compounds. 4,80 At the moment, only a few effective antiviral drugs are available for the treatment of viral diseases, especially in respiratory viral infections. Therefore, finding new substances with antiviral properties is a required for medical systems.
Can I use antiviral medication for myocarditis?
Since a common cause of myocarditis is viral infection, treatment with antiviral medications would seem reasonable. Different viruses, viral load, and the type of the infected cell may influence the clinical response to immunomodulatory treatment. Data regarding antiviral treatment in myocarditis are limited to murine models and a few case series in human patients, but results have been promising. In the single case series of antiviral therapy use in humans with fulminant myocarditis, ribavirin therapy did not prove effective. 128 However, most patients with acute myocarditis were diagnosed several weeks after viral infection, so it is unlikely that antiviral therapy administered once myocarditis has been confirmed would provide much benefit. In fact, some human case reports have indicated successful use of specific antiviral drugs (i.e. ganciclovir for CMV) in the early phases of disease. 129
