Viruses are infectious agents that can cause severe and long-lasting effects on human health. Human immunodeficiency virus is a dangerous virus that leads to acquired immunodeficiency syndrome (AIDS). It affects the immune system and makes it difficult to fight against infections and diseases. Antiretroviral therapy (ART) is effective in treating HIV, but it cannot completely eradicate the virus. The patients need to take the medicine throughout their life.

The Hepatitis C virus (HCV) causes chronic liver infection in patients. This will lead to liver cirrhosis and cancer if it is untreated. Antiviral treatment helps to treat the hepatitis C virus. In some cases, the infection may cause long-term liver damage.

Human immunodeficiency virus (HIV)

HIV is caused by retrovirus, which is the immune system of the body. This may especially affect the CD4 cells (T cells), which are involved in protecting our body from infection.

HIV is transmitted through certain body fluids like blood, semen, vaginal fluids, and breast milk. The major cause of HIV infection is unsafe sexual intercourse, sharing of used needles, and breastfeeding of infected mother to baby. If untreated, this may lead to Acquired Immunodeficiency Syndrome (AIDS), a condition in which our immune system is more susceptible to infection.

The efficacy of HIV can be reduced all over the world by prevention measures and proper testing methods. It may lead to a treatment option.

Hepatitis C virus (HCV)

It is a blood-transmitted pathogen that mainly affects the liver. It may lead to inflammation and chronic infection of the liver.

The virus is transmitted through the sharing of needles and unscreened blood transfusion (donor with infection). Chronic HCV may lead to cause liver damage (cirrhosis and hepatocellular carcinoma). People are often unnoticed due to the silent symptoms and delayed diagnosis. Advanced research is helpful in the development of effective antiviral medication to cure HCV infection. This offers hope for the infected individual to overcome the risk of long-term liver complications. The effect of HPV can be reduced globally by proper screening, prevention methods, and easily accessible treatment options.

Conclusion

We need to understand the severity of the virus and its long-term term impact. To fight against viruses, we need to improve our research in the medical field. It is important to take proactive steps like following proper prevention measures and detecting the virus in the early stage to overcome the impact of the deadly virus worldwide.
