Insights

This study found Hepatitis C virus (HCV) serotype 2 is most common in The Gambia, particularly among individuals with human immunodeficiency virus (HIV) coinfection. Routine screening for HCV in HIV patients and blood donations is recommended.

Area of Science:

  • Hepatology
  • Virology
  • Epidemiology

Background:

  • Hepatitis C virus (HCV) serotypes are crucial for understanding HCV disease, yet their epidemiology in West Africa remains understudied.
  • Coinfection with human immunodeficiency virus (HIV) significantly increases morbidity and mortality in HCV patients.

Purpose of the Study:

  • To determine the prevalence of HCV and its serotypes in HIV-infected individuals in The Gambia.
  • To investigate the association between HIV and HCV serotypes in the West African subregion.

Main Methods:

  • Screened 1500 individuals for HIV and HCV antibodies between July-December 2002.
  • Typed HCV serotypes in coinfected patients.
  • Analyzed HIV and HCV prevalence and co-infection rates.

Main Results:

  • Identified HIV prevalence at 6.7% and HCV at 1.6%, with a 0.6% co-infection rate.
  • HCV serotype 2 was most prevalent (58.1%), followed by serotype 1 (19.4%) and serotype 3 (6.5%).
  • HIV-1/HCV serotype 1 co-infection was 44.4%, and HIV-1/HCV serotype 2 co-infection was 33.3%.

Conclusions:

  • Findings suggest the West African subregion may be the origin of HCV serotype 2.
  • Highlights the need for routine HCV screening in HIV-infected individuals and blood donations in The Gambia.
  • Recommends further research to identify HCV sources in the region.

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Inhibitors of Virion Maturation and Assembly

As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
