Hepatitis01:25

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...
Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Smallpox01:24

Smallpox

Smallpox is a severe contagious disease caused by the Variola major virus, a double-stranded DNA member of the Poxviridae family.Variola major transmission occurs primarily via inhalation of virus-laden droplets or direct contact with infectious scabs. The incubation period averages approximately seven days, although it may range from 7 to 17 days depending on the inoculum and host factors.Clinically, the prodromal phase is marked by an abrupt onset of high fever, malaise, headache, and myalgia.
Yellow Fever01:18

Yellow Fever

Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Public Health

Background:

  • Hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV) are leading causes of viral hepatitis globally.
  • These infections affect hundreds of millions worldwide, leading to significant morbidity.

Purpose of the Study:

  • To review and present current recommendations for preventing viral hepatitis.
  • To discuss vaccination and prophylaxis strategies for HAV, HBV, and HCV.

Main Methods:

  • Review of current clinical guidelines and public health recommendations.
  • Synthesis of information on vaccination schedules and post-exposure prophylaxis.

Main Results:

  • Vaccination is a primary prevention strategy for HAV and HBV.
  • Prophylaxis options exist for HAV and HBV, particularly post-exposure.
  • HCV prevention strategies focus on risk reduction and screening.

Conclusions:

  • Vaccination and prophylaxis are crucial for controlling HAV and HBV.
  • Minimizing the clinical impact of viral hepatitis requires a multi-faceted approach including vaccination and risk mitigation for HCV.
