Hepatitis C is a viral infection that causes liver inflammation, sometimes leading to serious liver damage. The hepatitis C virus (HCV) is spread through contaminated blood, and it can be acute or chronic. Acute hepatitis C is a short-term illness that occurs within the first 6 months after someone is exposed to the virus. Chronic
Hepatitis A is a liver inflammation brought on by the hepatitis A virus (HAV). Primarily, the virus is transmitted when an uninfected (and unvaccinated) individual consumes food or water contaminated with the faeces of an infected individual. The disease is strongly linked to unclean water or food, inadequate sanitation, poor personal hygiene, and oral-anogenital contact.
Hepatitis B is a viral infection that causes liver inflammation, sometimes leading to serious liver damage. The hepatitis B virus (HBV) is transmitted through contact with the blood or other body fluids of an infected person. This can occur through sexual contact, sharing needles, or from an infected mother to her baby at birth. Symptoms
Hepatitis D, commonly referred to as “delta hepatitis,” is a viral infection of the liver (HDV). Hepatitis D is only transmitted to individuals who are simultaneously infected with the hepatitis B virus. Hepatitis D is transmitted when blood or other body fluids from an infected individual enter the body of an uninfected person. Hepatitis D
Rabies is a viral disease that causes inflammation of the brain in humans and other mammals. It is transmitted through the saliva of infected animals, usually through a bite. The virus attacks the central nervous system, leading to symptoms such as fever, muscle spasms, and hallucinations. If left untreated, rabies is almost always fatal. It

The most common cause for human disease is viral infections. Millions are still dying from viral infections, including hepatitis and human immunodeficiency viruses (HIV).
Norovirus, an RNA-based virus belonging to the family Caliciviridae is an enteric pathogen that can cause significant morbidity and mortality in health medical and communities.
Viruses that infect bacteria are known as phages or bacteriophages. Twort (19l5) described a degenerative alteration in staphylococcal colonies isolated from calf lymph that was transmissible serially via application of culture filtrates from the original growth. d’Herelle (1917) observed that the filtrates of dysentery patient faeces cultures produced transmissible lysis of a dysentery bacillus broth
What are Poxviruses? Classification of Poxviruses Based on whether they infect insect or vertebrate hosts, the family Poxviridae has been divided into two subfamilies: Chordopoxvirinae and Entomopoxvirinae. The subfamily Chordopoxvirinae encompasses viruses that infect vertebrate hosts and consists of eight genera, at least four of which cause human illness. These are the categories: The genera
