Hepatitis B virus replication. The life cycle of hepatitis B virus is complex. Hepatitis B is one of a few known pararetroviruses: non-retroviruses that still use reverse transcription in their replication process. The virus gains entry into the cell by binding to NTCP [51] on the surface and being endocytosed. Because the virus multiplies via ...
Hepatitis B: According to the World Health Organization, as of 2019 there are about 296 million people living with chronic hepatitis B, with 1.5 million new infections each year. In 2019, hepatitis B caused about 820,000 deaths, mostly from cirrhosis and hepatocellular carcinoma (primary liver cancer ). [ 23 ]
The structure of hepatitis B virus. Hepatitis B virus is a member of the Hepadnavirus family. [11] The virus particle, called Dane particle [12] (), consists of an outer lipid envelope and an icosahedral nucleocapsid core composed of protein.
This is a list of foodborne illness outbreaks by death toll, caused by infectious disease, heavy metals, chemical contamination, or from natural toxins, such as those found in poisonous mushrooms. Before modern microbiology, foodbourne illness was not understood, and, from the mid 1800s to early-mid 1900s, was perceived as ptomaine poisoning ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
Hepatitis D is a defective virus that requires hepatitis B to replicate and is only found with hepatitis B co-infection. [17] In adults, hepatitis B infection is most commonly self-limiting, with less than 5% progressing to chronic state, and 20 to 30% of those chronically infected developing cirrhosis or liver cancer. [31]
Hepatitis D is caused by the hepatitis D virus (HDV), or hepatitis delta virus; it belongs to the genus Deltavirus. HDV is similar to a satellite virus as it can only propagate in the presence of the hepatitis B virus, depending on the helper function of HBV for its replication and expression. It has no independent life cycle, but can survive ...
