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 ]
Hepatitis B virus causes the disease hepatitis B. Hepatitis is considered to be the leading cause of liver cancer worldwide (reference). Hepatitis B virus can be found in almost every region of the world but is most prevalent in countries where the virus is endemic.
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 B infections result in 500,000 to 1,200,000 deaths per year worldwide due to the complications of chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). Hepatitis B is endemic in a number of (mainly South-East Asian) countries, making cirrhosis and hepatocellular carcinoma big killers.
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.

The following is a list of the causes of human deaths worldwide for different years arranged by their associated mortality rates. In 2002, there were about 57 million deaths. In 2005, according to the World Health Organization (WHO) using the International Classification of Diseases (ICD), about 58 million people died. [1]
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 ...
