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 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 A, adults > 50 years old Viral Unvaccinated ≈1.8% [17]: 278 Coronavirus disease 2019 (COVID-19) Viral Unvaccinated & Treated with unspecific treatments: 0.5-2% Depends largely on the age group of the person, earlier strains of COVID-19 had higher CFR of around 2%. [53] [54] [55] Lassa fever: Viral Treated ≈1%
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.
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 ...
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 murder of five women within 10 days in Australia, allegedly by men they knew, has left Manuela Whitford feeling “numb.” 5 deaths in 10 days point to a problem Australia wants to solve Skip ...
The bills he studied were listings of numbers and causes of deaths published weekly. Graunt's analysis of causes of death is considered the beginning of the "theory of competing risks" which according to Daley and Gani [1] is "a theory that is now well established among modern epidemiologists".
