Over the past 10 years: As the global HIV epidemic continues, sporadic cases and outbreaks in humans of some non-human host viruses such as Ebola, Hanta, SARS and many other viruses raise concerns about future epidemics by other viruses in the new century. • The pustular lesions on the face of the mummy are very similar to those of more recent patients . Although diseases caused by viruses have been known since the 1700s and cures for many were (somewhat later) effected, the causative agent was not closely examined until 1892, when a Russian bacteriologist, D. Ivanovski, The recommended textbook is Principles of Virology. The Year 1963 Baruch Blumberg discovers hepatitis B virus (HBV). This work saved millions of lives and set the model for the production of many subsequent vaccines. Proto-oncogenes are essential for normal development but can become cancer genes when cellular regulators are damaged or modified, e.g. The Year 1949 Thomas Weller (1915–) Frederick Robbins (1916–) John Enders (1897-1985) John Enders, Thomas Weller (1915–) and Frederick Robbins (1916–) were able to grow poliovirus in vitro using human tissue culture. • Also in 1950, the World Health Organization proposed a programme to eradicate smallpox from the Americas.
