Difficulties have occurred in developing an effective anti-HIV vaccine, particularly because of variations in the antigenic viral surface protein. see ANTIGENIC VARIATION. It is thought that HIV was introduced to the human population from chimpanzees. HIV has significant potential in the field of medicine. Once stripped of its lethal elements it is probably capable of delivering genes to tissues in the brain, spinal cord, liver and heart muscle and it is unique in that it is able to insert genes into cells which are not dividing. Techniques are at present being developed, using HIV, to protect transplanted organs such as liver and heart from both infection and rejection by the immune system.

Acronym for Severe Acute Respiratory Syndrome, the epidemic lung infection that started in Guangdong province and Hong Kong in early 2003 and spread rapidly to many parts of the world. The virus is a new coronavirus and has the largest genome of any RNA virus yet found. The genome was sequenced in May 2003. SARS features fever, influenza-like symptoms, and X-ray appearances of infiltrates of variable density compatible with pneumonia. The mortality increases with age and may be as high as 50 per cent in patients over 65. Treatment is with antiviral drugs such as ribavirin in combination with antibiotics such as levofloxacin or clarithromycin. The angiotensin-converting enzyme 2 has been identified as the receptor for the coronavirus.

The ebola virus is one of the most virulent micro-organisms known, causing a variety of VIRAL HAEMORRHAGIC FEVER. Like the MARBURG virus, it belongs to the filovirus group which originates in Africa. An epidemic in West Africa in 2014–15 resulted in over 28,000 reported cases and more than 11,000 deaths. This high mortality rate was not the case in the small number of European and US health workers who contracted the disease but were treated in their own countries with intensive intravenous fluid replacement and respiratory and renal support, sometimes with the addition of investigatory use of antiviral drugs and MONOCLONAL ANTIBODY DRUGS. Strict anti-contagion measures eventually reduced spread of the epidemic since it is spread by body fluid contact from an infected person.

The COVID-19 crisis dramatically changed life in the United States. The pandemic began in late 2019, and by early 2020 had spread around the world. By October 2020, it was responsible for 1.2 million deaths globally. This makes COVID-19 deadlier than the majority of recorded wars in the modern era. The death toll in the United States is over 220,000 so far, making it one of the countries hit most severely by the disease, largely the result of poor government response and management. The early history of the disease demonstrates how the World Health Organization responded when the first reports began to appear in December of a new disease with the potential to create a pandemic. At the end of January, for only the sixth time since 1948, the WHO issued a Global Health Emergency, and by March had officially labeled COVID-19 a global pandemic But by the end of January it was already clear that the disease was spreading around the world and that containment efforts had failed.
