Middle East respiratory syndrome (MERS) is a viral respiratory infection caused by Middle East respiratory syndrome–related coronavirus (MERS-CoV). [1] Symptoms may range from none, to mild, to severe depending on age and risk level. [6] [1] Typical symptoms include fever, cough, diarrhea, and shortness of breath. [1]
The virus, which causes Middle East respiratory syndrome (MERS), is a novel coronavirus that was first identified in a patient from Jeddah, Saudi Arabia on 6 June 2012. Sporadic cases, small clusters, and large outbreaks have been reported in 24 countries, with over 2,600 cases of the virus and over 900 deaths, as of 2021.
The virus, which is carried by mosquitoes and birds, caused outbreaks of infection in North Africa and the Middle East in the 1950s and by the 1960s horses in Europe were also affected. The largest outbreak in humans occurred in 1974 in Cape Province , South Africa and 10,000 people became ill. [ 280 ]
Betacoronavirus cameli [1] (also known as Middle East respiratory syndrome–related coronavirus abbreviated as MERS-CoV), [2] or EMC/2012 (HCoV-EMC/2012), is the virus that causes Middle East respiratory syndrome (MERS). [3] [4] It is a species of coronavirus which infects humans, bats, and camels. [5]
A survey by He et al. in 2021 identified 102 mammal-affecting viruses in Chinese game animals, 65 of which were identified then for the first time. [80] They did not find any SARS-like viruses, but did find evidence for the transmission of a MERS-like virus from bats to hedgehogs. [80]
The IBV-like novel cold viruses were soon shown to be also morphologically related to the mouse hepatitis virus. [19] This new group of viruses were named coronaviruses after their distinctive morphological appearance. [7] Human coronavirus 229E and human coronavirus OC43 continued to be studied in subsequent decades.

Pigs Enteritis: Porcine coronavirus HKU15 (PorCov‑HKU15) 2014 Discovered in Hong Kong, China. [37] Humans Coronavirus disease 2019 (COVID‑19)
The sizes of viruses determined using this new microscope fitted in well with those estimated by filtration experiments. Viruses were expected to be small, but the range of sizes came as a surprise. Some were only a little smaller than the smallest known bacteria, and the smaller viruses were of similar sizes to complex organic molecules. [14]
