minidase inhibitors are indicated in the management of influenza.[9] In a study on possible MERS-CoV cases in Paris from 2013 to 2016, a total of 35 patients received oseltamivir (37.6%). In patients positive for influenza virus (n = 25), 52% (n = 13) received oseltamivir and it was concluded that empirical oseltamivir can be started in suspected MERS-CoV cases.[10] Many other studies also evaluated oseltamivir in MERS-CoV.[11] Oseltamivir was also used in the management of 2019-nCoV; however, definite evidence of efficacy is inconclusive because of lack of suitable control group in the studies.[12]

Protease inhibitor
There are two types of protease present in SARS-CoV, the CL-like protease and the papain-like protease, which is important for cleaving the polyproteins and releasing the nonstructural proteins (NSP1–16), whic
