Confirmed case:

Probable case recognized fantastic in an mainly outfitted excessive biosafety level laboratory and thru either of these techniques; Viral RNA detection (RT-PCR) in blood or tissues and virus isolation at some point of 1st week of illness. Confirmation of presence of IgM / IgG antibodies in serum by using ELISA from day 7 of illness.
