Measles virus vs SARS-CoV-2
Reading various articles about Measles virus and Covid-19 virus i.e. SARS-CoV-2, various similarities can be seen. The key point is not only its internal structure but its outer envelope, especially the entry points that attach to human cells. I have tried to summarize the comparison here: Measles Virus Image : It bears striking similarities in envelope and shape to SARS-CoV-2 image. Further images can be seen at CDC website . Structure : It is a single-stranded, negative-sense, enveloped, non-segmented RNA virus of the genus Morbillivirus within the family Paramyxoviridae (or (-)ssRNA virus ) . Envelope : The measles virus has two envelope glycoproteins, responsible for host cell binding and invasion, on the viral surface – hemagglutinin (H) and membrane fusion protein (F). Three receptors in the human cells, for the H protein are: complement regulatory molecule CD46, the signaling lymphocyte activation molecule (SLAM or CD...
