Behavior of Coronavirus pandemic in Yemen: practical experience review.

COVID-19 is caused by a coronavirus called SARS-CoV-2, which spread, all over the world. The virus is spreading very easily and sustainably between people. Information from the ongoing pandemic disease suggests that this virus is spreading more efficiently than influenza. Older adults and people who have severe underlying medical conditions like heart or lung disease or diabetes seem to be at higher risk for developing more serious complications from COVID-19 illness. Coronavirus constantly changes through mutation. When a virus has one or more new mutation, it has called a variant of concern. There is no data from Yemen to show what type of coronavirus variant is spread in Yemen. We believe it is a unique situation where almost all people have been affected by the coronavirus. We tested the cardiac center workers and we found all of them have positive results. No severe symptoms among our staff were reported and many of them suffered from mild to moderate symptoms, which does not need admission to the hospital. Young age among this worker sample may explain the mild severity of COVID-19 infection detected; another explanation is the frequent exposure to viral infection in Yemen and the type of coronavirus variant in Yemen. We conducted this review to describe the current situation and our experience during the pandemic and further studies are needed to identify the exact variant in Yemen and the immunity response for this coronavirus variant in the Yemeni Society.
