The name "coronavirus" is derived from Latin corona, meaning "crown" or "wreath due to the characteristic appearance of virions , which have a fringe of large, bulbous surface projections creating an image reminiscent of a crown or of a solar corona. Human coronaviruses were discovered in the 1960s. The third novel coronavirus to emerge in this century is called SARS-CoV-2. It caused coronavirus disease 2019 (COVID-19), which emerged from China in December 2019 and was declared a global pandemic by the World Health Organization on March 11, 2020. The virus enters into the host body through the mouth, nose and eye. From there, the virus makes its way down into the air sacs inside the lungs, known as alveoli. Once in the alveoli, the envelope spike glycoprotein present in the virus binds to its cellular receptor, angiotensin-converting enzyme 2 (ACE2) for SARS-CoV-2. There are two commonly used nucleic acid detection technologies forSARS-CoV-2 are real-time quantitative polymerase chain reaction (RT-qPCR) and high-throughput sequencing. With no sure shot vaccine/ drug in sight till late 2021, medical practioners are using existing therapies and repurposing drugs to save lives. Prevention is the only way to stay safe and healthy. Immunity plays an important role in this disease, so it important have nutritious and healthy food to boost the immunity.
