Coronavirus disease of 2019- A brief review of COVID-19 spread

In the later part of 2019, pneumonia of unknown origin emerged in Wuhan China. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), a member of the coronavirus family, was found the causative agent of this strange illness. The World Health Organization declared the Coronavirus Disease of 2019 (COVID-19) public health emergency of international concern. Soon, after the onset of the disease, it spread to various areas in China locally and then spread to neighboring countries through community dissemination. COVID-19 spread to six continents in just six weeks after its onset. Relaxed immigration policies and lack of expertise in epidemic control measures led to accelerated spread to the world. COVID-19 spreads through contact and droplet transmission. Adequate measures must be taken to flatten the epidemiological curve of COVID-19.
