This study depicts that Coronavirus disease 2019 (COVID-19) is a respiratory and systemic illness that was first reported in Hubei province, China, in December 2019. Since declaring it a global pandemic by the World Health Organization on March 11, 2020, COVID-19 has quickly accelerated beyond its tipping point leading to the death of hundreds of thousands of people worldwide.
COVID-19 is caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), an RNA beta-coronavirus that likely emerged from a wet animal and fish market in the city of Wuhan. In humans, COVID-19 is a highly contagious, air-borne disease with person-to-person viral transmission occurring via respiratory droplets. Since it is a novel virus, we lack effective therapies, and hence its increased morbidity and mortality rate of about 5% according to the Johns Hopkins Coronavirus Resource Center (http://coronavirus.jhu.edu). Our understanding of the clinical spectrum of COVID-19 continues to evolve rapidly. It has been consistent across all published experiences however that older patients and those with medical comorbidities or compromised immune system are at a higher risk for worse outcomes.
