Reported by WHO, up until December 29, 2020, there have been 79 million COVID-19 infected cases
and over 1.7 million deaths across the world posing a serious risk to public health. Those infected
with COVID-19 have symptoms varying from asymptomatic to a common cold like illness to severe
pneumonia, severe acute respiratory distress syndrome, neurologic and hepatic disease, and death.
The most common symptoms of SARS CoV-2 infected patients are fever, cough, shortness of breath,
fatigue, mental confusion, sore throat, headache. COVID-19 has an incubation period of 2-14 days.
Droplet inhalation from coughing, sneezing, or coming in close contact with COVID-19 infected
cases is found to be the most common mechanism through which people have and continue to
acquire this infection. In addition, touching the contaminated surfaces and inhaling COVID-19
particles from contaminated air can also escalate the risk of developing COVID-19 infection. During
these unprecedented times, the COVID-19 pandemic is still on the rise. As of the December 21, 2020,
there are about 77,242,026 million confirmed cases globally. Active cases as of December 21, 2020
were 21,389,271 cases worldwide of which 106,319 were in serious or critical condition. With this
manuscript we provide an overview of incidence and mortality rate of COVID-19 cases in the United
States of America (USA) and globally.
