COVID-19 Pandemic
The COVID-19 pandemic, also known as the coronavirus pandemic, is an original
global pandemic of coronavirus disease 2019(COVID-19) caused by severe acute
respiratory syndrome coronavirus 2(SARS-CoV-2). The novel virus was first identified
from an outbreak in the Chinese city of Wuhan in December 2019, and attempts to
contain it there failed, allowing it to spread across the globe. The World Health
Organization (WHO) declared a public Health Emergency of International Concern on 30
January 2020 and a pandemic on 11 March 2020. As of 17 January 2022, the pandemic
had caused more than 328 million cases and 5.54 million deaths, making it one of the
deadliest in history.
COVID-19 symptoms range from undetectable to
deadly. Severe illness is more likely in elderly patients
and those with certain underlying medical conditions.
COVID-19 transmits when people breathe in air
containing by droplets and small airborne particles
containing the virus. The risk of breathing these in is
highest when people are in close proximately, but they
can be inhaled over longer distances, particularly
COVID-19 vaccines have been approved and widely
distributed in various countries since December 2020. Other recommended preventive
measures include social distancing, masking, improving ventilation and air filtration, and
quarantining those who have been exposed or are symptomatic. Treatments include
monoclonal antibodies, novel antiviral drugs, and symptom control.
The pandemic is known by several names. It’s often referred in news media as
the “coronavirus pandemic”, despite the existence of other human coronaviruses that
have caused epidemic and outbreaks (e.g., SARS).
During the initial outbreak in Wuhan, the virus and the disease were commonly referred
to as “coronavirus”. “Wuhan coronavirus”, “and the coronavirus outbreak” and the
“Wuhan coronavirus outbreak” with the disease sometimes called “Wuhan pneumonia”.

SARS-CoV-2 is a newly discovered virus that is closely related to bat
coronaviruses, pangolin coronaviruses, and SARS-Co V. The first known outbreak
started in Wuhan, Hubei, China, in November 2019. Many early cases were linked to
people who had visited the Huanan Seafood Wholesale Market there, but it is possible
that human-to-human transmission began earlier.
Official “Case” counts refer to the number of people who have been tested for
COVID-19 and whose test has been confirmed positive according to official protocols
whether or not they experienced symptomatic disease. Multiple studies claimed that total
infections are considerably greater than reported cases. The strongest risk factors for
severe illness are obesity, complications of diabetes, anxiety disorders, and the total
number of conditions.
