Three Years Since Covid-19 Pandemic Reported

Three years have passed since early reports of a novel corona virus emerged from China, and transferred across the two spheres.

Here’s the timeline of the Coronavirus,which is an infectious disease caused by the SARS-CoV-2 virus.

On December 29, 2019, experts linkedTrusted Source four cases of pneumonia of unknown etiologyTrusted Source to the Huanan Seafood Wholesale Market in Wuhan, central China, according to WHO.

On January 7, 2020, researchers isolated the causative agent, SARS-CoV-2, and on January 10, they sequenced its genome.

By January 2, 2020, doctors had confirmed that 41 peopleTrusted Source in a Wuhan hospital with severe respiratory illness had a SARS-CoV-2 infection. Of these individuals, 27 had had exposure to the seafood market.

Many coronaviruses exist, affecting both animals and people. Most cause infections with mild to moderate symptoms in the upper respiratory tract, such as colds.

In recent years, two coronaviruses — SARS-CoV and MERS-CoVTrusted Source — have caused more severe disease. SARS-CoV, which scientists identified in November 2002, was responsible for severe acute respiratory syndrome (SARS), which emerged in Asia. 

The Centers for Disease Control and Prevention (CDC)Trusted Source note that of the 8,096 people with a known SARS infection, 774 died. There have been no reported cases since 2004.

Scientists first identified Middle East Respiratory Syndrome (MERS), the disease that MERS-CoV-2 causes, in 2012 in Saudi Arabia. The mortality rate for MERS is high — of every 10 people with the infection, three or fourTrusted Source die. 

At the beginning of 2022, many government and industry leaders are promoting policy shifts in that direction, but officials from the World Health Organization (WHO) and other health experts have warned against treating COVID-19 as an endemic disease. 

By the end of 2022, there were several hundred thousand new infections and hundreds of deaths being reported worldwide each day, and new variants of the virus continued to emerge. However, with new vaccines and treatments, the number of people dying from COVID-19 had gone down dramatically. 

The WHO didn’t announce any new strains of omicron a “variant of concern” in 2022, and by year’s end, none had produced the kind of toll the world saw with delta or the original strain of omicron.
