China identifies new coronavirus as cause of the outbreak.
China reports first death linked to the new coronavirus, 2019-nCoV. The patient was 61 year old male.
China shares the genetic sequence of the novel coronavirus, helping countries in testing and tracing any potentially infected people.

WHO Director-General TedrosAdhanomGhebreyesus declares the 2019-nCoV outbreak a public health emergency of international concern, noting the potential spread of the virus to countries with weak health systems.
India reported its first confirmed case of 2019-nCoV.
China launches a clinical trial of Gilead’s antiviral drug remdesivir, previously tested in patients with Ebola, against the 2019-nCoV, just as China’s Huoshenshan Hospital in Wuhan starts operations. The hospital was built in 10 days and is dedicated to treating 2019-nCoV patients.
The death toll of victims of the 2019-nCoV is now over 800, surpassing the death toll of the SARS epidemic in 2002 and 2003, which killed 773 people.
WHO assigns the novel coronavirus its official name: COVID-19.
China publishes a paper with detailed information on more than 44,000 confirmed cases of COVID-19.The data shows that more than 80% of patients have mild disease; about 14% of cases lead to severe diseases, including pneumonia; about 5% of cases lead to critical diseases including respiratory failure, septic shock and multiorgan failure; and about 2% of reported cases lead to death.
The number of COVID-19 cases surpasses 100,000.
WHO Director-General TedrosAdhanomGhebreyesus declares the global COVID-19 outbreak a pandemic.
“Europe has now become the epicenter of the pandemic, with more reported cases and deaths than the rest of the world combined, apart from China,” saysWHO Director-General TedrosAdhanomGhebreyesu.
Global cases of COVID-19 surpass 300,000. It took over three months to reach the first 100,000 confirmed cases, 12 days to reach 200,000 and three days to reach 300,000.
U.K. Prime Minister Boris Johnson tests positive for COVID-19.
In a scientific brief, WHO reiterates respiratory droplets and indirect contact with surfaces or objects used by an infected person are still the main routes of transmission for SARS-CoV-2.
Cases of COVID-19 surpass 1 million.
China lifts its lockdown on Wuhan, the city where the COVID-19 outbreak began.
The number of COVID-19 cases surpasses 2 million.
How coronavirus gets inside the cell of the host cell
Researchers have found that the SARS-CoV-2 spike was 10 to 20 times more likely to bind ACE2 on human cells than the spike from the SARS virus from 2002. This may enable SARS-CoV-2 to spread more easily from person to person than the earlier virus.
Even though there is similarity in the protein structure of the spikes of 2002 SARS and SARS-CoV-2, the antibodies that were effective against 2002 SARS haven’t shown any result for SARS-CoV-2. As such, researchers are studying this virus closely to find a cure.
