Source:-
It was assumed that the source of Covid-19 is bat and pangolins.pangolins(mammal) is a look like panda while climbing on tree.
Spreading of Covid-19:-
The virus is mainly spread during close contact and by small droplets produced when those infected cough, sneeze or talk.
These droplets may also be produced during breathing; however, they rapidly fall to the ground or surfaces and are not generally spread through the air over large distances. People may also become infected by touching a contaminated surface and then their face.
Efforts to prevent the virus:-
Travel restrictions, quarantines, curfews, workplace hazard controls, event postponements and cancellations, and facility closures. These include national or regional quarantines throughout the world.
various border closures or incoming passenger restrictions, screening at airports and train stations, and outgoing passenger travel bans.
Symptoms:-
Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment. Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.

Why china block US team to investigate Wuhan laboratory
Most of the countries US, Australia,UK, Canada and new Zealand also gave pressure to chinese government to give permission to their scientists to investigate in Wuhan lab. But china government don't want to give permission.
Is china government affraid by thesse government?The reason is yes, if this virus was release from bat or pangonil according to China then china must have to to give permission yo investigate on this case.so it's clear that they speard out corona virus from his laboratory. Also we know that this laboratory was not made by chinese government Us and other countries helped them to establish this laboratory.then why china doesn't give permission.
Failure of WHO:-
A lots of country had tell to WHO to find the reality of this virus such as America, Taiwan,south korea but WHO neglected all country. The director of WHO Dr.Tedros tweets that it's not a human-human transmission on 8 jan 2020. At that time 35 death case and 2-2.5 thousand confirmed cases seen in the wuhan.
After watching all cases many countries was doing lockdown to flight from China but WHO again tweets it's not necessary to remove flight from China.
My Opinion:-
If WHO alert all country to block the flight from China and also it didn't get full details from the china that it's human-human transmission.if it's get full details about Covid-19 then this situation may avoided earlier
