Probably china has already developed an anti-bodies that kill the infected cells of the virus and will cure it through medication.
We can just speculate right now, but if they really have the cure already, its there responsibility to share it to other countries, but there was no news about that until now, hopefully, they are not playing a "power game" where they want to be in the Top and want other countries to bow down first, including the US.
There are some articles that say China's lab contains different strains of viruses and there are speculations that the virus itself was created in China. Let's hope that once either of any leading countries finds the cure for the virus will not take advantage of it, hence share it with the world. The pandemic had hit each of us in all aspects: economy, business, tourism, gambling, and almost everyone is crippled. Let's hope everything will go back to normal and that we can learn all the lessons we've learned because of the lockdown and pandemic.
Keep safe everyone.
