Corona actually has nothing to do with developed countries, developing countries or poor countries. What's different is how the government's response in dealing with corona. We can take the example of China, the Netherlands, Taiwan, the United States.
China is a total lockdown of Wuhan city because it has already fallen in corona. The Netherlands with failed herd immunity. The United States, which was initially confident of being able to conquer Corona, finally bites a finger. And finally, the successful Taiwan provided an umbrella before it rained to overcome the corona.
In Taiwan when the corona outbreak was still in Wuhan, those safe times were used to prepare for the arrival of the virus. Since SARS attacked, Taiwan already has a formal institution that monitors and handles outbreaks. So when the plague in Wuhan became uncontrollable. Taiwan has produced more masks and provided counseling, so there is no increase in the price of masks in Taiwan around USD 1.7 for 9 pieces of surgical masked. Purchase with quota & show health identity card, without a card you can not order. The maximum order is only for 14 days, order through the government website and can be taken at retail stores. Taiwan has also prepared thousands of isolation rooms in all hospitals equipped with negative pressure rooms.
