I am from india. what makes covid-19 so dangerous in some countries? many factors including climate, how soon the symptoms are diagnosed? is it like if a young person got infected and if his immunity is low, he/she could die?

Covid-19: The virus is the same everywhere. How a country responds to the pandemic determines how dangerous it will be in that country Delay in acknowledging the pandemic, continuation of activities that ignore social distancing, lack of testing, masks, ventilators in hospitals all make it worse. Climate is not yet known to be a factor ,but influenza does decrease during the warmer weather.
