Answer:
Resource to medicine and money.
Explanation:
Corona is a great example but this would apply to any pandemic. Right now in the U.S. vaccines are free to everybody allowed to get them whereas other countries have little to no vaccines and are still in the height of the pandemic.
Overall, A developing country has less access to medical care, masks/oxygen/other necessary items for medicine, news, shelter, money, and government aid.
Socially, a developed country has access to communicate and interact in a more efficient way and utilize things such as technology and safety precautions to allow working to continue. Economically, the government has more means to finance a recovery and take care of citizens where things are shut down.
Hopefully, that helped.
