Dr Gorgas.
True
Dr.Walter Reed discovered that yellow fever is carried by mosquitos
Yes. They were both devoted to curing the plague.
Research on how to cure yellow fever was conducted by many independent doctors including my ancestor Dr. Samuel A. Mudd. Though one of the most famous doctors known for researching Yellow Fever was a Cuban doctor named Carlos Finlay. Now for your question, William Gorgas, a physician was most well known for helping fight yellow fever in Panama.
Dr. William Gorgas conducted experiments on mosquito transmission of yellow fever . He was sent to Panama in 1904 and he eradicated yellow fever from the Canal Zone and brought malaria under control, winning the battle against mosquitoes.
Malaria killed many workers on the Panama Canal. However, when Dr William Gorgas discovered that mosquitoes transmitted malaria and yellow fever, he was assigned the task of eliminating this threat for worker through fumigation of mosquito infested areas.
If you mean long ago, they didn't have antibiotics or vaccines so they had to treat the symptoms. This means to give something to bring down the fever, etc. Both malaria and yellow fever are carried by mosquitoes. That meant protecting people from them by draining standing water and using mosquito nets. Now there are vaccines for yellow fever and malaria.
