According to defense scientists, protection against COVID-19 can be achieved by the naturally derived mosquito repellent given to British soldiers in April. An eight-page paper was released by the Ministry of Defense from the Porton Down-based Defense Science and Technology lab. The research has found that the virus can be killed by the spray containing Citriodiol.
