Show Bring1 New Dangers While the average citizen usually usu-ally dees not think about thorn, almost every new scientific advance ad-vance brings with it new dangers to mankind. Luckily for us, however, how-ever, the scientists themselves watch every new menace and take steps to counteract it. Many of us have noticed the increasing in-creasing number of miles being traveled In the uir. An international interna-tional airplano schedule from tropical tro-pical America to the United States 1h being operated daily. In the-tropics the-tropics malaria and yellow fevei are transmitted by mosquitos, so it became important to ascertain whether or not infected mosquitos could travel lont distances through the air because if they could these diseases could be brought to our own community. The American Public Health Service investigated the possihle danger of the airplane as a car-ler car-ler of disease-spreading mosquitos It found that the mosquitos had no dislike for air travel for experiments exper-iments have successfully demonstrated demon-strated that they could travel more than 1200 miles, and they arrive at the end of the Journey, regardless regard-less of repeated landings, opening of doors, windows and latches during dur-ing the course of the Journey. Therefore, proper steps must be taken to prevent mosquitos carrying car-rying disease. One experiment was interesting. On Sepetember 13th, 40 mosquitos were stained and released in the . cockpit, cabins and rear compartments compart-ments of a plane at San Juan, Porto Rico. About three hours later this plane landed at Santa Domingo. Several hours later it landed in Haiti, then several hours-later hours-later in Cuba, and finally at Miami, Mi-ami, 1,250 miles from its starting point, nearly ten hours after it started. A checkup revealed that 13 of the mosquitos which started arrived in Florida. Other experiments experi-ments confirmed the possibility of transporting mosquitos by plane. |
