If you are traveling to any place that may have Yellow Fever than you must take preventative measures to make sure that you do not get Yellow Fever. Yellow Fever is a very horrible disease and they do not want to transmit it to other continents. Again, if you are going to any African country, get a Yellow Fever Vaccination or Yellow Fever shot.
In fact, since Yellow Fever is showing up in other countries, I would get vaccinated for Yellow Fever if I was going to travel anywhere outside North America. Yellow Fever is usually in area’s that have lots of mosquitoes, but that can be just about anywhere. I do not know if Yellow Fever is deadly, but I do know that there is an International Yellow Fever Epidemic going on right this minute. Check out where you should get a Yellow Fever shot.
