Planning your vacation to a country in Africa is an exciting experience, but it is still important to be cautious. There are many infectious diseases that flourish in the warm climate of Africa, and since some of the population is not vaccinated, these diseases can spread quickly. According to travel clinic of America, Hepatitis A is the most prevalent dangerous disease that can be stopped with vaccinations. You can avoid some disease by only drinking boiled water and wearing insect repellent, but it is also important to have the proper vaccinations. In addition to getting a booster for basic illnesses like measles, chickenpox, and the flu, make sure you have been vaccinated against these dangerous illnesses before you go to Africa.
