Depends on the country and it depends on the time period your inquiring about. The top 10 of today may be different than the top 10 in history. Anyway, nobody knows this off the top of their head. That's a very heavy list for someone to look up. The National Foundation for Infectious Diseases in Washington D.C. released the following list of the top 10 infectious diseases on which it concentrated its efforts in 1999: * Antimicrobial resistance and emerging infections. * HIV and AIDS. * Vaccine-preventable diseases. * Nosocomial infections (infections acquired in a hospital setting) and opportunistic infections (infections that occur because of the altered physiological state of the patient, such as when someone is on certain antibiotics for long periods of time). * Gastrointestinal, diarrheal and foodborne diseases. * Viral hepatitis. * Tuberculosis. * Sexually transmitted diseases. * Zoonotic diseases (diseases communicable from animals to man). * Tropical infectious diseases.
