Tropical medicine is a branch of medicine integrating preclinical medicine

clinical medicine and preventive medicine

and investigating the diagnosis

treatment and prevention of diseases in tropical and subtropical regions

including tropical disease and tropical hygiene. Since climate is not the main reason why those infections remain endemic in tropical areas

there is a trend towards renaming this speciality as “Geographic Medicine” or “Third World Medicine”. The rapid development of technology provided the direction and momentum for the development of tropical medicine. At the same time

economic

environmental and social factors make the pathogen species variation

and infectious diseases become more complicated

prevention and treatment of tropical diseases have faced with new challenges in the future. From my point of view

the government should give more concerns and throw more money into the tropical medicine research and education. The new gene technology

geographic information system(GIS) and other advanced technology should be used in the diagnosis

treatment

surveillance and prevention of tropical medicine

so that people can face and control the new infectious diseases and emergent public health events. New vaccines and drugs should be developed for the prevention and treatment of new infection disease.
