Infectious diseases continually evolve and mutate which raises a concern of the scientists. From common cold to AIDS and malaria, infectious diseases target people of all social classes everywhere in the world. Today, most schools and colleges of public health provide courses in infectious diseases. These programs are multidisciplinary as students learn from the interrelated fields of medical science such as immunology, virology, bacteriology, parasitology, etc.. Courses are designed not only for students who are receiving a degree in infectious diseases. Annually an increasing number of scientists, clinicians, and veterinarians need to improve their professional skills and learn more about the frequently occurring diseases.
Scientists continue to research the field of infectious diseases so that doctors can find more efficient ways to control the outbreaks. According to the recent reports, the U.S. Centers for Disease Control and Prevention achieved certain success in combating malaria abroad. The organization works with the US government and international partners to help people fight the disease which is already eradicated in the US. In 2015, the global decline in malaria deaths reached almost 50 percent among children under 5 years old. Foreign aid is essential to people who cannot afford own research to approach the infectious diseases.
Constant monitoring of the localization and spread of infectious diseases is another key goal for the researchers. Active globalization processes enhanced the transition of hosts around the world and made isolation impossible. Global trade with the countries where outbreaks of infectious diseases are registered may pose a threat to the international community.
These and many other aspects compel the attention of medical scientists. Infectious diseases provide such a great area for research that most of the studies on the topic contain certain relevant findings.
