Rapid urbanization and globalization has helped the spread of bacteria that causes infectious diseases. Microbes can evolve and create defenses against antibiotics.
A doctor in Pittsburgh conducted a longitude study of how strep throat affected students at an elementary school. The bacteria developed resistance to antibiotics, which many doctors say are overused.
The influenza virus is constantly evolving and can infect numerous species. The HA protein in the virus fuses with a cell and infects it.
Changing weather patterns and resistance to drugs has led to a spread in Malaria. The disease is transmitted by mosquitoes carrying a parasite called sporozoite. Malaria is one of the oldest recorded diseases, but there is no cure.
Biocomplexity is an integrated approach to fighting diseases, which looks at and considers all factors. Marine microbiologist Rita Caldwell developed the idea while researching cholera epidemics in Bangladesh.
