Even though some diseases have been effectively controlled with the help of modern technologies, yet new diseases are constantly appearing and even some are resistant to drug treatments. There have been many studies on the factors, effects and treatments against infectious diseases in human as well as in animals which carried out by the scientific community around the globe but the infectious diseases continue to be increasing from time to time.

TB treatment depends on a strategy of rapid detection by sputum smear or x-ray followed by multi-drug therapy for six months which commonly called as direct observed treatment (DOTS). However, treatment for multidrug-rifampicin (the two most powerful anti-TB drugs) is longer and requires more expensive and more toxic drugs. In order to avoid TB disease from continue being a worldwide health threat, programmes like “Stop TB Strategy” by WHO recently is very important. The strategy includes the expansion and enhancement of DOTS package to ensure early case detection and diagnosis; effective drug supply and management; and to monitor and evaluate the performance and impact. Among the aims of the strategy is to address the needs poor and vulnerable populations in the world, empower people with TB and communities through partnership and educational programme as well as enable and promote research to develop new diagnostics, drugs and…show more content…
Malaria is prevalent in tropical and subtropical regions because of rainfall, consistent high temperatures and high humidity, along with stagnant waters in which mosquito larvae readily mature, providing them with the environment they need for continuous breeding. In drier areas, outbreaks of malaria have been predicted with reasonable accuracy by mapping rainfall. Malaria is more common in rural areas than in cities. The prevalence of malaria is a combination of high human population density, high anopheles mosquito population density and high rates of transmission from humans to mosquitoes and from mosquitoes to
