Over much of epidemiology early history, epidemiologists concentrated almost entirely upon human infectious diseases, and much of the epidemiological work on these diseases has focused on measuring burden, describing patterns, and attempting to understand the transmission dynamics of infectious agents.
Leukemia is the unchecked proliferation of an abnormal clone of haematopoietic cells, and leukemic cells respond poorly or inappropriately to regulatory signals, display aberrant patterns of differentiation, or even fail to differentiate. Hence, there is need for highly specific diagnostic method that can be effective.
50% of all stillbirths have been found out to be due to infections, with 98% of these happening in low- and middle-income countries. In this series of write-ups that will run for about two weeks, cursory views are taken of bacterial, viral, fungal and protozoan infections capable of causing stillbirths in pregnant women.
Zinc deficiency increases risk of infection and growth failure, and is a widespread problem for young children in countries of low and middle income. Routine zinc supplementation decreases occurrence, severity, and mortality of diarrhoea and pneumonia in children younger than 5 years living in areas where zinc deficiency is common.
