Role of Molecular Epidemiology in Infectious Disease Surveillance

Molecular epidemiology of infectious diseases: a case for increased surveillance.

Infectious diseases continue to be the leading cause of death worldwide. This is compounded by the rapid emergence both of new infections and of microbial resistance. With new drugs rarely appearing, the threats to public health are becoming increasingly grave. The major challenge for the public health community is to work out a coordinated, global and multidisciplinary approach to preventing a...

Molecular epidemiology of infectious bursal disease virus in Zambia.

Nucleotide sequences of the VP2 hypervariable region (VP2-HVR) of 10 infectious bursal disease viruses detected in indigenous and exotic chickens in Zambia from 2004 to 2005 were determined. Phylogenetic analysis showed that the viruses diverged into two genotypes and belonged to the African very virulent types (VV1 and VV2). In the phylogenetic tree, strains in one genotype clustered in a dist...

Molecular epidemiology of infectious diseases

Molecular epidemiology (ME) is a branch of epidemiology developed by merging molecular biology into epidemiological studies. In this paper, the authors try to discuss the ways that molecular epidemiology studies identify infectious diseases' causation and pathogenesis, and unravel infectious agents' sources, reservoirs, circulation pattern, transmission pattern, transmission probability, and tr...
