Mono-parasite infection versus co-infections in Tanzania: the need to revise our research focus|
MAZIGO, HUMPHREY D. & AMBROSE-MAZIGO, EMMANUELA E.
Parasitic infectious agents in endemic African countries including Tanzania rarely
occurs in isolation and co-infections within a single host in populations are norms rather
than exceptions (Brooker et al., 2007; Mazigo et al., 2010a; Mboera et al., 2011). Coinfection
refers to a situation in which an individual harbours two or more infections
from different species simultaneously, where as mono-infection refers to a situation in
which an individual harbours only one infection from a single species (Brooker et al.,
2007). Several factors determines the wide geographical distributions of helminth and
protozoan parasites and they include climate, environment, socio-economic status,
human behaviour and host-specific factors such as genetics, host physiology, host
immunological status and population dynamics (Mwangi et al., 2007).
