Journal Article
Entomological aspects and the role of human behaviour in malaria transmission in a highland region of the Republic of Yemen
2016
Overview
Background
The Republic of Yemen has the highest incidence of malaria in the Arabian Peninsula, yet little is known of its vectors or transmission dynamics.
Methods
A 24-month study of the vectors and related epidemiological aspects of malaria transmission was conducted in two villages in the Taiz region in 2004–2005.
Results
Cross-sectional blood film surveys recorded an overall malaria infection rate of 15.3 % (250/1638), with highest rates exceeding 30 % in one village in May and December 2005. With one exception,
Plasmodium malariae
, all infections were
P.
falciparum.
Seven
Anopheles
species were identified among 3407 anophelines collected indoors using light traps (LT) and pyrethrum knockdown catches (PKD):
Anopheles arabiensis
(86.9 %),
An. sergentii
(9 %),
An. azaniae
,
An. dthali
,
An. pretoriensis
,
An. coustani
and
An. algeriensis
. Sequences for the standard barcode region of the mitochondrial
COI
gene confirmed the presence of two morphological forms of
An. azaniae
, the typical form and a previously unrecognized form not immediately identifiable as
An. azaniae
. ELISA detected
Plasmodium
sporozoites in 0.9 % of 2921
An. arabiensis
(23
P. falciparum
, two
P. vivax
) confirming this species as the primary malaria vector in Yemen.
Plasmodium falciparum
sporozoites were detected in
An. sergentii
(2/295) and a single female of
An. algeriensis
, incriminating both species as malaria vectors for the first time in Yemen. A vector in both wet and dry seasons,
An. arabiensis
was predominantly anthropophilic (human blood index = 0.86) with an entomological inoculation rate of 1.58 infective bites/person/year.
Anopheles sergentii
fed on cattle (67.3 %) and humans (48.3; 20.7 % mixed both species), but only 14.7 % were found in PKDs, indicating predominantly exophilic behaviour. A GIS analysis of geographic and socio-economic parameters revealed that
An. arabiensis
were significantly higher (P < 0.001) in houses with televisions, most likely due to the popular evening habit of viewing television collectively in houses with open doors and windows.
Conclusions
The predominantly indoor human biting vectors recorded in this study could be targeted effectively with LLINs, indoor residual spraying and/or insecticide-treated window/door curtains reinforced by education to instil a perception that effective and affordable malaria prevention is achievable.
