TL;DR
The efficacy of nets treated with lambda-cyhalothrin, a pyrethroid insecticide, on malaria infection and disease was assessed for the first time at the community level in Anopheles gambiae pyrethoid resistance areas in northern Côte d'Ivoire.
Abstract
The efficacy of nets treated with lambda-cyhalothrin, a pyrethroid insecticide, on malaria infection and disease was assessed for the first time at the community level in Anopheles gambiae pyrethroid resistance areas. The study was carried out in northern Côte d'Ivoire, which is an area of kdr resistance. Four pairs of villages were selected and matched according to demographic, sociological, and ecological criteria. Among each pair, a village was randomly allocated to receive mosquito nets. More than 80% of beds were covered with nets treated with lambda-cyhalothrin and retreated after 6 months. In each village, 54 children aged 0-59 months were randomly selected and clinically monitored for 8 periods of 7 days throughout the year. Results showed that the efficacy of treated nets was maintained with a reduction of the prevalence of asymptomatic malaria infection by 12% and an estimated protective efficacy against malaria disease of 56%.

A large-scale survey of Anopheles gambiae Giles, 1902 susceptibility to DDT, dieldrin, permethrin, and deltamethrin was conducted in the Republic of Cameroon, and results likely suggested involvement of other resistance mechanism(s), such as enzyme detoxification or kdr “Leu-Ser” mutation.

Bifenthrin is likely to have a significant comparative advantage over other pyrethroids in areas with pyrethroid resistance because of its much stronger impact on the nuisance mosquito, C. quinquefasciatus, despite its slower knock-down effect and irritancy.

Of the two components of protective immunity, anti-parasite immunity and anti-toxic immunity, only the first would play a major role as age increases, and it is suggested that the initial clinical presentation of malaria attacks is not predictive of the level of protective Immunity.

In infants and older children, most of the episodes due to malaria corresponded to increased temperatures, so age dependence should be considered when designing diagnostic procedures and outcome measures for epidemiologic studies of malaria.

Development of areas for rice cultivation does not modify the annual incidence of malarial attacks despite their seasonal influence on malaria risk, however, the lower malaria morbidity rate in R1 could be explained by socio‐economic and cultural factors.

Comparative tests of pyrethroid tolerance of different strains would be valid over the 22–28°C range but, when using a discriminating dose to detect resistance, more precise temperature control is desirable.

Despite the known stimulation/repulsion effect of permethrin, use of treated bednets had no real impact on transmission and could be related to the high prevalence of the Kdr gene in the savanna form of Anopheles gambiae in the Cote d'Ivoire.
