This study demonstrates a reduction in the longevity of Anopheles mosquitoes post spraying as compared to pre-spraying in the intervention villages. The longevity of the vector was also significantly declined post spraying in the intervention villages as compared to unsprayed villages. The observed reduction of the expectation of life of the vector associated with IRS is promising. But further study is needed to fully understand how this will be translated to reduction of malaria transmission in the area.
Researchers challenged a leading argument that movement of Southern tenant farmers away from mosquito breeding grounds was the dominant factor in the decline of malaria in U.S. during the 1930s. Instead, targeted public health interventions and the development of local-level public health infrastructure helped eradicate the disease, according to Daniel Sledge, assistant professor of political science at UT Arlington and lead author of "Eliminating Malaria in the American South: An Analysis of the Decline of Malaria in 1930s Alabama," a paper recently published by the American Journal of Public Health.
Parasite clearance time after artemisinin-based combination therapy (ACT) may be increasing in Asian and African settings. The association between parasite clearance following ACT and transmissibility is currently unknown.
After service in the British SAS Regiment the author became a physician and then an orthopaedic surgeon.
He has held professorial positions in Canada, Vietnam and the United States, practiced and taught orthopaedic surgery in three continents and in several wars.
He has extensive experience as an expert witness in court. Somewhere along the way, time was found to operate a four hundred acre mixed farm, a one hundred seat restaurant and to obtain a licence as a flying instructor.
