| co-endemicity of loiasis and onchocerciasis in the south west province of cameroon: implications for mass treatment with ivermectin. | encephalopathy has been reported in cameroon in individuals heavily infected with loa loa microfilariae who were treated with ivermectin against onchocerciasis. prior to the initiation of the community-directed treatment of onchocerciasis with ivermectin (cdti) in the south west province of cameroon, an epidemiological survey of loiasis was conducted (in july 1998-july 1999) to ascertain the intensity of the disease. thick blood films were made from 1228 blood samples collected during the day. r ... | 2001 | 11816443 |
| chrysops silacea biting densities and transmission potential in an endemic area of human loiasis in south-west cameroon. | we studied the biting densities of chrysops silacea and the transmission of loiasis over 1 year in a regenerated forest in the south-west province of cameroon. a total of 3015 flies caught near a wood fire at ground level during rainy and dry seasons were identified morphologically and 1975 caught during the rainy season were dissected to determine their physiological age and infection rate. the prevalence of microfilaraemia in the human population in the study area was determined using the thic ... | 2002 | 11952954 |
| loiasis--a neglected and under-estimated affliction: endemicity, morbidity and perceptions in eastern cameroon. | loiasis is a neglected disease that may have great social and economic impact in some endemic areas. this study was designed to update the geographical distribution of loiasis and assess the frequency and perceptions of the clinical signs of the disease in the eastern province of cameroon. the investigation covered 32 villages and involved 4146 respondents. human infection with loa loa was endemic in all the study villages but the prevalence of microfilaraemia generally decreased from south to n ... | 2007 | 17316501 |
| impact of repeated large scale ivermectin treatments on the transmission of loa loa. | we have studied the impact of large-scale treatment with ivermectin on the transmission of loiasis in a forest village in south cameroon where loiasis was highly endemic, with a prevalence of 30%. after one year of parasitological and entomological surveillance without treatment, all consenting residents aged > 5 years received ivermectin 200 micrograms/kg every 3 months. for ethical reasons, treatment was interrupted after 2 years, but parasitological and entomological surveillance continued fo ... | 1998 | 9850408 |
