Infection with Echinostoma sp. in a group of travellers to Lake Tanganyika, Tanzania, in January 2017.

A small group of travellers became infected with Echinostoma sp. after ingesting raw fish which they caught in Lake Tanganyika, Tanzania, in January 2017. The infection was diagnosed by finding the characteristic eggs in stool samples collected over a 2-week period following their return to Kenya.

An outbreak of acute schistosomiasis following a church retreat to Mwanza, Tanzania, 2008.

Clinical and laboratory findings are described from 77 persons from Nairobi, Kenya, of whom 66 were diagnosed with acute Schistosoma mansoni infection following a trip to Mwanza, Tanzania. Unusual ocular symptoms were observed as a rare manifestation of acute schistosomiasis. The outbreak highlights the risk of swimming in Lake Victoria.

Polyparasitism in two rural communities with endemic Schistosoma mansoni infection in Machakos District, Kenya.

Formol-ether concentration supplemented by fresh saline smears was used to study intestinal parasites in two communities, Miu and Kitengei, in Machakos District, Kenya. These communities differed markedly in schistosome associated morbidity, in spite of similar prevalence and intensities of infection as revealed by Kato examination, Seven helminth and nine protozoan species were detected among 1011 samples examined. More than 60% of the subjects were infected with more than one parasite: one had nine.

Comparative aetiology of childhood diarrhoea in Kakamega and Kiambu Districts, Kenya.

Two hundred diarrhoea specimens collected during January to February 1988, from rural children aged 0 to 60 months in Kakamega District were examined for bacteria, parasites and rotavirus. The results were compared with a sample of 184 diarrhoea specimens matched for month of collection, taken from data collected in the same manner from children in Kiambu District. The mean ages of children in the 2 samples did not differ significantly.

Prevalence and frequency of Giardia lamblia in children aged 0 to 60 months with and without diarrhoea.

Stool specimen results from children with diarrhoea and without diarrhoea, in a rural village community in Kenya, were analysed in order to compare prevalence and age frequency distributions of Giardia between the 2 groups. There was evidence for 2 age-related prevalence peaks for Giardia in children 60 months and below. Furthermore, there appeared to be a clear Giardia-diarrhoea relationship in the age group of 19 to 24 months.

Longitudinal study of young children in Kenya: intestinal parasitic infection with special reference to Giardia lamblia, its prevalence, incidence and duration, and its association with diarrhoea and with other parasites.

84 young children from a rural community, Nderu, in Kenya, were each followed for up to 10 months, from January to November 1987. Their ages ranged from 10 to 28 months over the period of study. Stools were obtained once a week, as were reports from the mothers about presence of abdominal complaints, including diarrhoea.

A review of the epidemiology, public health importance, treatment and control of head lice.

Head lice are cosmopolitan and endemic. While they are not responsible for the spread of any disease, they are the cause of considerable social distress. They can infest anybody and do not discriminate between class or cleanliness.

Intestinal parasites in a rural community in Kenya: cross-sectional surveys with emphasis on prevalence, incidence, duration of infection, and polyparasitism.

A cross-sectional survey of intestinal parasitic infection in a rural community, Nderu, in Kiambu District, Kenya, was carried out in 1985 by examining 1129 individuals from 203 households (about 25% of the total population). This was followed by 3 more cross-sectional surveys, in January, May and October 1986, of 56 families comprising 461 individuals, who had also participated in the first survey. In the first survey, 81.

Estimation of parasitic infection dynamics when detectability is imperfect.

The simultaneous estimation of infection rate, cure rate and detectability of parasitic infections is considered. A new method for this estimation based on a simple statistical model assuming constant transition rates between parasite states is proposed. Repeated observations on the infection status of the same individuals is required for this method.

Mixed infections in childhood diarrhoea: results of a community study in Kiambu District, Kenya.

One thousand four hundred and twenty diarrhoea specimens from 846 children aged 0 to 60 months were collected and analysed for bacteria, parasites and rotavirus over a 16 month period, from June 1985 to September 1986 inclusive. The study was conducted in 4 villages situated in Kiambu District, Kenya. All the specimens were analysed for rotavirus and parasites, including Cryptosporidium.

Cryptosporidiosis and childhood diarrhoea in a rural community in Kenya.

Cryptosporidiosis has come to recent prominence as a cause of diarrhoea throughout the world in both adults and children, producing either an acute self-limiting diarrhoea or a protracted chronic diarrhoea which can be fatal in immunosuppressed patients. This study was therefore conducted to assess the prevalence of the infection among children less than five years of age in a rural community in Kiambu District, Kenya. 1420 diarrhoea specimens from children less than five years which were processed for bacteriology and parasitology were also examined for Cryptosporidium oocysts, using the modified Ziehl-Neelsen (ZN) acid-fast stain, 3.

A study of head lice among primary schoolchildren in Kenya.

Of 1270 schoolchildren (651 girls and 619 boys) from 33 urban and rural primary schools in different regions of Kenya who were examined for head lice, 17.1% were infested (8% with living lice or nits, 9.1% with dead nits).
