Guillain-Barré syndrome in Plasmodium falciparum malaria.

A patient with Plasmodium falciparum malaria developed peripheral neuropathy. Clinical, cerebro-spinal fluid examination and nerve conduction studies confirmed Guillain-Barré syndrome, not previously reported in P. falciparum malaria.

Malaria transmission at a new irrigation project in Sri Lanka: the emergence of Anopheles annularis as a major vector.

Malaria transmission was studied in a newly irrigated area of the Mahaweli project in the dry zone of Sri Lanka. Observations were performed for a three-month period following the northeast monsoon. Parasitemia in the population varied from 20.2% in February to 7% in May, and infection was due to both Plasmodium falciparum and P. vivax. Night catches of mosquitoes collected with human bait included a high proportion of Anopheles annularis. Mosquitoes containing sporozoites in the salivary glands were identified by an enzyme-linked immunosorbent assay. Anopheles culicifacies, An. annularis, and An. aconitus were all implicated as vectors in the area. The highest entomologic inoculation rate, 0.12 infected bites/hr, was observed with An. annularis and P. vivax in March. We suggest that a change in the ecosystem from dry zone forest to irrigated cultivated land is the cause of the increased prevalence of An. annularis in this area and its emergence as a major vector of malaria.

Observations on malaria patients seeking treatment in hospitals in a rural and an urban area of Sri Lanka.

Malaria in Sri Lanka is endemic in the dry zone and occurs during epidemics in the wet zone. A survey was carried out on malaria patients presenting at a hospital located in a predominantly rural area in the dry zone (Polonnaruwa) and an urban area in the wet zone (Ragama). Higher incidence of Plasmodium falciparum infections than reported nationally were observed in both locations. Of particular interest is the rapidity with which patients gained access to hospital treatment after the onset of malaria symptoms. The observed mode is 3-6 days. It is postulated that early treatment may impair the development of clinical immunity to malaria in the Sri Lankan population.
