ABSTRACT
To investigate the consequences of maternal malaria during late pregnancy, we conducted a preliminary study in the 2 hospitals in Al Hodeidah on 276 women who had uncomplicated vaginal deliveries. Only 17 women had malaria (Plasmodium falciparum), 6 with peripheral parasitaemia and 11 with both peripheral parasitaemia and placental malaria. Coincident infection carried a 9.44 times higher risk of preterm delivery and a 12.2 times greater risk of low birth weight (< 2500 g). Anaemia was diagnosed in 46.4%, associated with malaria in 11.7% of cases. All risk factors, rural residence (OR 5.18), maternal age < 20 years (OR 4.93) and primigravidae (OR 8.29), were significantly associated with malaria infection.

To investigate the consequences of maternal malaria during late pregnancy, we conducted a preliminary study in the 2 hospitals in Al Hodeidah on 276 women who had uncomplicated vaginal deliveries. Only 17 women had malaria Plasmodium falciparum], 6 with peripheral parasitaemia and 11 with both peripheral parasitaemia and placental malaria. Coincident infection carried a 9.44 times higher risk of preterm delivery and a 12.2 times greater risk of low birth weight [< 2500 g]. Anaemia was diagnosed in 46.4%, associated with malaria in 11.7% of cases. All risk factors, rural residence [OR 5.18], maternal age < 20 years [OR 4.93] and primigravidae [OR 8.29], were significantly associated with malaria infection

The bionomics of anopheline vectors were analysed in randomly selected centres, representing fixed and spot-check stations. Three anopheline species were found. Anopheles arabiensis was the most prevalent species (84.2%) with a sporozoite rate of 0.7%, followed by A. culicifacies adenensis (14.9%) and A. rhodesiensis rupicolus (0.9%). Maximum indoor resting density was recorded during March, July and August. Positive sprayed sites for females were higher in bedrooms (40.4%) than animal sheds (26.9%). A total of 2560 anopheline larvae were collected of which 79.5% were A. arabiensis, 19.4% were A. culicifacies adenensis and 1.1% A. rhodesiensis rupicolus. A. arabiensis was assumed to be the most efficient malaria vector based on epidemiological evidence and the finding of natural sporozoite infected females.
