RESUMO

Objective: In this impact survey on the preventive chemotherapy against lymphatic filariasis, the national neglected tropical diseases programme team conducted a Transmission Assessment Survey in the health districts of Leo, Sapouy, Boromo and Dedougou. The purpose of this study was to assess lymphatic filariasis transmission in these four districts (included in two evaluation units (EU): Boucle du Mouhoun 3 and Centre-Ouest 2 after more than ten to thirteen years of mass drug treatment. Methodology: The study was a cross sectional survey which targeted the school aged children based on the cluster survey method conducted at community level. Results: Among the 1649 school aged children covered by the survey in the Centre Ouest EU, four were found positive at the Filariasis Test Strip (FTS), i.e. the proportion of children with circulating filarial antigens (i.e. with live adult stages of W. bancrofti ) was 0.24%. In the BMH3 EU, none of the 1716 children tested was FTS-positive. Conclusion: From the findings, we can infer that filariasis transmission has been interrupted in these districts and that mass treatment with albendazole and ivermectin can be stopped.

RESUMO

The implementation of mass drug administration (MDA) campaigns of albendazole (400 mg) and ivermectin (150-200 µm/kg) since 2001 has helped to change the epidemiological profile of lymphatic filariasis (LF) in many health districts in Burkina Faso. From 2002 to 2016, 14 rounds of MDA have taken place in the Central East zone, with therapeutic coverage exceeding 65%. The objective of the current study was to evaluate the impact of MDA in the fight against LF at 12 sentinel and spot-check sites. This descriptive cross-sectional study surveyed subjects aged 5 years and older between April and July 2017 at these 12 sites. The blood smear performed on nocturnal samples was used to diagnose Wuchereria bancrofti infection. The study included 4364 subjects. Their mean age was 20.55 years with a standard deviation of 14.22 and a range of 5 to 96 years. The overall prevalence of microfilaremia was 0.62% (27/4364), with rates exceeding 1% at three (3) sites. The average microfilaremia density was 106 µf/mL. The overall prevalence of morbidity was low (0.91%), predominantly lymphedema (0.60%). The MDA strategy has helped to reduce the prevalence of LF significantly in Burkina Faso, but some outbreaks still have microfilarial prevalence greater than 1%. Continuation of the additional 2-year strategy with improved adherence to treatment and vector control would help break LF transmission.

RESUMO

To determine the current status of schistosomiasis and soil-transmitted helminth (STH) infections among schoolchildren after 10 years of mass treatment with praziquantel. Parasitological surveys were conducted in 2013 in 22 primary schools located in 11 regions of Burkina Faso. Urine filtration methods and Kato-Katz techniques for stool were used to detect the eggs of Schistosoma hæmatobium, Schistosoma mansoni, and STH. 3514 schoolchildren aged from 7 to 11 (1.415 ± 9) years participated in the study. The prevalence of S. hæmatobium was 8.1% and of S. mansoni, 1.2%. The prevalence of intestinal schistosomiasis ranged from 0.6% to 26.2% and that of urinary schistosomiasis from 0.6% to 56.2%. The prevalence of hookworms was 1.1%, Ascaris lumbricoides 0.1%, and Trichuris trichiura 0.06%. The arithmetic mean of S. hæmatobium and S. mansoni were respectively 6 eggs/10 mL and 1.07 epg (eggs per gram). The arithmetic means of eggs were 0.07 epg, 0.03 epg, and 1.89 epg respectively for A. lumbricoides, T. trichiura, and Ankylostoma spp. This study shows the current situation for schistosomiasis and STH infections in different regions of Burkina Faso. Elimination of this parasitic disease requires the inclusion of other control methods, in addition to mass treatment.

RESUMO

Even though the expanded programme for immunization (EPI) coverage at national level is high in Burkina (95% of fully vaccinated children), mothers of children following EPI in Health Centres (HC) would benefit from being reminded of EPI sessions by sending SMS (short message service) to their own mobile phone, or through mobile phone of a family member living in the same compound. SMS could be sent through Computerized Immunization Registers (CIR), hosted by HC computers. 210 mothers of children aged 0 to 5 years were chosen at random and questioned if they owned a mobile phone, if they could read a SMS, or, if not, what language they would understand if a voice SMS was sent. They were also asked if a family member could receive, read and transmit the message, if mothers did not own a mobile phone. They were also asked if they are willing to give their telephone number to HC. 94% of mothers could be reached through written or voice SMS, sent to their own or family member's mobile phone. 100% of mothers would be willing to give their telephone number to their HC to improve their ability to come at the right time for vaccination sessions. SMS reminders, delivered through CIR, should improve EPI attendance and management of sessions in HC, especially in epidemic context.
