Entomological survey of mosquito vectors was carried out to determine species abundance and identify those responsible for the transmission of lymphatic filariasis in Talatan-mafara and Tsafe Local Government Areas of Zamfara State, Nigeria. Houses were randomly selected for mosquito collection. Aerosol (Baygon) was sprayed in the rooms to knockdown indoor resting mosquitoes. A total of 5,230 mosquitoes comprising of 3,104 females and 2,126 males were collected and 1,182 engorged females were dissected to isolate filarial worm, Wuchereria bancrofti. The species of mosquitoes encountered include Culex quinquefasciatus (84%), Anopheles funestus (10%) and Anopheles gambiae sl. (6%). The overall infection and infectivity rates of the mosquitoes with Wuchereria bancrofti were 1.86% and 1.44% respectively. The infection/infectivity rates of Culex quinquefasciatus, Anopheles funestus and Anopheles gambiae sl. were 1.01%/0.51%, 2.97%/2.97% and 4.54%/4.14% respectively.

Background: Lymphatic filariasis is a pervasive and life-threatening disease for human beings. Currently, 893 million people in 49 countries worldwide affected by lymphatic filariasis as per WHO statistics. The concealed aspects of lymphatic diseases such as delayed disease detection, inappropriate disease imaging, the geographical outbreak of infection, and lack of preventive chemotherapy have brought this epidemic to the edge of Neglected Tropical Diseases. Many medications and natural bioactive substances have seen to promote filaricidal activity against the target parasitic species. However, the majority of failures have occurred in pharmaceutical and pharmacokinetic issues. Objective: The purpose of the study is to focus on the challenges and therapeutic issues in the treatment of filariasis. The review brings novel techniques and therapeutic approaches for combating lymphatic filariasis. It also offers significant developments and opportunities for such therapeutic interventions. Conclusion: Through this review, an attempt has made to critically evaluate the avenues of innovative pharmaceuticals and molecular targeting approaches to bring an integrated solution to combat lymphatic filariasis.

Background: Lymphatic filariasis (LF) is a parasitic disease that has been targeted for elimination through the Mass Drug Administration (MDA.) Although the MDA started in the Ankobra community in Ghana in 2000, LF prevalence as reported in 2014 was relatively high (4.5%). Non-compliance to the MDA has been associated with the persistent LF prevalence in endemic regions. Objective: This study determined the factors associated with the non-compliance to the MDA among patients living in the Ankobra community, Ghana. Methods: A cross-sectional study using a one-stage cluster sampling method was used to collect data between June and July, 2017 in Ankobra. Questionnaires were used to collect data from health workers, the MDA drug distributors and study participants in Ankobra. Data analysis was performed using STATA 14. Logistic regression was used to measure the degree of association between the dependent (non-compliance) and independent variables. Non-compliance rate was defined as the percentage of individuals who self-reported that they did not actually swallow the drugs provided during the MDA. Results: The MDA coverage and non-compliance rates were 73.5% (147/200) and 33.33% (49/147) respectively. The main reason for non-compliance was fear of drug adverse events (75.51%, 37/49). Thought of “not being susceptible to LF” was significantly associated with the non-compliance (aOR= 2.83, [CI= 1.15, 6.98]). Conclusion: Health education about the susceptibility of residents getting LF disease in endemic community must be intensified to improve compliance to MDA medication ingestion and thus meet the Global Elimination of Lymphatic Filariasis by 2020.

Migrant Groups

Abstract Background In March 2017, Togo was declared the first country in sub-Saharan Africa to eliminate lymphatic filariasis as a public health problem, but post-validation surveillance has been lacking. In some areas of the country, migrant groups from neighboring countries that are still endemic for LF pose a risk of reintroduction of LF to Togo. The objective of this study was to identify the risk posed by migrant groups by measuring their prevalence of LF infection and investigating any positive case using Togo’s case investigation algorithm to prevent resurgence of LF and sustain Togo’s elimination success. Method A cross-sectional study was conducted in 2018 in the northernmost region of the country. Three migrant populations were identified: (i) nomadic Peuhls, (ii) Togolese members of local communities who migrate annually to neighboring countries for seasonal labor, and (iii) refugees from Ghana who came to Togo because of a communal conflict in Ghana. A questionnaire was designed to collect data on demographics and history of LF and MDA; all participants were tested for circulating filariasis antigen (CFA) using the filariasis test strip (FTS). Any CFA-positive case was confirmed with nocturnal microfilaremia. Results Refugees, seasonal economic migrants and nomadic Peuhls represented 42.1%, 31.4% and 26.5% of the study participants, respectively. The overall prevalence of CFA was 4.2% (58/1391) with the highest prevalence in the nomadic Peuhl group (11.9%), but only one of them (0.07%) was confirmed positive with nocturnal microfilaremia. Using the case investigation algorithm, no other positive case was identified in the positive case’s surroundings. Conclusion This study demonstrates that nomadic Peuhls, with a CFA prevalence of 11.9%, pose a potential risk for reintroduction of LF into Togo while Ghanaian refugees and seasonal economic migrants do not appear to pose a significant risk. Periodic monitoring of migrants, especially the nomadic Peuhl population, is a potential post-validation surveillance approach that could be used to promptly detect any LF cluster that may arise.

Abstract We conducted an implementation research study to integrate a holistic package of physical health, mental health and psychosocial care for podoconiosis, lymphatic filariasis and leprosy into routine healthcare in Gusha cluster, Guagusa Shikudad district, northwest Ethiopia. The healthcare package included training patients in lower limb hygiene and skin care and provision of shoes, hygiene supplies and medication. The implementation activities included training events, workshops, awareness raising, self-help groups, supportive supervision, staff secondments and advisory board meetings. The cost of implementing the care package in Gusha cluster, with a population of 30 558 people, was 802 655 Ethiopian birr (ETB) (£48 159) and the cost of delivering care to 235 participants was 204 388 ETB (£12 263), or 870 ETB (£52) per person. There was a 35% decrease in the mean disability scores (measured using the World Health Organization Disability Assessment Schedule 2.0) and a 45% improvement in the dermatology-specific quality of life (measured using the Dermatology Life Quality Index) at the 3-month follow-up compared with baseline. There were reductions in the number of days with symptoms, days off usual activities/work and days with reduced activity due to illness, all of which were statistically significant. Our pilot suggests that integration of the care package into routine healthcare in Ethiopia may be effective in improving health-related quality of life and disability and reducing time out of economic activity due to illness.

Abstract Background Studying the characteristics of Aedes mosquito habitats is essential to control the mosquito population. The objective of this study was to identify the breeding sites of Aedes larvae and their distribution in Chattogram, Bangladesh. We conducted an entomological survey in 12 different sub-districts (Thana) under Chattogram City, during the late monsoon (August to November) 2019. The presence of different wet containers along with their characteristics and immature mosquitoes was recorded in field survey data form. Larvae and/or pupae were collected and brought to the laboratory for identification. Results Different indices like house index, container index, and the Breteau index were estimated. The multiple logistic regression analysis was applied to identify habitats that were more likely to be positive for Aedes larvae/pupae. A total of 704 wet containers of 37 different types from 216 properties were examined, where 52 (7.39%) were positive for Aedes larvae or pupae. Tire, plastic buckets, plastic drums, and coconut shells were the most prevalent container types. The plastic group possessed the highest container productivity (50%) whereas the vehicle and machinery group was found as most efficient (1.83) in terms of immature Aedes production. Among the total positive properties, 8% were infested with Aedes aegypti, 2% with Aedes albopictus, and 1% contained both species Ae. aegypti and A. albopictus. The overall house index was 17.35%, the container index was 7%, and the Breteau index was 24.49. Containers in multistoried houses had significantly lower positivity compared to independent houses. Binary logistic regression represented that containers having shade were 6.7 times more likely to be positive than the containers without shade (p< 0.01). Conclusions These findings might assist the authorities to identify the properties, containers, and geographical areas with different degrees of risk for mosquito control interventions to prevent dengue and other Aedes-borne disease transmissions.
