Characterisation of Peste Des Petits Ruminants Disease in Pastoralist Flocks in Ngorongoro District of Northern Tanzania and Bluetongue Virus Co-Infection

Peste des petits ruminants (PPR) disease was first confirmed in Tanzania in 2008 in sheep and goats in Ngorongoro District, northern Tanzania, and is now endemic in this area. This study aimed to characterise PPR disease in pastoralist small ruminant flocks in Ngorongoro District. During June 2015, 33 PPR-like disease reports were investigated in different parts of the district, using semi-structured interviews, clinical examinations, PPR virus rapid detection test (PPRV-RDT), and laboratory analysis. Ten flocks were confirmed as PPRV infected by PPRV-RDT and/or real-time reverse transcription-polymerase chain reaction (RT-qPCR), and two flocks were co-infected with bluetongue virus (BTV), confirmed by RT-qPCR. Phylogenetic analysis of six partial N gene sequences showed that the PPR viruses clustered with recent lineage III Tanzanian viruses, and grouped with Ugandan, Kenyan and Democratic Republic of Congo isolates. No PPR-like disease was reported in wildlife. There was considerable variation in clinical syndromes between flocks: some showed a full range of PPR signs, while others were predominantly respiratory, diarrhoea, or oro-nasal syndromes, which were associated with different local disease names (olodua—a term for rinderpest, olkipiei—lung disease, oloirobi—fever, enkorotik—diarrhoea). BTV co-infection was associated with severe oro-nasal lesions. This clinical variability makes the field diagnosis of PPR challenging, highlighting the importance of access to pen-side antigen tests and multiplex assays to support improved surveillance and targeting of control activities for PPR eradication.

Factors influencing adoption of facility-assisted delivery - a qualitative study of women and other stakeholders in a Maasai community in Ngorongoro District, Tanzania

BACKGROUND: Tanzania’s One Plan II health sector program aims to increase facility deliveries from 50% to 80% from 2015-2020. Success is uneven among certain Maasai pastoralist women in Northern Tanzania who resist going to a facility for birth even after completing 4+ ANC visits. Ebiotishu Oondomonok Ongera (EbOO) is a program in Nainokanoka ward to promote facility-births through a care-group model using trained traditional birth attendants (TBAs) as facilitators. Results to date are promising but show a consistent gap between women completing ANC and those going to a facility for delivery. A qualitative study was conducted to understand psychosocial preferences, agency for decision-making, and access barriers that influence where a woman in the ward will deliver. METHODS: In-depth interviews, focus group discussions and key-informant interviews were conducted with 24 pregnant and/or parous women, 24 TBAs, 3 nurse midwives at 3 health facilities, and 24 married men, living in Nainokanoka ward. Interviews and discussions were transcribed, translated, and analyzed thematically using a grounded theory approach. RESULTS: Most women interviewed expressed preference for a home delivery with a TBA and even those who expressed agency and preference for a facility delivery usually had their last delivery at home attributed to unexpected labor. TBAs are engaged by husbands and play a significant influential role in deciding place of delivery. TBAs claim to support facility deliveries but in practice use them as a last resort and reported a significant trust gap based on a bad experience at a facility where women in labor were turned away. CONCLUSIONS: EbOO project data and study results show a slow but steady change in norms around delivery preference in Nainokanoka ward. Gaps between expressed intention and practice, especially around ‘unexpected labor’ present opportunities to accelerate this process by promoting birth plans and perhaps constructing a maternity waiting house in the ward. Rebuilding trust between facility midwives, TBAs, and the community on the availability of health facility services, and increased sensitivity to women’s cultural preferences, could also close the gap between the number of women who are currently using facilities for ANC and those returning for delivery.

Accumulation Tendency, Sustainable Tourism and Hospitality in Tanzania

Sustainable tourism depends on, among others, culture and interaction between members of a given community, flow of tourists and political climate of the host country, and hospitality of the service providers. It assumes that nature of the economy and relation of production and tranquillity define the sustainability of tourism. This paper presents the case of Ngorongoro district where Ngorongoro Conservation Area Authority (NCAA) and Loliondo Game Controlled Area (LGCA) are situated. Resources in these areas were sustained under the local community for centuries before the application of the modern approaches, which involved land alienation. The alienation of land led to the loss of pastures, eviction and relocation of Maasai pastoralists from NCAA. The situation made the pastoralists lose their livelihood options. Some development initiatives were prohibited. Community members started to fight with investors on access to resources. Moreover, search for alternative sources of living drove them into illegal practices of robbing travellers. Indeed, poaching and illegal transfers of wild animals by colluding with those in power made a few individuals benefit from the practices. As a result, the accumulation tendency made the hosting community lose their resources and the livelihood options as well. In this way, the only immediate option was trespassing to the existing resources and users; hence, malfunctioning of the sector. Thus, this paper argues that, in order to realise sustainable tourism and curb the emerging hostility between the resource hosts and the greedy individuals, community participation is paramount.

Rift Valley fever potential mosquito vectors and their infection status in Ngorongoro District in northern Tanzania

Background: Rift Valley fever (RVF) is a mosquito-borne viral zoonotic disease. Rift Valley fever virus (RVFV) has been isolated from more than 40 species of mosquitoes from eight genera. This study was conducted to determine the abundance of potential mosquito vectors and their RVFV infection status in Ngorongoro District of northern Tanzania.Methods: Adult mosquitoes were collected outdoors using the CDC light traps baited with carbon dioxide in five randomly selected villages namely, Meshili, Malambo, Osinoni, Endulen and Nainokanoka. The study was carried out towards the end of rainy season in May 2013. The traps were set in proximity to potential breeding sites and cattle kraals. The collected mosquitoes were identified to genus and species using morphological keys. They were tested for RVFV RNA using real time reverse transcription-polymerase chain reaction (rRT-PCR).Results: A total of 2,094 adult mosquitoes belonging to three genera and nine species were collected. Most of them (87.5%) were collected in Meshili, followed by Malambo (8.2%) and Osinoni (4%) villages. No single mosquito was collected in Nainokanoka or Endulen. The nine species collected were Culex pipiens complex, Cx. antennatus, Cx. tigripes, Cx. annulioris, Cx. cinereus, Anopheles arabiensis, An. squamosus, An. pharoensis and Mansonia uniformis. No RVFV RNA was detected in the mosquito specimens.Conclusion: Various RVFV potential mosquito species were collected from the study villages. These mosquito vectors were heterogeneously distributed in the district suggesting a variation in RVF transmission risk in the study area.
