Item Operationalization of COVID-19 Rapid Diagnosis Using Xpert® Xpress SARS CoV-2 Assay in Resource-Limited Settings: Early Implementation Lessons From Uganda(Research Square, 2021) Nsawotebba, Andrew; Ibanda, Ivan; Ssentalo Bagaya, Bernard; Nyombi, Abdunoor; Kagirita, Atek; Tugumisirize, Didas; Mujuni, Dennis; Majwala, Robert Kaos; Ocen, Francis; Kabugo, Joel; Adam, Isa; Wekiya, Enock; Munduku, Benoni; Linda, Lillian; Kalyesubula-Kibuuka, Simon; Okiira, Christopher; Kigozi, Edgar; Ogwok, Patrick; Lutakoome Joloba, Moses; Nabadda, Susan; Ssengooba, WillyThe novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) that causes COVID-19 disease is a global challenge. Several countries have adopted testing, isolation, and tracing strategy towards the control of the COVID-19 pandemic, but access to rapid and accurate testing is still a global challenge. The conventional PCR – based assay is the most commonly used test yet it has huge costs, infrastructural, and procurement logistical challenges. The Xpert® Xpress SARS-CoV-2 test is an automated in – vitro diagnostic test for the qualitative detection of nucleic acid from SARS-CoV-2 within a turnaround time of 60 minutes on the widely used GeneXpert Dx Instrument Systems. Here we document the best practices and challenges encountered with the operationalization of Xpert® Xpress SARS-CoV-2 testing in a resource-limited setting. Materials and Methods: The Xpert® Xpress SARS-CoV-2 implementation followed an operational work plan that included; Laboratory COVID-19 policy and planning, situational analysis of the Laboratory network, country Xpert® Xpress SARS-CoV-2 assay verification, and rollout at Mutukula Port Health Laboratory. The Laboratory strategy was based on a set of six objectives; conducting infrastructural modifications, building a strong COVID-19 testing capacity, developing robust Laboratory Quality and Information Management Systems, establishing a Bio-risk management and Bio-banking capacity.Item Prevalence and correlates of HIV infection among adolescents and young people living in fishing populations along Lake Victoria Fishing Communities in Uganda(Pan African Medical Journal, 2020) Nanyonjo, Gertrude; Asiki, Gershim; Ssetaala, Ali; Nakaweesa, Teddy; Wambuzi, Mathias; Nanvubya, Annet; Mpendo, Juliet; Okech, Brenda; Kato Kitandwe, Paul; Nielsen, Leslie; Nalutaaya, Annet; Welsh, Sabrina; Ssentalo Bagaya, Bernard; Chinyenze, Kundai; Fast, Pat; Price, Matt; Kiwanuka, Noahfishing communities in Uganda are key populations for HIV, with persistently higher prevalence and incidence than the general population. Methods: between March and August 2014, a cross sectional survey was conducted in 10 fishing communities of Lake Victoria in Uganda. Data was collected on socio-behavioural characteristics using interviewer administered questionnaires and venous blood collected for HIV testing. Prevalent HIV infections among adolescents and young people aged 13 to 24 years was estimated and the factors associated with those infections determined using multi variable logistic regression modelling. Results: HIV prevalence was 10.8% among the 630 (96.5%) who provided a blood sample. Females were 3.5 times as likely to have HIV infection as males (aOR=3.52, 95% CI: 1.34-9.22). Young people aged 20-24 years were twice as likely to be HIV infected as those aged 13-19 years (aOR=1.77, 95% CI: 0.05-2.10), participants without formal education or those who had studied up to primary level were more likely to be HIV infected than those who had post primary education ((aOR=2.45, 95% CI: 1.19-5.07) or (5.29 (1.35-20.71) respectively). Reporting more than one sexual partner in the past 6 months was associated with HIV prevalent infection than those reporting no sexual partners (aOR=6.44, 95% CI: 1.27-32.83). Conclusion: adolescents and young people aged 13-24 years in fishing communities around Lake Victoria, Uganda, have a high HIV prevalence, with females having a three-fold higher level than males. These findings highlight the need to improve HIV prevention among young females living in these fishing communities.
