How well does the process of screening and diagnosis work for HIV-infected persons identified with presumptive tuberculosis who are attending HIV care and treatment clinics in Harare city, Zimbabwe?

Background: Intensified TB case finding is recommended for all HIV-infected persons regularly attending HIV care and treatment clinics. The authors aimed to determine how well this system worked among HIV-infected patients diagnosed with presumptive TB in 14 health facilities of Harare province, Zimbabwe, between January and December 2016. Methods: Retrospective review using routine programme records. Results: Of 47 659 HIV-infected persons enrolled in HIV care, 102 were identified with presumptive TB through the programmatic electronic database. Of these, 23% (23/102) were recorded in presumptive TB registers and, of these 65% (15/23) were traced to laboratory registers. Of 79 patients not recorded in presumptive TB registers, 9% (7/79) were traced to laboratory registers. Of 22 patients in the laboratory register, all had negative sputum smears for acid-fast bacilli and 45% (10/22) had Xpert MTB/RIF assays with one positive result. Six patients altogether started anti-tuberculosis treatment, the median time from presumptive tuberculosis diagnosis to treatment being 12 days. The only significant risk factor for loss-to-follow-up between presumptive TB diagnosis and laboratory registration was not being recorded in presumptive TB registers. Conclusions: Follow-up mechanisms for presumptive TB cases diagnosed in HIV care clinics in Harare city need strengthening, particularly through improved documentation in presumptive TB registers and better Xpert MTB/RIF use

Declining Trends in Childhood TB Notifications and Profile of Notified Patients in the City of Harare, Zimbabwe, from 2009 to 2018.

Globally, childhood tuberculosis (TB among those aged <15 years) is a neglected component of national TB programmes in high TB burden countries. Zimbabwe, a country in southern Africa, is a high burden country for TB, TB-HIV, and drug-resistant TB. In this study, we assessed trends in annual childhood TB notifications in Harare (the capital of Zimbabwe) from 2009 to 2018 and the demographic, clinical profiles, and treatment outcomes of childhood TB patients notified from 2015-2017 by reviewing the national TB programme records and reports. Overall, there was a decline in the total number of TB patients (all ages) from 5,943 in 2009 to 2,831 in 2018. However, the number of childhood TB patients had declined exponentially 6-fold from 583 patients (117 per 100,000 children) in 2009 to 107 patients (18 per 100,000 children) in 2018. Of the 615 childhood TB patients notified between 2015 and 2017, 556 (89%) patient records were available. There were 53% males, 61% were aged <5 years, 92% were new TB patients, 85% had pulmonary TB, and 89% were treated for-drug sensitive TB, 3% for drug-resistant TB, and 40% were HIV positive (of whom 59% were on ART). Although 58% had successful treatment outcomes, the treatment outcomes of 40% were unknown (not recorded or not evaluated), indicating severe gaps in TB care. The disproportionate decline in childhood TB notifications could be due to the reduction in the TB burden among HIV positive individuals from the scale up of antiretroviral therapy and isoniazid preventive therapy. However, the country is experiencing economic challenges which could also contribute to the disproportionate decline in childhood TB notification and gaps in quality of care. There is an urgent need to understand the reasons for the declining trends and the gaps in care

Household water treatment uptake during a public health response to a large Typhoid Fever outbreak in Harare, Zimbabwe

Locally manufactured sodium hypochlorite (chlorine) solution has been sold in Zimbabwe since 2010. During October 1, 2011–April 30, 2012, 4,181 suspected and 52 confirmed cases of typhoid fever were identified in Harare. In response to this outbreak, chlorine tablets were distributed. To evaluate household water treatment uptake, we conducted a survey and water quality testing in 458 randomly selected households in two suburbs most affected by the outbreak. Although 75% of households were aware of chlorine solution and 85% received chlorine tablets, only 18% had reportedly treated stored water and had the recommended protective level of free chlorine residuals. Water treatment was more common among households that reported water treatment before the outbreak, and those that received free tablets during the outbreak (P < 0.01), but was not associated with chlorine solution awareness or use before the outbreak (P > 0.05). Outbreak response did not build on pre-existing prevention programs.The U.S. Centers for Disease Control and Prevention Division of Global Disease Detection and Emergency Response, the U.S. Agency for International Development’s Office of U.S. Foreign Disaster Assistance, the United Nations Children’s Fund-Zimbabwe, Welthungerhilfe- Zimbabwe, and Population Services International-Zimbabwe.http://www.ajtmh.orgam201

Enhanced adherence counselling and viral load suppression in HIV seropositive patients with an initial high viral load in Harare, Zimbabwe: Operational issues.

BACKGROUND:In people living with HIV (PLHIV) who are on anti-retroviral therapy (ART), it is essential to identify persons with high blood viral loads (VLs) (≥1000 copies/ml), provide enhanced adherence counselling (EAC) for 3 months and assess for VL suppression (5,000 copies/ml were associated with lower probability of viral suppression. CONCLUSION:The routine VL testing levels were high, but there were major programmatic gaps in enrolling PLHIV with high VLs into EAC and achieving VL suppression. The full potential of EAC on achieving viral load suppression has not been achieved in this setting. The reasons for these gaps need to be assessed in future research studies and addressed by suitable changes in policies/practices
