HIV care among patients with presumptive tuberculosis in Masvingo district of Zimbabwe, 2017: how well are we doing?

INTRODUCTION: While HIV care among tuberculosis (TB) patients is successfully implemented and monitored, it is not routinely reported among "presumptive TB patients without TB". The present study describes the ascertainment of HIV status and receipt of antiretroviral therapy (ART) and the associated factors among presumptive TB patients (with and without TB) in 35 public health facilities of Masvingo district of Zimbabwe from January to June 2017. METHODS: This was an analysis of secondary programme data. We performed log binomial regression to calculate adjusted relative risks (aRR) and 95% confidence intervals (CI). RESULTS: Of 1369 presumptive TB patients, 1181 (86%) were ascertained for HIV status (98% among those subsequently diagnosed with TB, 83% among non-TB). Of them, 748 (63%) were HIV positive, more among TB patients (69%) than those without TB (61%). Among HIV-positive patients, 475 (64%) received ART, significantly higher among TB patients (78%) compared to those without TB (57%). Patients without TB were significantly more likely to have non-ascertained for HIV status (aRR=2.4, 95% CI=1.4-5.0) and not receiving ART (aRR=1.8, 95% CI=1.6-2.0), compared to those with TB. CONCLUSION: We found high rates of HIV status ascertainment among presumptive TB patients. But, ART uptake was poor among "presumptive TB patients without TB", despite implementation of "test and treat" strategy in Zimbabwe. The programme should step up the monitoring of HIV status and ART receipt among presumptive TB patients, by introducing an indicator in the quarterly reports of the national TB programme.

Evaluation of the acute flaccid paralysis (AFP) surveillance system in Mwenezi district, Masvingo, 2018: a descriptive study.

OBJECTIVES: Poliomyelitis is an infectious disease caused by the polio virus which affects mostly young children below the age of 15 years. For surveillance children with acute flaccid paralysis (AFP) are tracked. In Zimbabwe every district should report two cases per 100,000 population of children under the age of 15 years old. In 2017, Mwenezi district failed to detect any AFP cases. We therefore evaluated the AFP surveillance system in Mwenezi district. We conducted a surveillance system evaluation using the updated Centers for Disease Control guidelines for evaluating public health surveillance systems. We interviewed health workers in Mwenezi district and looked at AFP records from January to December 2017. RESULTS: The main reasons for failure to report a case in 2017 were the vastness of the district with bad road networks as well as lack of a dedicated vehicle to carry out EPI outreach activities. About a quarter, 24%, of the health workers did not know the specimen that is used in AFP diagnosis. The AFP surveillance system in Mwenezi district was performing poorly due to lack of active search of cases in the community caused by disruption of EPI outreach activities.
