Application of the UNAIDS Incidence Patterns Model to Determine the Distribution of New HIV Infection in Lagos State, Nigeria

BACKGROUND

Identifying patterns in the distribution of new HIV infections in the population is critical for HIV programmatic interventions. This study aimed to determine the distribution of New HIV infection by applying the incidence patterns mathematical model to data from Lagos state.

METHODS

The incidence patterns model (IPM) software is a mathematical model developed by UNAIDS to estimate the demographic and epidemic patterns of HIV infections. This model was adapted in Lagos state to predict the distribution of new HIV infections among specified risk groups in the next 12 months.

RESULTS

The IPM predicted a total HIV incidence of 37 cases per 100 000 individuals (3979 new infections) will occur among the 15 to 49 subpopulations. The results also showed that sero-concordant HIV-negative couples with external partners (29%), female sex workers (26%), men-having-sex-with-men (18%), and previously married females (6%) accounted for the majority of the estimated new HIV infections. Overall, key populations constitute almost half (48%) of the estimated number of new HIV infections.

CONCLUSION

The study helped to identify the population groups contributing significantly to new HIV infections. Therefore, priority interventions should be focused on these groups.

How Do People Living With HIV (PLHIV) and AIDS Feel About the Quality of Care They Received Amid the COVID-19 Pandemic in Lagos, Nigeria?

Background: This study aimed to assess the perception of quality of care among people living with HIV (PLHIV) in Lagos, Nigeria, and identify factors influencing their perceptions. Methodology: The study was a descriptive cross-sectional survey conducted between December 2020 and March 2021 among 578 PLHIVs drawn from various healthcare facilities in Lagos where HIV care and treatment services were provided. Data were collected through pretested questionnaires and analyzed using Stata SE 12. Results: About 83% of the respondents had a good attitude toward their HIV medication, and 95.5% had a good perception of the quality of care they received. PLHIVs with higher education, skilled or professional occupations and higher monthly income had a significantly higher perception of quality of care compared to others (P < .05). Conclusion: The PLHIV in Lagos had a positive attitude toward their medication and a good perception of the quality of care they received during the COVID-19 pandemic. All stakeholders' efforts should be sustained for continuous quality improvement in HIV care in Lagos.

Urinary schistosomiasis transmission in Epe, an urban community of Southwest Nigeria

Background:

A survey of Schistosoma haematobium infection in Epe, an urban community in Lagos State, Southwest Nigeria, was carried out to ascertain the possibility that schistosomiasis, otherwise considered a rural disease, could reach urban populations.

Materials and Methods:

About 100 ml of voided urine samples from 200 pupils aged 6–13 years [109 (54.5%) males and 91 (45.5%) females], attending an Anglican primary school, Ebute Afuye, and a community primary school, Erepoto, were examined parasitologically for hematuria and S. haematobium ova following informed consent obtained from their parents/guardians. All samples were screened using polymerase chain reaction (PCR) amplification of the schistosome Dra1 gene. Fourteen Bulinus snails collected from the two sites, Ebute Afuye (6) and Erepoto (8), were screened for schistosome infection by the PCR amplification of the schistosome Dra1 gene. PCR-RFLP of the snails’ its region was analyzed for species identification and a subregion of the cox1 gene from four infected snails (two from each site) was amplified and sequenced.

Results:

In the Anglican primary school, Ebute Afuye, and community primary school, Erepoto, 16% and 29% were positive for hematuria, and 16% and 17% had schistosome ova, respectively. PCR analysis showed that 57% and 40% were positive for the infection in Anglican primary school, Ebute Afuye, and community primary school, Erepoto, respectively. PCR screening of the snails confirmed that four from Ebute Afuye and three from Erepoto were infected with schistosomes. PCR-RFLP showed that all the 14 snails were Bulinus truncatus while phylogenetic analysis of the sequenced partial cox1 gene corroborated the PCR-RFLP results.

Conclusions:

There was a high prevalence of S. haematobium infection among the participants detected by PCR, which was able to detect infection in cases otherwise shown to be negative by hematuria. We also observed that B. truncatus is one of the snail species responsible for the transmission of urinary schistosomiasis in the Epe community. For national control programs, it is very important that trends in the prevalence and intensity of schistosomiasis in urban cities be monitored.
