Human papillomavirus prevalence among unvaccinated young female college students in Botswana: A cross-sectional study.

BACKGROUND: Human papillomavirus (HPV) is a sexually transmitted infection and a causative agent of cervical cancer. It is common in adolescent girls and young women, and the majority of infections are transient and asymptomatic. In Botswana, there are currently no data on the HPV prevalence against which the impact of prophylactic HPV vaccines can be measured. OBJECTIVES: To establish a baseline HPV prevalence in an unvaccinated cohort of young women. METHODS: Women aged ≥18 years were recruited from the University of Botswana between September 2016 and May 2020. Demographic and behavioural characteristics of participants were collected. Subsequently, cervicovaginal swabs were obtained and tested for HPV using polymerase chain reaction-restriction fragment length polymorphism. We determined the prevalent HPV types, and evaluated the risk factors associated with HPV positivity. RESULTS: A total of 978 young women were recruited. Overall, there were 589 (60.2%) participants with HPV infection and 12 (1.2%) with HIV. The median (interquartile range) age of the study participants was 19 (18 - 20) years. Multivariate logistic regression analysis showed that significant factors associated with HPV positivity were sexual activity (adjusted odds ratio (aOR) 2.06; 95% confidence interval (CI) 1.49 - 2.63; p<0.001), number of sex partners ≥3 (aOR 2.10; 95% CI 1.39 - 3.18; p<0.001), and smoking (aOR 2.00; 95% CI 1.26 - 3.20; p=0.004). CONCLUSION: Our results demonstrate for the first time the prevalence of HPV in unvaccinated young women in Botswana. We found a high prevalence of HPV infection, with statistical differences with different risk factors. This finding supports the need for HPV vaccination strategies for females prior to sexual debut to reduce the future burden of cervical cancer in Botswana.

Results from the first audit of an intensive care unit in Botswana.

Background: Botswana is an economically stable middle-income country with a developing health system and a large HIV and infectious disease burden. Princess Marina Hospital (PMH) is the largest referral and teaching hospital with a mixed eight-bed intensive care unit (ICU). Objectives: To conduct an audit of PMH ICU in order to investigate major admission categories and quantify morbidity and mortality figures using a validated scoring system for quality improvement, education and planning purposes. Methods: PMH medical records and laboratory data were accessed to record demographics, referral patterns, diagnoses, HIV status, Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) II scores and mortality rates. Results: A total of 182 patients >14 years of age were enrolled over a 12-month period from April 2017 - March 2018. Patient's mean age was 42.9 years, males represented 56.6% of the study population and surgical conditions accounted for 46% of diagnostic categories. Sixty percent of the patients were HIV-negative and 12% had no HIV status recorded. The mean APACHE II score was 25 and the mean length of stay in ICU was 10.3 days. Higher APACHE II scores were associated with higher mortality regardless of HIV status. The overall mortality was 42.8% and there was no difference in mortality rates in ICU or at 30 days between HIV-positive and HIV-negative ICU patient groups. Conclusion: The PMH ICU population is young with a high mean APACHE II score, significant surgical and HIV burdens and a high mortality rate. PMH ICU has significant logistical challenges making comparison with international ICUs challenging, and further research is warranted. Contributions of the study: This study is the first published audit for an intensive care unit in Botswana. The findings are especially relevant for the development of critical care capacity in the country during the current COVID-19 pandemic. We advocate for the establishment of an ICU registry in the country to allow ongoing accurate research in the field of critical care medicine and to improve healthcare for all critically ill patients in Botswana.
