Epidemiology of syphilis in Kenya: results from a nationally representative serological survey.

OBJECTIVES: The authors used data from the Kenya AIDS Indicator Survey (KAIS) 2007 to determine the prevalence of syphilis and associated risk factors among adults aged 15-64 years. METHODS: KAIS was a nationally representative population-based sero-survey that examined demographic and behavioural indicators and serological testing for syphilis, HIV and herpes simplex virus type 2 (HSV-2) in adults aged 15-64 years. The authors analysed data from 8935 women and 6727 men with complete syphilis results. Logistic regression models stratified by sex were used to assess potential factors associated with syphilis sero-prevalence. RESULTS: Overall, 262 adults tested positive for syphilis (1.8%, 95% CI 1.5% to 2.1%); sero-prevalence was similar among women and men (1.7%, 95% CI 1.3% to 2.0% and 1.9%, 95% CI 1.5% to 2.3%, respectively). Syphilis prevalence was the highest among men with HIV (6.4%, 95% CI 3.1% to 9.7%) and HSV-2 (4.5%, 95% CI 3.4% to 5.7%) infection. Independent risk factors for syphilis included HIV (men only, adjusted OR (AOR) 3.4, 95% CI 1.6% to 7.1%), HSV-2 (women, AOR 3.5, 95% CI 2.1% to 5.8%; men AOR 2.2, 95% CI 1.3% to 3.7%), lack of male circumcision (AOR 2.2, 95% CI 1.3% to 3.7%), poorest or poorer versus richest wealth index (women, AOR 2.0, 95% CI 1.0% to 4.2%; men AOR 2.5, 95% CI 1.4% to 4.9%) and no primary versus secondary or more education in men (AOR 4.8, 95% CI 2.0% to 11.7%). CONCLUSIONS: Syphilis prevalence in the general population in Kenya is relatively low and eradication could be possible but would require intensified syphilis prevention and control efforts, including routine screening in HIV, sexually transmitted infection and antenatal care clinics as well as in family planning and male circumcision settings.

Improving national data collection systems from voluntary counselling and testing centres in Kenya.

PROBLEM: Voluntary counselling and testing (VCT) data from the registered sites in Kenya have been fraught with challenges, leading to insufficient statistics in the national office for planning purposes. An exercise was carried out to determine the barriers to the flow of data in VCT sites in Kenya. APPROACH: A record-based survey was conducted at 332 VCT sites in Kenya. Data from on-site records were compared with those in the national office. The exercise was conducted in 2004 between 5 September and 15 October. LOCAL SETTING: All registered VCT sites in Kenya. RELEVANT CHANGES: After the exercise, various measures to enhance VCT data collection and reporting were implemented. They include the provision of a uniform data collection and reporting tool to all the districts in the country, the strengthening of a feedback mechanism to update provinces and districts on their reporting status and increased support to the data component of the national quality assurance for VCT. LESSONS LEARNED: Periodical field visits by the national officials to offer on-the-job training about data management to data collectors and to address data quality issues can dramatically improve the quality and completeness of VCT reports. The perceived relevance of the data and the data collection process to those working at the sites is the critical factor for data quality and timeliness of reporting.

COVID-19 related knowledge, attitudes, practices and needs of households in informal settlements in Nairobi, Kenya

Objective: Urban slums are at high risk of COVID-19 transmission due to the lack of basic housing, water, and sanitation, and overcrowding. No systematic surveys of slum households' experiences exist to date. Methods: A mobile phone knowledge, attitudes, and practices survey was conducted March 30- 31, 2020. Participants were sampled from two study cohorts across five urban slums in Nairobi, Kenya. Findings: 2,009 individuals (63% female) participated. Knowledge of fever and cough as COVID-19 symptoms was high, but only 42% listed difficulty breathing. Most (83%) knew anyone could be infected; younger participants had lower perceived risk. High risk groups were correctly identified (the elderly - 64%; those with weak immune systems - 40%) however, 20% incorrectly stated children.Handwashing and using hand sanitizer were known prevention methods, though not having a personal water source (37%) and hand sanitizer being too expensive (53%) were barriers.Social distancing measures were challenging as 61% said this would risk income.A third worried about losing income, only 26% were concerned about infecting others if themselves sick. Government TV ads and short message service (SMS) were the most common sources of COVID-19 information and considered trustworthy (by >95%) but were less likely to reach less educated households. Conclusion: Knowledge of COVID-19 is high; significant challenges for behavior change campaigns to reach everyone with contextually appropriate guidance remain. Government communication channels should continue with additional efforts to reach less educated households.A strategy is necessary to facilitate social distancing, handwashing and targeted distributions of cash and food
