Background Kenya has an estimated 13,000 new infant HIV infections that occur annually. We measured the burden of HIV infection among women of childbearing age and assessed access to and coverage of key prevention of mother-to-child transmission interventions. Methods The second Kenya AIDS Indicator Survey was a nationally representative 2-stage cluster sample of households. We analyzed data from women aged 15–54 years who had delivered a newborn within the preceding 5 years and from whom we obtained samples for HIV testing. Results Of 3310 women who had ≥1 live birth in the preceding 5 years, 2862 (86.5%) consented to HIV testing in the survey, and 171 (6.1%) were found to be infected. Ninety-five percent received pre-natal care, 93.1% were screened for HIV during prenatal care, and of those screened, 97.8% received their test results. Seventy-six women were known to be infected in their last pregnancy. Of these, 54 (72.3%) received antepartum antiretroviral prophylaxis, and 51 (69.1%) received intrapartum prophylaxis; 56 (75.3%) reported their newborns received postpartum prophylaxis. Of the 76 children born to these mothers, 63 (82.5%) were tested for HIV at the first immunization visit or thereafter, and 8 (15.1%) were HIV infected. Conclusions We found a substantial burden of HIV in Kenyan women of childbearing age and a cumulative 5-year mother-to-child transmission rate of 15%. Although screening has improved over the past 5 years, fewer than three-quarters of infected pregnant women are receiving antiretroviral prophylaxis. Universal antiretroviral therapy for HIV-infected pregnant women will be essential in achieving Kenyan’s target to eliminate mother-to-child transmission to <5% by 2015.

Problem/ConditionUse of human immunodeficiency virus (HIV)-mortality surveillance data can help public health officials monitor, evaluate, and improve HIV treatment programs. Many high-income countries have high-coverage civil registration and vital statistics (CRVS) systems linked to case-based HIV surveillance on which to base HIV mortality estimates. However, in the absence of comprehensive CRVS systems in low- and medium-income countries, such as Kenya, mortuary surveillance can be used to understand the occurrence of HIV infection among cadavers. In 2015, a pilot HIV-related mortuary surveillance system was implemented in the two largest mortuaries in Nairobi, Kenya. CDC conducted an evaluation to assess performance attributes and identify strengths and weaknesses of the surveillance system pilot.Period CoveredData collection: January 29–March 3, 2015; evaluation: November 2015.Description of the SystemThe surveillance system objectives were to determine HIV positivity among cadavers at two mortuary sites in Nairobi, Kenya, and to determine annual cause-specific and HIV-specific mortality rates among the cadavers. Cadavers of persons aged ≥15 years at death admitted to either mortuary during a 33-day period were included. Demographic information and place and time of death were entered into a surveillance register. Cardiac blood was collected using transthoracic aspiration, and blood specimens were tested for HIV in a central laboratory. Causes of death were abstracted from mortuary and hospital records. Of the 807 cadavers brought to the mortuaries, 610 (75.6%) had an HIV test result available. The overall unadjusted HIV-positivity rate was 19.5% (119/610), which differed significantly by sex (14.6% among men versus 29.5% among women).EvaluationThe evaluation was conducted using CDC guidelines for evaluating public health surveillance systems. The attributes of simplicity, flexibility, data quality (completeness and validity), acceptability, sensitivity, predictive value positive, representativeness, timeliness, and stability were examined. The evaluation steps included review of the surveillance system documents, in-depth interviews with 20 key informants (surveillance system staff, including mortuary and laboratory staff, and stakeholders involved in funding or implementation), and review of the surveillance database.Results and InterpretationImplementation of the pilot mortuary surveillance system was complex because of extensive paperwork and the need to collect and process specimens outside of business hours. However, the flexibility of the system accommodated multiple changes during implementation, including changes in specimen collection techniques and data collection tools. Acceptability was initially low among the mortuary staff but increased after concerns regarding workload were resolved. Timeliness of specimen collection could not be measured because time of death was rarely documented. Completeness of data available from the system was generally high except for cause of death (46.5%). Although t...

Understanding the characteristics of individuals who are newly diagnosed with HIV is critical to controlling the HIV epidemic. Characterizing this population can improve strategies to identify undiagnosed positives and assist in targeting the provision of HIV services to improve health outcomes. We describe the characteristics of newly diagnosed HIV cases in western Kenya from 124 health facilities. The study cohort cases were matched to prevent duplication and patients newly diagnosed between January and June 2015 were identified and descriptive analysis performed. Among 8664 newly identified HIV cases, during the pilot timeframe, 3.1% (n=265) had retested for HIV after initial diagnosis. Linkage to care was recorded for approximately half (45.3%, n = 3930) and 28.0% (n = 2425) had a CD4 count available during the pilot timeframe. The median baseline CD4 count was 332 cells/mL (IQR: 156–544). Among the newly diagnosed age 15 years or older with a CD4 test, 53.0% (n = 1216) were diagnosed late, including 32.9% (n = 755) who had advanced HIV at diagnosis. Factors associated with late diagnosis included being male and in an age group older than 34 years. In western Kenya, continued efforts are needed in the area of testing to enhance early HIV diagnosis and epidemic control.

Homa Bay County in south-western Kenya has a low uptake of antenatal care services and the highest prevalence of HIV in the country. We present the findings of a retrospective review of HIV-exposed infants (HEI) who sought early infant diagnosis services in the county throughout 2015. HEI who were breastfed >6 months, had replacement feeding and did not receive prophylaxis were 2–6 times more likely to be HIV-positive.
