Milk producers’ awareness of milk-borne zoonoses in selected smallholder and commercial dairy farms of Zimbabwe

Abstract: A cross-sectional questionnaire-based study was conducted to assess milk producers’ awareness of milk-borne zoonoses in selected smallholder and commercial dairy farms of Zimbabwe. The questionnaire was designed to obtain information on dairy breeds, milk production, dairy farmers’ knowledge and awareness of zoonoses with particular emphasis on milk-borne zoonoses and farmers’ behavioural practices that may lead to increased risk of milk-borne zoonoses transmission. A total of 119 dairy farmers were interviewed, and 41.5% were aware of milk-borne zoonoses with a significantly (P < 0.01) higher percentage of commercial dairy farmers (65.0%) being aware compared to smallholder dairy farmers (36.7%). The behavioural practices of dairy farmers observed to increase the risk of milk-borne zoonoses transmission were; consumption of raw milk (68.1%), sale of raw milk to the local public (25.2%), lack of cooling facilities by smallholder farmers (98%), and no routine testing (84.9%) and medical check-ups (89.1%) for milk-borne zoonoses. General hygienic and disease control practices need to be integrated in the milk production process particularly at the smallholder level. Awareness, teaching and training programmes for smallholder dairy farmers can improve disease control in animals and reduce the public health risk of milk-borne zoonoses.

Routine prophylactic antibiotic use in the management of snakebite

Abstract: Routine antibiotic prophylaxis following snakebite is not recommended but evidence suggests that it may be common practice in Zimbabwe. This study set out to determine and describe the extent of this practice at Parirenyatwa Hospital, a large teaching hospital in Zimbabwe A retrospective case review (1996 to 1999 inclusive) of all cases of snakebite was undertaken at Parirenyatwa Hospital. Cases with a diagnosis of snakebite, presenting within 24 hours of the bite and with no complications or concurrent illness were defined as "routine prophylactic antibiotic use". From 78 cases which satisfied the inclusion criteria, 69 (88.5%) received antibiotics. Ten different antibiotics from 6 different classes were used with penicillins the most commonly prescribed (benzylpenicillin in 29% of cases, alone or in combination). Over 40% of antibiotics were given parenterally although all patients were conscious on admission. The total cost of antibiotics used was estimated at US$522.98. Routine prophylactic use of antibiotics in snakebite at Parirenyatwa Hospital is common practice. This may highlight the lack of a clearly defined policy leading to wasteful inappropriate antibiotic use which is costly and may promote bacterial antibiotic resistance. Further work is required to investigate the reasons for this practice and to design appropriate interventions to counter it.

HIV-1 Seroconversion Incidence Following Pregnancy and Delivery Among Women Seronegative at Recruitment in Harare, Zimbabwe

Abstract: Objective: To estimate the incidence of HIV sero-conversion among women following pregnancy and' delivery. Design: A prospective cohort of women who were HIV negative at recruitment on first antenatal care visit. Materials and Methods: Pregnant women were invited to undergo voluntary confidential HIV counseling and blood draw for HIV testing during the first antenatal care visit as part of a prospective study of mother- to-child transmission of HIV-1. Repeat tests were conducted at delivery, six weeks post partum and at three monthly intervals until 24 months or on termination due to subsequent pregnancy, death or loss to follow up. Logistic regression modelling was used to determine independent predictors of HIV sero-conversion. Results: Among 372 HIV negative pregnant women who were enrolled, 66 sero-converted during follow up, resulting in a sero-incidence of 4.8 per 100 person years (95% confidence interval [Cl], 3.1 to 6.5). Women who did not seroconvert during the time of pregnancy or follow up were significantly more likely to have used a condom with their partners (OR = 0.68,95% Cl = 0.47 to 0.99). Women aged 17 years and below had the highest sero-conversion incidence (6.25%) followed by those aged 18 to 19 years (5.42%). Women who sero-converted and those who were HIV positive at recruitment were more likely to be married. Lack of education by the partner of a pregnant woman constituted a significant risk factor for HIV sero-conversion (OR = 2.8; 95% Cl = 1.1 toll.0). Conclusions: There is a high HIV sero-conversion incidence among women during pregnancy and following delivery, especially those aged 19 years and below. Being married does not protect the women from the risk of HIV sero-conversion. Strategies for HIV prevention should target pregnant women and their partners.

Beyond Sugar Daddies: Intergenerational Sex and AIDS in Urban Zimbabwe

Abstract: In a survey of 1,313 men reporting on 2,465 partnerships recruited at beer halls in Harare, Zimbabwe, 2.5% met a definition of “sugar daddy”: men with a non-marital partner at least 10 years younger and under 20 years old, and exchanged cash or goods for sex. Men engaging in intergenerational sex with a teenage woman had similar HIV prevalence, incomes, and condom use as men in other partnerships. Most men (62.3%) had partners 5 or more years younger, with wider age gaps in longer-term relationships. Condom use was less common within married and steady partnerships compared to casual and more common with younger women. The most common form of intergenerational sex, with the widest age gap and lowest condom use, occurs within marriages and steady partnerships. Such “conventional” intergenerational sex may play the pivotal role in sustaining a generalized epidemic across generations and present the most difficult challenge to prevention.
