Occupational hazards of traditional healers: repeated unprotected blood exposures risk infectious disease transmission

Traditional healers' knowledge and infection control practices related to HIV in Bukavu City, Democratic Republic of the Congo

BACKGROUND

Patients with HIV consult traditional healers (THs). These THs can both delay care for people living with HIV (PLHIV) and transmit HIV through poor infection control practices. The main objective of this study was to evaluate knowledge and practices of THs regarding HIV in Bukavu.

METHODS

A cross-sectional study using quantitative approach was carried out among 71 THs in Bukavu City. The collected data included the following topics: personal and socio-demographic characteristics, HIV knowledge, and infection control practices. Descriptive statistics, independent-samples T-test or F-test, and multiple linear regression were used to analyze the data with a p-value < 0.05.

RESULTS

The THs' mean age was 49.2 ± 11.2 years, and the majority were aged 40 to < 60 years. Males constituted 88.7% of THs with a male-to-female ratio of 7.9. In general, 47.9% of study participants had poor knowledge about HIV/AIDS infection, 45.1% of them had fair knowledge, and only 7.0% had good knowledge. Overall, 43.7% of THs had poor infection control practices, 52.1% of THs had fair practices, and only 4.2% of participants had good practices. Results of multiple linear regression analysis revealed that none of the personal and demographic variables studied were significant predictors of their knowledge about HIV/AIDS (p > 0.05). In terms of practices, two variables were significant predictors of infection control practices: living in Ibanda and receiving training in taking care of HIV/AIDS.

CONCLUSION AND RECOMMENDATIONS

The study revealed that THs' knowledge about HIV infection was insufficient and that they had poor infection control practices. Formal standardized training on HIV infection should be organized for all THs so that they can always refer their patients to modern, reliable antiretroviral therapy (ART) clinics and reduce the risk of occupational exposure in their practices. Although PPE's assistance for THs is required in terms of protective measures, the province health authority must also oversee infection control procedures at THs' offices.

A individually randomized controlled trial comparing Healer-led vs. clinician- led training to improve personal protective equipment use among traditional healers in South Africa

Like allopathic healthcare workers, healers are also exposed to patients' blood and body fluids. A widespread practice is the traditional "injection," in which the healer performs subcutaneous incisions to rub herbs directly into the bloodied skin, resulting in 1,500 blood exposures over their lifetime. We tested the impact of healer-led PPE training, staffed by trained traditional healers who reported using PPE during each risky clinical encounter vs. healthcare worker (HCW)-led PPE training sessions. We randomized 136 healers into one of the two study arms (67 in the healer-led group, 69 in the HCW-led group) and assessed the impact of trainer on PPE skills and use over a six-month period. All healers received one in-person day of didactic and practical training followed by three sessions at the healers' home. Participants were largely female (80%), averaged 51 years old, and practiced as a healer for an average of 17 years. Almost 44% either disclosed themselves as HIV+ or received a positive HIV test result at study initiation. Healers in the HCW arm showed equivalent PPE scores as those trained by traditional healers at baseline and at seven months. Healers in both arms self-reported high levels of glove use during"injections," with no statistical difference of use by study arm. When we assessed actual gloves and razor blades disposed of each month, a similar trend emerged. No one seroconverted during the study period. The need for PPE support among traditional healers cannot be ignored. Traditional healers can be trained to effectively disseminate PPE knowledge and skills to other traditional healers. With an estimated 200,000 traditional healers in South Africa, it is imperative that all of them have access to PPE training and supplies to prevent HIV, HCV, or HBV infections.

"If it weren't for my traditional healer, I would be dead": Engaging traditional healers to support people living with HIV in rural Mozambique

Across rural sub-Saharan Africa, people living with HIV (PLHIV) commonly seek out treatment from traditional healers. We report on the clinical outcomes of a community health worker intervention adapted for traditional healers with insight into our results from qualitative interviews. We employed a pre-post intervention study design and used sequential mixed methods to assess the impact of a traditional healer support worker intervention in Zambézia province, Mozambique. After receiving a positive test result, 276 participants who were newly enrolled in HIV treatment and were interested in receiving home-based support from a traditional healer were recruited into the study. Those who enrolled from February 2016 to August 2016 received standard of care services, while those who enrolled from June 2017 to May 2018 received support from a traditional healer. We conducted interviews among healers and participants to gain insight into fidelity of study activities, barriers to support, and program improvement. Medication possession ratio at home (based on pharmacy pick-up dates) was not significantly different between pre- and post-intervention participants (0.80 in the pre-intervention group compared to 0.79 in the post-intervention group; p = 0.96). Participants reported receiving educational and psychosocial support from healers. Healers adapted their support protocol to initiate directly observed therapy among participants with poor adherence. Traditional healers can provide community-based psychosocial support, education, directly observed therapy, and disclosure assistance for PLHIV. Multiple factors may hinder patients' desire and ability to remain adherent to treatment, including poverty, confusion about medication side effects, and frustration with wait times at the health facility.

Vhavenda Herbal Remedies as Sources of Antihypertensive Drugs: Ethnobotanical and Ethnopharmacological Studies

Hypertension is a dominant risk factor for the development of cardiovascular, kidney, and eye diseases. In Africa, it increasingly leads to hospitalisation and a strain on the public health system. However, rather than modern medicine, African traditional healers are the first choice for most South Africans. Therefore, this study is aimed at gathering information on herbal remedies traditionally used for the treatment of high blood pressure in Vhavenda, South Africa, and comparing this information with reports in the literature regarding plants used to manage high blood pressure. An ethnobotanical survey was carried out in Vhembe district and its environs with 53 herbalists and indigenous people aged between 36 and 66 years from January to October 2019 using a semistructured questionnaire. The plants were collected with each respondent; they were authenticated and kept in herbarium. A total of 51 different plants were mentioned as being most commonly used for hypertension treatment. Of these, 44 plants were identified, with those from the Fabaceae family followed by plants from the Celastraceae family being commonly mentioned. Of these, the Elaeodendron transvaalense, Tabernaemontana elegans, Elephantorrhiza elephantina, and Aloe vossii were commonly cited species. According to the literature data, most of the identified plants are yet to be scientifically investigated for the treatment of hypertension, whereas only preliminary investigations have been carried out on other plants, suggesting that these preliminary investigations may have highlight promising antihypertensive activities in vitro that are indicative of their potential as antihypertensive drugs. Therefore, there is a need to scientifically investigate the antihypertensive potentials of these plants as a potential source of antihypertensive treatment and compounds.

An unrecognized key population? Traditional treatment practices associated with HIV risk among traditional healers in rural South Africa

OBJECTIVE

To understand the risk of HIV acquisition through occupational exposure among rural South African traditional healers, notably via the practice of traditional skin incisions with razors.

DESIGN

A random sample of traditional healers living in South Africa participated in a cross-sectional survey that included a rapid HIV test.

SETTING

Rural Bushbuckridge district of Mpumalanga, South Africa.

PARTICIPANTS

Traditional healers.

INTERVENTION

Pretest counseling, posttest counseling, and referral to care if HIV seropositive.

MAIN OUTCOME MEASURE(S)

HIV infection.

RESULTS

Among healers who reported a previous positive test result or accepted an HIV test (96%), HIV prevalence was 30% (95% confidence interval: 23-37%). During their careers, 98% of healers reported conducting at least one 'vaccination' (as traditional incisions are called), 32% reported always using gloves when conducting these procedures, 29 (14%) reported patient blood touching their bare skin. Healers who reported exposure to patient blood had a higher HIV prevalence than their nonexposed colleagues (adjusted risk ratio: 2.35, 95% confidence interval: 1.55-3.56, P = 0.001).

CONCLUSION

Nearly all traditional healers are routinely performing minimally invasive skin incisions that could expose them to patient blood. The lack of training and access to personal protective equipment increase their risk of acquisition of blood-borne pathogens, including HIV. Given the widespread practice of traditional skin incisions across southern Africa, and the higher levels of HIV among traditional healers exposed to patient blood, it is likely that traditional healers are a hitherto unrecognized key population at disproportionate risk of acquiring HIV.

Underestimation of hepatocellular carcinoma incidence resulting from a competition between modern and traditional medicine: the case of Gabon

Primary liver cancer, particularly hepatocellular carcinoma (HCC), remains a major killer in sub-Saharan Africa. In this dreadful landscape, West and Central Africas are more particularly affected. However, a small country located on the equator, Gabon, is apparently not concerned by this adverse situation. Despite worrying prevalences of many bona fide risk factors of HCC, including high rates of chronic infections with hepatitis viruses and very high alcohol consumption, Gabon presents theoretically an amazingly low incidence of HCC when compared to other countries of the region. Reports from many places in the world have emphasized the widespread underreporting of HCC cases presumably attributable to the difficulties of proper diagnosis or to a lack of local cancer registry. In Gabon, the remarkably vivid tradition of religious initiation called Bwiti includes some therapeutic rituals exerted by healers or Ngangas. Those treatments are particularly popular in case of severe diseases generally associated with a supernatural etiology. In the present paper, we hypothesize that, in Gabon, the remarkably low incidence of HCC is primarily due to the diversion of patients from the modern medical system due to their preference for Ngangas. Promotion of a form of medical syncretism respecting both systems might be an efficient policy to increase the attractiveness of modern medicine and to ultimately promote public health in Gabon.

Traditional healers use of personal protective equipment: a qualitative study in rural South Africa

BACKGROUND

Traditional healers are frequently exposed to hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) through the widespread practice of traditional "injections", in which the healer performs dozens of subcutaneous incisions using a razor blade to rub herbs directly into bloodied tissue. An average healer in Agincourt, a rural northeastern sub-district in Mpumalanga province, South Africa, experiences approximately 1500 occupational blood exposures over the course of their lifetime. Healers in Agincourt have an HIV prevalence of 30% compared to 19% in the general population, and healers who report exposure to patient blood have an adjusted 2.4-fold higher odds of being HIV-positive than those with no exposure. Although research on appropriate PPE use has been well documented for allopathic care providers, little is known about the practices of traditional healers.

METHODS

This qualitative study was conducted with 30 traditional healers who practice in the rural Bushbuckridge sub-district of Mpumalanga province, northeastern South Africa. We elicited traditional healer attitudes towards glove use during traditional treatments - including patient baths, injections, or other treatments that exposed healers to patient blood or open sores.

RESULTS

While 90% of healers reported using latex gloves during some treatments, the majority do not use them regularly. Most employ a combination of gloves, plastic shopping bags, bread bags, paper, and sticks to prevent blood exposure. Healers reported plastic bags slipping or breaking during procedures, exposing them to patient blood. Only three healers consistently used gloves, regardless of the cost.

CONCLUSIONS

Inadequate PPE use and high HIV prevalence make traditional healers particularly susceptible to contracting HIV in rural South Africa. Despite positive attitudes, consistent glove use remains low due to financial constraints and glove availability. Addressing issues of accessibility and cost of gloves for traditional healers could have a significant impact on the adherence to PPE and, in turn, reduce new HIV infections among this high-risk group.

Traditional healer treatment of HIV persists in the era of ART: a mixed methods study from rural South Africa

BACKGROUND

Human immunodeficiency virus (HIV) substantially contributes to the burden of disease and health care provision in sub-Saharan Africa, where traditional healers play a major role in care, due to both their accessibility and acceptability. In rural, northeastern South Africa, people living with HIV often ping-pong between traditional healers and allopathic providers.

METHODS

We conducted 27 in-depth interviews and 133 surveys with a random sample of traditional healers living in Bushbuckridge, South Africa, where anti-retroviral therapy (ART) is publicly available, to learn: (1) healer perspectives about which HIV patients they choose to treat; (2) the type of treatment offered; (3) outcomes expected, and; (4) the cost of delivering treatment.

RESULTS

Healers were mostly female (77%), older (median: 58.0 years; interquartile range [IQR]: 50-67), with low levels of formal education (median: 3.7 years; IQR: 3.2-4.2). Thirty-nine healers (30%) reported being able to cure HIV in an adult patients whose (CD4) count was >350cells/mm³. If an HIV-infected patient preferred traditional treatment, healers differentiated two categories of known HIV-infected patients, CD4+ cell counts <350 or ≥350 cells/mm³. Patients with low CD4 counts were routinely referred back to the health facility. Healers who reported offering/performing a traditional cure for HIV had practiced for less time (mean = 16.9 vs. 22.8 years; p = 0.03), treated more patients (mean 8.7 vs. 4.8 per month; p = 0.03), and had lower levels of education (mean = 2.8 vs. 4.1 years; p = 0.017) when compared to healers who reported not treating HIV-infected patients. Healers charged a median of 92 USD to treat patients with HIV.

CONCLUSION

Traditional healers referred suspected HIV-infected patients to standard allopathic care, yet continued to treat HIV-infected patients with higher CD4 counts. A greater emphasis on patient education and healer engagement is warranted.
