ABSTRACT
BackgroundThe World Health Organization has warned against a dramatic impact of COVID-19 in sub-Saharan Africa unless adequate response strategies are implemented. Whatever the strategy, the role of health care workers is pivotal. We undertook this study to assess knowledge of COVID-19 and perception of the response to the pandemic among the staff of a regional hospital in charge of COVID-19 patients in West Cameroon. MethodsWe used a convenience non probabilistic sampling method to carry out a survey with a self-administered questionnaire from April 14, 2020 to April 29, 2020 at the Bafoussam Regional Hospital (BRH). All the staff was invited to participate. Statistical analyses were done using Microsoft Excel 2010 and Epi-lnfo version 7.1.5.2 software. ResultsResponse rate was 76.1% (464/610). Mean age (SD) and average work experience (SD) were 35.0 (8.9) and 8.4 (7.4) years respectively. Sex ratio (M/F) was 101/356. Nursing and midwifery staff (56.8%) and in-patients units (49.94%) were predominant. Knowledge on origin and transmission of SARS-CoV-2 was poor but knowledge of clinical signs and the role of laboratory tests were good. 53.2% of respondents said all therapeutic regimens are only supportive and only a third of them trusted drugs recommended by health authorities. For 36.9% of respondents, herbal remedies can prevent/cure COVID-19. 70% of staffs felt they were not knowledgeable enough to handle COVID-19 cases. 85.6% of respondents thought the BRH had insufficient resources to adequately respond to COVID-19 and 55.6% were dissatisfied with its response to the pandemic (weaknesses: medicines/technologies (74.5%), service delivery (28.1%), human resource (10.9%)). 68% of staff felt insufficiently protected on duty and 76.5% reported that the pandemic significantly reduced non-COVID-19 services. 85.5% said they complied with preventive measures while in the community. For 44% of respondents Cameroonian regulations on COVID-19 corpses should be made more culture-sensitive. 51.2% of respondents were against vaccine trial in their community. ConclusionKnowledge of COVID-19 was poor and perception of the response to the pandemic was unfavorable.
ABSTRACT
Eleven plants used in the Cameroonian traditional medicine for the treatment of some parasitic infections were tested for their activity on the promastigote form of Leishmania donovani. After incubation with different plant extracts at doses of 1600, 800, 400 and 200 microgram/mL, the evaluation of the cell viability was done by the trypan blue exclusion technique and by flow cytometry. This study shows that 48 h after incubation of promastigotes with plant extract, Solanocia mannii and Solanum torvum significantly inhibited the proliferation of promastigotes in culture with IC50 of 60.78±5.05 and 96.08±4.39 using the trypan blue exclusion technique. In addition, IC50 of 43.91±6.49 and 86.13±4.30 were obtained using the flow cytometry technique. Furthermore, 24 h after incubation of promastigotes with the Solanocia mannii and Solanum torvum, there was significant disruption of their long spindle shaped bodies. The results of this study support the popular uses of these plants for the treatment of some parasitic infections in Cameroonian folk medicine.
