Globally, health providers and patients alike have been forced to adapt rapidly to the use of telemedicine during the COVID-19 pandemic. Although telepsychiatry has been tested and found just as effective as face-to-face care, there still remains little uptake of this form of care provision in sub-Saharan Africa. This case study highlights the use of telepsychiatry in a previously telemedicine-naive private mental health facility in Kenya.

Background: COVID-19-related restrictions on in-person contact in healthcare, increasing psychiatric illness during the pandemic and pre-existing shortages of mental healthcare providers have led to the emergence of telepsychiatry as an attractive option for the delivery of care. Telepsychiatry has been promoted as economical and effective, but its acceptance in low- and middle-income countries is poorly understood.

Aims: To explore the acceptance, experiences and perspectives of patients and healthcare providers in the uptake of telepsychiatry services in a middle-income country.

The use of social media to increase awareness on mental health is rapidly gaining momentum globally. However, despite evidence of a growing trend in social media use in sub Saharan Africa, little has been reported on tapping the potential of social media within a mental health practice to not only increase awareness but also facilitate linkage to specialist care. We describe one such mental health practice and its process of integration of the different social media platforms to promote mental health and increase linkage to specialist care.

A study was undertaken to investigate and mitigate the risk from zoonotic Cryptosporidium associated with dairy farming in Dagoretti division, Nairobi, Kenya. Outcome mapping (OM), a relatively new tool for planning and evaluation, was used to foster and then monitor changes in farmer management of health risks. Elements of the OM framework, including the vision, mission and expected progress markers, were developed in participatory sessions and a set of progress markers was used for monitoring behaviour change in farmers participating in the project (the boundary partners).

In a case-control study based in two areas of Kenya, hepatosplenic schistosomiasis mansoni was shown to be linked with low levels of IL-5 and with correspondingly high IFN-gamma, TNF, and circulating soluble TNF receptor I (sTNFR-I), sTNFR-II, and sICAM-1. PBMC from the hepatosplenic cases responded to in vitro Ag stimulation with significantly higher levels of IFN-gamma and TNF, but lower levels of IL-5, compared with nonhepatosplenic controls matched for age and infection intensity. Most of these correlations were confounded by differences between geographical areas.
