BACKGROUND
A year after the COVID-19 pandemic started, there are still few scientific reports on COVID-19 in Africa. This study explores the clinical profiles and factors associated with COVID-19 in Cameroon.
MATERIALS AND METHODS
In this prospective cohort study, we followed patients admitted for suspicion of COVID-19 at Djoungolo Hospital between 01st April and 31st July 2020. Patients were categorised by age groups and disease severity: mild (symptomatic without clinical signs of pneumonia), moderate (with clinical signs of pneumonia without respiratory distress) and severe cases (clinical signs of pneumonia and respiratory distress not requiring invasive ventilation). Demographic information and clinical features were summarised. Multivariable analysis was performed to predict risk.
FINDINGS
A total of 313 patients were admitted during the study period; 259 were confirmed cases of COVID-19 by Polymerase Chain Reaction (PCR). Among the confirmed cases, the male group aged 40 to 49 years (13.9%) was predominant. Disease severity ranged from mild (26.2%; n = 68) to moderate (59%; n = 153) to severe (14.7%; n = 38); the case fatality rate was 1% (n = 4). Dysgusia (46%; n = 119) and hyposmia/anosmia (37.8%; n = 98) were common features of COVID-19. Nearly one-third of patients had comorbidities (29%; n = 53), of which hypertension was the most common (18.9%; n = 49). Participation in mass gatherings (Odds Ratio (OR) = 2.37; P = 0.03) and dysgusia (OR = 2.09, P = 0.02) were predictive of diagnosis of COVID-19. Age groups 60 to 69 (OR = 7.41; P = 0.0001), 50 to 59 (OR = 4.09; P = 0.03), 40 to 49 (OR = 4.54; P = 0.01), male gender (OR = 2.53; P = 0.04), diabetes (OR = 4.05; P = 0.01), HIV infection (OR = 5.57; P = 0.03), lung disease (OR = 6.29; P = 0.01), dyspnoea (OR = 3.70; P = 0.008) and fatigue (OR = 3.35; P = 0.02) significantly predicted COVID-19 severity.
CONCLUSIONS
Most COVID-19 cases in this study were benign with low fatality. Age (40–70), male gender, HIV infection, lung disease, dyspnoea and fatigue are associated with severe COVID-19. Such findings may guide public health decision-making.

Few studies have looked at consumption of Ready-to-Use-Supplementary-Foods (RUSFs) during a nutritional emergency. Here, we describe the use and acceptability of RUSF within households in four districts of the region of Maradi, Niger during large scale preventive distributions with RUSF in 2010 targeted at children 6-35months of age. Our study comprised both quantitative and qualitative components to collect detailed information and to allow in-depth interviews. We performed a cross-sectional survey in 16 villages between two monthly distributions of RUSF (October-November 2010). All households with at least one child who received RUSF were included and a total of 1842 caregivers were interviewed using a structured questionnaire. Focus groups and individual interviews of 128 caregivers were conducted in eight of the selected villages. On average, 24.7% of households reported any sharing of RUSF within the household. Sharing practices outside the household remained rare. Most of the sharing reported occurred among children under 5years of age living in the household. On average, 91% of caregivers in all districts rated the child's appreciation of the products as good or very good. Program planning may need to explicitly accounting for the sharing of products among children under 5 within household.

BACKGROUND AND OBJECTIVES
Hypothermia is a major risk factor for high neonatal mortality. In January, night-time temperatures in Kano State can drop below 20°C. We conducted a study to elucidate the incidence of neonatal hypothermia at Garan Gamawa maternal and child health (MCH) clinic in Kano City, with an aim to improve midwifery care and reduce hypothermia-related neonatal mortality.
METHODS
The data of neonates born in January 2022 were collected retrospectively in February 2022. Hypothermia was defined as “axillary temperature below 35.5°C” in accordance with MSF Essential Obstetric and Newborn Care guidelines, 2019. Statistical analysis was done using a one-sided test for binomial proportions. Qualitative data was garnered by non-participatory observation (NPO) in the delivery room and postnatal care (PNC) ward to observe the warm chain and the interactions between staff and mothers. Individual semi-structured in-depth interviews were also conducted with eight MCH staff.
RESULTS
Amongst the 206 newborns included, 55 (26.69%, Wilson confidence interval 21.13- 33.13%, p value < 0.00001) developed hypothermia. From the NPO, contributing factors to hypothermia included: absence of skin-to-skin at birth; a delay of 40 minutes between birth and baby being put to the breast for their first feed; constant draught of outside air into delivery room; absence of heating system in delivery room and PNC ward; and the need to go outside during transfer between the delivery room and PNC ward. In-depth interviews illustrated that midwives prioritised dressing the babies rather than encouraging Kangaroo Mother Care (KMC), and that the warm chain was prone to interruption during a complicated delivery and when there were multiple labouring mothers. Additionally, some midwives were not aware of the definition of neonatal hypothermia.
CONCLUSIONS
The proportion of hypothermic neonates was significant, and several contributing factors were identified. Recommendations include the installation of a door into the delivery room and appropriate heating systems in both the delivery room and PNC ward. Training of MCH staff is required to build knowledge and skills regarding the maintenance of the warm chain, and highlighting the importance of immediate skin-to-skin at birth and KMC, which have an important role in preventing hypothermia and must be encouraged.

BACKGROUND AND OBJECTIVES
Diphtheria is a vaccine preventable disease caused by toxicogenic Corynebacterium diphtheriae. Since declaration of an outbreak in Nigeria in December 2022, Kano state has been its epicentre, with 77% of the 12,581 confirmed cases nationally. In response, a Decentralised Model of Care (DMC) for delivering proximal, fast, and easily accessible curative and preventive community-based health care was introduced in Kano. Here, we describe implementation of this DMC and assess its impact in reducing mortality from diphtheria during this outbreak.
METHODS
Components of DMC:
• OPD for the triaging and management of mild cases
• Contact clinic (mobile and fixed) to improve access to preventative care for close contacts
Main packages of DMC:
• Health and Infection Prevention and Control promotion
• Chemoprophylaxis and vaccination for close contacts
• Identification and management of simple cases
• Referral of complicated cases
• Training of health workers
DMC was implemented within existing public health facilities for outpatient services, and in the community for the management of close contacts. The selection of facilities was guided by epidemiological data analysis and mapping.
Chi-square testing was used for analysing statistical significance on mortality before and after the implementation of DMC.
RESULTS
Between weeks 2 and 48 of 2023, the health facilities included in this study managed a total of 12,662 suspected diphtheria cases. From this, 1,987 cases (136 deaths; CFR 6.84%) were managed before implementation of DMC (before week 34), and 10,675 cases (611 deaths; CFR 5.72%) were managed after its implementation (from week 34 to 48). One-tailed Chi-square testing showed a statistically significant difference in mortality before and after implementation (p-value 0.02).
CONCLUSIONS
DMC may have contributed to the reduction of mortality in healthcare facilities. Upon in-depth analysis of the impact of DMC, it may be recommended for implementation in large outbreaks. Further studies, however, need to be conducted to assess the role of DMC in improving patients’ access to healthcare and reducing the burden on healthcare facilities during massive outbreaks.

BACKGROUND
Diphtheria is an infection of the upper respiratory tract characterized by the production of an extracellular toxin. Individuals with incomplete immunization or low levels of antitoxin antibodies are particularly susceptible to infection. Specific treatment relies on Diphtheria Anti-Toxin (DAT) and the disease is preventable by active immunization. Since 2019, large outbreaks have been reported in WHO African Region, but 2023 has seen an unprecedented surge in diphtheria cases in West Africa, mainly Kano State, Nigeria.
METHODS
Médecins Sans Frontières (MSF) and Epicentre have been involved in response efforts but have faced several challenges due to limited hospital capacity and a global shortage of DAT. This led to the implementation of new solutions such as home-based care, adaptation of DAT dosage and strategic allocation of DAT stocks. Preliminary descriptive analysis shows the key figures from the 2023 diphtheria outbreak and summarizes critical insights from one year of MSF intervention in Kano.
RESULTS
MSF treated around 23 thousand individuals across 14 sites in five countries. Nearly half of these patients required hospitalization, with an overall case fatality rate (CFR) of 6%. The majority of patients were under 15 years of age, and most were female.
In Kano State, Nigeria, specifically, three main centres were established at the peak of the outbreak. MSF used adaptive strategies to deal with the constraints of the response, which were phased according to the number of cases and the availability of drugs. Centralised case management was used for severe cases, while a decentralised care model, including home-based care, was used for mild and close contacts. The primary centre, which remains operational, has received approximately 9 thousand patients.
Data indicate that the prompt administration of diphtheria antitoxin (DAT) may influence patient outcomes. Furthermore, an early immunization campaign could have potentially reduced the overall mortality rate associated with the epidemic.
CONCLUSION
The surge of diphtheria in West Africa highlighted numerous challenges in combating the disease in low-resource settings, particularly concerning the availability of diphtheria antitoxin (DAT). Further analyses are required to accurately assess the impact of home-based care and DAT dosage strategies. Scaling up global DAT production and enhancing routine vaccination programs could be crucial in preventing future outbreaks.
