Recent forecasts by the Food and Agriculture Organization of the United Nations (FAO) have indicated a risk of locust invasion in West Africa from June 2020. From East Africa, some swarms could reac...h the eastern part of the Sahel and continue westwards from Chad to Mauritania.
Surveillance and control teams will be mobilized across the region with a focus on Burkina Faso, Chad, Mali, Mauritania, and the Niger, and extended to Senegal. Countries such as Cameroon, the Gambia and Nigeria are also on watch in the event that desert locust spreads to these highly acute food-insecure countries. Since the region could be threatened in the coming months, FAO is strongly encouraging no regret investments in preparedness and anticipatory action to control swarms and safeguard livelihoods, given already high levels of acute food insecurity. Therefore, cost estimates for preparedness, anticipatory action and rapid response have been assessed.

In 2015, the United Nations set important targets to reduce premature
cardiovascular disease (CVD) deaths by 33% by 2030. Africa disproportionately
bears the brunt of CVD burden and has one of the highest risks of dying
from non-communicable dise...ases (NCDs) worldwide. There is currently
an epidemiological transition on the continent, where NCDs is projected
to outpace communicable diseases within the current decade. Unchecked
increases in CVD risk factors have contributed to the growing burden of three
major CVDs—hypertension, cardiomyopathies, and atherosclerotic diseasesleading to devastating rates of stroke and heart failure. The highest age
standardized disability-adjusted life years (DALYs) due to hypertensive heart
disease (HHD) were recorded in Africa. The contributory causes of heart failure
are changing—whilst HHD and cardiomyopathies still dominate, ischemic
heart disease is rapidly becoming a significant contributor, whilst rheumatic
heart disease (RHD) has shown a gradual decline. In a continent where health
systems are traditionally geared toward addressing communicable diseases,
several gaps exist to adequately meet the growing demand imposed by CVDs.
Among these, high-quality research to inform interventions, underfunded
health systems with high out-of-pocket costs, limited accessibility and
affordability of essential medicines, CVD preventive services, and skill
shortages. Overall, the African continent progress toward a third reduction
in premature mortality come 2030 is lagging behind. More can be done in
the arena of effective policy implementation for risk factor reduction and
CVD prevention, increasing health financing and focusing on strengthening
primary health care services for prevention and treatment of CVDs, whilst
ensuring availability and affordability of quality medicines. Further, investing
in systematic country data collection and research outputs will improve the accuracy of the burden of disease data and inform policy adoption on
interventions. This review summarizes the current CVD burden, important
gaps in cardiovascular medicine in Africa, and further highlights priority
areas where efforts could be intensified in the next decade with potential
to improve the current rate of progress toward achieving a 33% reduction
in CVD mortality.

Non-communicable diseases (NCDs) are the second common cause of death in sub-Saharan Africa (SSA) accounting for about 35% of all deaths, after a composite of communicable, maternal, neonatal, and nutritional diseases. Despite prior perception of lo...w NCDs mortality rates, current evidence suggests that SSA is now at the dawn of the epidemiological transition with contemporary double burden of disease from NCDs and communicable diseases. In SSA, cardiovascular diseases (CVDs) are the most frequent causes of NCDs deaths, responsible for approximately 13% of all deaths and 37% of all NCDs deaths. Although ischemic heart disease (IHD) has been identified as the leading cause of CVDs mortality in SSA followed by stroke and hypertensive heart disease from statistical models, real field data suggest IHD rates are still relatively low. The neglected endemic CVDs of SSA such as endomyocardial fibrosis and rheumatic heart disease as well as congenital heart diseases remain unconquered. While the underlying aetiology of heart failure among adults in high-income countries (HIC) is IHD, in SSA the leading causes are hypertensive heart disease, cardiomyopathy, rheumatic heart disease, and congenital heart diseases. Of concern is the tendency of CVDs to occur at younger ages in SSA populations, approximately two decades earlier compared to HIC. Obstacles hampering primary and secondary prevention of CVDs in SSA include insufficient health care systems and infrastructure, scarcity of cardiac professionals, skewed budget allocation and disproportionate prioritization away from NCDs, high cost of cardiac treatments and interventions coupled with rarity of health insurance systems. This review gives an overview of the descriptive epidemiology of CVDs in SSA, while contrasting with the HIC and highlighting impediments to their management and making recommendations.

The article "Barriers and determinants of asthma control in children and adolescents in Africa: a systematic review" analyzes factors contributing to poor asthma control in African youth. Based on studies conducted between 2014 and 2019 in Nigeria, ...Uganda, and South Africa, the review identifies key challenges such as limited access to asthma diagnosis, inadequate use of inhaled corticosteroids, and environmental and socio-economic factors. It finds that urban living, older age, and concurrent allergic conditions significantly affect asthma management. The study emphasizes the need for improved diagnostic tools, better access to treatment, and tailored public health interventions to enhance asthma outcomes in African children.

Asthma is the most common non-communicable disease in children and remains one of the most common throughout the life course. The great majority of the burden of this disease is seen in low-income and middle-income countries (LMICs), which have disproportionately high asthma-related mortality relati...ve to asthma prevalence. This is particularly true for many countries in sub-Saharan Africa. Although inhaled asthma treatments (particularly those containing inhaled corticosteroids) markedly reduce asthma morbidity and mortality, a substantial proportion of the children, adolescents, and adults with asthma in LMICs do not get to benefit from these, due to poor availability and affordability. In this review, we consider the reality faced by clinicians managing asthma in the primary and secondary care in sub-Saharan Africa and suggest how we might go about making diagnosis and treatment decisions in a range of resource-constrained scenarios. We also provide recommendations for research and policy, to help bridge the gap between current practice in sub-Saharan Africa and Global Initiative for Asthma (GINA) recommended diagnostic processes and treatment for children, adolescents, and adults with asthma.

Background: COVID-19 is a global public health crisis that affects all sectors; studying the impact of this pandemic on the delivery of cardiology services in Africa is crucial as COVID-19-related cardiovascular complications may worsen the CVD burd...en in this already highly affected and resource-limited continent
Methods: This was a cross-sectional e-survey study conducted amongst cardiologists in African countries. The primary outcome was the change in service delivery in African cardiology units during the on-going COVID-19 pandemic. The secondary outcomes were the satisfaction of cardiologists with regards to the workload and factors associated with this satisfaction.
Results: There was a significant reduction in working time and the number of patients consulted by week during this pandemic (p<0.001). In general, there was a decrease in the overall activities in cardiovascular care delivery. The majority of cardiology services (76.5%) and consulting programs (85%) were adjusted to the pandemic. Only half of the participants were satisfied with their workload. Reconfiguration of the consultation schedule was associated with a reduced satisfaction of participants (p=0.02).
Conclusions: COVID-19 is associated with an overall reduction in cardiology services rendered in Africa. Since the cardiovascular burdens continue to increase in this part of the World and the risk of cardiovascular complications linked to SARS COV2 remains unchanged cardiology, departments in Africa should anticipate a significant surge of cardiology services demanded by patients after the COVID-19 pandemic.
