Abstract:
As the COVID-19 pandemic sweeps the globe, causing tens of thousands of deaths in most Western countries with economies round the world in turmoil, Africa has so far been largely spared the kind of impact that has thrown the United States, South America and Europe into crisis. Most African countries remain seriously unprepared to handle the pandemic of the nature the Western world is dealing with; Africa, from Mali to Ethiopia to Libya and down to South Africa, have insufficient ventilators or intensive care beds to cope with COVID-19 should it strike with ferocity as it is doing in the Western world. As COVID-19 reaches the shores of Africa, despite poor health facilities, poor living conditions and inadequate availability of clean water across the continent, Africans are still putting up a fight taking COVID-19 head on with use of cheap technology, and help from the continent’s protective climate. However, Africa cannot afford to be complacent. African countries must continue to adopt strict social distancing measures, educate their people on the importance of intake of regular vitamin D, good exercising habit, good sleep pattern, adequate hand hygiene measures, as well as strictly enforcing the “test, trace and isolate“ model to the letter for the continent to take on the fight head on and wage a proper war against COVID-19.

Abstract:

Salmonella Kentucky is ubiquitous in most African countries and the multidrug resistant (MDR) strains remain underreported across the continent. In Nigeria, poverty, inter country livestock trades, nomadic system of cattle production, indiscriminate use of antibiotics and prevalent immuno-compromising diseases such as human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and tuberculosis are factors that have enabled ease of transmission and complications of S. Kentucky infections. In the present decade, S. Kentucky is reported to be the most prevalent serovar associated with poultry in Nigeria, but very few reports underline the risk associated with consumption of poultry and acquisition of MDR S. Kentucky strains. The Nigerian poultry is one of the most commercialized subsectors of Nigerian agriculture, therefore, the presence of S. Kentucky especially strains carrying broad spectrum antimicrobial resistance pose a great risk to public health. The lack of proper monitoring, surveillance, isolation and control of the multidrug resistant S. Kentucky will remain a challenge to the export potential of the Nigerian poultry subsector and livestock in general. As a nation, modalities and actions against the smuggling of poultry products, indiscriminate use of antibiotics and nomadic system for the production of dairy and beef that promotes spread of virulent strains of Salmonellae must change. The impact of non-typhoidal salmonellosis in humans in Nigeria also remains under studied and under reported, especially those caused by S. Kentucky ST198. Compounding these concerns is the lack of commercial veterinary or human vaccines against S. Kentucky or where vaccines against the broad serogroup C non-typhoidal Salmonella (NTS) are available, they are rarely supplied, with no evidence they could be cross-protective. This review emphasizes the emergence and widespread occurrence of MDR S. Kentucky strains on the African continent, and discussed risk factors contributing to its spread in Nigeria and the potential public health challenge especially to high-risk immunocompromised individuals.

Review Article: Epidemiology of Malaria in Africa

TM Akande, IO Musa

 

Abstract

Malaria is a life threatening parasitic disease transmitted by female anopheles mosquitoes. There are four types of human parasites; Plasmodium vivax, P. malariae, P ovale and P. falciparum. P. falciparum and P. vivax are the most common and P. falciparum, the most deadly type of infection, is most common in sub-Saharan Africa. A large number of environmental factors affect the distribution, seasonality and transmission intensity of malaria. Rainfall provides breeding sites for mosquitoes and increases the humidity, which enhances their survival. While malaria is largely endemic in Africa, varying proportion of countries in the continent are at risk of endemic malaria. Today, approximately 40% of the world population, mostly those living in the world’s poorest countries, is at risk of malaria. This is mostly in the tropical and sub-tropical regions of the world. There are at least 300 million acute cases of malaria each year globally resulting in more than a million deaths, around 90% of these occur in Africa, mostly young children. In areas of stable malaria transmission, very young children and pregnant women are the population at highest risk for malaria morbidity and mortality. The populations most at risk of epidemics are those living in highlands, arid and desert-fringe zones and those living in areas where successful control measures have not been consolidated or maintained.
Key words: Epidemiology, Malaria, Africa
