The COVID-19 infection has been a matter of urgency to tackle around the world today, there exist 200 countries around the world and 54 countries in Africa that the COVID-19 infection cases have been confirmed. This situation prompted us to look into the challenges African laboratories are facing in the diagnosis of novel COVID-19 infection. A limited supply of essential laboratory equipment and test kits are some of the challenges faced in combatting the novel virus in Africa. Also, there is inadequate skilled personnel, which might pose a significant danger in case there is a surge in COVID-19 infection cases. The choice of diagnostic method in Africa is limited as there are only two available diagnostic methods being used out of the six methods used globally, thereby reducing the opportunity of supplementary diagnosis, which will further lead to inappropriate diagnosis and affect the accuracy of diagnostic reports. Furthermore, challenges like inadequate power supply, the method used in sample collection, storage and transportation of specimens are also significant as they also pose their respective implication. From the observations, there is an urgent need for more investment into the laboratories for proper, timely, and accurate diagnosis of COVID-19.

Zoonotic diseases occur as a result of human interactions with animals with the inadvertent transmission of pathogens from one to another. Zoonoses remain a major cause of morbidity and mortality among human populations, as they have been a source of pandemics in human history. Viral zoonoses account for a significant percentage of pathogens of zoonotic sources, posing a huge risk to men’s general health and fertility. This review identifies the existing knowledge on the effects of viral zoonotic diseases on male fertility. Evidence from reviewed articles showed that viral zoonotic diseases elicit an immune reaction that induces inflammatory mediators and impairs testicular functions such as spermatogenesis and steroidogenesis, leading to abnormal semen parameters that lead to subfertility/infertility. Although most zoonotic viruses linger in semen long after recovery, their presence in semen does not directly translate to sexual transmission. There is a need to further delineate the possible risk of the sexual transmission of these diseases. While a few of the viral zoonotic diseases discussed have been well-studied, there is a need to place attention on others so as to fully understand their effects on male reproduction and therefore take the right steps towards preserving male fertility.

Bacterial zoonotic diseases hold significant public health importance due to their substantial contribution to human morbidity and mortality. These infections have been implicated in reducing the fertility rate among couples of reproductive age. Despite the increasing prevalence of infertility and sub-fertility in men, there has been limited investigation into the possible effects of bacterial zoonotic infections on the male reproductive system. The purpose of this review is to describe common bacterial zoonotic diseases and their effects on human reproduction in order to unveil the hidden roles these infections could play in male factor infertility. While there is a dearth of information on this subject from human studies, available evidence from experimental animals suggests that bacterial zoonotic diseases impair male reproductive functions and structures primarily through the activation of the inflammatory response and distortion of the antioxidant system, resulting in the generation of oxidative species. In light of the limited research on bacterial zoonotic diseases and their role in male reproduction, efforts must be directed towards the subject to unravel the underlying pathological mechanisms and reduce the incidence among the human populace, either through preventive or curative measures.
