· Biostatics- Biostatisticians dabble in a fair amount of statistics and further analysis to draw linkages in public health problems. They devise strategic models, predict trends, observe changes minutely and calibrate risk factors. Considering the number-crunching required, deep insights as a trait, industry faces a dearth of sound biostatisticians.

· Epidemiology: A sought after field, it is the converging ground for biostatistics, community health and socio-cultural aspects including the economics of public health. Epidemiologists work tirelessly to find the causative factors, the spread of disease and aim to find solutions.

· Environmental Health: It is a fast-emerging field due to the rise in environment-related health issues. Environmental scientists, Quality investigators and Environmental engineers are some of the diverse profiles a student of environmental health can assume. They work in identifying areas that are critical to human health like water, air and pollution factors, to name a few.

· Policy and Management: These committed individuals are drawn from various disciplines and are adept in matters of finance, management, economics, law, ethics and more. Holding considerable sway over public health policy design and formulation, their expertise and insight are much needed by the industry and governmental agencies alike. Public Health Management is fast coming up as a lucrative career option in recent times.

· Maternal and Child Health: Aimed at protecting expecting women, mothers and children throughout the reproductive cycle and beyond, this area is very important, as a majority of the population consists of young women and children. These healthcare professionals deal in pre or post-natal care, infant care, and mortality rates. In many sub-Saharan countries, especially the developing ones, the role of a qualified individual from this field is very important.

Current Public Health Scenario in Africa

Africa has long remained one of the most neglected places on earth and is home to a number of life-threatening epidemics, diseases, and pestilences. It has for centuries suffered the worst outbreak of deadly diseases accentuated by a crippling economy and devastating inter-regional disputes and ethnic conflicts. The World Health Organization (WHO) has done a remarkable job in drawing the attention of the world to the state of Public Health in Africa. There are several key points that are absolutely essential when discussing the health situation on the African continent. By 2050, nearly 60% of the population of the continent is expected to be living in urban areas and 35– 40% of children and adolescents globally are projected to be living in Africa. With nearly 1.22 billion inhabitants, almost 60% of the population is struggling with HIV/AIDS. One of the leading causes of death, the tide has been stemmed thanks to anti-retroviral medication. 90% of all worldwide reported malaria deaths occur in Africa, while records of leprosy incidences have shown a remarkable decline.

With high mortality rates, special under five, focus on child health in recent times has shown positive outcomes. Polio is nearing eradication and aggressive immunization programs have caught up to tackle other threats like measles. Still, African nations feature high on the list of countries with high rates of newborn and maternal mortality. Modern-day Non-Communicable Diseases (NCD) like diabetes, cancer, coronary ailments continue to pose challenges. This is augmented by poor sanitation, lack of clean water and resources, the dearth of qualified medical professionals. With SGD goals aimed at elevating public health, much remains to be done with regard to Public Health in Africa and Public Health Management.

Mapping Africa’s Advanced Public Health Education Capacity

Given the humungous nature of health problems grappling Africa in general and Sub-Saharan regions in particular, some key findings as per the latest research, present a telling picture of Public Health in Africa. A 2015 report suggests that Africa had one doctor for every 5000 people with most of the full-time staff being male. More than 50% of the African countries do not offer postgraduate training in public health program with a little more than 20% offering a single program while only 20% offer more than one program in public health. This speaks volumes about the urgent need to expand the continent’s focus on public health. There is a marked disconnect between public health education and research, calling for the greater need for holistic expansion. Provisions for studying public health online will enable many students to pursue a career in public health as many parts of Africa is geographically disconnected. Public health courses need to ramp up as Africa needs more graduates who opt for a career in public health to fill the gap.
