South Africa – Health Issues

What are the most common health issues and diseases in South Africa?

Health researchers use the term “dual burden” to describe South Africa’s disease landscape — a situation in which the country simultaneously shoulders a heavy load of infectious illness and an accelerating rise in non-communicable diseases (NCDs). Among communicable diseases, malaria, tuberculosis (TB), and HIV/AIDS are the most prominent. Alongside these, changing lifestyles driven by urbanisation — less physical activity, poorer dietary choices, tobacco use, and increasing obesity — have fuelled surging rates of cardiovascular disease, cancer, diabetes, and chronic respiratory conditions.

Tuberculosis represents one of South Africa’s most pressing public health challenges, with roughly 450,000 new cases diagnosed annually. Of these, approximately 270,000 individuals are co-infected with HIV. TB holds the grim distinction of being the single leading cause of death in the country, claiming around 89,000 lives every year — a burden that stands in stark contrast to high-income nations, where TB has been largely eradicated from daily life.

An estimated 8.45 million people in South Africa are living with HIV, cementing it as one of the country’s most defining health crises. Because a weakened immune system allows latent TB infection to become active, HIV is a significant driver of TB’s continued prevalence. Treatment landscapes have improved dramatically, however: effective antiretroviral therapy can suppress the virus to undetectable levels, dramatically reducing the risk of opportunistic infections and enabling people living with HIV to lead full and healthy lives.

South Africa registers high international rates of HIV, hypertension, diabetes, and arthritis, and these conditions are reflected in the most commonly encountered chronic disease combinations across the population. By 2019, hypertension had become the most widespread chronic condition in the country, with 4.74 million South Africans affected. More than one in three adults lives with high blood pressure; because the condition rarely produces obvious symptoms, the majority of sufferers remain undiagnosed.

Complications arising from diabetes rank as the second leading cause of death in South Africa. Approximately 4.5 million people in the country are estimated to have diabetes, giving South Africa the highest number of adult diabetics on the African continent. Geographic disparities in disease burden are also notable: KwaZulu-Natal records the highest provincial TB rate in the country, exceeding 700 cases per 100,000 people.

Is South Africa considered a healthy country? How do health outcomes compare internationally?

South Africa’s life expectancy stands at roughly 66.5 years, compared with a global average of 73.7 years according to United Nations data. To contextualise this further, the worldwide average in 2023 was 70.8 years for men and 76.0 years for women, with sharp regional disparities ranging from 57.7 years in Western Africa to 82.7 years in Western Europe. South Africa lags well behind the averages seen in developed nations, though it has made meaningful progress since the HIV epidemic reached its most destructive peak in the early 2000s.

Southern African nations most heavily affected by HIV — including South Africa — are only now beginning to see life expectancy return toward levels recorded before the epidemic took hold. This recovery is attributable principally to the large-scale rollout of antiretroviral programmes and enhanced infectious disease management. Nevertheless, gains made against communicable diseases have been partially countered by the mounting toll of hypertension, diabetes, and other non-communicable conditions.

Non-communicable diseases are now responsible for more than 30% of disability-adjusted life years in South Africa — a metric that accounts for both premature death and years lived with illness or disability. This represents a substantial and expanding share of the overall disease burden. The Human Rights Measurement Initiative assesses that South Africa is achieving 73.4% of the health outcomes that would be expected given its income level, indicating that health results fall short of what the country’s economic capacity should theoretically deliver.

For the most current data on South Africa’s health indicators, readers are encouraged to consult the WHO South Africa country profile and Statistics South Africa, both of which are updated on a regular basis.

What infectious diseases or environmental health risks should expats be aware of?

Although much of South Africa — particularly its large cities — presents a relatively recognisable health environment, certain infectious and environmental hazards require targeted preparation, especially for those relocating from regions where such risks are uncommon.

Malaria is among the most significant vector-borne threats to consider. Plasmodium falciparum malaria occurs in the Mopani and Vhembe Districts of Limpopo Province along the borders with Zimbabwe and Mozambique, in the Ehlanzeni District of Mpumalanga, and in the uMkhanyakude District of KwaZulu-Natal Province. Kruger National Park, which straddles two of these provinces, is considered malaria-endemic with seasonal transmission patterns. The South African National Department of Health advises travellers to practise mosquito avoidance throughout the year in malaria risk areas and to take malaria chemoprophylaxis between September and May; the CDC, however, recommends chemoprophylaxis year-round. Expats who will be living in or frequently visiting these regions should seek personalised advice from a travel health specialist before moving.

African tick-bite fever is another condition deserving attention. It is widespread in South Africa, and those camping, hiking, or spending time in rural bush environments are at heightened risk. Since this disease is seldom encountered in many temperate countries, expats venturing into the bush should wear clothing that covers exposed skin and apply appropriate insect repellent as preventive measures.

Yellow fever does not occur within South Africa’s borders. However, South Africa requires a valid International Certificate of Vaccination or Prophylaxis (ICVP) confirming yellow fever vaccination administered at least 10 days prior to arrival for all travellers aged one year and over who are arriving from, or transiting for more than 12 hours through the airport of, a country where yellow fever virus transmission is a risk. Anyone travelling via a yellow fever-endemic country must carry documented proof of vaccination.

Other infectious diseases of note in South Africa include bacterial diarrhoea, typhoid fever, and hepatitis A. Water sanitation is generally reliable in large urban centres, but those venturing into rural regions should exercise caution. The CDC Yellow Book for South Africa advises expats to confirm that routine immunisations — including measles-mumps-rubella (MMR), diphtheria-tetanus-pertussis, and influenza — are current, and to consider hepatitis A and typhoid vaccines if exposure through food or water is likely. Current vaccination recommendations should always be verified with your home country’s travel health authority or a registered travel medicine clinic before departing.

Expats should also familiarise themselves with the risk of schistosomiasis, a parasitic infection transmitted through freshwater. The condition is endemic across large portions of the country. Swimming or wading in freshwater lakes, rivers, and streams in affected areas should be avoided. The National Institute for Communicable Diseases (NICD) serves as South Africa’s principal body for infectious disease surveillance, issuing regular alerts and clinical guidance.

Is smoking common in South Africa, and what are the laws around it?

South Africa has taken a comparatively progressive stance on tobacco control relative to many of its regional neighbours. The Tobacco Products Control Act, enacted in the late 1990s and strengthened through subsequent amendments, introduced restrictions on smoking in enclosed public spaces, bans on tobacco advertising, and mandatory health warnings on cigarette packaging. More recent legislative efforts have sought to tighten these provisions even further.

Tobacco use is identified as one of the key behavioural drivers behind the surge in non-communicable diseases in South Africa, alongside physical inactivity and unhealthy eating. Studies indicate that curtailing tobacco and alcohol consumption, combined with improved nutrition, could produce a meaningful reduction in the country’s NCD burden.

In practical terms, smoking is prohibited in most enclosed public spaces across the country, including workplaces, restaurants, bars, shopping malls, and public transport. South Africa’s approach broadly mirrors that of countries such as Australia and the United Kingdom, where indoor smoking bans in hospitality settings have long been in force, though the rigour of enforcement can vary. Designated outdoor smoking areas are a common feature at larger venues. Vaping and e-cigarettes are increasingly brought under the same regulatory umbrella, and the legislative direction has been toward tighter controls. Expats accustomed to strictly enforced smoke-free environments will generally find South Africa’s major cities in keeping with those standards, though compliance in rural and informal settings may be less consistent. The South African National Department of Health website carries the latest updates on tobacco legislation.

Is obesity or poor diet a significant health concern in South Africa?

Obesity is a serious and worsening public health problem in South Africa. In 2016, 31% of adult men, 67% of adult women, and 13% of children under five were classified as either overweight or obese. More recent figures confirm the trajectory has not reversed: according to WHO data, 30.8% of the adult population was living with obesity in 2022.

These statistics place South Africa among the most severely affected countries in sub-Saharan Africa and compare unfavourably with many higher-income nations. The health consequences are wide-ranging: national survey analysis found that 87% of Type 2 diabetes cases, 68% of hypertension cases, 61% of endometrial cancer cases, 45% of ischaemic stroke cases, and 38% of ischaemic heart disease cases could be attributed to an elevated body mass index.

Research indicates that the body mass index of 41% of women and 11% of men in South Africa exceeds 30 kg/m², pointing to levels of physical inactivity that are likely too high across the population, alongside concerns about dietary quality. Urban diets tend to be heavy in processed foods, refined carbohydrates, salt, and sugar, while consumption of fruits and vegetables frequently falls short of recommended guidelines.

The South African government has acknowledged the severity of this challenge. The National Department of Health released a Strategy for the Prevention and Management of Obesity in South Africa spanning 2023 to 2028, which outlines objectives relating to healthy food promotion, physical activity, and early-stage intervention. South Africa has also introduced a Health Promotion Levy — a tax on sugar-sweetened beverages — as part of broader efforts to reshape dietary patterns. Expats would be well advised to remain conscious of local food culture and to make deliberate choices about nutrition and exercise, particularly if relocating from countries with mature public health nutrition frameworks.

What are the mental health attitudes and services like in South Africa?

Mental health in South Africa is shaped by an intricate web of factors: the enduring psychological legacy of historical trauma, deep socioeconomic inequality, high exposure to violence, and a substantial burden of chronic physical illness. While HIV and tuberculosis have historically dominated health screening efforts, there is a growing recognition of the need to screen for mental health conditions alongside NCDs.

Mental illness — including PTSD — is markedly more prevalent among individuals who have experienced traumatic events, and substance misuse represents another major contributor to poor mental health across the country. The prevalence of mental illness among people living with HIV reaches 43.7%, compared to 16.5% in the general population. Social stigma continues to deter many from seeking help, and public awareness campaigns remain limited in their reach.

Public mental health services exist within the national health system but are significantly underfunded — a challenge that South Africa shares with many middle-income countries that lack universal healthcare coverage. Compared to nations with well-established public mental health infrastructure, such as those operating national health services with community mental health teams and free therapy referral pathways, South Africa’s public system offers restricted access to psychiatrists, psychologists, and counsellors, especially outside major urban areas. Waiting times for public mental health care can be extremely lengthy.

For those with private health cover (medical aid), access to mental health care improves considerably. Psychiatrists, psychologists, and counsellors practise across all major cities and regularly work with expat clients. If you are relocating with an existing mental health condition, arranging continuity of care before you leave — and confirming that your medical aid plan includes mental health treatment — is strongly advisable. The South African Depression and Anxiety Group (SADAG) is a well-respected national mental health NGO offering helplines, informational resources, and referrals to both long-term residents and newcomers.

Are there any health risks specific to expats living in South Africa?

Beyond the general disease environment, expats face a set of health considerations tied to climate acclimatisation, altitude, road safety, and the challenge of navigating an unfamiliar healthcare system.

Altitude is a relevant factor for those settling in Johannesburg and the surrounding Highveld plateau, which lies at approximately 1,750 metres above sea level. Newly arrived residents may experience mild altitude-related symptoms — including headaches, fatigue, and breathlessness — during their first few weeks. These effects typically subside without intervention, but individuals with pre-existing heart or lung conditions should consult a physician prior to relocating.

Road safety is a significant health concern. Accidental deaths from motor vehicle collisions and interpersonal violence represent important causes of mortality in South Africa. The country records one of the world’s highest road fatality rates relative to population size, and expats should adopt a defensive driving posture, refrain from driving at night in unfamiliar areas, and always use a seatbelt.

Emergency services can be limited beyond major urban centres. Ambulances are scarce or unreliable in most areas outside large cities and frequently lack advanced medical equipment. In an emergency situation, it may be faster and safer to travel to the nearest hospital by private vehicle or taxi rather than wait for an ambulance. Familiarising yourself with the location of the nearest private emergency facility is essential. The general emergency number is 10111; private emergency providers such as Netcare 911 (082 911) and ER24 (084 124) typically offer faster response times across many areas.

Practically speaking, expats should take the following steps to safeguard their health:

1. Obtain comprehensive private medical insurance or join a registered South African medical aid scheme before or immediately upon arrival.
2. Register with a GP (general practitioner) in your area as soon as possible — do not wait until you are unwell.
3. Get a full health screening within your first few months, including checks for blood pressure, blood glucose, HIV, and TB if you will be in a high-exposure environment.
4. Ensure all routine vaccinations are up to date, and take additional vaccines or prophylaxis appropriate to your region of residence.
5. If moving to a malaria-risk area, establish a relationship with a doctor familiar with tropical medicine and have a clear plan for accessing treatment quickly if symptoms develop.
6. Drink tap water in major cities (it is generally safe), but filter or boil water in rural or informal settlement areas.
7. Arrange continuation of any existing prescriptions before leaving your home country, and identify a local specialist if you have a chronic condition.

Where can expats find reliable health information and services in South Africa?

Several authoritative sources are available to help expats stay informed about health conditions, disease outbreaks, vaccination requirements, and available healthcare services in South Africa. Because guidelines, fees, and disease risks can shift — sometimes quickly — it is essential to verify information against official sources both before and after relocating.

• South African National Department of Health: The primary government resource for health policy, vaccination schedules, outbreak notifications, and public health guidance.
• National Institute for Communicable Diseases (NICD): Publishes surveillance data, outbreak warnings, and clinical guidance on infectious diseases relevant to South Africa — the country’s equivalent of bodies such as the CDC or UKHSA.
• Statistics South Africa (StatsSA): The national statistics authority, publishing mortality data, disease prevalence figures, and population health surveys.
• WHO South Africa Country Profile: Internationally comparable health indicators covering life expectancy, disease burden, and healthcare system performance.
• CDC Travellers’ Health — South Africa: Practical and regularly updated guidance on vaccinations, malaria prophylaxis, and health precautions for those travelling to or living in South Africa.
• South African Depression and Anxiety Group (SADAG): Mental health information, crisis helplines, and referrals to support services throughout the country.
• Your home country’s travel health authority: Before departing, consult the official travel health guidance issued by your home country — such as the UK’s TravelHealthPro or equivalent national portals — as these are updated regularly and calibrated to current risks.

Health guidelines, vaccination requirements, and disease patterns in South Africa can evolve, at times rapidly. Always verify current requirements with official sources before travelling or relocating, and revisit these sources periodically once you are settled in the country.

Frequently Asked Questions About Health Issues in South Africa

Do I need malaria tablets to live in South Africa?

Malaria risk is restricted to particular border regions: the Mopani and Vhembe Districts of Limpopo, the Ehlanzeni District of Mpumalanga, the uMkhanyakude District of KwaZulu-Natal, and Kruger National Park. Expats settling in Cape Town, Johannesburg, central Durban, or other large urban areas will not generally require malaria prophylaxis for everyday living. If you plan to visit game reserves or remote areas in the north of the country, however, you should take prophylaxis and apply mosquito-avoidance measures diligently. A travel medicine specialist can provide advice tailored to your specific itinerary and circumstances.

Is the water safe to drink in South Africa?

Tap water in South Africa’s principal cities — Cape Town, Johannesburg, and Pretoria among them — is treated to international standards and is generally safe to drink. Water quality can differ considerably in rural communities, townships, and informal settlements, where contamination or infrastructure breakdowns may be an issue. When there is any uncertainty, opt for bottled or filtered water, and boil water in rural settings as a precaution. Check local advisories if you are relocating to a smaller town or peri-urban area.

What vaccinations are recommended before moving to South Africa?

The CDC and most national travel health authorities advise confirming that routine immunisations — MMR, diphtheria-tetanus-pertussis, influenza, varicella, and polio — are current before departure. Hepatitis A and typhoid vaccines are also widely recommended. Travellers arriving from, or transiting through, a country where yellow fever transmission occurs must present a valid International Certificate of Vaccination or Prophylaxis confirming yellow fever vaccination administered at least 10 days before arrival. Consult your home country’s travel health authority and a registered travel medicine clinic for personalised and up-to-date guidance before relocating.

How serious is HIV in South Africa, and is it a risk for expats?

As of 2023, roughly 16.3% of South Africa’s population is living with HIV. For expats, the primary transmission risks involve unprotected sexual contact or exposure to infected blood — for instance, through needlestick injuries in healthcare settings. Practising safe sex, not sharing needles, and following standard infection control procedures substantially reduces individual risk. HIV testing is widely accessible and is incorporated as a routine element of health screening across South Africa.

Is private health insurance necessary for expats in South Africa?

Private health insurance — or enrolment in a registered South African medical aid scheme — is very strongly recommended for all expats. The public healthcare system is underfunded and often entails lengthy waiting times, restricted specialist access, and variable quality of care, especially away from major cities. Private hospitals and clinics in urban areas deliver a high standard of treatment, but out-of-pocket costs without cover can be considerable. Many expat employers include medical aid as a standard component of employment packages, but if yours does not, securing coverage before arrival should be treated as a priority.

Are mental health services accessible to expats in South Africa?

Private mental health professionals — psychiatrists, psychologists, and counsellors — practise in all of South Africa’s major cities and are accessible to expats, though the costs can be significant without medical aid coverage. Public mental health services are severely overstretched and are generally not a realistic option for expats in need of timely support. SADAG (the South African Depression and Anxiety Group) runs a national helpline and can assist with referrals to appropriate services. Practitioners in cities such as Cape Town and Johannesburg frequently have experience working with international clients and may offer consultations in multiple languages.

What are the main air quality and environmental health concerns in South Africa?

Air quality is a concern in certain regions, particularly the industrial Highveld — encompassing parts of Mpumalanga and Gauteng — where coal-fired power stations and mining activity contribute to elevated levels of atmospheric pollution. Expats with asthma or other respiratory conditions should research the air quality specific to their intended place of residence before committing to a move. Cape Town and other coastal cities generally benefit from cleaner air. The NICD and South Africa’s Department of Forestry, Fisheries and the Environment both monitor environmental health risks.

Is road safety a major health concern for expats in South Africa?

Road safety ranks among the most important everyday health risks for expats in South Africa. The country records a high road fatality rate, fuelled by speeding, impaired driving, and deteriorating road conditions in certain areas. Expats should drive defensively at all times, avoid unfamiliar routes after dark, and never operate a vehicle under the influence of alcohol. Saving the contact details for private emergency services — Netcare 911 (082 911) and ER24 (084 124) — is a sensible precaution, as public ambulance response times can be slow in areas beyond major urban centres.
