Key Global Health Priorities in 2017
In 2017, the global health landscape centered on noncommunicable diseases, ongoing infectious disease threats, and emerging mental health and antimicrobial resistance challenges. Leading causes of death and disability included cardiovascular disease, cancers, chronic respiratory diseases, and diabetes worldwide. At the same time, regions continued to face outbreaks and endemic diseases such as malaria, tuberculosis, HIV, and vaccine-preventable illnesses. Public health efforts focused on universal health coverage, primary care strengthening, and integrated disease surveillance. This overview clarifies conditions, scale, and responses, drawing on World Health Organization and comparable national data to provide a durable reference.
Noncommunicable Diseases: Persistent Global Burden
Noncommunicable diseases (NCDs) dominated mortality and morbidity in 2017 across high-, middle-, and low-income countries. These chronic conditions typically arise from a mix of genetic, physiological, environmental, and behavioral factors. Major shared risks include tobacco use, physical inactivity, harmful alcohol use, unhealthy diets, and air pollution. In 2017, NCDs accounted for the largest share of deaths globally, with notable impact on health systems and economic productivity. Addressing NCDs remained a priority through national guidelines, primary prevention campaigns, and targeted screening programs.
Cardiovascular Disease and Stroke
Cardiovascular disease and stroke were leading causes of death in 2017, driven by hypertension, elevated cholesterol, obesity, and tobacco use. Key prevention strategies included population-level salt reduction, hypertension screening, and improved access to essential medicines such as aspirin, statins, and antihypertensives. Health systems worked to strengthen prehospital emergency care for acute events and to promote timely access to cardiac rehabilitation where available.
Cancers and Access to Care
Cancer burden in 2017 reflected both aging populations and varying levels of diagnostic and treatment capacity. Common cancers included lung, breast, colorectal, prostate, and cervical cancers. Many regions expanded tobacco control, vaccination against cancer-related infections (such as HPV and hepatitis B), and public awareness about early warning signs. The care spectrum ranged from early detection and surgery to radiotherapy, chemotherapy, and supportive care, with considerable disparities linked to income, geography, and insurance coverage.
Chronic Respiratory Diseases and Diabetes
Chronic respiratory diseases, notably chronic obstructive pulmonary disease and asthma, contributed substantially to years lived with disability in 2017. Tobacco smoke, indoor and outdoor air pollution, and occupational exposures were important modifiable risks. Standard care involved inhalers, pulmonary rehabilitation, and management of comorbidities. Diabetes continued to rise, with type 2 diabetes linked to overweight and sedentary lifestyles. Care emphasized lifestyle modification, self-monitoring of blood glucose, oral medications, and complication screening for eyes, kidneys, and nerves.
Infectious Disease Threats and Endemics
Despite progress, infectious diseases remained a central concern in 2017, both as ongoing threats and in the context of outbreaks. High-burden targets included HIV, tuberculosis, malaria, and vaccine-preventable diseases. Many countries were implementing integrated service platforms to coordinate testing, treatment, and prevention while addressing social determinants that increase vulnerability.
HIV, Tuberculosis, and Malaria
- HIV: Antiretroviral therapy coverage expanded in 2017, yet gaps persisted in testing, linkage to care, and retention, particularly among key populations and in rural areas.
- Tuberculosis: Drug-susceptible and drug-resistant TB remained challenging, highlighting the need for rapid diagnostics, appropriate regimens, and infection control.
- Malaria: Endemic regions continued to report substantial cases and deaths, with bed nets, indoor residual spraying, and seasonal chemoprevention as core tools.
Vaccine-Preventable Illnesses and Outbreaks
Measles, diphtheria, pertussis, and other vaccine-preventable diseases posed risks where coverage slipped due to access barriers, conflict, or hesitancy. In 2017, many health authorities reinforced routine immunization, introduced catch-up campaigns, and strengthened surveillance to detect clusters early. Rapid response teams and risk communication were central to limiting transmission during localized outbreaks.
Mental Health and Neurological Conditions
Mental health conditions and neurological disorders gained prominence on public health agendas in 2017, driven by recognition of their impact on quality of life, productivity, and mortality. Common issues included depression, anxiety disorders, substance use disorders, and self-harm behaviors. Conditions such as dementia and epilepsy also affected significant numbers, especially in aging populations. Efforts focused on integrating mental health into primary care, reducing stigma, and expanding access to counseling and pharmacological treatments.
Depression, Anxiety, and Substance Use
- Depression and anxiety: Prevalence varied by region, with higher burdens in conflict-affected and humanitarian settings. Psychosocial interventions, peer support, and where appropriate antidepressant medications formed standard care.
- Substance use: Harm reduction approaches, including needle exchange and opioid substitution therapy where permitted, aimed to reduce transmission of infections and overdose deaths.
Environmental, Lifestyle, and Emerging Risks
By 2017, the health community placed growing emphasis on environmental, occupational, and lifestyle drivers of illness. Air pollution, unsafe water, and inadequate sanitation contributed substantially to respiratory, diarrheal, and cardiovascular disease. Increasing urbanization, changing diets, and reduced physical activity were associated with rising rates of overweight, obesity, and related NCDs. Public health strategies targeted policy measures such as tobacco taxation, healthier food standards, urban design that promotes activity, and pollution controls.
Health Systems Response and Preparedness
In 2017, universal health coverage and resilient health systems were central goals for many countries. Strengthening primary care, improving workforce distribution, and ensuring availability of essential medicines were common priorities. Countries invested in integrated surveillance, data systems, and laboratory networks to detect and respond to threats faster. Contingency planning and regular exercises supported rapid containment of outbreaks. These infrastructure investments were intended to deliver sustained gains in coverage, equity, and emergency readiness.
Comparative Snapshot: Health Issue Categories and Public Health Focus in 2017
| Health Issue Category | Public Health Focus in 2017 | Typical Metrics or Targets |
|---|---|---|
| Cardiovascular Disease | Hypertension control, tobacco reduction, healthy diets | Coverage of antihypertensives, population salt intake |
| Cancers | Tobacco control, vaccination, early detection | HPV and hepatitis B coverage, screening rates |
| Chronic Respiratory Diseases | Reduce risk factors, improve inhaler access | Prevalence of tobacco smoke, air pollutant levels |
| Diabetes | Lifestyle change, screening, complication management | Glycemic control rates, foot and eye screening coverage |
| HIV, TB, Malaria | Test and treat, case finding, vector control | ART coverage, TB case detection rates, ITN use |
| Vaccine-Preventable Diseases | Maintain high coverage, rapid outbreak response | Measles-containing vaccine coverage by age 1 |
| Mental Health | Integrate services, reduce stigma, increase access | Prevalence of treatment for depression and anxiety |
Limitations and Context
Reported figures and coverage levels can vary by data source, classification, and year of estimation. Indicators such as prevalence, incidence, and treatment coverage are often updated as new surveys and routine systems improve. This overview is intended as a durable explanatory baseline, not a prediction or recommendation for individual care decisions.
