Here are 10 of the most urgent health challenges we’ll face in the 2020s, according to WHO

The world can’t afford to do nothing – that’s the World Health Organization’s message on the release of its report listing the most urgent health challenges for the coming decade.

All of the health challenges on the WHO list are urgent – and many are linked. And each challenge requires a coordinated effort from the global health sector, policymakers, international agencies and communities, the organization says. However, there is concern global leaders are failing to invest enough resources in core health priorities and systems.

These are the main challenges on the list.

1. Elevating health in the climate debate The climate crisis poses one of the biggest threats to both the planet and the health of the people who live on it.

Emissions kill around 7 million people each year, and are responsible for more than a quarter of deaths from diseases including heart attacks, stroke and lung cancer. At the same time, more – and more intense – extreme weather events like drought and floods increase malnutrition rates and help spread infectious diseases like malaria.

2. Delivering health in conflict and crisis

The already difficult task of containing disease outbreaks is made more challenging in countries rife with conflict.

Nearly 1,000 attacks on healthcare workers and medical facilities in 11 countries were recorded in 2019, leaving 193 medical staff dead. Despite stricter surveillance, many healthcare workers remain vulnerable.

For the tens of millions of people forced to flee their homes, there is often little or no access to healthcare.

3. Making healthcare fairer

The gap between the haves and have-nots is growing, especially in terms of access to healthcare.

People in wealthy nations can expect to live 18 years longer than their poorer neighbours, and wealth can determine access to healthcare within countries and individual cities, as well. Rising global rates of diseases like cancer, diabetes and chronic respiratory conditions have a greater impact on low- and middle-income countries, where medical bills can quickly deplete the limited resources of poorer families.

4. Expanding access to medicines Although many in the world take access to medication for granted, medicines and vaccines are not an option for almost one-third of the global population.

The challenge of expanding access to medicines in areas where few, if any, healthcare products are available includes combatting substandard and imitation medical products. In addition to putting lives at risk by failing to treat the patient’s condition, these products can undermine confidence in medicines and healthcare providers.

5. Stopping infectious diseases

Infectious diseases continue to kill millions of people, most of them poor. This picture looks unlikely to change in the near future.

Preventing the spread of diseases like HIV, tuberculosis and malaria depends on sufficient levels of funding and robust healthcare systems. But in some areas where they are most needed, these resources are in short supply.

Greater funding and political will is required to develop immunization programmes, share data on disease outbreaks and reduce the effects of drug resistance.

6. Preparing for epidemics

Airborne viruses or diseases transferred by mosquito bite can spread quickly, with potentially devastating consequences.

Currently, more time and resources are spent reacting to a new strain of influenza or an outbreak of yellow fever, rather than preparing for future outbreaks. But it’s not a question of if a dangerous virus will come about – but when.
