WHO urges ‘surveillance system’ for those most vulnerable to extreme heat – National

The World Health Organization (WHO) is encouraging countries to set up a “strong surveillance system” to aid those most vulnerable to the health risks of extreme heat, which include heat stroke and exhaustion.

The most vulnerable include those with cardiovascular and respiratory diseases and diabetes, as well as older people, pregnant people, children and those who are homeless, according to the WHO.

In an emailed statement to Global News, a WHO spokesperson said such a system would allow public health authorities and policymakers to better understand the impacts of extreme heat on the community’s health, as well as “implement appropriate interventions to mitigate risks, and take timely actions to protect vulnerable individuals during heatwaves and extreme heat events.”

A 2021 report from the United Nations agency on heat and health in Europe said that “active surveillance” includes identifying susceptible subgroups through health system and population registries.

It gave the example of Italy’s Homeless Housing and Assistance Program (HHAP) formally requiring the drawing up of lists of susceptible subgroups, which are then sent to health authorities to implement active surveillance by general practitioners (GPs) and social services.

“We are very concerned about those who are more vulnerable,” Maria Neira, director of the public health, environment and social determinants of health department at the WHO, said during a press conference Wednesday.

“As an emergency, each government, local, central, they need to look at a very strong surveillance system to make sure that we protect all of those people potentially at risk immediately.”

Neira said that hospitals need to be prepared as high heat can exacerbate health issues.

The recommendation comes as parts of Europe, Asia and the United States are experiencing heat waves, with the hottest day on record hitting two weeks ago, according to WHO. The past two weeks in July have broken global temperature records and June was the warmest the month has ever been globally.

Neira also pointed out that urban planning is fundamental to battle the higher temperatures, as in making sure people have a cool place they can go if their home can’t be cooled.

“We will need places on a city-level for people to have a kind of climate refuge,” she said.

While heat has been the main issue for some places, others are facing other natural hazards, including heavy rains in South Korea and flash floods and landslides in northern India that have killed more than 100 people since June 1.

Climate change has been found to be a factor in erratic weather patterns, with Neira calling for more action to be taken.

“In the medium and long term, we need to decarbonize our society as well,” she said.
