Call for action on rising cholera cases, and other health stories

Immediate action is needed to prevent a “multi-year upsurge in cholera cases worldwide”, according to the organization that manages the world’s stockpile of cholera vaccine.

The International Coordinating Group (ICG) on Vaccine Provision has warned that millions of people are at risk from the disease due to lack of clean water, soap and toilets, and a shortage of the vaccine used to prevent the disease.

Cases of cholera – an acute disease transmitted through the ingestion of contaminated food or water – have been rising globally since 2021. In 2022, 473,000 cases were reported to the World Health Organization (WHO) – more than double the number reported the previous year. Preliminary data for 2023 shows a further surge, with over 700,000 cases reported.

Cholera is preventable and treatable, and according to the WHO, cases have been declining in previous years. It recommends actions including investing in access to safe water and sanitation, testing and quickly detecting outbreaks, and fast-tracking the production of vaccine doses to better prevent cases.

Just seven countries worldwide are meeting an international air quality standard, according to a new report.

The report from air-quality technology company IQAir reviews air quality data for 2023 across 134 countries and regions, looking at whether they meet the WHO annual guideline limit for PM2.5 – particulate matter with a diameter of 2.5 microns or less. These tiny particles – measuring less than the width of a human hair – enter the air from many sources, including fires, transport and industry.

The report found that of the countries monitored, just Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand met the WHO’s annual guideline.

Exposure to PM2.5 air pollution has been linked to many health conditions, including asthma, lung disease and cancer. “The burden of disease attributable to air pollution is now estimated to be on a par with other major global health risks such as unhealthy diet and tobacco smoking,” the WHO says.
