Measles cases arise nearly 80% in wake of Covid chaos, with fears other diseases could follow | viruses

Measles cases have arisen nearly 80% worldwide this year amid disruption caused by Covid-19, the UN has said, warning that the rise of the “canary in a coalmine” illness indicated that outbreaks of other diseases were likely to be on the way.

The coronavirus pandemic has interrupted vaccination campaigns for non-Covid diseases around the world, creating a “perfect storm” that could put millions of children’s lives at risk, the UN’s children’s agency Unicef ​​and the World Health Organization (WHO) said in a statement.

Measles is a disease caused by a virus that attacks mainly children. The most serious complications include blindness, brain swelling, diarrhoea, and severe respiratory infections. Vaccination uptake of at least 95% is the best way to avoid it spreading, though many countries fall far short of that goal – Somalia is at just 46%, according to the UN data.

Globally, more than 17,300 meal cases were reported in January and February, compared with about 9,600 during those months last year, according to new data from the UN agencies.

There have been 21 large and disruptive measles outbreaks in the 12 months to April, most of them in Africa and the eastern Mediterranean, the data showed.

Christopher Gregory, senior health adviser in Unicef’s immunization section, told Agence France-Presse that because measles was the “most contagious vaccine-preventable disease” it often served as a warning sign. “Measles is what we call the tracer, or the canary in the coalmine, that really shows us where those weaknesses in the immunization system are,” he said.

Yellow fever was among the diseases that could arise next, he said, after rising cases were reported in West Africa.

“We’re particularly worried about those countries that are most fragile, where the healthcare systems are already really struggling, where they’re still trying to deal with the impacts of Covid on top of these outbreaks,” he said.

Somalia recorded by far the most measles cases in the past 12 months, with more than 9,000, the UN data showed, followed by Yemen, Afghanistan, Nigeria and Ethiopia – all countries experiencing some form of conflict.

There are also fears that the war in Ukraine could spark a resurgence in the country after it recorded Europe’s highest rate of meals between 2017 and 2019. Gregory said that it had been very difficult to keep track of any disease in Ukraine since the war began, adding that the biggest concern was “what we could be missing”.

The UN agencies said that 57 vaccination campaigns in 43 countries postponed at the start of the pandemic had still not been completed, affecting 203 million people – most of them children.

Covid also continues to pile pressure on healthcare facilities and drag staffing and care away from vaccination for longstanding deadly diseases. “The impact of these disruptions to immunization services will be felt for decades to come,” WHO chief Tedros Adhanom Ghebreyesus said in a statement.

“Now is the moment to get essential immunization back on track and launch catch-up campaigns so that everybody can have access to these life-saving vaccines.”

Gregory said it was time to put childhood immunization on “at least the same level of priority as finishing Covid vaccination”.
