Chikungunya: Could It Happen in Nigeria?

The World Health Organisation, WHO, on Monday warned of a global resurgence of chikungunya, a mosquito-borne viral disease, following major outbreaks in La Réunion, Mayotte, and Mauritius since March.

However, Nigeria is not yet on the list of countries currently battling chikungunya outbreaks, but public health experts warn that the nation’s environmental conditions make it highly susceptible.

The outbreaks, WHO said, have now spread to South and East Asia, mirroring patterns seen 20 years ago when a wave that began in the Indian Ocean swept across continents, infecting nearly half a million people.

“This further spread is highly concerning because it follows a trajectory we’ve seen before-one that can quickly escalate into a global public health emergency,” WHO stated in its advisory.

The agency also confirmed that the virus continues to spread in endemic regions, with the Americas already reporting over 200,000 cases this year alone.

WHO said that about 5.6 billion people worldwide now live in areas suitable for the spread of Aedes mosquitoes-the Aedes aegypti and Aedes albopictus which transmit chikungunya along with other diseases such as dengue and Zika.

Chikungunya has been detected or transmitted in 119 countries globally. In communities with little or no immunity, WHO warned that the disease can infect up to three-quarters of the population in a short period, severely straining healthcare systems.

WHO’s Technical Lead for Arboviruses, Dr Diana Rojas-Alvarez said the warning was being sounded early to give countries a fighting chance.

“We are raising the alarm early so countries can prepare early through surveillance, mosquito control, and public awareness-to avoid overwhelming health services,” she explained

The World Health Organisation (WHO) confirmed that more than 1,300 people have died in Europe since June 21 in connection with the record-breaking heatwave roasting much of the continent.

WHO chief Tedros Adhanom Ghebreyesus said on X that tens of millions have been braving the extreme temperatures in Europe as a deadly heatwave moves eastwards, with some countries announcing rising death tolls and health services warning of saturation.

On Sunday morning, French health officials said there had been around 1,000 more deaths than expected in that country just since Wednesday.

“Heat stress is often called the ‘silent killer’ – and European homes, workplaces and schools were not built for these temperatures,” he said.At least 191 million people are forecast to endure temperatures of at least 35 °C on Sunday in Europe, with the heat particularly intense in Germany, the Czech Republic, Hungary and Poland, according to AFP estimates.

One after another the calls came in from hospitals; criminals were infecting computer networks in a mass hack that was putting countless lives at risk.

At Bucharest’s national cyber-security centre (DNSC) they watched helplessly as the hackers spread across Romania through a popular piece of medical software.

Cyber-chief Dan Cimpean had a tough decision to make, but it was the only option they had.

The order went out to more than 100 hospitals. Disconnect from the internet, now.

The cyber-attack on Romania’s hospitals in February 2024 is one of the worst to target healthcare systems around the world, but these incidents are becoming increasingly common.

Healthcare is now the most targeted area of critical national infrastructure, the FBI has said recently.

Cutting off 100 hospitals in Romania from the internet stopped the hackers in their tracks, buying time to work out how bad the attack was.

But it meant no connected devices, emails or web browsers.

Medical staff had to switch to pen and paper, improvising workarounds to protect patients while IT teams scrambled and the national cyber response centre tried to find out how the hackers had got in – and how they could stop them.

Their actions over four days from 10 February 2024, and those of the doctors and nurses, have been widely praised.

How they reacted and how they coped has become a test case for disaster planners internationally, as officials look for advice on responding to a mass hospital hack.
