WHO Raises Alarm on Potential Chikungunya Epidemic
The World Health Organization sounded a warning on Tuesday regarding a potential chikungunya virus outbreak, stressing the need for immediate action to prevent a global epidemic.
Officials highlighted that they are observing the same early warning signs as during a significant outbreak two decades ago and expressed a desire to avoid a repeat of that situation.
Chikungunya is a viral disease spread by mosquitoes, which causes fever and severe joint pain. The symptoms can be debilitating, and in some instances, it can even be fatal. “Although chikungunya isn’t widely recognized, it’s been found in 119 countries, posing a threat to roughly 5.6 billion individuals,” remarked Diana Rojas Alvarez from the WHO.
She reflected on the period from 2004 to 2005 when a major chikungunya epidemic affected small island territories in the Indian Ocean before spreading globally, impacting nearly half a million people.
“Currently, we’re witnessing a similar trend: since the start of this year, regions like Reunion, Mayotte, and Mauritius have reported significant outbreaks. It’s estimated that around one-third of Reunion’s population has already been infected,” she shared during a press briefing in Geneva.
Raising the Alarm
The symptoms of chikungunya resemble those seen in dengue fever and Zika virus, making accurate diagnosis quite challenging, according to the WHO.
Rojas Alvarez pointed out that, similar to two decades ago, the virus is now spreading to nearby areas such as Madagascar, Somalia, and Kenya, with epidemic transmissions also occurring in South Asia.
In Europe, cases connected to the outbreaks in the Indian Ocean have been recorded. Local transmissions have been reported in France, with suspected cases in Italy.
“Given that these transmission patterns were noted in the previous outbreak, the WHO is urging for swift action to prevent a recurrence of history,” Rojas Alvarez stated.
She mentioned the case fatality rate is under one percent, but “when considering millions of cases, that one percent can equate to thousands of deaths.”
“We’re raising the alarm now so that nations can prepare adequately, detect early, and bolster their capacities to avoid experiencing large-scale outbreaks,” she emphasized.
Tiger Mosquitoes
Rojas Alvarez elaborated that in areas where immunity levels are low, the virus can quickly cause extensive outbreaks, potentially affecting up to three-quarters of the population.
The chikungunya virus is primarily transmitted through bites from infected female mosquitoes, particularly the Aedes aegypti and Aedes albopictus, known as the tiger mosquito.
This latter species is moving further north due to climate change, which is largely influenced by human activity.
These mosquitoes tend to bite during the day, with heightened activity in the early morning and late afternoon.
The WHO has advised individuals to take protective measures, such as using mosquito repellent and ensuring water doesn’t stagnate in containers like buckets, which can serve as breeding grounds for mosquitoes.
