Malaria Concerns Heighten Alongside Dengue Spread

Malaria Concerns Heighten Alongside Dengue Spread

United States: Experts are predicting a farther rise in dengue cases in the forthcoming times, and they believe that the recent shaft in cases is caused by an invasive variety of Asian mosquitoes that are developing in Europe as a result of the climate issue.

Dengue Cases Rising Steadily

European Centre for Disease Prevention and Control( ECDC) issued a warning on Tuesday, stating that dengue cases have steadily increased throughout Europe and some infections may come severe.

Invasive Tiger Mosquitoes Behind Dengue Surge

According to the agency, barracuda mosquitoes, an invasive species that’s primarily set up in tropical regions, have been discovered in 13 European Union countries. The discovery has been linked to a” significant” increase in dengue cases this time.

The ECDC reports that Austria, Bulgaria, Croatia, France, Germany, Greece, Hungary, Italy, Malta, Portugal, Romania, Slovenia, and Spain have all seen an increase in mosquito populations.

Tiger mosquitoes are the vector for diseases like dengue fever, chikungunya, and the Zika virus, which annually cause millions of cases globally and wreak havoc in tropical nations.

Effect of Climate Change

Previously, the species was restricted to warmer regions of Asia, Africa, and the Americas. But specialists claim that the summertime is creating the perfect environment for the emergence of these mosquitoes because of more travel and rising temperatures in Europe brought on by carbon pollution from burning coal, oil and gas.

The head of the ECDC, Andrea Ammon, stated, “Europe is already seeing how climate change is creating more favourable conditions for invasive mosquitoes to spread into previously unaffected areas and infect more people with diseases like dengue.”

 “More people traveling abroad from dengue-endemic nations will inevitably raise the risk of both local outbreaks and imported cases.”

In the EU, locally acquired dengue cases decreased to 130 last year from just 71 during the ten-year period between 2010 and 2021.

 With 1,572 instances in 2022 and 4,900 in 2023—”the highest number” since the start of EU monitoring in 2008—import cases were also increasing.

 Although there aren’t many infected individuals in Europe right now, Ms. Ammon predicted that “we will see an increase in the coming years.”

 Due to the muscular spasms and joint discomfort it causes, dengue fever—also referred to as “breakbone fever”—begins to manifest symptoms four to ten days following a bite. There are certain symptoms that resemble the flu.

When these mosquitoes bite an individual who is infected, they transfer the virus to another person.

The NHS states that it is typically not serious and commonly resolves on its own. Rarely, a more severe form of dengue can strike someone.

Concerns Over Dengue Outbreaks at Olympics

 Concerns about this year’s Olympics in July in France have already begun to arise.

 The authorities were “fully mobilized,” according to a French health ministry official, and ready for any potential infectious disease concerns during the Olympics.

According to the WHO,  dengue epidemics were documented in only nine nations prior to the 1970s. However, as global trade and travel became more interconnected and temperatures warmed, the disease eventually spread to nearly every country on Earth.

Ms. Ammon suggests that individuals adopt “personal protective measures,” emphasizing that “in those areas of Europe most at risk, early detection of cases, timely surveillance, further research and awareness-raising activities are paramount.”

Urgent Measures Needed to Combat Dengue Spread

 There are other concerns besides the increase in dengue cases. Experts caution that future circumstances could potentially result in a rise in malaria cases.

The head of the UN health agency’s dengue programme, Dr. Raman Velayudhan, issued a warning last year about a “very worrying” increase in the virus’s global spread in 2022, saying that the climate crisis “played a key role” in it.

 In the southeast of England, officials in the UK have also discovered the tiger mosquito many times since 2016.

 A 2019 study that was out in the of the Royal Society Interface suggests that by the 2060s, these mosquitoes may spread to almost every part of England and Wales.

 There are worries that, in the appropriate circumstances, malaria cases may rise on the continent in the future.
