\nLONDON:
\n<\/strong><\/p>\n

Dengue fever will become a major threat in the southern United States, southern Europe and new parts of Africa this decade, the WHO’s chief scientist said, as warmer temperatures create the conditions for the mosquitoes carrying the infection to spread.<\/p>\n

The illness has long been a scourge in much of Asia and Latin America, causing an estimated 20,000 deaths each year. Rates of the disease have already risen eight-fold globally since 2000, driven largely by climate change as well as the increased movement of people and urbanization.<\/p>\n

Many cases go unrecorded, but in 2022\u00a04.2 million cases were reported\u00a0worldwide and public health officials have warned that near-record levels of transmission are expected this year.\u00a0Bangladesh\u00a0<\/a>is currently experiencing its worst-ever outbreak, with more than 1,000 deaths.<\/p>\n

\u201cWe need to talk much more proactively about dengue,\u201d Jeremy Farrar, an infectious diseases specialist who joined the World Health Organization in May this year, told Reuters.<\/p>\n

\u201cWe need to really prepare countries for how they will deal with the additional pressure that will come\u2026 in the future in many, many big cities.\u201d<\/p>\n

Farrar previously spent 18 years working in Vietnam on tropical diseases including dengue. He later headed up the Wellcome Trust global health charity and advised the UK government on its COVID-19 response before joining the WHO in May this year.<\/p>\n

Farrar said the infection is likely to \u201ctake off\u201d and become endemic in parts of the United States, Europe and Africa – all regions where there has already been some limited local transmission – as global warming makes new areas hospitable to the mosquitoes that spread it. That will put acute pressure on hospital systems in many countries, he warned.<\/p>\n

\u201cThe clinical care is really intensive, it requires a high ratio of nurses to patients,\u201d he said. \u201cI really worry when this becomes a big issue in sub-Saharan Africa.\u201d<\/p>\n

Most people who get dengue do not have symptoms, meaning case rates are thought to be far higher than the reported numbers. Those who do can experience fever, muscle spasms and joint pain so severe it is known as \u201cbreak-bone fever.\u201d In severe cases \u2013 less than 1% – it can be fatal.<\/p>\n

There is no specific treatment for dengue, although there is a vaccine available. Earlier this week, the WHO recommended Takeda Pharmaceuticals’\u00a0Qdenga vaccine for children aged 6 to 16 in areas where the infection is a significant public health problem.<\/p>\n

Qdenga is also\u00a0approved by the EU\u00a0regulator, but\u00a0Takeda withdrew\u00a0its application in the United States earlier this year, citing data collection issues. Takeda said it was still in talks with the U.S. Food and Drug Administration about the vaccine.<\/p>\n

Preparing new regions of the world to deal with dengue means ensuring that any public health funds get spent in the right areas, Farrar said, including on the best way to control the mosquito.<\/p>\n

Dengue is spread by infected Aedes aegypti mosquitoes, which behave differently to the malaria-carrying kind. For example, they bite people indoors, and they bite all day rather than overnight. They also breed in very shallow water.<\/p>\n

Farrar said proper prevention would include triaging plans for hospitals as well as scientific innovation alongside other key factors, such as urban planning, to avoid areas of standing water near or in houses.<\/p>\n

\u201cWe need to combine different sectors that are not used to working together,\u201d he said.<\/p>\n<\/div>\n
