CNN —Dengue cases are surging in the Americas, with cases reported topping 5.2 million as of this week, surpassing a yearly record set in 2023, according to the Pan American Health Organization (PAHO). PAHO spokesperson Ashley Baldwin told CNN Thursday that 5,214,480 cases of dengue have been reported in the Americas as of Wednesday. In all of 2023, the total number of cases reported in the region was 4,572,765. “We are in an emergency situation because of dengue,” PAHO Director Jarbas Barbosa said in a news briefing Thursday. Early detection and access to proper medical care will reduce the probability of dying due to severe dengue,” Baldwin added.

Paulo Cesar Gomes, a 56-year-old entomologist, found some mosquito larvae swimming in shallow rainwater inside a car bumper. Captured mosquitos and larvae are kept alive and brought to a city laboratory to be tested for dengue. At locations with positive tests, health agents spray the walls with a product that kills mosquitos and then monitor the location for weeks. In Rio, more than 80% of mosquito breeding sites are located in residential properties, health officials say. Health workers and volunteers went door to door, pacing up and down the narrow streets of Rio's Tabajara working-class neighborhood, or favela, to spread the word.

By Ricardo Brito and Anthony BoadleBRASILIA (Reuters) - Dengue fever has surged in Brazil's hot rainy season, forcing health authorities to take emergency measures and start mass vaccination against the mosquito-borne illness. In the first five weeks of this year 364,855 cases of infection have been reported, the Health Ministry said, four times more than dengue cases in the same period of 2023. The rapid spread of dengue has caused 40 confirmed deaths, the ministry said, and a further 265 are being investigated. The Health Ministry has set up an emergency center to coordinate operations against dengue across Brazil. Dengue fever symptoms include a high fever, headache, vomiting, muscle and joint pains, and an itching skin rash.

CNN —The mayor of Rio de Janeiro, Eduardo Paes, has declared a state of public health emergency due to a dengue epidemic, according to CNN affiliate CNN Brasil. The surge in dengue cases comes as Rio and the rest of the country gear up for carnival celebrations where millions of people pour onto the streets for parades and block parties. In January alone, Rio’s city health network had 362 people hospitalized due to dengue, a record number, topping the previous high from 2008, CNN Brasil reported. According to data from the Rio de Janeiro City Council’s Epidemiological Observatory panel, 11,202 cases have already been registered in 2024.

LONG BEACH, Calif. (AP) — Two people in Southern California have come down with dengue fever without traveling outside the United States, where the mosquito-borne illness is rare, health officials said. A Pasadena resident was confirmed to have dengue last month but is recovering, officials said. “This is the first confirmed case of dengue in California not associated with travel and is instead an extremely rare case of local transmission in the continental United States,” the Pasadena Public Health Department announced. On Wednesday, Long Beach officials announced another domestically contracted dengue case and said that person has recovered. The new California cases were not part of that count.

OUAGADOUGOU, Oct 19 (Reuters) - Burkina Faso's health ministry has declared a dengue fever epidemic amid the deadliest outbreak in years in which more than 200 people have died and new cases are rising sharply. Lack of treatment or misdiagnosis, common in poverty-stricken countries such as Burkina Faso where healthcare is spotty, increase the chance of death. Burkina Faso's outbreak dwarfs other African outbreaks in recent years. According to figures from the Africa Centres for Disease Control and Prevention, dengue killed 18 people in Burkina Faso in 2017 and 15 in 2016. The health ministry said that it was providing free rapid diagnostic tests and had organised spraying of insecticide in public places to counter the spread.

By Jennifer RigbyLONDON (Reuters) - 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. Many cases go unrecorded, but in 2022 4.2 million cases were reported worldwide and public health officials have warned that near-record levels of transmission are expected this year. Earlier this week, the WHO recommended Takeda Pharmaceuticals' Qdenga vaccine for children aged 6 to 16 in areas where the infection is a significant public health problem. Qdenga is also approved by the EU regulator, but Takeda withdrew its application in the United States earlier this year, citing data collection issues. Dengue is spread by infected Aedes aegypti mosquitoes, which behave differently to the malaria-carrying kind.

TEGUCIGALPA, Honduras (AP) — For decades, preventing dengue fever in Honduras has meant teaching people to fear mosquitoes and avoid their bites. Enriquez, a 52-year-old mason, had volunteered to help publicize a plan to suppress dengue by releasing millions of special mosquitoes in the Honduran capital. The Aedes aegypti mosquitoes that most commonly spread dengue have been resistant to insecticides, which have fleeting results even in the best-case scenario.

Dengue-infected people are treated at the Mugda Medical College and Hospital in Dhaka, Bangladesh, on August 7. The global number of dengue cases has already increased eight-fold in the past two decades, according to WHO. As the climate crisis worsens, mosquito-borne diseases like dengue, Zika, chikungunya and yellow fever will likely continue to spread and have an ever greater impact on human health. Mahamud said the climate crisis and this year’s El Nino weather pattern – which brings warmer, wetter weather to parts of the world – are worsening the problem. Calling these outbreaks a “canary in the coalmine of the climate crisis,” Mahamud said “global solidarity” and support is needed to deal with the worsening epidemic.

NY State Department of Agriculture is encouraging residents to kill the invasive spotted lanternfly. The annual cost of invasive alien species now exceeds $423 billion annually, according to a new report by the Intergovernmental Platform on Biodiversity and Ecosystem Services, an organization that is a part of the United Nations. The report claims over 37,000 so-called alien species have been transported due to human activities around the world. Invasive alien species, as defined by the report, are species that are known to "have become established and spread, which cause negative impacts on nature and often also on people." The costs of invasive species have quadrupled every decade since 1970, according to the report.

Hospitals, especially in capital Dhaka, are struggling to find space for the large number of patients suffering high fever, joint pain and vomiting, health officials said. There is no vaccine or drug that specifically treats dengue, which is common in South Asia during the June-to-September monsoon season, when the Aedes aegypti mosquito that spreads the deadly virus thrives in stagnant water. This year's deaths already top the previous record of 281 from last year, with the number of people infected just behind the 62,423 cases of 2022.

According to the DSHS, although Texas sees about 120 malaria cases a year from international travelers, the last locally acquired case in Texas was detected in 1994. About 1,400 miles away in Sarasota County, Florida, however, two more cases of locally transmitted malaria infections have been identified this year — one in May and one in June.

There were 71 cases of the disease - which generally causes fever and muscle pain but can be more severe and even sometimes fatal - last year, mainly in France. The health agency warned at a press conference on Thursday there is an increasing risk of a number of mosquito-borne diseases in the European region, including dengue, zika, chikungunya and West Nile virus, linked to the changing climate and the spread of mosquitoes carrying the viruses. “If this continues, we can expect to see more cases and possibly deaths from diseases such as dengue, chikungunya and West Nile fever," said Andrea Ammon, ECDC director. Aedes aegypti, which spreads diseases including dengue, yellow fever and chikungunya, became established in Cyprus last year and could make further inroads, it said. While the rates of some mosquito-borne diseases in Europe have not risen dramatically in recent years or even fallen slightly, such as malaria and zika, others have seen a "striking" rise, particularly dengue, the ECDC said.
