President Anura Kumara Dissanayake’s office said on Tuesday that members of the army, navy and air force would join a specialized task force responsible for identifying and eliminating mosquito breeding grounds across the country.

The move comes as health authorities reported nearly 50,000 dengue infections and 29 related deaths so far this year. While the figures remain below the country’s record 2017 outbreak, officials warned that the recent acceleration in case numbers poses a significant public health challenge.

Dengue is transmitted by the Aedes mosquito, a species recognized by its black-and-white striped legs and known to breed in stagnant water. The disease can cause high fever, severe headaches, nausea, vomiting and muscle pain, while severe cases may lead to internal bleeding and death.

In a statement, the president’s office said authorities would intensify enforcement measures against individuals and institutions found to be allowing mosquito breeding sites on their properties.

“Laws will also be strictly enforced against those allowing mosquito breeding on their premises, in addition to setting up the special military unit,” the statement said.

A nationwide cleanup campaign targeting stagnant water and other mosquito breeding areas is scheduled to begin on Wednesday.

Sri Lanka has recorded a sharp increase in infections since early June, including more than 1,000 cases reported in a single day this week, according to official health data.

Kapila Kannangara, head of the government’s dengue control unit, said both public and private hospitals were already facing mounting pressure from the surge in patients.

“Hospitals are already under pressure,” Kannangara told reporters in Colombo. “We don’t want to have a situation like the one we faced in 2017.”

The country’s worst dengue epidemic occurred in 2017, when authorities recorded approximately 186,000 infections and 440 deaths, overwhelming healthcare facilities and prompting emergency response measures.

Health officials attributed the latest increase in cases to a combination of monsoon rains, stagnant water left behind by recent flooding and poor waste management practices that have created favorable breeding conditions for mosquitoes.

The World Health Organization has previously warned that climate change is contributing to the faster spread and broader geographic reach of dengue and other mosquito-borne diseases, particularly in tropical and subtropical regions.

Health authorities reported 550 confirmed cases as of Sunday, including 101 deaths and 19 recoveries, according to the latest situation update released late Monday. The outbreak was officially declared on May 15.

The vast majority of infections have been recorded in Ituri province, which accounts for more than 90 percent of confirmed cases. Additional cases have been identified in North Kivu and South Kivu provinces, while the virus has also crossed into neighboring Uganda.

Officials believe the true number of infections may be higher because the outbreak was detected weeks after transmission had already begun. Response efforts have been further complicated by the absence of an approved vaccine or treatment for the strain responsible for the current outbreak.

The outbreak has been linked to the rare Bundibugyo strain of Ebola virus, for which no approved vaccine or therapeutic treatment currently exists. This differs from the Zaire strain, which was responsible for most of Congo’s previous Ebola outbreaks and for which vaccines and treatments have been developed.

Authorities said the sharp increase in confirmed infections partly reflects expanded diagnostic capacity, which has enabled laboratories to process a backlog of previously collected samples.

Health workers operating in affected areas continue to face significant obstacles. Medical teams have been attacked on multiple occasions by residents frustrated by the outbreak response, while persistent skepticism among some communities has complicated surveillance and containment efforts.

Security concerns remain a major challenge across eastern Congo, where numerous armed groups continue to operate. Ongoing violence has limited access to several affected communities and disrupted disease-monitoring activities.

The World Health Organization said Monday that insecurity is restricting access for response teams, hindering surveillance operations and increasing the risk that new chains of transmission could go undetected.

The agency said the attacks on health personnel underscore the difficulties of responding to a public health emergency in conflict-affected areas and highlighted the importance of cooperation with local leaders and communities.

Eastern Congo has experienced repeated outbreaks of Ebola over the past decade, but health officials warn that the combination of armed conflict, delayed detection and the lack of approved medical countermeasures for the Bundibugyo strain presents a particularly complex challenge for containment efforts.

India’s foreign ministry said the two sides agreed to delay the summit, originally scheduled for May 28-31, citing the “emerging public health situation” across parts of Africa. The ministry said fresh dates for the gathering would be announced later.

The decision comes after the World Health Organization warned on Wednesday that the Ebola outbreak in eastern Democratic Republic of Congo posed a high regional risk, although the threat remained low globally.

The WHO said the virus had likely been circulating undetected for months before the outbreak was officially declared last week.

The latest outbreak, the 17th recorded in Congo, has already been linked to 139 suspected deaths from roughly 600 probable cases, according to health authorities. Ebola, a highly infectious hemorrhagic fever, has killed more than 15,000 people across Africa over the past five decades.

India said it stood ready to support Africa Centres for Disease Control and Prevention-led efforts aimed at containing the outbreak and strengthening public health response systems across the continent.

Delhi’s Indira Gandhi International Airport issued a health advisory on Thursday for passengers arriving from Democratic Republic of Congo as well as neighboring Uganda and South Sudan, reflecting growing concern over cross-border transmission risks.

The India-Africa Forum Summit is one of New Delhi’s key diplomatic platforms for engagement with African nations, covering trade, development cooperation, infrastructure and strategic partnerships. The postponement marks a rare disruption to the high-level forum amid heightened global vigilance over infectious disease outbreaks.

Tedros said he would travel to Tenerife in Spain’s Canary Islands to oversee the disembarkation of passengers, crew members and medical personnel from the Dutch-flagged cruise vessel MV Hondius, which is carrying around 150 people.“I arrived in Spain, where I will join senior government officials in a mission to Tenerife to oversee safe disembarkation,” Tedros said in a post on X.

Three passengers a Dutch couple and a German woman have died after contracting hantavirus during the voyage, while several others have fallen ill, according to health officials.The outbreak has drawn heightened international attention after authorities confirmed infections linked to the Andes virus strain, the only known hantavirus variant capable of transmitting between humans.

Most hantavirus infections are typically spread through contact with infected rodents or their droppings.Tedros said he had remained in direct contact with the ship’s captain, Jan Dobrogowski, and WHO physician Freddy Banza-Mutoka, who is on board the vessel.

“At this stage, there are no additional people on board showing symptoms of hantavirus,” Tedros said, adding that the World Health Organization continued to monitor the situation closely.

He also said the health risk to residents of the Canary Islands and the broader international public remained low.The MV Hondius is expected to dock in Tenerife on Sunday, where Spanish authorities have prepared surveillance and containment measures before arranging special flights to return passengers to their home countries.

Spain’s government said Tedros would meet Prime Minister Pedro Sanchez in Madrid before traveling to the Canary Islands alongside Spain’s health and interior ministers.Spanish ministry officials said the WHO chief would join a command center in Tenerife responsible for coordinating health controls, interagency cooperation and emergency response protocols linked to the ship’s arrival.

The incident has intensified scrutiny over infectious disease preparedness aboard international cruise vessels, particularly involving pathogens with rare but potentially serious transmission characteristics.

The campaign, led by the health ministry with support from UNICEF, the World Health Organization and Gavi, the Vaccine Alliance, has been rolled out across 18 high-risk districts, according to a joint statement.

Government data shows 17 confirmed deaths linked to measles so far, alongside 113 suspected fatalities and more than 7,500 suspected infections across the country. The outbreak has now spread to 56 of Bangladesh’s 64 districts, raising concerns over further transmission.

Authorities said the vaccination drive is prioritising children aged between six months and five years, particularly those who missed routine immunisation and are at higher risk of severe complications. Health officials described the campaign as a critical intervention to address immunity gaps exposed by the surge in infections.

UNICEF representative Rana Flowers said the agency was alarmed by the sharp rise in cases, warning that thousands of children, especially the youngest and most vulnerable, face heightened risk.

She said the resurgence underscored significant gaps in population immunity.Hospitals in several high-burden areas are operating beyond capacity, with limited resources to manage the influx of patients, officials said, adding to concerns about the outbreak’s trajectory.

The World Health Organization said the outbreak is likely to continue spreading in the coming days but could be brought under control following the large-scale vaccination effort. WHO representative Dr Ahmed Jamsheed Mohamed said the campaign would be key to preventing further child deaths.

Officials said the emergency drive is intended to complement existing routine immunisation programmes as authorities work to contain the outbreak and stabilise public health conditions.
