Wynn Macau Takes Measures to Protect Guests From Dengue Fever-Carrying Mosquitoes

Wynn Macau says it’s proactively responding to a possible viral infectious disease outbreak after a guest with dengue fever recently stayed at the resort casino.

The Macau Special Administrative Region Government’s Health Bureau reported on Sunday (July 19) that a confirmed infected person carrying dengue fever had stayed on the downtown peninsula at Wynn Macau.

“In the coming days, the Bureau will work with relevant venue management entities to carry out mosquito control measures in the risk area around Wynn. Since the activity range of Aedes mosquitoes extends to roughly 100 meters (328 feet) around breeding sites, a 100-meter radius has been designated as the risk area and the scope of this mosquito control operation,” the Macau Health Bureau said.

Wynn Macau, Wynn Resorts’ first casino in China’s Macau, opened in 2006. The five-star luxury property includes 1,014 guestrooms and suites across two hotel towers and a casino floor with 253 table games and 911 slot machines.

Wynn Macau is located between MGM Macau to its south and Casino Lisboa to its north.

Dengue Fever

Dengue fever is a viral infection spread by mosquitoes, specifically the Aedes mosquito. Dengue is most common in tropical and subtropical regions of the world, with Southeast Asia a hotbed for the disease.

Dengue fever is not contagious human-to-human but is instead spread by a mosquito biting an infected person and passing it on when it bites someone else.

Common symptoms of dengue fever include sudden fevers of up to 104 degrees Fahrenheit, severe headaches, eye pain, nausea, vomiting, rashes, and joint and muscle aches. Less common symptoms, typically associated with “severe dengue,” are severe abdominal pain, persistent vomiting, shortness of breath, nose and mouth bleeding, and blood in the vomit or stool.

While most people recover from dengue fever in about two weeks, death is possible, although rare. The World Health Organization (WHO) says there is no specific treatment for dengue or severe dengue, with patients commonly advised to rest, drink plenty of fluids, and manage their pain with acetaminophen. Ibuprofen is to be avoided, as it could increase the risk of bleeding and stomach irritation.

Pandemic Risk Low

COVID-19 is thought to have originated in China’s Wuhan, the capital of Hubei.  

While epidemiologists say dengue fever could theoretically reach pandemic levels, the virus is widely classified as an ongoing, widespread hyperendemic disease. However, because of global warming, which is improving environments for mosquitoes, dengue fever has surged in recent years, with a record 14 million cases and 9,000 deaths reported in 2024.

“Urgent focus is needed on vaccine development, novel therapies, improved patient management, vector control, community awareness, and early detection of secondary and severe dengue cases,” researchers at Keele University in the United Kingdom concluded in a March 2025 study.

“Prioritizing dengue in the WHO’s research agenda, alongside global collaboration and investment as well as standardization of data, is crucial for providing meaningful comparison across countries, and a timely and coordinated public health response in reducing its burden and preventing future outbreaks,” the Keele researchers recommended.
