Wynn Macau has introduced enhanced mosquito control and health protection measures after Macau health authorities confirmed that a visitor diagnosed with dengue fever had recently stayed at the integrated resort.
The Macau Health Bureau said it was notified by authorities in mainland China on July 19 that an infected individual had visited the city. In response, officials designated a 100-meter risk zone around Wynn Macau, where mosquito eradication work is being carried out in cooperation with the resort. The control area reflects the typical flight range of Aedes mosquitoes, the primary carriers of dengue virus.
Wynn Macau said it has acted quickly to support the government’s response, implementing a range of preventive measures designed to reduce mosquito activity and protect guests, employees and visitors.
The company has intensified inspections of its indoor and outdoor facilities, removing standing water where mosquitoes can breed and increasing sanitation efforts across the property. Additional pest control operations are also being conducted, while staff have been instructed to monitor areas where water could accumulate following rainfall.
The operator is encouraging guests and employees to follow recommended health precautions, including using insect repellent and seeking medical attention if they develop symptoms associated with dengue fever, such as high fever, headaches, muscle pain or skin rash.
Health officials emphasized that dengue is not transmitted directly from person to person. Instead, the virus spreads through the bite of infected Aedes mosquitoes. While most patients recover within a few weeks, severe cases can lead to serious complications, making early detection and mosquito control essential.
Macau authorities have also urged residents and businesses across the city to eliminate stagnant water from flower pots, drains, containers and other locations that could become mosquito breeding sites. The campaign forms part of broader efforts to limit the risk of local transmission during the region’s warmer and wetter months, when mosquito populations are typically at their highest.
