The municipal centre for disease control reported 7,294 cases by week 11, more than triple the figure a year earlier, including 98 severe cases.
In week 11 alone, 837 infections were recorded, nearly double the recent weekly average. Since the start of the year, authorities have identified 288 outbreaks, including 162 in schools and 126 in the community.
Surveillance data showed the presence of the Enterovirus 71 strain, accounting for 25 per cent of samples tested. The strain is associated with rapid transmission, severe complications and a higher risk of death, particularly among children under five.
Health authorities have ordered strengthened prevention and control measures, with a focus on early detection and containment in high-risk settings such as nurseries, childcare groups and social protection centres.
Local health stations have been tasked with monitoring outbreaks, advising authorities and organising timely responses.
Schools have been instructed to ensure proper hygiene facilities, including access to clean water and soap, and to promptly report suspected cases.
Specialist hospitals in the city have also been assigned to train healthcare workers in diagnosis, treatment and infection control to help limit the spread of the disease.
