Malaysia has recorded 73 cases of heat-related illnesses nationwide from January 1 through early July 2026, along with four deaths linked to heat stress, the Health Ministry announced on July 7 during a media briefing on monsoon preparedness [1, 2, 3, 4].
Of the 73 reported cases, 59 involved heat exhaustion, the most common condition. There were six cases of exertional heat stroke and four cases of classical heat stroke. Additionally, two cases involved hyperpyrexia during the postpartum period, and two cases of heat cramps were recorded [1, 2, 3, 4].
The four fatalities included two adult males aged 42 in Penang and 22 in Kedah, and two children aged 2 in Negeri Sembilan and 4 in Perak.

Public healthcare facilities across Malaysia are fully equipped with necessary manpower, treatment resources, and medical supplies to provide prompt care for heat-related illnesses, the ministry said [1, 2, 3, 4]. The Health Ministry has intensified health education and advocacy programmes, particularly targeting high-risk groups such as the Orang Asli community.

Ongoing actions include surveillance of heat-related illnesses to identify and protect vulnerable populations, strengthening risk communication to the public, and enhancing healthcare system preparedness [1, 3, 4].
