Japan: Heatwave in south leaves at least eight dead as of July 16 /update 3

Event

An ongoing heatwave in southern Japan has left at least eight people dead as of Monday, July 16, following recent flooding and landslides in many of the same regions which have left at least 210 others dead and 19 people missing. The lingering effects of the flooding have seemingly compounded the health risks posed by the heatwave, as tens of thousands of homes in affected areas remain without power and running water; in turn, the heat has also complicated flood recovery efforts.

The areas most severely affected by the heatwave include the prefectures of Aichi, Okayama, Hiroshima, and Ehime, where dozens have been hospitalized for heatstroke or exhaustion. The heat, combined with standing water and widespread debris, has also raised health concerns - notably regarding the spread of mold, mildew, and water- and mosquito-borne diseases, in addition to the general lack of access to health care. High temperatures are forecast to continue in many areas affected by the floods in the coming days.

Context

These high temperatures could be particularly hazardous to the health of the elderly, young children, and people suffering from chronic illnesses such as cardiac issues, hypertension, and diabetes. Symptoms of heatstroke include high fever, hot, red, dry skin, headache, nausea, drowsiness, intense thirst, confusion, convulsions, and loss of consciousness.

Advice

Individuals in Japan are advised to avoid areas still affected by flooding, monitor weather reports, and adhere to any instructions or advice issued by local authorities. Due to high temperatures, avoid strenuous outdoor activity, remain indoors as much as possible between noon and 16:00 when temperatures tend to peak, remain well hydrated (i.e. with sugar-free, non-alcoholic beverages), and wear loose, light-colored clothing. Do not hesitate to seek medical attention if displaying symptoms of heatstroke.
