It is an annual ritual throughout Southeast Asia: As the rainy season starts and the humidity spikes, the mosquitoes come out. And they come with various diseases, including dengue which seems to be hitting hard this year.
Thailand is experiencing its biggest outbreak in more than two decades. The Philippines, Vietnam and Malaysia have also reported significant upticks in cases this year. The World Health Organization said there are big increases in Cambodia, Laos, China and Australia too.
Health authorities throughout Southeast Asia track the dengue outbreaks every year. Between 2017 and 2018, the numbers dropped but spiked up again this year.
