A Malaysian health official has warned citizens to take steps to eliminate mosquito breeding spots as dengue fever cases have spiked.
The number of reported cases of the infection, which causes severe fever, headaches and joint pain and can trigger fatal haemorrhaging and death, has soared compared to last year, and deaths have doubled.
Between January and late October, 28,200 cases and 60 deaths were recorded, according to government statistics.
There were 17,800 cases and 29 deaths during the same period last year.
Officials have said a key factor has been frequent heavy downpours in recent weeks.

The disease is spread by the Aedes aegypti mosquito which, like other mosquitoes, breeds in stagnant water and other damp spots.
Lokman Hakim Sulaiman, who heads the health ministry's public health division, said on Monday the ministry was calling on all Malaysians to "destroy all the breeding places," such as illegal dump sites.
"We are trying to get the community to help make the environment free of the mosquitoes," he said, adding the ministry was working with local-level health officials to spread awareness.
He said prevention was key, due to the lack of proven vaccines or treatment.
"The problem with dengue is that we don't have enough tools to manage the situation. It's a global challenge," he said.
Dengue fever affects between 50 and 100 million people in the tropics and subtropics each year.
Countries ranging from Nicaragua to Pakistan have in recent weeks reported deadly outbreaks.
In Singapore, which borders Malaysia, more than 19,000 people have been infected this year, according to a government website tracking the problem.
Five have died.
The previous high for number of cases in Singapore came in 2005, when 13,984 infections were recorded and 25 people died, according to official data.
