The number of dengue fever cases dropped by more than half last year, with only three deaths, a health official said.
Huy Rekol, director of the National Centre for Parasitology, Entomology and Malaria Control, said there were 6,372 cases of dengue fever in the country in 2017.
In 2016, there were 12,843 cases, with 18 deaths.
“We think this is a very good achievement because communities are now more understanding about prevention and protection, and they have been taking action to eliminate the sources of mosquitoes and also dengue fever,” Dr Rekol said.
The three deaths last year were all children, aged between five and nine.
“Part of the reason that dengue is decreasing is that health services are better and more widely available. This means patients can find health services to receive timely and effective treatment,” said Dr Rekol.
“We really appreciate the ability of our health services to limit deaths from dengue.”
Despite this, Dr Rekol said efforts must continue to prevent future outbreaks.
Most cases last year were in Phnom Penh, he added.
“Firstly, we all have to fight to eliminate the places where mosquitoes breed,” Dr Rekol said.
“Secondly, people must seek urgent medical attention if they think they have the disease. They must not treat it by themselves.”
Earlier this month, officials from the National Centre for Parasitology, Entomology and Malaria Control said the number of malaria cases last year was roughly the same as it was in 2016.
There were more than 23,000 cases of malaria in 2017, with only one reported death.
