The summer 2020 Olympic and Paralympic games in Tokyo may be hit with dengue fever, scientists warn.
Concerns have been raised after the Japanese capital experienced an unexpected outbreak of the killer infection in 2014.
This shows the city has the climate and mosquitoes to support the virus returning, Harvard University researchers argue.
Researchers have now said Japan needs to step up its preparations ahead of the games in order to prevent an outbreak.
Dengue is treatable but up to a fifth of patients with a severe case of the mosquito-borne infection die without drugs. Most patients have no symptoms.
Scientists led by Dr Naoki Yanagisawa reviewed the preparedness of existing health services in Japan to cope with outbreaks.
Fears of an outbreak of the mosquito-borne virus in Tokyo are particularly high due to the Olympics taking place during the summer.
Prior to the city’s 2014 outbreak, up to 200 cases of dengue occurred every year in Tokyo, all of which were brought in from abroad.
During this time, the number of tourists who visited the city rose from 5.2 million in 2003 to 24 million in 2016, the year of the last Olympics.
But this is set to increase further due to Japan working to attract 40 million visitors from all over the world by 2020.
Infection control teams in the Asian country are normally ’robust’ at preventing outbreaks, according to the researchers.However, they said concerns are always raised when international visitors gather for ’special events’.
Dr Yanagisawa admitted it is ’virtually impossible to prevent any pathogen from entering a country just by enhancing border control’.
Writing in a report, the team said: ’Given dengue was introduced, chikungunya and Zika could be problematic as well.’Although an outbreak has not been recognized in Japan to date, there is always the possibility that these infections would cause an outbreak.
Participants and spectators of international sporting events such as the Olympics are at risk of acquiring imported and locally endemic infectious diseases.’
Dr Yanagisawa and colleagues identified 20 critical points to prevent a dengue outbreak in the journal PLOS Neglected Tropical Diseases.
They included recommendations that Japanese doctors are trained on how to manage tropical diseases.
While they also said provisions should be made to ensure adequate communication between medical staff and foreign patients.
Hotel workers should also be trained in managing tropical diseases and have a plan in place if they suspect a traveler is infected.
The study follows the norovirus outbreak that occurred at the Winter Olympics in PyeongChang, South Korea, earlier this year.
