The Pacific Island Times reports Takeshi Kasai also advised Pacific island countries that have remained Covid-free to work hard to maintain their health status.
In a virtual press conference, Dr Kasai asked Pacific countries to immediately address the high incidence of non-communicable diseases in the region as people with these conditions have a very high risk of contracting the coronavirus.
He also said many small island countries in the region are vulnerable because of already difficult living conditions and limited healthcare capacity.
Dr Kasai said various Pacific islands may be Covid-free for now but they should continue to be vigilant and work on upgrading their response capabilities.
"Seize this moment to address non-communicable conditions and use this opportunity to have a healthier population, to avoid being at high-risk for Covid-19," Takeshi Kasai said.
