Health Protection Agency (HPA), on Friday, placed Kulhudhuffushi and Nolhivaram in Haa Dhaalu Atoll under monitoring.
According to the Health Emergency Operations Centre (HEOC), movement to and from the two islands was restricted after crew members of a boat registered at Kulhudhuffushi tested positive for COVID-19.
The restrictive measures will remain in place until the conclusion of contact tracing efforts.
Maldives currently records a total of 10,014 virus cases of which 1,300 are active cases, in addition to 8,673 recoveries and 34 deaths.
As one of the most densely populated cities in the world, Maldives' capital Malé continues to record a significant number of COVID-19 cases, similar to the first weeks following the first confirmed local transmission on April 15.
In addition to the Greater Male' Region, active virus cases are currently present in 22 inhabited islands as well as 26 resorts across the archipelago.
During last month, authorities tightened the safety measures implemented in the Greater Male' region, following an alarming upsurge of COVID-19 cases after the state initiated efforts to steer the country towards a 'new normal' with the phased easing of lockdown restrictions.
After a long period of recording over 100 daily cases, the numbers have fallen to two-digits during the most part of September. Within this same period, the number of recoveries saw a significant increase, bringing the number of recovered cases to 86.4 percent.
On March 12, WHO classified the spread of COVID-19 as a global pandemic. To date, the new strain of novel coronavirus has infected over 32.7 million people and claimed over 993,400 lives around the world. However, out of those infected, more than 24.1 million people have recovered.
