FSM's Yap remains case-free
Covid-19 test results from three people of interest in the Micronesian state of Yap have all come back negative.
This included those from a male patient who died from pneumonia and coronavirus-like symptoms.
Kaselehlie Press reported the three clear results and another from the state of Pohnpei meant the Federated States of Micronesia had no confirmed Covid-19 cases.

The numbers of Covid-19 cases now cleared in the Northern Marianas continued to grow with two more patients recovered from the coronavirus.
However the health authorities still strongly advised the 11 recovered patients to continue practising social distancing as they could still have the virus in their system.
To date the CNMI has confirmed 14 Covid-19 cases, including two deaths.
The CNMI government was currently finalising plans to implement free mass testing throughout the commonwealth.
The CNMI also continued to receive more supplies with 26 ventilators, medical supplies, and UV lights for infection control shipped from Long Beach, California this week.
