The two are from Aizwal district, he said.
"They were in quarantine centres and their samples were tested at the Zoram Medical College. The two new patients remain asymptomatic," the official said.
With these fresh patients, the number of active COVID-19 cases increased to 23, while a person who tested positive after returning from Amsterdam in March has recovered from the disease.
A total of 302 samples were tested on Friday at the ZMC, the official said, adding that the government had received an RT-PCR machine from Manipur.
"The new machine has been installed at the ZMC and this will help increase the number of COVID-19 tests in Mizoram," he said.
According to the International Atomic Energy Agency, the real-time reverse transcription-polymerase chain reaction (RT-PCR) technique is highly sensitive and specific and can deliver a reliable diagnosis as fast as three hours. COR BDC BDC
