The jawans had recently returned from Dholcherra in neighbouring Assam.
The two personnel were initially placed under quarantine at Vanhne camp in Lunglei district upon their arrival on June 25. A week later, they were shifted to their place of deployment at Dawngzawl in Serchhip district. There, too, the jawans were put in isolation.
One of them, aged 51 years, had developed symptoms of COVID-19. The other one, aged 30 years, exhibited no such symptoms, the official said.
Test results, however, showed that both of them have contracted the disease, he said.
With the detection of the two fresh cases, the number of BSF personnel who have tested positive for COVID-19 in Mizoram climbed to 12, the official added.
Meanwhile, a statement by the state information and public relations department said all 35 primary contacts of the 15 NDRF personnel, who were diagnosed with the infection on July 4 and July 6 at Lungverh camp near Aizawl, have tested negative for the viral disease. COR RMS RMS
