Guwahati/Kohima, The return of thousands of homebound people from southern and western India to the Northeast caused an abrupt rise in COVID-19 positive cases in the region, especially in Assam, where 168 fresh corona patients were reported in 24-hours taking the total count to 595 on Tuesday afternoon, ministers and officials said on Tuesday.

Assam Health Minister Himanta Biswa Sarma in a series of tweets said that of the 595 positive cases till Tuesday afternoon, 526 are active cases, 62 were discharged from the hospitals, four died and three migrated to other states.

Sarma said that 90 per cent of the Covid-19 patients in the state have been reported from the quarantine centres across the state's 33 districts. However, health officials said that there are positive cases found in some districts outside the quarantine centres.

He said in Guwahati that the sudden rise in corona cases is due to the return of 60,000 people, mostly from southern and western India, to Assam after the Home Ministry withdrew the interstate transport restriction on May 4.

Meanwhile, two more persons who escaped from the Don Bosco School quarantine centre at Ramnagar in Silchar in south Assam were apprehended by the police at Algapur Railway Station on Monday night. Earlier three patients had fled from a quarantine centre in Guwahati. Police subsequently arrested them. Poor quality of food and other difficulties are said to be the reasons behind the escape of people from the quarantine centres.
