The samples would be tested using the polymerase chain reaction (PCR) method to get a more reliable result.Although faster and more affordable compared to the PCR, the rapid testing is deemed less accurate in detecting COVID-19 as it only detects antibodies against the coronavirus in blood samples. He went on to say that authorities would need several days to complete surveillance and contact tracing, as the team had to examine many more students.The surveillance would focus on students living in the same housing complex where the 43 Malaysian students lived. The complex, located within the pesantren, was occupied mostly by foreign students.Al Fatah, located about 11 kilometers north of the center of Magetan, has more than 22,000 students; 2,000 of which are foreigners, mostly from Southeast Asian countries.The boarding school is also known as the base for an Islamic group known as Jamaah Tabligh, which has held events in Malaysia, India and South Sulawesi that have been linked to several COVID-19 cases in the respective regions. It is unclear whether any Al Fatah santri attended those events.Kohar said authorities expected more students to test positive as examination and contact tracing was still under way.Read also: In shadow of coronavirus, Muslims face a Ramadan like never beforeMagetan Regent Suprawoto told The Jakarta Post on Thursday that the Malaysian government had urged the remaining Malaysian students to return home, although they initially wanted to stay and spend Ramadan in the village.Officials from the Malaysian Embassy in Jakarta were preparing the necessary documents so the students could return to their home country as soon as possible, he went on to say.“However, we want those who tested positive during the rapid testing to stay and undergo treatment here in Magetan, while waiting for their PCR test result,” said Suprawoto.East Java has recorded 664 COVID-19 cases as of Thursday, with 60 fatalities and 112 recoveries.

They also put the village under quarantine, restricting people from entering and leaving the village.“I had to wear full personal protective equipment upon briefing the santri and other residents in the pesantren, because I know the area is a severe red zone with high virus transmission,” said Kohar Hari Santoso, an official from the East Java COVID-19 task force.
