A traveler isolated for COVID-19 in a New Zealand quarantine facility infected three other people across the corridor, the researchers said. CCTV footage and genetic testing showed that the only way the virus could spread was through air that moved between rooms on the same floor when doors were opened at the same time.
- In many countries of the world, there are special centers where travelers have compulsory quarantine
- In one such location in New Zealand, a Filipino traveler infected three other people, even though they were on the other side of the corridor and had no contact with him.
- From the group of quarantined travelers, only one person remained uninfected – the only one who was vaccinated against COVID-19

Andrew Fox-Lewis from Auckland, New Zealand and his colleagues reported in the journal Emerging Infectious Diseases a case of SARS-CoV-2 infection among people in quarantine.
Two groups of travelers arrived in New Zealand at the same time. A Filipino traveler tested positive and was placed in a temporary quarantine facility. A group of five people came from the United Arab Emirates and they were also quarantined because one of the group members tested positive. They were placed in the same facility as the Filipino traveler, across the corridor.
No one was allowed to leave the room. The door was to be opened only for food deliveries and testing, but never at the same time. But «The camera footage revealed four short episodes of opening the doors to both rooms at the same time during the infectious period of person A, that is, a traveler from the Philippines »- describes the Andrew Fox-Lewis syndrome. “It only took a few seconds each time.”
It does it only took three more people out of a group of five to become infected. Most significantly, genetic testing of the virus revealed that the source of the infection for three people was a Filipino traveler and not a room mate.
SARS-CoV-2 migrates extremely quickly by air
Scientists say aerial transmission through the corridor is the most likely explanation. “These findings are of global importance for public health interventions and coronavirus infection control,” wrote New Zealand researchers.
«Our discoveries support the hypothesis that during episodes of simultaneous opening of the door, particles floating in the air in the room of persons A quickly moved to the rooms of the BCDEF group” – added.
One person avoided infection – how is this possible?
The researchers emphasized that the only person in a group of five to avoid infection was vaccinated. «Despite sharing a room with four other test-confirmed people with SARS-CoV-2 infection, person F did not pass the test. The person received two doses of the Pfizer-BioNTech vaccine. No other group member was vaccinated ”.
Earlier, a team of Hong Kong researchers reported that a fully vaccinated traveler infected with the Omikron variant infected another in a quarantined hotel. The infection also occurred despite people staying in separate rooms of the same hotel.
