TRAGIC! Lady Infects Over 70 People With Coronavirus In Just One Minute
July. 13, 2020
A woman carrying coronavirus but not showing a single symptom took a 60-second trip in an elevator on her own and infected 71 people.
Coronavirus contact tracing experts were left baffled after the trail went cold as they tried to locate the source of an outbreak which spread across two hospitals in Heilongjiang Province, China in mid-April.
Details of the case have emerged in a new study released by the US Centres for Disease Control (CDC) which analysed the impact a single traveller with no symptoms can have.
The origins of the case can be traced back to April 2 when a man in Heilongjiang Province suffered a serious stroke – a known possible symptom of the disease – but hadn’t been diagnosed, news.com.au reports.
The man was rushed to hospital and his three sons took turns staying by the man’s side.
Between them, they unknowingly infected another 28 people including five nurses and a doctor.
Before being diagnosed, the man was taken to another hospital to recover from his stroke, where 20 more people became infected.
During this time, another man, known as Patient B, presented with Covid-19 symptoms and scientists discovered the strain had come from overseas.
All of Patient B's close contacts were tested and they also proved positive – one of them was the stroke victim.
Everyone the patient had been in contact with, or even close to while in the hospitals, was tested and put into lockdown but almost 50 of them had already contracted the virus, some had passed the virus on even further.
Contact tracers desperately tried to figure out how they had got the disease.
Patient B had met the stroke victim and his sons at a party on March 29, but nobody else who attended tested positive.
As the contagion was usually through close contact they tested the man's girlfriend and it urned out she had it, along with her daughter who she lived with.
The man had visited them on March 26 but neither the mum nor the daughter had travelled or had contacts who had travelled and no further cases of Covid-19 could be linked to them.
By April 9, the contact tracers were becoming desperate so they called up the profiles of everybody living in the same residential apartment tower as the earliest known sufferers.
One, they realised, had recently travelled from the United States – and she lived on the floor above the woman and her daughter.
A quick assessment revealed her to be well and she had been following self-isolation protocol but a swab revealed she had Covid-19 antibodies.
Detailed questioning and movement tracking showed the women had not come in direct contact with each other, which left just one possible source of contagion.
The lift that portion of the apartment block shared – the asymptomatic traveller had used it to get to the apartment where she had self-isolated.
“Therefore, we believe A0 (the traveller from the US) was an asymptomatic carrier and that B1.1 (the daughter) was infected by contact with surfaces in the elevator in the building where they both lived,” the researchers wrote.
“Our results illustrate how a single asymptomatic SARS-CoV-2 infection could result in widespread community transmission,” the study authors concluded.
Researchers believe the daughter who lived on the floor below must have touched her face, eyes or nose after later using the same buttons or leaning against the same panels.
They say their findings reinforce the importance of hand washing and isolating to prevent the spread of the coronavirus.
“Continued measures to protect, screen, and isolate infected persons are essential to mitigating and containing the COVID-19 pandemic,” the study reads
