At least 52 people from a single flight from Delhi to Hong Kong have tested positive for Covid-19, despite all passengers presenting a negative coronavirus test before boarding.
All of the passengers who tested positive flew into Hong Kong on a flight from India's capital, run by Indian airline Vistara on April 4.
Hong Kong as a whole has been recording fewer daily new infections than the total number detected on the flight, since it brought a fourth wave of infections under control in January.
Meanwhile in India, the country's healthcare system is collapsing under a devastating second wave of coronavirus that is killing more than 2,800 people a day in the nation that is home to 1.3 billion people.
A total of 188 passengers could have been on-board the flight, but Hong Kong authorities did not disclose how many people were on the plane.

Aircraft Cabin Air Recirculation and Symptoms of the Common Cold
ReplyDelete"In recent years, new commercial aircraft have been designed to recirculate approximately 50% of the cabin air to increase fuel efficiency. Some older aircraft use only fresh air. Whether air recirculation increases the transmission of infectious disease is unknown; some studies have demonstrated higher rates of the common cold among persons working in buildings that recirculate air."
"The false-negative rate for SARS-CoV-2 RT-PCR testing is highly variable: highest within the first 5 days after exposure (up to 67%), and lowest on day 8 after exposure (21%)."
Improve the energy star standards, so 75% of the air is recirculated or 90%. Help those false negatives spread the the love.
Probably not acquired on the plane unless the filters are screwed up.
ReplyDeleteTests not working or not done right. Instant tests are useless.

ReplyDeleteWhy don't soldiers only use HEPA filters against biological warfare agents?
Using a test to determine viral load and when(?) they were infected with the cluster and questionaire, look at the bathrooms? Masks have been determined to be merely theatrical.
