Face coverings and physical distance are most important in preventing spread during transport, while ventilation, filtration, air circulation, and cleaning are also helpful.
Most of the transportation-related cases have originated from tourist buses, airplanes and cruise ships rather than public transportation, and occurred at the start of the pandemic.
Assistant Provincial Health Officer Dr Réka Gustafson said Monday, after announcing another spike in COVID-19 cases in British Columbia over the weekend, that while it may be difficult to To determine precisely whether the transmission took place by public transport, there are indications that this is not a major source.
The reason they can say this is that the vast majority of people infected with COVID-19 in British Columbia have been able to determine, after an investigation, where they were infected.
“Most of us don’t know who we were in transit with, and therefore if we thought that places like public transport and other areas where we have occasional contact with people were a major source of transmission, then the proportion of people who did not tell where they were infected would be much higher, ”said Gustafson.
One of the reasons for the lack of propagation on public transit is that policies such as mandatory mask wear, reduced vehicle capacity and increased cleaning are in place on the TransLink and BC Transit networks.
“If you add up the summary of the evidence, the totality of the evidence at the place of transmission, that doesn’t happen in places where people have security protocols in place,” Gustafson said.
