@NealBrowning According to the industry tests early in the pandemic, the risk of being infected by someone with covid near you in the plane with perfect masking is 2% per hour with less infectious strains. It might be 6% per hour now. If 2h flight, about 4 infected, more if masking poor.
@NealBrowning根据大流行早期的行业测试，在飞机上被你身边的人感染的风险为每小时2%，而感染性较低。现在可能是每小时6%。若飞行2小时，约4人感染，若掩蔽力差则更多。
