Sure, and a lot of misleading stuff is true.
Consider this imaginary scenario. Imagine a dead body is found in the street in front of your house. The dead person has multiple stab wounds, and there is a knife 20 feet away from the body.
Imagine you inform the police, but they come 2 hours later, and announce that they'll investigate the death. Then 2 days later they come and announce that they had no evidence that this was a murder. They also announced that staying in and locking your doors had shown to not stop serial killers and was counter productive.
Do you want such an investigative agency?
I would prefer if the police said something like this within 1 hours of arriving at the crime scene "the stab wound and a bloody knife indicate that this might be a murder. In order to stay safe, the residents should stay in, take precautions and lock their doors"
In case you didn't get what I referred to, there is no reason to doubt via a SARS like virus with respiratory sickness may be transmitted via air. Their default reaction should have been to assume the worst. Further, saying that travel restrictions do not stop a disease is a stupid statement to make. Specially when we see South Korea, Taiwan, Vietnam, Hong Kong, NZ etc exterminate the virus.
WHO is to blame as much as individual governments.
