I hear three questions and they're all excellent.
In terms of pregnant women, as Matt said, we're doing all of the testing in Canada right now, both for the presence of the active virus in the blood and for antibodies towards the virus. The latter test is tough to interpret. It's very difficult to interpret, and we're suggesting that the doctor be aware of that and that they have a good conversation with their patient, either before or after that test.
Oftentimes, we don't know whether the sample is coming from a pregnant woman or not. We're aware of one in Canada at this time. There may be more, but we're not aware of them. Obviously, for confidentiality reasons, we're not indicating where this person is. It would be much too easy to identify them. But that's all we're aware of.
We expect the numbers will increase. Given the three million travellers, we expect we'll see a lot more people who are positive for that, hopefully not pregnant women but we'll see a lot more.
Regarding your question about whether it's contagious, no, you can't sneeze and that. The methods of transmission are limited to—and this is our scientific knowledge now—those two mosquito types.... The virus is in the mosquitoes, and they'd have to bite a person who is uninfected and inject that into them. There's also sexual transmission through semen. The virus is in the semen of a man who's been infected, and it lasts for up to two weeks after the infection onset. Rarely, as my colleagues were saying, there are a couple of cases involving blood transfusion in Brazil.
I'll pass that over to you.
