Could you give us your thoughts, and perhaps we don't know the answer to this yet about the estimates you've seen or the talk around the fatality rate here, because how different is the fatality rate that we're seeing so far to what we see with normal seasonal flu? Just trying to get our heads around the the size and the impact of this virus, so the virus is a different virus to what causes influe ...
za to start with. So the the what they're seeing is a case fatality rate. So that's the number of deaths per confirmed cases of about three percent, which is higher than would be seen for influenza, but there may be a number of people who are that. What we don't know is the number of people who are infected. That may be not symptomatic or not going to hospital, so so there there may be a larger number of individuals who are infected and yet not with without symptoms. Right we've heard or i've read that the symptoms don't really show until two weeks after an individual has contracted the virus, and i wonder, is it contagious then, before the symptoms show doctor i mean, is it possible that people who don't seem to have any kind of Illness are already out there spreading the virus. It'S not known for this virus. I think what we know for sars coronavirus, which is a related virus, was that it spread after people were symptomatic, and that made the control of the infections rather somewhat easier. We do know for other infections such as influenza that people can spread the infections provider to being symptomatic, and that makes the control measures harder. So we don't know for sure with this virus, yet whether it can spread a symptom. I thought spread prior to symptoms. What can you tell us about vaccines and at the time that they normally take to be developed? Any progress that's being made to develop one that will could be used with regards to this virus? So there's been a big push to develop to rapidly develop vaccines.

For for this virus and organizations such as imperial college and organization called sepi are developing a number of parallel vaccine approaches. It looks like we, the organisation's developing vaccines, may have the first inhuman vaccine trials done by the summer. This is because the it takes time to manufacture sufficiently safe vaccine material to put into people, and then it needs to be tested for safety before it can be tested for whether it protects against people, so that it is an accelerated program compared to what might be Seen for other infections, but it still will not be online for four or five six months. So that's a long time. What do we know about the the rate of the spread of this virus? Then doctor i mean last week we were reporting on a few hundred cases, now we're reporting on a few thousand cases. If you extrapolate that out to the time when a vaccine is ready or some kind of medicine, i believe with sars, there was actually an antibiotic that was quickly released. How many cases could we see before there's some kind of treatment say a with the vaccine? A vaccine won't be in place for a foreign for a certainly for a several months. So what needs to get into place is effective control measures, and this includes simple things. Such as hand-washing and limiting contact between people and the efforts the chinese governments are going to do to control the spread of disease is very important in reducing that kind of number of cases there may be. There are certainly drug trials going ahead with drugs that specifically target viruses, and so those drugs may reduce the infection and the number of cases and those trials are ongoing. But these need to be developed with obviously carefully and with due consideration of the ethics of doing clinical trials in such a kind of ongoing academic. You mentioned the around three percent cfr case were the the case, fatality rate john, which you said, was higher than influenza.

What do we know about those who have died so far whether there have been underlying a pre-existing health conditions that have meant that was more likely to happen? What can what can you tell us about that? From from what i've seen, it looks like the case, the the deaths of appear to be in people who may be out a more old sub, sorry, elderly and say. Maybe the age is an increased risk factor for fatality, but i it's difficult to find food eats in such a rapidly moving situation. It'S difficult to find all the details as to what's going on what is the underlying conditions in these cases?.
