China coronavirus deaths and cases spike - BBC News

China coronavirus deaths and cases spike - BBC News
the number of

coronavirus

cases

has sharply risen following changes in the way it's diagnosed the World Health Organization is seeking clarity from

China

after 15,000 more infections were recorded on Wednesday 254 more

deaths

have been confirmed that's more than double the previous Daily Record almost all of them are in who Bay Province almost 60,000 people in

China

are now known to be infected and the number of those killed stands at more than 1300 also officials in Vietnam have placed
china coronavirus deaths and cases spike   bbc news
the town of 10,000 people under quarantine following five

cases

of virus infection their Vietnam declared a public health emergency over the epidemic at the beginning of this month and in Japan a cruise ship the diamond princess remains quarantined in Yokohama after an outbreak of the virus on board it's now thought 218 passengers and crew members are among those infected our correspondent Rupert wingfield Hayes is in the port so the number of infections on board the diamond princess behind
me here in Yokohama has again jumped today 44 new

cases

confirmed today that followed 39

cases

yesterday and that brings the total number of infections from the ship to 218 and that means as we know now that this is now the single biggest outbreak of the Cova 19 virus anywhere outside mainland

China

the Japanese government has made a small concession to the criticism that has been building of its the way that its handling this outbreak they've said that very elderly people over the age of 80
will be allowed to disembark if they have underlying health conditions or if they are in one of those inside cabins that don't have any outside windows or balconies so expect to see that start happening maybe tonight or on Friday but there are many questions that remain first of all obviously is our infection still taking place is the virus still circulating around the ship no one really knows and the other big question is why still has the Japanese government not managed to test all of the
passengers and crew on board well let's get you some real expertise now David Heyman is a of infectious disease epidemiology at the London School of Hygiene and Tropical Medicine David previously directed the World Health Organization response to the SARS outbreak in 2003 David first I want to talk to you about the mortality rate the reports were seeing put the mortality rate of this virus at about two percent that's right and that would be at the level of influence of seasonal influenza
china coronavirus deaths and cases spike   bbc news
each year they're about one to two percent of people who died unfortunately but what's happened in

China

is the case definition that is the way they define a disease has included pneumonia and so they're missing all the less severe

cases

of disease and only looking at those that are most severe so of course the mortality is higher among those people so the case definition recently has been changed in

China

and they're now including less severe symptoms as well in their diagnosis
and something that's important now is the way they're testing it has been to do with these lab kits beforehand and and what's been the problem with those well they've been using test kits that detect nucleic acid the problem with them is that it takes a long time to get a result longer than they want it takes some times a day for them to get a result does it does it require some expertise to administer and and to read absolutely it requires both expertise and skill and and making
sure that there isn't contamination from the laboratory around it so what they've done recently is two things they've developed a more rapid point-of-use test for nucleic acid which they've rolled out it's not clear how effective this is but they're using it and in addition they've changed the way they diagnose and in some instances they're just diagnosing based on symptoms and an x-ray which means there's no nucleic acid diagnosis so does that mean the number
of diagnoses the number of confirmed

cases

is bound to jump absolutely because not only are they finding

cases

of

coronavirus

but they're finding other diseases that also are other infections rather that also cause pneumonia so they're seeing an increase in the number of

cases

and a decrease in what we call the specificity of diagnosis so what in in kind of real world terms David what does that this mean does it mean that just that the clinicians are able to spot

coronavirus

better or
china coronavirus deaths and cases spike   bbc news
that we should be alarmed the way in which it is spreading on the rate at which it's spreading well certainly it spread throughout

China

and

China

's making every effort they can in the way that they do best to stop the disease what's important though is those 24 sites outside of

China

and also the cruise ships that's where the information about how severe the disease is we really come from because the patients here are being monitored very closely as are their contacts and
we're learning a lot as we see what happens in these situations which hopefully will lock down the disease in these countries and not permit it to spread further is there an issue here in that

China

's obviously Communist Party state controls you know command and control to a certain extent for other countries not the case and it might be that there's less grip on the way centers are run the ability to to build the medical facilities as well well clearly in the SARS outbreak

China

had
the same type of a lockdown and they rapidly got rid of the infection in other countries where there was a different approach it sometimes recurred after they thought they had it controlled so there are benefits of authoritarianism but there are also disadvantages and the disadvantages of course are an infringement on human rights how would you describe your level of concern about the corona virus outbreak I think we're all concerned about what we don't know right we know so far
what's happening and what we can see but what we don't know is the real potential of this virus whether or not this eventually could become a disease endemic in humans like TB influenza or others because influenza also comes from animals into humans and it sometimes becomes a permanent resident David Heyman really appreciate you coming in today thank you very much thank you
