to follow us on twitter for all the latest headlines or handle there is the attitude of you news and you also get the latest on our website dot com thank you for watching. combating the corona pandemic. where does research stand. what are scientists learning. background information and. our corona up to. 19 special next on d w. y and on demand.
1:16 pm
language courses. the sun can give life but it can also destroy. the coronavirus may not be impervious to its power. a ray of hope in a beam of ultraviolet light it can help but it can also harm. scientists are working on ways to make it safer for people at a time when there's still no cure or vaccine for 19 can you feel light illuminating a way out of a global pandemic. big question welcome to night in special here
1:17 pm
until the news i want to jones and berlin good to have you with us now the case numbers are falling in europe but we don't know for sure if the warm weather is killing off the virus or if it's just taking a break we shouldn't take chances but we could learn from the sun and its powerful u.v. light. they start work when the shops close. it's safer if they don't come in direct contact with the staff or customers. these little robots are coronavirus assassins their weapon is you v.c. like. you always built one need knowing mean michigan missing facts so if you know of. a loss in f.l. couple of always free auto forms if you want dollars just where we know on the surface a kind of white bear. u.p.c. light can kill 99 percent of all pathogens in the air and is very effective at
1:18 pm
disinfecting surfaces. similar robots are being used in subways and buses like here in argentina. and little by little by little light is the light that the sun emits naturally and if the gustavus adolphus in this case we use type c. which is very high energy and works by destroying the d.n.a. of the bacteria. and they are in a in the case of viruses less avoiding propagation or spread out of. u.b.c. like kills all microorganisms but does not occur naturally. it has to be generated artificially. with the sun produces u.v. a b. and c. like this new light is filtered out by the earth's atmosphere otherwise there would be no life on earth. doctors advise
1:19 pm
against exposing yourself to direct u.v. c. light it's the most powerful level of ultraviolet light there is and it's especially dangerous for the skin and eyes. i don't know let's bring in dr told kroft she saved by religious at cambridge infectious diseases and into disciplinary research center at the university of cambridge good to have you with us. goodness stocks 1st of all looking at the virus itself what happens to a virus when it's exposed to u.b.c. . so the number of different chemicals and genocidal treatments can be used to try and disrupt viruses on surfaces and u.v. see specifically mutate the genetic material of viruses and it was. well when the virus genome is small us a few and that is in the genetic code and that typically applies to the new
1:20 pm
coronavirus cells called to you were just 30000 base has long i does the obvious even render the virus inactive if still alive or does it actually destroy it completely so it's rendering it active so incapable of infecting new cells incapable of causing new infections but if you looked for its genetic material on a surface after you and i would expect that you would still be able to find some of the genetic material that you just wouldn't be able to find infectious particles which is what we really care act right so in in this in this fight against the current pandemic how effective is u.v. sea when used against us co 2. this still only limited evidence of the usefulness of u.v. c. against sauce cost to you specifically it certainly can be used to deactivate to inactivate other similar viruses from the same current virus family but there are
1:21 pm
also risks associated with the c.e. treatment it's particularly talk sick to humans it cools cataracts it can cool skin cancer so there are there are costs and benefits associated with using u.v. c. for virus in activation right so what we saw in this report is that g.c. is mostly used like in bosses at night when they don't drown when there's no people in it but how big a chance do you saying there is a u.v. sea killing off the virus let's say in school classrooms as kids returning to schools offices shopping malls so all those enclosed places rooms those that actually were part of a dated os before the country make it easy is certainly one option that deactivating viruses owned surfaces and x. enclosed spaces one of the problems is that you require specialist equipment in this case specialist bolts to make the e.v.c. like that we need to be installed in all of these places you only get an activation
1:22 pm
of the virus on seth's is that it hit directly by the light so anything that's in the shape of another object would know how successful are killing so i think e.t.c. is only going to be worn tool alone saw it could last a cool classical options for killing the viruses on surfaces such as very good surface cleaning with with safe and water with ethanol or without perhaps hope disinfectants so you can see is part of the solution but it is not the solution in itself now of course we know that some coronaviruses a seasonal like the annual flu and indeed case numbers here in europe where someone is approaching you can feel it in the air off forming does this mean that size co 2 is also affected by warmth and sunlight. yes there's good evidence to show you that natural u.v. wavelengths that come from sunlight quite effective in activating the new coronavirus and a study was done simulating the amount of evie that you get the midday sun in spain in in the middle of the year around the time of year that we have now i'm sharing
1:23 pm
that midday sun in spain we did activate the virus on souces after at 7 minutes and at that kind of latitude even in december in bright sunlight he would see the virus and activated aftermath 15 minutes so we will find that even the some of this is less infectious viruses all the surfaces that we might be touching in the open air but actually it's likely that the the natural distancing that people are taking paulton during the summer is one of the most effective ways of stopping the spread of the virus will spread out more because when the outdoors there's that constant dilution of fresh air and that may actually be house powerful powerful than changes in u.v. or temperature right then we have to make the most off the summer months ahead and hope for a sunny wind to the whole cross from the university of cambridge thank you so much for your time thanks for having me. and it's time for your questions over to our science correspondent derrick williams.
1:24 pm
19 invades many but any fluids and opens is it possible for it to enter a fetus though there's still a lot we don't know about the virus and the field of reproductive medicine at this stage the chances of a mother passing it along to an unborn child appear to be very low in one study that looked at $38.00 expectant chinese mothers who became infected with cope at 19 none of the babies that were subsequently born tested positive for the virus from another that tracked 33 pregnant women in china confirmed that 3 of the babies born to them also tested positive for the disease but as all 3 were delivered by says syrian section it was unclear whether they caught it before during or after birth so even if the virus does cross the placenta in some cases it would seem to be

a pretty rare event. there are hot spots in the meat industry in the u.s. and germany is that because meat products can be contagious. workers at meat packing plants in many countries have been coming down with tobit 19 and in far greater numbers than the people who work in other industries so so what's going on now like so much about this disease it's still isn't isn't really clear but there are are plenty of guesses one involves proximity workers in meat packing plants spend a lot of time close to each other working fast and the work can be physically very taxing many people will be breathing hard it probably isn't easy to keep protective gear bike like masks in place and and social distancing is. very difficult the low
1:26 pm
temperatures in facilities also probably play a role the virus likely remains viable for longer at low temperatures experts therefore believe that the problem isn't that meat can carry the contagion but instead a whole range of of other issues surrounding this kind of work. pitch levels increase caring active pay if it $19.00 interesting least several studies have so far shown that it actually appears to be the opposite one that looked at blood work performed on nearly $600.00 patients discovered that not only does cholesterol in the blood sink in patients who have covert 19 how far it drops also seems to correlate with disease severity some experts even now believe limpid levels could be used to predict how badly someone is going to react to getting killed at 19 the question is why do those levels drop one theory
1:27 pm
is that cholesterol from the blood is being loaded into various tissues and and that's contributing in some way to the deadly progression of the disease that might for example explain why older people who start out with high levels of cholesterol are so much more affected than for example kids who generally have have low cholesterol levels it's an interesting working hypothesis i think but it's but it's still unproven. post your questions and derek on our you tube channel to keep you up with the latest developments on the grown up virus subscribe to our newsletter go to d.w. dot com slash corona dash us later. before we go it's not just disinfecting robots using alter violet light to gaining their place in the
