will do what you want time for your questions now over to our science correspondent and that's derek williams. does sars kovi to incorporate genetic material into your d.n.a. that remains even when the disease is passed. the number of different viruses among for example hiv or herpes viruses use a variety of different methods to incorporate their own genetic material into that of the cells that they invade in fact a substantial portion of human d.n.a. we think around 8 percent isn't strictly speaking human in origin it's genetic information from by risk is that integrated into the human genome at some point in the far distant past and has been hanging around in our genetic code ever sense which is kind of freaky when you think about it i mean it's thought that these sequences might be involved actually in a wide range of what we consider to be non infectious diseases like cancer or or dementia but sars cove too isn't the kind of virus that replicates by integrating into our genome it doesn't have to invade the cell nucleus where our d.n.a. is it can find everything that it needs to make more

and now it's time for your question here is our science correspondent derek williams. a mother who is a symptomatic breastfeeding. it must be terrifying for the mother of an infant to test positive for a covert 19 whether she displays symptoms or not because the relationship is such an intimate one physically that it seems highly unlikely that the baby won't contracts the disease as well despite the threat though both the w.h.o. and most national health authorities urge mothers who have tested positive for the disease whether they're symptomatic or not to continue to breast feed because the benefits of breastfeeding and skin to skin contact between mother and child a substantially outweigh any risks associated with coated 19 for the child so it still isn't 100 percent certain that breast milk always remains completely free from the virus but but the evidence indicates that it's not really spread that way the mothers who test positive should however follow a list of precautions to try to prevent passing the virus along to their baby if this is an issue for you i recomme

here questions now anderson's correspondent derek williams. can you tell us more about decks and methods. decks and methods own is one of the drugs that doctors now prescribe at that critical stage of covert 19 that i just mentioned when the immune system has gone into overdrive and starts attacking healthy tissue and the body a major study in britain that's still in peer review discovered that in critically ill patients who need respiratory support the compounds lowers mortality by between a 5th and and a 3rd which is actually pretty huge that's a meth is known as what's known as a corticosteroid and it's widely used to treat many different conditions that cause painful or dangerous inflammation it's also and immuno suppressant so it can help calm down the immune system when it's running a mock but that also makes doctors wary about about giving patients the drug too early when the immune system needs to be active it's not a new drug but one that's been approved for use for well over 50 years now so so it's cheap it's widely available and per

more aspects to this pandemic and it's time for your questions now is our science correspondent derek williams. who vaccines work for young children or be tailored for adults. this question addresses one of the reasons why it's a good thing to have so many different teams working on on so many different vaccines there's a widely acknowledged problem with testing not only vaccines but but new therapies in general which is that early trials in particular are usually conducted on groups of healthy adults under $65.00 and of course they aren't the people who need it most with covered 19 elderly men with co-morbidities are the group that's most at risk but especially in early safety and efficiency trials nobody will be trying vaccine candidates out on backwards because not only could it be dangerous it could also skew the data and lead researchers to false conclusions the same holds true for testing new vaccines in children it can be risky because you can't just treat them. like little adults they they can react differently to vaccines it's certainly possible this is not likely that children and ad
