and now is your chance to ask the questions to our science correspondent derrick williams. when will this pandemic be over. you know that's the trillion dollar question isn't it i wish i could answer it but right now no one can the w.h.o. has broken influenza pandemics down into 6 stages and they're only considered over when levels of flu have returned to stable a prepare endemic levels but what if the definition of an end to the covert 19 pandemic means reaching a stable number of infections worldwide then we still have a very long way to go in the absence of measures like social distancing the number of new infections will only stabilize with the advent of herd immunity when an estimated 60 to 70 percent of the earth's population has been infected and recover . but a huge vaccination program with a highly effective vaccine would of course accelerate that process so while we can say that this pandemic too will certainly one day ends there is still way too many factors in play for anyone to say exactly when that day will be. is there a chance a vaccine could cause the virus

i was going to derrick williams there i've been fizzling thanks for joining us at all so you get very sick here on the deal with about. what do you actually like to. taste different. there are always new nutrition trying. to spite of all differences are there any nutritional facts that apply to everyone. what should you pay special attention to so how complicated is the good nutrition. good. next to. this is some hope story a stubborn rice farmer from thailand. his problem. is crito no chemicals. his wife thought it was crazy. and i bought ducks. and. step. by step no. longer. stand a chance. the racists rising the farmers free. the final stage production to top it off. running. training successful. structure. starts july 27th on c.w. . welcome to in good shape coming up. dietary fiber and its many benefits for health. tick bite can trigger an allergy to meat. and.

now more of your questions now correspond to derrick williams and standing by to delve into the world of medical science. assuming different couvade 19 vaccines are successful on different timelines what is the possibility there will be multiple vaccines available within a certain country. the chances are are quite high actually there are over 150 different back scene trials going on around the world and over 30 of them are already in human trials a few of them quite far advanced down the road to approval they're also based on a number of different platform technologies which will play a role in the crucial step of production when and if they're shown to be effective on a wide scale what are known as messenger r.n.a. vaccines would be quite fast to produce but the technology is still pretty cutting edge it's so new that that if an m.r.i. on a vaccine is approved for covert 19 it would be the 1st m.r.i. and a vaccine to be approved ever for for a disease more tried and tested technologies that rely on small or inactivated doses of a pathogen or more proteins that it carries they take l

and now it's your chance to ask the questions is asked science correspondent derrick williams. what's the d.c. 614 g. mutation. the d 614 gene mutation is a mutation in a variant of the virus that's predominantly found in europe and most of the u.s. and there's been lots of speculation it might be links to either higher fatalities or or higher transmissibility in patients one study from the us that still under peer review claims to show the mutation makes the virus much more infectious by by stabilizing and increasing its number of spy attacks though those are those proteins that sorry to use is to attach to cells but those researchers were only working with cell cultures so so their results don't necessarily translate one to one in the real world though other studies have supported the idea that the 614 g. variant is more transmissible it'll take more work to find out if the mutation really does make it more infectious in us rather than just in our cells and culture . why is covert 19 considered a pandemic when less than one percent of the world's population has been infected.

and now your chance to ask the questions is out science correspondent derrick williams with some of the issues you guys have been raising with us. can you tell us about the vaccine russia claims it has produced. over $150.00 vaccine candidates are under development worldwide at the moment and 4 of them are currently in what's called phase 3 testing that's when a candidate has been proven safe so it can be given to thousands of people in wide scale trials to see how effective it is at preventing them from contracting covert 19 now last week the director of a russian institute announced that after positive results from small scale trials it would also go into wide scale testing with its candidate sometime in mid august that candidate is what's known as an ad no viral based vaccine that's a platform that's been around for decades the method works by modifying another virus called an ad no virus to deliver the genes that in code for proteins found in the spikes that dot the surface of sars code to that it's hoped will train the body to recognise and fight off the new corona virus in the fut

and next up is derrick williams he's our science correspondent and has been hard at work answering your questions about coven 19 here's our latest installment. of any researches tried i haven't. talked about this a couple of months ago but in light of recent developments i thought it would be good to discuss it again health officials in some countries particularly in south america have been promoting the anti parasitic drug ivermectin as a treatment for covert 19 and people have been buying up supplies of it even though there is no solid evidence that the medication works against the new corona virus ivermectin it is however a very effective treatment for infestations of of nasty things like like lice and pen morgan's. one big problem now is that with stocks of the drugs used to treat humans depleted people are beginning to self dosed with versions of the drug that are usually prescribed for animals now it should be obvious why that's a very bad idea there are human trials going on and at least one has been concluded but the 1st results don't really look very convincing until we know a

assads correspondent derrick williams there i've been fizzling thanks for joining us at all see you again very soon there on the delta about. drugs weapons human trafficking khandelwal to a no near naples where the nigerian mafia is on the riots. how's it it comes to this who is behind it is someone holding. a meeting inside to see how business there is really focus on europe. on t w. to the point sean opinions clear positions international perspectives. after 4 nights of heated negotiations the leaders reached agreement on the $750000000000.00 euro recovery package it's being hailed as historic in principle will it prove so in practice find out onto the porch. to the point. of being 16 years on t w. o. 4 or clusters from nigeria we are as a people here does what normally would stand still their unique. queen for knowing. often during. the tour fast moving down a long. and successful beyond belief. in other words this is the way we do it. we would start. on you. hello and welcome to focus on here oh thanks for joining us today look around the crisis has overshadowed many important issues

i'm to visit derrick williams in his home office we've had our science correspondent looked up there since the beginning of the crisis researching your questions on the crow virus. is reinfection possible. research on this topic while ongoing is is still inconclusive and will likely continue to be so for some months to come but a certain amount of what's called outlier reinfection with covert 19 is actually to be expected not not everyone who catches the virus will mount a strong immune response and we know that repeat infections do occur with other coronaviruses there are also a number of reasons why someone who tests positive once for an infectious disease can really test positive a few months after their symptoms improve including the chance that they never really shook off the infection the 1st time around i think the key question here is not about whether reinfection can happen it's about it's about scale if we started to see significant numbers of people who had copd $1000.00 once beginning to come down with it again then that'll be the time to really worry but but up until now

it's the part of the program where you get to ask the questions as our science correspondent derrick williams. can kovac 19 cause bad breath. ptosis can be caused by a wide range of different factors from inadequate dental hygiene to to a more serious underlying condition but the w.h.o. doesn't list it as a symptom for covert 19 however there is an interesting connection between bad breath and the virus mouthwash sales have spiked during the pandemic which i guess was to be expected i mean plenty of people probably hope that using mouthwash is regularly will have a preventative effect even though there is currently no evidence that that garbling with them protects you either that or or breathing into a mask all the time has made people hyper aware of how their own breath smells. can you catch coded 19 from drinking unfiltered tap water. there is no evidence you can get covert 19 from drinking treated water and the risk of transmission through water in general or even untreated wastewater appears to be very low even when the viruses genetic material can be detected in untreated water in most c
