of the lightness institute for prevention research and epidemiology thanks for your analysis. thank you. now you got to ask the questions here's our science correspondent derrick williams. i've heard research is talk about trying to mute the immune response but also saying that a young stronger immune system is more successful in fighting off 19 it's not a contradiction. to understand the apparent contradiction here you have to understand that there are are different stages of covert 19 that patients can go through the 1st is usually an initial infection in the upper respiratory tract and that's usually where it stays with most people that's where having a strong fast acting immune system is really great it's able to keep the disease in check and eventually wipe it out in some cases it keeps it so effectively in check that you might not even notice that you had it but in more severe forms of the disease if the virus eventually makes it to the loans or to other organs it can kick in a severe immune response and when that happens the immune system can start attacking not just dis

professor hired saved of the life in its institute for prevention research in epidemiology a joins us now professor at save you've written about how the risks and consequences of this pandemic are an evenly distributed socio economically speaking we've seen in this report how especially vulnerable migrants are and at so many countries depend on migrant labor from around the world what can be done to protect them so 1st of all i think we have to basically respect their contribution to all you know economy to society and so or so that means. help them to be able to cope with their demick just as many countries try to do for the citizens living in the country anyway so that means inform that person or allow them help them to you know take those protective measures that are needed improve working conditions such that distancing is possible and sure that their living conditions are ok mike and rocha's often live on their very precarious conditions it crowd its accommodations and these other things that we can really do in our own to support those communities that make sure that they can re

professor for gender sensitive prevention research have to focus is on how men and women can prevent age related conditions like obesity and diabetes and how doctors can best support them in their efforts. look at. the point is for people to eat healthier get more exercise reduce their tobacco and alcohol consumption and then live longer and healthier and with a decent quality of life. but there are all significant differences between the sexes women tend to know more about what they're eating and have healthier diet many generally know more about exercise and do more sports. those insights can help improve self-help options such as for losing weight. from common good. women are ok with group activities such as those offered commercially but men not so much. there are receptive to on line options. so tailoring things to what men and women need will hopefully increase people's interest in the measures and mean a better chance of success. or. further issues dealing with serious diseases such as cancer something women will talk about with their friends men on the other hand can find in

this has essentially prevented researchers from being able to enroll patients in clinical trials of convalescentsma. why is that? well, if you are a patient who is being offered the option while you're dying, you're close to death's door. you could either get this treatment that may or may not work, through the emergency-use authorization. or you could enroll in a clinical trial, and maybe you'll get the plasma. maybe, you'll get placebo. that becomes a very emotional decision. and i can guarantee you that decision is not going to be made, 99 times out of 100, to enroll in the trial. so, what you've done is you've slowed down enrollment in studies that will actually give us data on if this works. so this is operation slowdown. this is not operation warp speed. >> uh-huh. so, this is the new guidance from the world health organization. kids who are 5 years old and under should not wear masks. and kids who are over the age of 12 should wear masks. so the school year's just beginning. and -- and this guidance. what is this? it just keeps changing., i thin those youngest kids, we still don't have a

a william schaffner works in preventive medicine and infectious diseases just how infectious is the corona virus when according to the latest research well it certainly can be transmitted by the born route at some distance we still think last of the infections are transmitted indoors within 6 feet but there's no doubt now those airborne particles can travel more widely at a greater distance particularly if you have someone who is a super spreader and is shedding large amounts of virus so both close in and farther out contribute to transmission this is a very contagious virus who in this case is a supervisor someone who's not wearing a mosque. almost certainly someone who's not wearing a mask just masks are very effective in in blocking transmission out and of course that's why the recommendation is here in the united states at least that all of us should be wearing masks when ever we are around other people but what would you say to the guys at my gym who refuse to wear mosques some of my colleagues even and people out there who just say they have a right not to wear a mosque. well it's very difficult to persuade people who are very
