It comes amid a new development in the quest for more streamline testing for the virus. Heres abcs matt gutman. Reporter its an issue that has seemingly come to epitomize the nations chaotic, late response to covid19. So the current test thats been available up to this point has been very manual or labor intensive. So that has hindered how quickly we can turn results around and the volume of tests that can be done. Reporter but this weekend we may have turned a corner. The fda approved a new test for the virus. We did this within hours after receiving the application from roche. Reporter roche molecular solutions, a private Health Care Firm which the fda says is the first commercially distributed test to receive emergency authorization. Its a breakthrough because it speeds up the testing. What we can now expect is that were going to provide 400,000 tests in the coming days. So that will mean that we will make available about 1. 5 million tests every month. Reporter how did roche pull it off . This footage was shared only with abc news of their teams working round the clock across the world. The test developed in just seven weeks. The challenge was the timeline. Could we do it in six to seven weeks as we were being asked to do . We did something that usually takes 12 to 18 months. So we had to reinvent how we did things. Its really breathtaking. Reporter with the potential to have a Significant Impact on covid19 testing, the roche factory went into overdrive.

Little theos nose had cause for alarm. His ordinary tissues were causing it harm. They left his nose raw, with each wiping motion. Hd 5. A nose in need deserves puffs indeed. As we reported minutes ago, theres troubling news out of france, projecting that half of as we reported minutes ago, theres troubling news out of france, projecting that half of the countrys crit as we reported minutes ago, theres troubling news out of france, projecting that half of the countrys critical coronavirus cases may be people under the age of 60. Abcs david muir spoke with the nations top expert of Infectious Diseases about younger patients. Things are definitely going to get worse before they get better. If you look at the pattern of the outbreak as it hit Different Countries and different cities within countries, and i talk specifically about china, about south korea, and most recently italy, what happens is that you putter along with cases, a few, then you reach a point of inflexion, where it takes off. If you look back at the history of outbreaks, you get this big, big peak. Then it starts to come down. If you leave the virus to its own devices without trying to interfere with it. We have the opportunity now, even though we will still continue to see an acceleration of cases, we have the opportunity to blunt that peak and essentially make it more of a mound, which would mean less sick people and less death. But thats not going to happen spontaneously. I wanted to ask you before you go about the reports out of france over the weekend of the hundreds in Critical Condition, potentially, they reported half could be under 60. What does that tell you, and perhaps more importantly, what do you know right now about who has this right now in the u. S. , what the demographics are . What are you seeing in americans right now . Well, its not well, the number in america is still low. But were seeing the patterns that we saw in china and that we saw in south korea, which is that if you look at the people who get into trouble, they are overwhelmingly weighted towards individuals who are elderly and individuals who have underlying conditions that compromise their ability to fight the infection, like Heart Disease and lung disease. You will always see outliers of individuals who are otherwise young and well, who wind up getting into trouble, getting seriously ill, and even dying. Im very interested in them, we want to follow up on those reports from france that say that there are several people. When i heard that, i called up some of my colleagues, some of whom i trained years ago in my own group in italy, and i said, im hearing this about france, what are you seeing in italy . Italy admitted, we are seeing a few people, a minor proportion, but they certainly are there, of younger people, in their 40s and 50s, who are getting seriously ill. But he confirmed that the overwhelming majority of the people who get into trouble, the average age of the people who really get sick and die is 80 something years old. Our thanks to david there, and dr. Fauci, who says again, there will be millions of tests in the coming weeks and people, they really want to know that timeline, zohreen, because as we mentioned, time is of the essence.
