tonight on ed newsroom. ru coronavis cases are on the rise. there are more infections among younger people. extract challenges facing the san francisco zoo and the oakland zoo. the animals still need feeding . >> scientists are cordaboring across s to fight covid- 19. we spoke to researchers in california and in bolivia about >> good evening. solutions . public health officials hoped to see fewer ronavirus cases since it is summer. instead, the cases are on th rise. it is across the globe, across the nation and in california. senior citizens seem to be the hardest hit. now younger people are making

up the larger number of people falling ill. since the beginning of july 65% of the cases are between the ages of 18 and 49. joining me by skype isdr. domingo. thank you for joining us. >> reporter: thank you. the age of affection is d droppistically. why is this? is it related to topening? t is a great question. we see the average age of earlier in the pandemic was 65 . years now some reports are as low as 35 years old. we have seen the shift, it has gone down word. there are probably two ways think about this.

we asked older people to stay home. we said you are more skat for this type of infection. what we reopen people did stay home. it was the younger peoplethat went out. they probably did two types of things, they worked, that is what we asked them to do. they also had a good two time. the reason why the younger people, they arthe people we said you can go out and help us to reopen the economy. that is why they are at risk now. reporter: you enforce the otection. the younger people are not getting as sick as people that are der. they at dying at the same rate. does this mean if you are younger, you do not need to worry? >> an important ssage is at

every age, everyone can beed infeith the virus. at every age, they have the possibility of having severe course. that includes assevere course that may lead to death. we have seen death and we have seen severecases in younger people. they do not occur as commonly as older people. here's the numbers game. we have many more cases in younger people, weare also seeing that some fraction of them are ending up in the hospital. some, i believe may have more severe outcomes. it is important to know in california even though the caseopare in younger we are seeing a rise in hospitalizations. we also, i think we are seeing are rise in death. >> reporter: dating this is the worst it's going to get in california? >> this is why i am optimistic ony we have be cautious.

i am optimistic is because california was great at the beginning of the pandemic. we were great in th bay area by shutting down the economy. we sheltered in place. we paid attention to all of those things. attening the curve. good at the problem is shutting down was easy but opening up is hard. it is hard because we need to do ort. that includes wearing a mask and the other things that we have tdo. we havto pay cle attention. right now we are in the mist of an uptick of cases. we are in a delicate and dangerous time. redouble our efforts to get this under control. >> reporter: once we reopened it we would see more new cases. by this time hospitals would be able to manage more cases.

why are retrenching in closing >> that a great quesaron. y? yocorrect. part of this is we do not want to have an overload of cases in happened in new york. even though we have had an attack! uptick in hospitalizations, we are not at the critical point. we ha been abto redistribute across the state of california. we expected to see an uptick in cases but not nearly the rate of rise thse we are ng now. we have a positivity break, the number of tests that are rise across the one you. it is definitely in the danger zone. that is concerning and we do have to pay attention. i would say two things that we did not do as well. one thg is we fail to realize as we went outside we had to treat the protections thwe

got from sheltering in place from protection that we needed in public. the universal masking when you're out. the second area, this is something we are starting to appreciate even or more is how inenvironments really are where there is great risk. we have seen this in the retrenchment in taki that there were we can dine indoors. closing the ba, also it important to make sure that gatherings in someone's home or another private, indoor environmt is limited to smaller number of peopev. i besanta clara just banned those types of indoor gatherings. indoor environments are particularly challenging. are learning from the world alth organization is ththe virus will stay in the air. ro

in closed enents, especially when you have the mask off because you're eating environment. hat is a risky thwhat you are seeing by the move of most of our ning. es to take back indoor >> reporter: i want to turn to testing. you have been involved in g correlate testing in different locations. there was a very specific test in the mission, there will be another one in oakland. why is testing still scarce? whthe resources not available as they should be>> alifornia has done a great job of making the test available. what we see is a mismatch of whhee testing is we know in the bay area and across california that the latin communithas been hit very hard with this virus.

the african-american community has also been hit. what we ve seen is that it is important to take testing to their communities affected. there was fear about testing. sometimes there is concern about the cost of testing. there is fear contact tracing and other people being involved. what we have done it many the studies in the mission, and also in the bayview district, what we hope to do in oakland is testing in s,the communit in the community fair type of at will bring people out. we work in partnership with community based organization to build trust and to make sure we are following up with the people that have tested positive. that is a barrier thle leaves ú>> reporter: in the last few minutes if you were to shape your cstal ball what the scenario that you see playing

out over the next three months? do you think the schools will reopen? >> i think in the next three months, if i look at california i feel optimistic we are stayed that will where we can get back to where we were the beginning of the pandemic if we understand and help all of us, this will require the leaders and everyo that lives california to do their part to get us under control. then i think we will have to reevaluate the state of the science, also the state of what our resources are, can we reopened the school safely? can we reopen colleges and universities safely eight? if businesseare reopening how to ensure the workers, including the low-wage essential workers are safe when they are there. if we can get that we can get e back to we were here >> reporter: thank you so much dr. domingo . >> thank you. let's turn to to long-

standing bay institution. the california dues have been permitted to reop. the oakland zoo and the san francisco zoo bothmain close. behind the scenes the zoos continue to care for the animals and maintain the grounds. but the lack of visitors has been addressed a call in th budget. does zeus have received money from the paycheck protection program. the money is running out. possibility of closing forever. joining me by skype is the ceo. we also have the ceo of the san francisco zo>> tanya peterson. hank you . reporter: the san francisco botanical garden d over 20,000 visitors. why is there a difference between the botanical garden and the zoo? >> i do not see a difference

especially with the reopening plan. all outdoor places will be open. i thinwe can opensafely with less people d in a controlled >>manner. eporter: tell me in a nutshell how bad is the financial picture for the oakland zoo? >> it is a matter of numbers. by the end of this month we will have to $.2 million left the reserve. we have earned $1 million per month. we will e up the rese: es. >> reportwhat about you dr. peterson? how is your financial picture? >> we are just a coupleof months behind. we have not had to use the rserve thanks to the communit and jor donors. i think there's a frustration from our donors and our

members. >> reporter: what is the hold up? what do you understand on why you are not opening? >> frankly, i have no understanding wife. once that outdoor museums would open up that we would get to reopen. we would have childcare for essential workers. we are outside. we serve the local community and the local families. i have no derstanding. b i reached out to francisco though department of public health and asked if the n francisco zoo would reopen. i had a one line response. the date is still pending. i followed up on why it was pending and i have not received a response. i have noreceived an information from the alameda county of help from the oakland zoo reopening. do you have the same lack information? are you getting redtape? >> noalameda county alth

department has been very supportive. the county supervisors have been supportive. the state said we are in stage iii. if they classified as as an outdoor museum we could reopen. they are still waiting pefor ission to let the zoos open. how are we different from an um outdoor mu that is what we have been dealing with. it is just a stay classification. ght now we are running out of reserves here >> reporter: what about for you? you have not been able to move forward . >> that is exactly right. we have the support of our board of supervisors. we have starbucks and other

retail units open but why not the zoo? >> reporter: i understand you are both concerned about the lack of the zoo opening and the financial situation of the zoo. neither of you want to be a vet there, you'rputting the safety measures into ace so when visitors come they will have a safe experience. could you tell us about the mekland zoo and of that measures you have put into place? >> i am glad you asked that. it is important in no way a visit to the oakland zoo will transmit the disease. we are basing it on science. the science said it is being transmitted person-to-person, primarily indoors in large oups. if you go to the safrancisco u will briefly pass anyone will along the pathway. you add em the requt of the masks and social distancing and we do hansen canisters and

disinfecting throughout the day, the risk of transmsion at the kland zoo, no matter how many cases are in alameda county the ri of transmissi is minimal. >> reporter: what about the sanc franzoo? have you taken similar measures? before the shelter in place our animal staff teams were ing masks . at that time we trre concd about from animals. we ha created a timed, online reservation system. you would have to have a reservation just like a staurant to avoid congestion. we have a one-way path. area so there is plenty of room for all of the families. >> reporter: if you cannot reopen what will happen to the

zoo? >> it is a city facility. it a city-owned facility managed by a nonprofit oforganization. our reserves would be transferred back to the city of oak and. then it would be their responsibity. >> reporter: what about san francisco? what are your thoughabout how that would happen and what the management of the zoo would to the city . d zoo needed to improve. ancisco the mayor said politics should day out of zoos. they spent millions of dollars and hundreds of hours to move forward. i fear we will gobackwards to the old zoos of the past that wa no one s to see again. >> reporter: what will happen to the animals if the zoos have to be turned over to

>> the city would have to find homes for them. primarily anotr zoo, wehave 750 animals. there is no way everyone would be able to find a home. the main reason is you have certain species like geriatric and more and you are trying to reintroduce her primate to a group. the social dynamics will not allow it. >> reporter: hoare th animals doing now without visitors? >> the animals are thriving thanks to the animal support team. i see that they are lonely. when walk around the primates come out immediately. they blow me kisses. the penguins foow me. the rhinoceros follow me. we provide them enrichment and

curiosity. >> reporter: thank you both so much . >> thank you. >> thank you. the coronavirus pandemic is a worldwide crisis. it is fostered increased collaboration among scientis across the glob researchers are looking into creating low-cost atvents, faced masks and other personal many of innovations are being rolled out around the worl. this is incles bolivia. they're working on a coronavirus kid that includes no electricity. they are learning new ways to work togemeer. joininby skype is the buyout engineer profession or . mr. co thank you for being on the show.

>> thank you for having me. we spoke with you a couple of months ago. you arinnovating ne technology. would you bring us up-to-date on your new mask? tell us about your ventilator prject . >> i think as we talked about last time, it has been approved in several countries in europe. i wanted meto ion some work that has gone and on facial coverings. this is our open source hardware design for a ventilator. this is a partnership between the univsities across the iversity. it is brown, stanford and the university of utah. we have tried to build a ventilator that will have the ts medical requiremto support a covid-19 patient. we want to do it in a contt of a global collaboration with

our manufacturing partners in kenya, indianepal and chile. we want to bring the brcapacity to g ventilators across the world in a manner that can scale as the needs are starting to rise. >> reporter: we have heard from some scientists. the pandemic has brought about an unprecedented scientific collaboration. can you tell us about the projects that are being worked on now? >> they have worked at communication. they w t to make sure itis assessable. how we support teams across the world and bringing the ideas and products to the market through the process and the specific countries. we are are on zoom calls tween 10 to 15 countries on a regular basis to essentially outpace he growth which the

virus has caught on in the global sector. >> reporter: i want to winter project that will allow covid project without electricity. this is been contacted in the amazon region. we hav this partner join us from bolivia. she is the coordinator for the next foundation. thank you for being on the show. >> thank you for the invitation. >> reporter: bolivia's president announced she has the virus. brazil's president announced he- had co19. can you describe the told the viruses haveanother region? particularly focus on the indigenous groups . >> at the moment mowe have than 44,000 positive cases of covid . 1600 people have died.

we share a border with brazil. the cases are increasing. we also shared the onamazon re for the indigenous groups we do not know how many cases we have. an unofficial report is that wee 50 indigenous people that are ck. we have atleast 30 that have died. we do not know the real said relation. they are in a turemot ion. they are along the rivers. we do not have the reports. it is complicated or >> reporter: this project will n hopefully covid testing to those regions. can you tell us more abt the device? >> yes, we have been working on this idea of converting and

building an electricity free covid test. could be conducted in the middle of nowhere such the amazon . what you are seeing is essentially a type of component that we built from parts a toy flashlight. we have been able to demonstrate that using sets of assets that were developed by a team at harvard and in the lata, they will it and converted into an electricity free test that can bepe ormed by saliva. this can take this to the remotest parof the world. this is where resources are nonexistent. we partnered with erica and her

team, we would like to ensure the test should be available no matter where you live. >> reporter: can you tell usth aboue tests will be dinosed? w will that research be conducted? how will it be deployed? lidate the test. nstance is to we will look at positive samples. we will e rk with of the local labs. weill monitor that the laboratory. we would do it in the field. we will do it in the amazon, there are leaves for indigenous groups that live nearby. depending on the local hospital. >> reporter: how is the veacceptance? >> i been working fomany years with the indigenous people. i have been working for 12

years on . different projec there is a good acceptance. many years. n each other for this is an advantage when you is work with type of group. it is also good, the local people, the indigenowh people is at risk. the experience of workg there ny years will help us. it will reduce the problems. the axis is restricted. yo reporter: can tell us about the learnings, working na internaty. we know you have done it on previous projects. what has this experience been like for you? you have been fiting the pandemic . >> the biggest thing that we think about is we are trying to see how technolo transfers arouthe world.

all of the covid projects at we haworked on are under an open license. that will allow manuducturers and rial partners to engage rapidly. i think to meet, the joy and the act of delivering the science is really neat to meet l peope eric, who is been there entire life in these communities. she understands the challenge. it has been valuable to engage early in the faces that you are seeing in this project. also, the sets of partnerships that we have created in kenya, nepal and indi we have rolled out the technology. times when we do research there is a serious nature to think about how the sets of products will deployed. we have had toput that front and center. if we cannot deliver these

innovations to people that need them, i am not so sure if we uld actually help them >> reporter: thank you so much for your time. >> thank you for having a or >> reporter: yocan find more of our coverage on our website on kqed.or cebook and instagram. itter, from all of us at kqed , thank you r watching .
