Covid19. This is at the msc south shelter right off of fifth street. Abc7 News Reporter stephanie sierra following with the latest, and she joins us live from the newsroom. Stephanie . Yes, larry, this is one of the largest known covid outbreaks in the bay area at a homeless shelter of the 70 people tested positive, 68 are living at the shelter. The other two are Staff Members. Here is what we know about the shelter. Its part of the st. Vincent de paul society of San Francisco. Mayor breed made it clear this shelter was a known hot spot on any given night. The shelter accommodates more than 340 people. But as of last night, there were only 100 people in the shelter as many others are now being housed in hotel rooms. Because of that, breed says the shelter was able to quickly transition into a medical facility, even touting the city was both prepared and quick to respond to this outbreak. But San Francisco supervisor matt heaney, an outspoken advocate for the homeless says just the opposite, calling the citys actions an utter failure. Im furious. The reality is that people cannot be in these large crowded environments because the virus spreads. So why have they been there for a month . Why havent they had separation where they sleep . Why havent they had mass abouts . But the fact is we were on top of it. We know that there are a number of people who have tested positive, and we are going reroute our medical health experts. Medical support and supplies will be provided to the shelter to help manage the outbreak. And i just got off the phone with staff at msc south who could not confirm to me if the 70 people who tested positive will be moved out of the shelter to hotel rooms. Thats just unclear at this point. But well keep you posted as we learn more. Live in the newsroom, stephanie sierra, abc7 news. Thank you, stephanie. In the greater bay area, there are now more than 4600 confirmed coronavirus cases. 126 people have died. Alameda and contra costa counties saw an increase in both cases and deaths this afternoon. Santa clara county still has the most confirmed cases in the region with more than 1400. Farther north, lake county has three confirmed cases. And Mendocino County cases have held steady at four. Three of those patients have recovered. Positive news today, though, from the Governors Task force. The states stayathome order on social distancing measure is working. The States Health secretary showed us where hospitalizations stand right now. Circumstances we were worried that we were going to see something that got close to 700,000 hospitalizations across the state. We see that we are holding on the bottom part of the model. Thats sort of the better case scenario, what we had always hoped for this. Is a point of pride for californians that weve done so well. He and the governor warned people should keep social distancing and stay at home or those numbers could radically change. Governor newsom also announced a partnership with fema to provide mals to seniors, and said the state is monitoring 191 Nursing Homes with active coronavirus cases. California is making a huge dent in processing coronavirus tests, but were still coming in close to last compared to the rest of the country. California is ranked 45th compared with the other 49 states and washington, d. C. As of thursday, california had results for 177,600 tests, or 449 per 100,000 people. The state has drastically improved in the last few week, but has a heavy backlog to process. For those without a fever, its extremely difficult to get a test. Health Officials Say this has made it difficult to understand the infection pattern. Now, in the last 24 hours, one of the most searched items on our website, abc7news. Com, is about a phenomenon called herd immunity. And well explain what that is. Its when enough of the population has become infected that it would be safe to lift social distancing and shelter in place orders. A senior fellow at stanfords hoover institute, Victor Hansen theorizes covid19 could have really been the cause of californias early flu season. Now he is not a doctor and not part of a study that stanford researchers are conducting. He is a military historian. He wrote an article that with many traveling from wuhan, china to california during the fall and winter month, its likely many people were exposed to the virus in this state, and that might explain why the rate here is lower than it is in new york. Now we contacted Stanford University today. They say the medical researchers are still in the middle of their study and theyre not ready to release any results yet. Joining me now is abc7 news medical expert dr. Alok patel. Thanks again, doc, for joining us. Lets get into this herd immunity and now viable it is and what percentage of the population would have had to have been exposed in order for herd immunity to help us out here. So larry, you nailed it when you were explaining what herd immunity. Its basically a percentage of the entire community who would need to be immune to an infection so the infection couldnt spread from person to person. And so when we look at coronavirus, we talk about that number, around two to three. That reproductive number, of how many people can be infected from one case. Now with coronavirus, were suspecting that we would need about 50 to 60 of the population to be immune to it to achieve that herd immunity so it couldnt spread like wildfire. Now ill give you an example. With measles, the reproductive number is way higher than two to three. Its greater than 15. So for measles, you need 90 of the population to be immune. Think of that. 50 to 60 immune to this coronavirus . That would mean that we would need millions and millions of americans to actually get either infected or vaccinated to get immune to create herd immunity. Thats a huge number. Yeah. And we probably have a huge number of casualties and deaths if you had infections in the millions. Do you think its possible that californias rate is lower because people unknowingly got there was the story before i mentioned that somebody at stanford who is a military historian suggested that it was here early. We just didnt know what it was. I think the latter is possible. A lot of people have mentioned we may have had covid19 here a few months earlier than we suspected and it could have been spreading. But again, i would have to go back to the numbers and really look at the fact that weve had so many cases pop up all over the country and people are dying. Theyre getting hospitalized. Theyre getting extremely sick. And before we were actually testing for covid19, those that came up as mysterious cases. So i would believe that local Public Health experts and physicians still would have been saying hey, were having a lot of people hospitalized for something, and none of our tests are coming back positive. So that never came up. Now its possible in the past somebody may have died and they would have said this is pneumonia or respiratory failure, and they werent exactly calling it covid19. But, again, if we say that, 50 to 60 need to be infected to have herd immunity, thats hard to believe. Right now the united states, we have about 19,000 deaths at a 500,000 cases, thats a little bit more than 3 . So to achieve herd immunity, were going to be talking about 150 million americans infected or better yet, getting them vaccinated which would do this in a safe way. Get the herd immunity. Lets talk about Antibody Testing, because in theory, if you knew you had been exposed to covid19 and then recovered, theoretically, you should be able to go back to work. I know there have been some cases where there is speculation about reinfection taking place, but most viruses youre the doctor here. You should be explaining this. Most virus, once you get it, you can get it the second time . Youre doing a great job. But youre right. We theorize with this virus, as with many others, if you get infected, youll build up antibodies over time, and those antibodies will protect you from a reinfection. Now because this is a novel virus, scientists dont yet know wat is defined as immunity or even how long it lasts or how long it builds up. Those are the things we really need to learn, hopefully from this Antibody Test. It was just fdaapproved on april 1. We need to see a lot more testing with this Antibody Test because that will really tell us how many people may have been exposed in the past, and how widespread this disease is among people who may have had really serious symptoms or may not have been hospitalized. Doc, thanks again for the time. Have a great weekend. Have a safe weekend. And well see you on monday. Okay . Thank you, larry. Be safe. All right. Lets go to ama. Yeah, thank you, larry. A university of San FranciscoResearch Scientist says Governor Newsom should put a mandatory mask law in place. He put together a team of experts to study the data and says Available Evidence says near universal adoption of nonmedical masks when in public could successfully reduce and stop community spread. He appeared on our new 3 00 show to talk about this research. We now know that masks are best used when somebody who might be infected wears it. So if you go out to the shops and somebody there is not wearing a mask, they could kill you. Dire. Some california cities and counties have started requiring people wear masks when in public. Pedestrians will no longer have to press buttons if they want to cross the street in emeryville. The city made the move last night to automatically activate the socalled beg buttons in response to the coronavirus outbreak and to limit potential exposure risks. This is a temporary change and does not apply to intersections that are run by caltrans. Its easter weekend, but for some its going to be difficult because of social distancing. And some bay area parks are being proactive, shutting down to keep people safe this weekend. Plus, youve been sitting at home for weeks. It probably means your car is just sitting there as well. Later this hour, what you should do to make sure your car actually starts back up when you really do need it. Im spencer christian. The weather weve been waiting for is finally here, just in time for easter we are the thrivers. Women with Metastatic Breast Cancer standing in the struggle. Hustling through the hurt. Asking for science not sorrys. Our time for more time has come. Living longer is possible and proven in women taking kisqali plus fulvestrant or a nonsteroidal aromatase inhibitor. Kisqali is the only treatment in its class with proven overall survival results in 2 clinical trials. Helping women live longer with hr , her2 Metastatic Breast Cancer. Kisqali was also significantly more effective at delaying disease progression versus a nonsteroidal aromatase inhibitor or fulvestrant alone. Kisqali can cause lung problems or an abnormal heartbeat, which can lead to death. It can cause serious liver problems and low white blood cell counts that may result in severe infections. Tell your doctor right away if you have new or worsening symptoms, including breathing problems, cough, chest pain, a change in your heartbeat, dizziness. Yellowing of the skin or eyes, dark urine, tiredness, loss of appetite, abdomen pain, bleeding, bruising, fever, chills, or other symptoms of an infection, are or plan to become pregnant, or breastfeeding. Avoid grapefruit during treatment. Kisqali is not approved for use with tamoxifen. Its our time. To continue to shine well, just in case youve lost track, it is friday, april 10th. Its good friday as we head into Easter Sunday, day 25 of our shelter in place in the bay area. And starting tomorrow, oakland is closing off streets so people can safely get outside during the shelterinplace order. Its being called oaklands slow streets. Sky 7 flew over a few of the streets that are going to be closed off. You see that here. Only pedestrian, bicyclists and those in wheelchairs will be able to use them. People who live on the streets will still be able to use their cars. So will delivery drivers and First Responders who need to access those streets. But theyre going to need to take it slow. Mayor libby schaaf says its about allowing people to get in some exercise while being responsible at the same time. Oakland slow streets is trying to send a message that we want oaklanders to recreate in a socially distanced manner, a physically distanced manner. The city is starting with four streets as part of a pilot program, including 42nd street between adeline and broadway. The plan calls for a total of 74 miles to be a part of the program. If you are thinking about going to park for easter weekend you might want to rethink those plans. San mateo county and east Bay Regional Parks are among the places that have announced closures or restrictions on parking to prevent overcrowding. San jose is closing all of its regional parks for the weekend as well. Santa clara countys parks, those are going to remain open. Thousands of warning citations have been handed out in marin county to drivers because people continue to visit parks and other recreation areas. The Sheriffs Office is reminding people that driving to parks or an open space is considered nonessential travel during the shelterinplace order. No Parking Zones have been marked around these areas. The Sheriffs Office says if you need the get out, please, please do it near your home. Lets turn now to some consumer news. Yes. Lets get to it. A warning about scams from 7 on your sides michael finney. Michael, it just seems like these are coming out of the woodwork here with everybody touting cures and bogus remedies for covid19. Its awful. You guys can tell, youve been reading your own email. Everyone is getting these things. Whats happening is the bad guys are taking every old scam they can think of and then theyre putting a coronavirus twist on it. Let me show you several that ive been tracking. The federal trade Commission Says phony websites are cropping up, offering help and cleaning products, like this one selling face masks and even toilet paper. Many offer hard to find items like cleaning wipes and hand sanitizer. The consumers place orders that never arrive. Heres what one viewer received when she ordered toilet paper online. She paid 28 for this. Youre paying for it because, you know, the advertisement is so convincing, and you dont get anything and youve lost your money. Before you buy from an unfamiliar website, check out the sell erion line. Type in the name and look for reviews or scam reports. Authorities also are warning about malicious smartphone apps. One of them offered to track covid19 cases near you, but those who downloaded the app found it lobbed their phone. Then this threatening message appeared saying your phone is encrypted. You have 48 hours to pay 100 in bitcoin or everything will be erased. Your social media account will be publicly leaked. Gps is watched and your location is known. Finally, look out for emails pretending to be from the government. This one claim to be from the world health organization. With information about coronavirus. Instead, clicking on the button installed Malicious Software on the victims computer. Now tonight at 6 00 on abc7 news, im going to bore down into a new hacking scheme. This one takes digital skimming. You know about skimming . Weve talked about that at atm machines, gas stations and the like. Well, now they figured out how to do it online. You guy, ill show it all to you tonight at 6 00. As if we dont have enough. You always find a way. To worry about. Thank you. Facebook has a new feature that makes it easier to manage your time in quarantine. Quiet mode. Mutes notifications from the app for a set period of time. If you try to open the app while youre in quiet mode, it will remind you were trying to be quiet in quiet mode and get away. Can i put it on quiet mode for a year . Facebook also added shortcuts to notification settings and feed preferences. I suppose that could be helpful, right . Weve got a beautiful weekend ahead. Spencer christian is here. I dont mean to pry, spencer, but it looks like were getting a nice tour of your house. Casa christian. He started in one room with the ali painting and another room yesterday. Are you in the kitchen now . Where are you . This is part of the family room. My computer wasnt working well over in the office where i used to be because we had weak wifi connectivity over there. My wifes computer, which is right next to the modem, and im Getting Better connectivity. So thats why i moved. Lets move along. Take a look at whats going on. Here is a live view outside at mostly sunny skies. Current temperature readings are 61 in San Francisco. Mid60s at oakland, redwood city and gilroy. A cool 57 at half moon bay. Nice view from the rooftop camera. Its 69 in santa rosa right now. Petaluma 67. 67 also in napa. 71 at fairfield and mid to upper 60s at concord and livermore. And these are our forecast features. Well see low fog and low fog and clouds expanding overnight. Mainly sunny and warmer for easter weekend. And the warming will continue well into next week. Now look at this pesky upper level low of the satellite image. You can see the movement into the southernmost part of california. This system has been a factor in our weather all week long. Earlier in the week it brought us substantial rainfall. And then even as it moves southward, the cold air associated with it brought out temperatures down below normal. A few isolated showers continuing to move through the bay area, even into earlier today. Right now were looking at the forecast animation taking us into the nighttime hours. Well see the reach of the low clouds and fog pushing across the bay inland. Tomorrow morning it will start to burn back to the coastline giving us a mainly sunny day, certainly by midday. And as we go into sunday morning, you see thats going to start off as a sunny day also for easter. And it will remain pretty nice positive weekend for us. Certainly going to warm up a bit. Overnight lows under a foggy and partly cloudy conditions will remain in the upper 40s to
