Health officials in Contra Costa County declared a state of emergency today because of the coronavirus. They announce new cases and say most people who have tested positive were infected by community spread. Andre senior here with more on that. And also the school that is set to undergo a deepcleaning because of one of their students is now in quarantine. Reporter on tuesday afternoon, Health Officials announced nine covid19 cases. And a tenth person with a presumptive case of the virus. Two of which were on the grand princess cruise ship during its trip to mexico in february. Two others came into contact with someone known to have the virus. The more troubling results though are from six people in the county who apparently caught the pathogen through an unknown source. Resulting in officials announcing new guidelines. People at higher risk of contracting the virus with heart disease, diabetes or chronic lung disease should avoid crowds of 50 people or more. We understand that these recommendations may substantially impact our lives and be difficult to implement. We considered them very carefully in consultation with the state and other counties who have taken similar actions. Reporter that development coming just as reports surface that a student in richmond tested positive for covid19 over the weekend and has been placed under quarantine. 30 of the school is not here today. The whole class was not here. Reporter a district spokesperson told me that the school will undergo a deep cleaning tuesday night. I think its the responsible thing to do. Reporter lawmakers have stepped up the board of supervisors, issuing an emergency proclamation that slowed the viruss spread and out of the growing concern that the six people who tested positive from an unknown sers got it from people already in the community. Meaning the virus is already spreading beyond what is currently known. Instead of having these unrelated cases, six of the towns here, it is indicative that its being transmitted person to person. And you dont know whos going to have it. Reporter at this point the Health Department has not made any recommendations about school closures. A spokesperson for the west Contra Costa Unified School district told me that the school in richmond will undergo that deep cleaning. The school will resume classes tomorrow. Happening now, another live look at the coronavirus stricken grand princess cruise ship. Hundreds of people are being screened as theyre allowed to get off the ship at the port of oakland. But its a very slow process. The passengers who are not sick are headed to military bases for 14day quarantine. We talked with a passenger who said people in her hallway were sick and had to leave the ship yesterday. There was a lady across the way. And she left yesterday. But i guess her husband is still in the cabin. But we really dont have any contact with anybody. Stella torres says she feels healthy and shes spent the past six days confined to her cabin. More live coverage from tom vacar. Youve been out at the port all day. How are things going today . Reporter well, they seem to be going along rather well. Not much excitement or anything like that. But they are going fairly slowly. And before this ship can get the deepest of deep cleanings in maritime history, they have to get those people off of this ship. They will be sent for a two week quarantine. So that at last, some day soon, they can call their home home. Every day the passenger population of the grand princess cruise ship begined ets. Dwindles, as more people leave the ship, and workers swab and test them before moving them onto a bus assignment. The process will now speed up. Anyone needing wheelchair, walker, or other assistance devices are now off the ship, leaving only ablebodied passengers who can move about on their own. Theresa Duncan Johnson of augusta, georgia, is excited and gratified that it will soon be her turn. Theres an end in sight at this point. And up until yesterday, we werent sure if we were gonna be really going to be here much longer. Reporter shell be transported by military aircraft to a base near her home for a twoweek quarantine stay. Its gonna be at dobins air force base is ch is in the atlanta area. Reporter according to the California Office of emergency services, as of last night, 173 americans were disembarked from the ship. Of those, 149 were transported to Travis Air Force in fairfield. 24 transported by ambulance. Presumably to hospitals. Another 232, all canadians, were transported to Oakland Airport to fly to a Canadian Military base. Two other canadians were transported by ambulance. At midafternoon today, the governor announced another 269 people were processed off the ship. But more are likely to come. Mary lou wilson of pleasanton is off the ship and will be at Travis Air Force for dinner. I have done well. I dont know how im gonna do on the next 14 days. But well take one day at a time. Reporter but she feels terrible for the crew that she leaves behind. I cant imagine what the workers are going through. And they are not gonna get to go off. Get off. They are gonna be quarantined here on the ship and out in the middle of the ocean. They have to leave the port. As soon as all of us are off. Reporter what we have is the situation where the boat continues to be unloaded. And it will continue to be unloaded as long as there were passengers that need to have either hospitalizations, which is not likely now, but certainly quarantined. Tom, they were estimating it would take three, four days to get all of the passengers off. Are we looking at the possibility that all of them will be off by tomorrow afternoon . Reporter i think that would be difficult. Technically you could say were probably up to close to 1,000 people. There are 2,400 passengers. So my guess is that they will get many of them off tomorrow. But i would be willing to bet you that itll take another day to finally get everybody off this ship. And then they have to deal with whatever medical things they have to do with the crew. And then this boat leaves for who knows where. Tom vacar at the port of oakland tonight, thank you.

Working closely with the cruise line industry. Very, very closely. Theyre taking very strong steps in terms of people going on and going off, but theyre spending a lot of money. And theyre working very hard. And were going to be helping that industry. Likewise with the airline industry, theyre taking very, very strong steps toward people coming into our country. President trump also said that discussed the administrations plan for a payroll tax break and other help for hourly workers with Senate Republicans today. The Vice President said that major Health Insurance companies have agreed to cover kroifb testing. All of our major Health Insurance companies have now joined with medicare and medicaid.

The white house says a million tests are currently available at state labs by the end of the week. 4 million more tests will be available on joining us is former fema coordinator, mark nouveau. Talking about providing some Economic Relief for our people and businesses impacted by the coronavirus. Your thoughts so far on the government response. We heard the epidemiologist from the health and human services. The federal agency thats kind of in chof the operation here. And he said unprecedented. Meaning its never happened in the united states. So how do we judge the operation . I think we can compare it to what happened a month ago on a similar cruise line with a number of passengers. And the outcome of that was 700 people being positive, and 23 dying. We dont see that happening now. What we see is someone, a unified, calm, operation. The passengers are doing a wonderful job. It appears as though its going very well. Wed like to talk to but the passengers. It is interesting to me, they have been stuck on that boat now for a while. Now theyre sitting in port. Theyre stuck in their rooms. Yet they seem very calm to me. I would have thought that maybe there would be some issues. Yeah. You know what . I saw something today where one of the gentlemen on the ship said it felt like a pariah. Meaning that here i am going on a cruise to hawaii and mexico, i think im gonna have a wonderful time. I cant even get back to a port because nobody wants us. So you add to this the trauma of being in your state room for a number of days. Somebodys gonna answer the door in a hazmat suit. You cant go anywhere for that period of time. Youre gonna face 14 days more on a military base in quarantine. Thats enough to kind of drive you a little bit of crazy. But theyre very cooperative. They seem to be supportive of the operation. And i think we would know that. Because they have communications outside. Theyre getting a tremendous amount of information from television and news. We know that. So i also read, one of the gentlemen there on the balconies, and hes telling jokes to people to enliven their spirits and get them through a difficult time. Unsung heroes are the passengers. I cant imagine what it would be like, and not to mention what its like for the crew members. And we dont know. A big uncertainty, or some uncertainty, as to where that cruise liner is gonna go. Can you imagine . 19 of the 21 initially tested positive were crew members. So you gotta figure theyre certainly most of the crew are probably from foreign lands. Thats typical for cruise ships. Not close to their families. Theyre gonna have to figure out how do i get through this after another 14 days of quarantine. Probably on a boat out in the oigz somewhere. I know theyre planning what to do with those folk. But boy, the mental stress that comes with all of this is incredible. Unprecedented. Thankses, mark. Youre welcome. We have complete coverage for you on our home page, ktvu. Com.

We still have to heal but were trying to make it down. Hes not crazy. He said it himself. He knew what he did. So youre not crazy. So they should see that tomorrow.

The case was still ongoing with the same jury tomorrow. Now to politics and another big night in the democratic race for the president ial nomination. Six States Holding primaries. Polls have closed in four states and results are starting to trickle in. Were ginned by greg lee with a look at the numbers. A crucial night for joe biden and Bernie Sanders as they go headtohead. More than a third those delegates in michigan. The ap and fox news have called missouri and mississippi for joe biden. And now the latest poll calling michigan for joe biden. 62 reporting. 41 for sanders. Some context to this. This is where sanders shocked a lot of people in 2016. Hillary clinton had led in the polls only to sanders win it. It reinvigorated his campaign after a number of super tuesday losses. He needed to do the same thing here. They both have spend a lot of time and money here. This will certainly be a disappointment for the sanders campaign. In mississippi, heres how the numbers look after it was called for biden. 82 for him resounding. 14 reporting. We expected to biden to do well here, bolstered by the momentum and continued support of the African American vote. Exit poefls showing eight in ten black voters tonight voted for biden in the state of mississippi. Missouri now going to joe biden. Biden winning there this is a place where sanders lost by just 1,500 votes in 2016 he want expected to maybe do well or draw close. Not terribly surprising its going to joe biden. Heres a look at the delegate map so far. Biden getting a huge boost after winning ten states on super tuesday. Sanders, a big win in california but exactly how many delegates he gets still being determined. Still some big prizes in florida, illinois and ohio taking place next week. It is important to note that its good to win. But the margin of victory is important as we look to break down some of these delegates. Getting the black vote, big for biden. With Bernie Sanders, is it eventually coming out thatted by sen gonna take the nomination . Do you think sanders will fall in line and urge his supporters to back biden . I think its gonna be interesting. Because the ideologies are so different. Youve got this progressive wing and then youve got the moderates, kind of the establishment with joe biden. But weve seen kamala harris, cory booker, klobuchar, buttigieg all get behind biden. Sanders base is so on fire for him and they do such a good job of inspiring voters at the grassroots level, its really unknown what theyll do. I think that is a long and hard decision he will have to make. And still wants to debate on sunday against biden. All right. I know youll be following it for us. Thank you.

San jose and the airport, over the past few showers. We still have a chance of an isolated shower for this evening. Mainly south of San Francisco. For the most part, we just have the clouds drifting in. From the south. Current numbers still mild out there, talking about some 60s and still some 70s. There is our live camera toward the golden gate bridge. Just a few high clouds ifting in. Overnight lows will be in the 40s to around 50 degrees. And we continue to track those clouds for tonight.
