presumptive case of the coronavirus awaiting conversation from the cdc. washington state meanwhile has announced two presumptive cases one likely travel related and one possibly spread through the community. new cases confirmed in california including that state's second case of unknown origin. and there are now at least 62 confirmed cases total in the u.s. globally there are more than 85,000 cases in at least 60 countries with more than 2,900 deaths. >> the world health organization raising the global risk assessment to its highest level as denmark, estonia, lithuania, the netherlands, nigeria and mexico all confirm their first cases of the virus. >> the cdc announcing it will now allow states to do their own testing, but the agency will still need to confirm positive results. abc's kaylee hartung is at u.c.

davis medical center in sacramento where a woman contracted the virus apparently without having contact with anyone who traveled abroad. she is in serious condition. kaylee, good morning to you. >> reporter: good morning, eva. the number of cases in the united states is growing. the latest concern highlighted by that woman hospitalized here in sacramento. people getting sick by unknown lines of transmission. overnight new coronavirus cases on the west coast. raising concerns of a potential pandemic. in california, health officials confirming another case of unknown origin. >> like the california case reported two days ago, our third case did not recently travel overseas or have any known contact with a recent traveler or an infected person. >> reporter: the new patient health officials say is a woman who's had trouble breathing. now hospitalized authorities are racing to track down anyone she may have come into contact with. and in oregon overnight that state's first presumptive case of covid-19. >> there was no known travel exposure for this individual so this is a case of community spread of the disease much like

the case in california. >> reporter: the patient, a school employee who may have exposed students and staff, but public health officials are also urging caution, and in washington state, a student who developed symptoms early last week but apparently returned to school after feeling better. >> there was no travel history associated with this case. we do not yet know the possible source of infection. >> reporter: the cdc is now permitting states to do their own virus testing. the goal, to have every state and local health department up and running by next week with this kit. while post cases appear to be mild, states are doing what they can to contain the virus. as more hospitals gain access to kits, the number of diagnosed cases will most likely rise. the world health organization has raised its risk level for coronavirus to very high at a global level. they also say many hospitals around the world are not prepared for the epidemic, whit. >> certainly alarming. kaylee hartung, our thanks to

you. and the spread of the coronavirus around the world is raising concerns about travel as well, and the state department newark liberty international airport with the latest on that side of the story. stephanie, good morning. >> reporter: whit, good morning here at newark airport roughly 1,200 planes fly in and out every day. that's thousands of people from around the globe interacting with each other, and there are questions about which travelers from which countries should be screened, but we're now learning about a government worker who returned to newark from china bypassing the quarantine period. this morning, new concerns about the handling of the coronavirus outbreak. a union representing government workers says an employee for the department of homeland security was told to report to work in newark after returning from travel in china. a violation of the quarantine

period. the employee ines ising and prevention procedures. around the globe 58 countries have been impacted, countries in asia taking a huge hit. in south korea an american service member and his wife have both fallen ill. the state department now raising its travel advisory for italy to level 3 telling americans to reconsider travel. >> first it didn't seem too bad but then milan which was up north of us started getting a lot worse a lot quicker. >> reporter: overnight, students from the university of new haven deciding to cut short their study abroad in italy. >> there was any chance i couldn't travel because of quarantine or something else i was just like i'd rather be at home. >> reporter: dhs says they've been screening all passengers coming from china. the virus' epicenter. by routing passengers through 11 airports here in the u.s. dhs has not returned abc's

request for comment about whether passengers from other hard hit areas are also being tested. dan. >> stephanie, thank you. as with nearly everything else in this profoundly polarized era, coronavirus has unsurprisingly become a political issue. president trump out there defending his administration's response to the outbreak as his critics attack. abc's kyra phillips is at the white house this morning with more. kyra, good morning to you. >> reporter: good morning, dan. well, from a diving doubt of protective gear to protecting the message as the coronavirus continues to spread, the white house challenged daily to come up with answers. overnight, president trump counter-programming the democratic primary in charleston, south carolina, insisting he has everything coronavirus under control pushing back on democratic criticism. >> the democrats are politicizing the coronavirus, you know that, right.

coronavirus. >> reporter: this coming prior to the emergence of more baffling cases where patients tested positive, but had no obvious contact with anyone with the virus. and the message from the white house in recent days pointing the finger at the media. >> the press was covering their hoax of the day because they thought it would bring down the president. the reason you're seeing so much attention to it today is that they think this is going to be what brings down the president. >> reporter: on capitol hill anxiety over the virus is bipartisan. republican senator thom tillis writing a letter to the defense secretary saying, this global outbreak is concerning and presents an enduring and uncertain threat. the outbreak also rattling markets with wall street having its worst week since the 2008 financial crisis. sparking fear of economic downturn. the president blaming the recent stock market troubles in part on the democrats running for president. >> i also think the people are

not happy when they look at what's running on the other side. >> reporter: eva, as you know, the administration has been facing a lot of criticism for its messaging, but the white house is claiming transparency, actually dispatching dr. anthony fauci, one of the country's leading experts on the contagious diseases to brief members of congress and when i spoke to dr. fauci this week i asked him about reports that the white house directed him not to say anything further about the virus without clearance. well, he told me that was not true and that those reports have been taken out of context. eva. >> all right, thank you so much for your reporting. let's bring in abc news chief medical correspondent dr. jennifer ashton joining us from massachusetts this morning. first of all, let's get right to it. who should be tested and why? >> eva, that has been the issue this week and for good reason. here are the new guidelines issued at the end of the week from the cdc to help guide evaluation for persons under interest or investigation for

having coronavirus. let me take you through them. it requires evaluation with testing for someone with a fever or signs or symptoms and close contact with a known case of coronavirus or fever and symptoms requiring hospitalization. that really is a response to that first community acquired case we saw in california where there was a delayed period of testing in a person who has recent travel to one of the highly affected areas. lastly, someone with fever and severe lower respiratory disease so this is someone on a ventilator in an icu setting where we can't find any other explanation. eva, if you walked in with a fever and cough you would be checked appropriately for influenza but for coronavirus and we have a saying in medicine, when you look for something, you will find it so we do expect to see more cases, even community acquired ones. >> now, what about the timing and capacity? what is going on at the state level? >> that's getting ramped up

quickly. we heard the cdc say by the end of this week, they want states and local health democrats to be able to run their own tests. that will help to expedite things. if they were to get a positive result that specimen will need to be confirmed in atlanta, but, again, we're seeing a lot of catch up. theyprocess these tests at the state and local level. >> dr. jennifer ashton for us, thank you very much you so much. more on the coronavirus coming up including dr. ashton answering your questions about the virus. whit. all right, eva. the other big story we're following this morning. the voters are heading to the polls in south carolina. a primary that could determine if anyone has enough voter support to slow bernie sanders in the race to the democratic nomination. abc's rachel scott is in columbia with the very latest. rachel, good morning. >> reporter: whit, good morning. former vice president joe biden has a lot on the line today. he is looking to prove his strength in this race, counting

on south carolina for a comeback and hoping a victory here will launch his campaign into super tuesday. this morning, the polls are in south carolina, and joe biden is banking on the palmetto state for a rebound. >> if you send me out of here with a victory that's significant, i think i'm going to be the next nominee of the united states presidency. >> reporter: the former vp dropping by a columbia barber shop, winning over some with his pitch. >> i'm going to vote for joe biden. plain and simple. nothing or no one can change my mind on that, okay. if i lose, i'm going to lose with joe biden. >> reporter: biden is confident he will win today's primary. black voters here made up 60% of the electorate in 2016. do you think a win in south carolina will give your campaign enough of a boost going into tuesday? >> i think i have enough of a boost already. >> reporter: but others are flooding those states outspending biden on ads. >> if you think my campaign is expensive, just imagine what c.

massachusetts rallying thousands on senator elizabeth warren's home turf. >> so this tuesday, super tuesday, very important day, may be the most important day in the whole primary process. >> reporter: warren fighting to gain momentum telling me her closing argument. >> i've been fighting all my life for my family and for working families. >> reporter: and this race is turning national. the next three days will be critical. almost every single candidate will be visiting a super tuesday state today and billionaire mayor michael bloomberg is beginning a massive push. his campaign plans to hold more than 2,000 events in 30 states ahead of super tuesday. dan. >> he's got the money to do it, rachel, thank you. for much more let's bring in abc senior national correspondent terry moran who is right there in charleston, south carolina. terry, good morning to you.

just given the war chest from michael bloomberg and the ongoing strength from bernie how big a victory does joe biden need in the state where you stand right now to rack up enough of a head of steam heading into super tuesday? >> reporter: well, he sure needs a win. there's no question, and a win is a win. for awhile, his polls were shaky, and he was ggrehe blk mmit but heoeneed to pop here. it seems his support is more dutiful than enthusiastic. you think of those armies of young bernie supporters. he doesn't have that and he needs money. joe biden's campaign is almost thread bare. he's not advertising in super tuesday states. look, this election is about to ramp up from state by state to a national debate, a national election with super tuesday coming up. he needs money to get in those expensive media markets. he needs to demonstrate here

especially since his argument is he's the electable one that he can win. >> here's another x-factor which you pointed out to me when we were emailing before the show. in what ways could the coronavirus shake up this race going forward? >> reporter: you know, there's no question, coronavirus is naturally and quite properly going to be an issue for a lot of voters going forward, and it does scramble the race. it has that potential. all of a sudden these candidates are going to be measured a little differently. many voters might judge them them on how they might handle the threat or the actual fact of a looming pandemic. candidates with more experience, maybe biden or bloomberg handling big issues might do better with some voters. voters might second guess a very young candidate like pete buttigieg. this is speculative, but there is no question that president trump as well will be judged on this issue and others, that's not just politicizing it. that's a fact. this is a major public health issue, and a presidential election. the two will collide and at the end of the day, how can you hold primaries, conventions, even a

general election when there is a contagion in the country could be a practical and pressing question as we go forward this year. >> indeed. well said. we are heading into a turbulent time. terry, thank you very much. we really appreciate it. and a reminder, abc news will have complete coverage tonight on abc news and on our streaming channel abc newslive and don't forget on super tuesday, special coverage of the 15 contests across the country. that starts at 8:00 eastern. well, america's longest war may finally be nearing an end. the u.s. signing a historic deal with the taliban that could allow for the withdrawal of u.s. troops from afghanistan. abc's julia macfarlane is in london with those details. good morning, julia. >> reporter: good morning, eva. that's right. that signing ceremony is taking place just in a matter of minutes and secretary of state mike pompeo is there in doha to oversee the formalities. the agreement establishes a timetable for the withdrawal of u.s. troops in exchange for guarantees from the taliban not to allow groups including al

qaeda to operate in their territory. initially the u.s. troops will be reduced to just over 8,000 down from their current level of 13,000 stationed in the country. we expect that to happen in the coming weeks. now, this agreement does not mark the end of the conflict but it is hoped it can finally pave the way for a lasting peace. remember, the u.s. has spent three-quarters of a trillion dollars on this war and tens of thousands of lives have been lost including some 2,300 american soldiers in its 18-year history. whit? >> all right, julia macfarlane for us. a pivotal day. thank you so much. we want to turn to weather. rob is here talking about a lot of snow in the northeast this morning. >> happy leap day, by the way, february 29th. last day of february. we're going out in a cold rather wintry note. march 1st the meteorological first day of spring. there is hope. look at this. we had blizzard conditions across parts of western new york

and pennsylvania. eastern pennsylvania, western pennsylvania, excuse me, jefferson county. you are slogging through blizzard conditions. some areas had three, even four feet of snow. a little farther south and west towards erie, this snow coming off lake erie and this area along the interstate getting enough snow obviously to cause some problems. these lake-effect snow bands still cranking off especially lake erie right now. michigan and superior also seeing some big snows but these will wind down and upper level support down across the south as the cold air sunk all the way down well into the south. windchills minus 8 in green bay, 7 in detroit and not so warm here in the northeast. good saturday morning. i'm lisa argen waking up to sunshine here in the city. but we will be cooler this weekend, especially today, about 15 degrees cooler. wind advisory por for most

tomorrow but then we warm up to next week. how windy in 30 to 40 miles an hour winds at the coast. 15 to 20 around the by. breezy out there and cool. the accuweather seven-day forecast just 60s over the weekend. warmer next week. this is a leap day but one more week before we spring ahead on the clocks. >> i thought the groundhog saw his shadow. wasn't that supposed to be early spring? >> yeah. yeah. >> he's not right, is he? >> it's coming. >> rob has problems with the rodent. >> punxsutawney. >> always bring up the rodent. it's really unbelievable. we had spring. it was early. it was in january. >> doesn't count. moving on a small plane traveling from idaho made an emergency landing in california after some scary moments in the air. the plane carrying four passengers and the pilot coming from idaho falls touching down in san jose, california, after a 45-minute ride. the pilot reporting mechanical

difficulties. everyone involved was able to make it off that plane unharmed. all right, janai is here with an amazing leap year birthday story. what's going on? >> this is really good. second grader chloe davidson usually has to blow out birthday parents on what her parents call her unbirthday, but not this year. today leap year babies everywhere are getting that once in every four-year chance to celebrate their actual birthdays and for the davidsons today is twice as special. both chloe and her sister joelle were born on february 29th. chloe in 2012, and joelle in 2016. >> how would are you going to be this weekend? >> 2. >> 2 years old. you don't look 2 years old. >> just add another twist to the story, the doctor who delivered the girls in new jersey also happens to be a leap year baby. >> that's crazy. >> happy birthday to joelle, chloe and dr. grossman and all the other leap year babies out there. >> what are the odds of that? >> their parents said they tried to plan it that way. >> to have them both born --

>> they said they tried to and did it. >> that is some accurate planning. >> how are they able to -- >> i mean -- >> let's not get into the details. >> eva is always going to ask the important question. how exactly -- >> i mean, i know how it happens. >> right here. >> we'll tell you about the birds and the bees during the commercial break. in the meantime though, still ahead on "gma," school districts across the country on high alert for a potential outbreak of coronavirus. what they're doing to prepare with one school temporarily shutting down because of possible exposure.well, bullets stopping a man who hijacked this ambulance, ramming into police cars. how they finally got him.

oregon has confirmed its first presumptive case of the new coronavirus which is awaiting confirmation from the cdc as washington state announces two travel related and one possibly spread through the community. new cases of covid-19 also confirmed in california. there are now at least 62 confirmed cases in the u.s. and globally there are more than 85,000 cases in at least 60 the other big story happening right now, this could be a hugely consequential day in politics. the voting begins in south carolina where the polls are officially open. democrats battling for delegates as joe biden is banking on the palmetto state for a rebound after trailing bernie sanders. the candidates making one final push while flooding delegate rich super tuesday states with expensive ads. that's just three days away, super tuesday. >> absolutely. take a look at this. as a would-be robber gets doused by a motion activated sprinkler installed on someone's pickup truck. yes, the truck owner taking action after thieves have been

in washington state, bothell high school closed on thursday to disinfect the building out of an abundance of caution after a staff member's relative was hospitalized for possible covid-19 symptoms. >> i don't believe that closing 1 of our 33 schools for a day to do deep cleaning after receiving the information we have incites any type of panic. >> reporter: other schools are limiting travel outside the united states hoping to reduce the risk of bringing the virus back home. >> schools can, in fact, be a hotbed for dissemination of the virus. >> reporter: in communities like miami-dade county where up to 150 international students enroll every week, administrators are turning to technology to maintain normalcy for students in the event that schools must close. >> we have hundreds of thousands of personal devices, many of them that we can put in the hands of students. what that means, should children be kept at home for whatever reason, continue a schooling process for them? >> reporter: the possibility of

long-term school closure in the u.s. is raising another set of concerns for parents including the cost of child care and access to the technology needed to be able to take in that remote learning. >> to do the continuous learning. my wife and i are talking about what are we going to do stuck in the house all day with kids. an issue with you as well. >> a lot of unknowns. zachary kiesch, thank you so much. we want to bring in dr. jen ashton back with us, our chief health correspondent joining us from massachusetts to answer some questions from our viewers about the novel coronavirus. dr. ashton, good morning to you once again. let's jump right to it here. the first question we have for you, this from a viewer, if officials do close schools and/or work, how long could they stay closed? >> that, whit, is tbd as we say, to be determined. we don't know. right now we're just getting these plans into place, so i think we're going to be seeing some variety there on a case-by-case basis but we just don't know yet. >> all right, another viewer is

asking with spring break coming up, is traveling safe and this person has family vacationing to mexico. >> right. that is such a big question. no one has a crystal ball here. i think in general it depends on when you're going away, where you're going. you can see what's going on in terms of coronavirus to some degree in that area but it also depends on people's risk tolerance. you know it's not just the risk of getting sick but the risk of your travel and potentially your re-entry to this country if you're traveling internationally being disrupted so, again, that's for each person to decide. >> yeah, where you're going being a key part of that question. all right, a third question here from a viewer, do you think coronavirus will be over by summer? >> same answer about the crystal ball, whit. no one knows because we don't have history or track record on this coronavirus how it will behave in the warmer months. but it's important to remember because this is now affecting the world.

when it becomes summer here it's winter in the southern hemisphere so we know from mers that it spread in hot temperatures around the arabian peninsula. we just don't know what this will do. >> quickly, i want to go back to your crystal ball here for a moment. finally this viewer asking, when will they have the vaccine ready? >> short answer 12 to 18 months. they're going to start phase one clinical trials in april. isndanotr countries also working on it but, whit, such good questions from our viewers and followers this week and we really appreciate them. they're really helpful. >> absolutely. people have to stay on top of that information. dr. ashton as always, thank you so much, and we know you'll be right back in our second hour with five things you need to know about coronavirus. >> great questions, unfortunately, just not great answers at this point and that's why the story is so confounding. let's check the weather and robert is standing by with more on that. good morning. what's going on? >> good morning. are you ready for the next storm? here it is on the west coast, northwest, seattle to portland,

snow levels about average for this time of year, rain in the valley, snow at the top and this will be pushing south and east so san francisco, los angeles tomorrow, gusty wind, cool showers. snow levels there 3,000 feet so the grapevine may be impacted and heavier snow in the inland areas of the mountains. monday and tuesday, here's where we run into problems, nashville and birmingham, areas that need no more rain, and another piece of energy comes into the upper levels. not only rain but potential for severe weather tuesday, wednesday from southeast texas across parts of dixie in thrgh through it. another two to three inch, maybe three to five in some areas where they don't need it, they good saturday morning. we're seeing temperatures cool way back today. we have a front on the way increasing the clouds throughout the day today. upper 50s coast to to it low 60s inland.
