coronavirus, and there is good reason to believe more people will test positive in the coming days. now the question is how did this virus take root here in kirkland, washington, and how many of the so-called walking well, people with the virus but not showing symptoms exist here in the state. the state's public health officials have ordered tests on a quarter of lifecare's 108 patients and 25 staffers, all exhibiting coronavirus-like symptoms. two elderly patients already tested positive. officials say a number of the senior center's residents were recently treated at nearby evergreen hospital, where the 50-year-old man died. how that man got so sick is now the subject of a federal/state investigation. >> we do not know how he contracted the virus yet. that's why we and the state of washington are deployed out there to try to trace who he had contact with and how he might have gotten the virus. we don't have a discernible connection to any travel to korea or china or any other

♪ >> announcer: this is the "cbs overnight news." >> i'm errol barnett, and we've got a lot more to tell you about this morning, beginning with the coronavirus. the potentially deadly virus continues to spread around the world, most notably south korea,

iran and italy. here in the u.s. there has been one death reported and a lot of fear. our dr. jon lapook puts things in perspective. >> reporter: coronavirus began in china several months ago, and since then the virus and fear of it have been spreading around the world. there is no vaccine for coronavirus yet, but there is a treatment for fear. it's called facts. and here is a dose of them. coronavirus causes a rash of symptoms a custody covid-19. an infected person coughs or sneezes, seconding droplets through the air. somewhere nearby say up to six feet away breathes those droplets and can become infected. the virus can also spread hand to hand. you touch an object that has the virus on it, and then touch your mouth, nose perhaps, even your eye.

scientists are studying how long the coronavirus can survive on various surfaces, or whether there are other ways it can spread. just two days ago, a study from china of nearly 1100 patients with covid-19 reported a mortality rate of 1.4%. that means of every thousand people infected, 14 will die. the death rate with flu is about 1 in a thousand. but some scientists feel the actual rate with coronavirus may be lower and in fact closer to flu because there are likely many cases we don't know about, either because they're mild or the patients have no symptoms at all. also, people who are older or who have other ailments such as diabetes or lung disease appear to be at greater risk for getting a severe case of coronavirus. but for some reason, children seem to be relatively spared. right now there is a shortage of testing kits for the virus. when more testing is available, we'll get a better idea of how widespread this virus is. we'll be able to screen communities for both active infection and evidence of past infection. here in the united states, we're starting to hear about a small

number of cases of covid-19 from what's called community spread. that means there is no clear source of infections such as travel to an affected region or close contact with a patient. this is not at all surprising, especially since people will likely not have effective immunity to this new type of coronavirus. we should expect the number of these community-spread cases to continue to rise. vaccines are being developed at record speed, and several will begin clinical testing in the coming weeks, but it will take time to confirm their safety and their ability to protect against the virus. so they're not expected to become widely available for at least a year. antiviral drugs and other therapies are also being studied, but for now the main treatment involves supportive care, including breathing tubes in cases of severe lung damage. where does that leave us? what can you do to protect yourself? here are a few suggestion. get the flu vaccine and get your family protected. the flu can mimic coronavirus and make you think you have

covid-19 when you don't. now stuff your mother could have told you. wash your hands, including the tips of your fingers for 20 seconds. i know that's a long time, but do the best you can. keep your hands away from your face. cough boo the crook of your arm, not into your hand or worst of all right into the air. stay home if you're sick. you're not doing the boss a favor by coming to work and making everyone else sick. stay informed. a great source of information is the cdc website, cdc.gov. it's especially helpful for information and advice about travel. what about those surgical face masks so many people are wearing? they may give some partial protection by catching droplets containing virus, but the virus is so tiny, it can go right through the mask or around it. if you're sick, a mask might help protect others, but the cdc does not recommend it for routine use. what should we expect in the future? since then is a new type of coronavirus, it's very difficult

to predict. respiratory viruses often like cold, dry air and may possibly start to die down with warmer, moister weather. but we don't know that for sure. and there could be more waves of infection to come. bottom line, there is no way of knowing right now how long coronavirus will remain a problem. one thing we should definitely expect is anothe outbreak of another type of virus. covid-19 is just the latest example of a deadly viral disease jumping from animals to people. arrest sars, mers and ebola are others. we need to study why this is happening. in asia, deforestation may have increased contact between humans and bats, which could carry the virus that causes sars or covid-19. and we must think globally about how to prevent and respond to future outbreaks. >> the "cbs overnight news" will be right back.

♪ >> reporter: since the beginning, humankind has been obsessed with tracking time. ♪ take time >> reporter: and nearly every civilization has tried to squeeze that time into an accurate calendar. but for thousands of years, we were missing one crucial element. ♪ time keeping on slipping, slipping, slipping ♪ >> reporter: the leap year. >> i think that time is very confusing sometimes when you have to thigh about it. >> reporter: jackie is an astrophysicist at the american museum of natural history's hayden planetarium in new york city. when people think about the day, february 29th, what should they think about? >> we're placing a human construct around what is an astronomical phenomenon of the earth moving around the sun. so it's kind of a celebration of the fact that we'd really like to be better timekeeper, and we

haven't quite figured out how to do it correctly. >> reporter: the calendar we juice uze includes leap years because of how long it really takes the earth to orbit the sun, i which is not 365 days. it's about 365 and a quarter. people are fascinated by this. >> it's a fascinating topic. what can be more fascinating than how we fit in with time and our relationship with the universe. >> reporter: alexander boxer is the author of a new book, "a scheme of heaven", to today's big algorithms, including how we organize dates. when people think heap year today, what should they think of? >> they should think our calendar is a fascinating product of many civilizations, each of who tried to contribute a piece to make sure we stay in sync with the seasons. and the leap year marked the end of the attempt to sync up the cycles with the monday night football and the acceptance of a

calendar that was purely solar. >> reporter: it was the egyptians who first made the leap around 2500 b.c. but it wasn't until julius caesar until the calendar began to take the form we know today. it still wasn't quite right. that led to the gregorian calendar, which set the leap year pattern we've used since the 16th century. but some think it's high time for another big change. you guys have been working on this calendar for how long? >> decades. and so far nada. >> reporter: interdict henry and steve hankie, professors at johns hospital kins university and the current biggest backers of a brand-new calendar, one that eliminates leap years and standardizes the days and weeks to always be the same each year. >> january 1 is always on a monday, forever. >> forever? >> forever. >> reporter: in addition to starting every year on a monday,

the hankie-henry permanent kald worry also set your birthday and the holidays to the same day of the week every year, except for october 31st, which along with all friday 13th would vanish. in place of leap year, every five or six years an extra week is inserted at the end of december, sort of an extended christmas vacation. variations of this idea have been discussed for more than a century, but to no avail. there is no such thing as a perfect calendar. you just think this is better than what we have now. >> ours is very close to perfect. >> the thing jerks around by a day or two. and think how many people around the world and sports schedules and all these things that jump and jerk and jerk around. >> reporter: but aren't quirks and eccentricities part of the human existence? >> we could make things worse and then you'd be happier. >> well, they cost a lot, though. >> reporter: henry and hankie say their calendar is more efficient because it makes

school calendars more predictable and evenly divides business quarters which would simplify financial calculations. they say it would save on average every person $575 a year. what you're saying is i'm not going get $575 in my pocket if this change happens, but it is going to save both workers and companies money and time? >> general efficiency. it's real. >> reporter: if it's real, why do you think it hasn't changed until now? >> people are in a rut, and it's very, very hard to change your thinking. >> reporter: besides ditching leap year, hankie and henry also want to eliminate time zones. >> it's already implemented for all the airline piles. a they use greenwich time. if they're fry flying across the mississippi, they change their watch and change. it's ludicrous. >> i wish you guys got passionate about this. >> look, i'm stuck on the planet with the rest you have. and i see us having a silly system here that is costing us. >> it may be costing us money.

the question is whether a new calendar would cost us some of our identity. either you can see the calendar as this pristine sense of how the universe works, or you can see it as a human product that really represents the contributions of people over thousands of years to try and incrementally improve our knowledge of where we are in the universe. >> does it make sense to get rid of a leap year or leap seconds? >> calendar changes people i think are resistant to because of what it means from the infrastructure of how we all live our lives. the earth doesn't really care what day you call it. it knows where it is. it's going around the sun, doing the thing it always does, and i really just want to know where is the earth in reference to the sun right now. ♪ take time >> reporter: in new york city, jeff glor, cbs news.

history was made in kansas. the state just wrapped up the nation's first ever all female wrestling championships. jamie yuccas spoke to some of the happy winners. >> reporter: she's a country girl, no stranger to hard work. and nothing can keep her down. on the farm -- >> get there quick. >> reporter: or anywhere else. >> time! >> reporter: 18-year-old nicky moore has been wrestling boys for years, one of five girls on the nickerson high varsity squad. it's the kind of confidence that wasn't always there. moore still remembers being bullied as a kid. >> i was really quiet. i kind of walked with my head down. i stayed by myself. >> reporter: why? >> i didn't think i was good enough to be where i am today.
