The total cases of the 2019 novel coronavirus detected in California have risen to six as of Monday, February 3.

There are 11 total confirmed cases in the United States, none of these are in Santa Barbara County.

Ventura County released a statement that two people were tested for the virus. One of the tests came back negative while results are still pending for the other test. Currently, there are no confirmed cases of the coronavirus on the Central Coast of California.

On Sunday, a husband and wife were diagnosed with the virus in San Benito County. The husband traveled to Wuhan, China, where the virus is believed to have originated, but the wife contracted the disease in the second person-to-person transmission in the U.S., according to a statement from health officials. The husband was screened at San Francisco International Airport on January 24 and was without systems, although he and his wife developed them days later. Both have remained in their home since the diagnosis.

Another case was reported in Santa Clara County after a woman traveled from Wuhan to the area. This is the second case in Santa Clara County, however, officials state the two cases are unrelated, CNN reported

Earlier this week edhat reported two cases in Southern California, Los Angeles and Orange counties.

The Santa Barbara County Public Health Department (SBCPHD) is working closely with the California Department of Public Health and the CDC to respond to the outbreak of this novel coronavirus. SBCPHD is communicating with local health care providers on how to safely and effectively evaluate ill people who have been to China. They are providing updates on their website.

The coronavirus has caused 361 deaths and more than 17,000 people have been diagnosed, most of which are in China. All deaths related to the virus have taken place in China except for one reported in the Philippines. The virus has spread to more than 20 countries and territories.

A global emergency was declared last week by the World Health Organization and the Trump administration announced a public health emergency Friday while evacuating citizens and personnel from China. A temporary travel ban was approved to bar foreigners from entering the U.S. if they have been to China in the past 14 days, with exceptions for the immediate family of American citizens and permanent residents.

Two cases of the 2019 novel coronavirus that originated in China have been detected in Los Angeles and Orange counties.

The outbreak of this respiratory illness started in Wuhan, Hubei Province, China. It causes some patients have a mild illness while a small number have had a more severe illness, and a few have died. Cases have been diagnosed in fourteen countries and now in California, Washington, and Illinois.

Health officials confirm the cases in Southern California came from people who recently traveled to Wuhan. A returning traveler who landed in Los Angeles County is receiving medical treatment. The patient in Orange County is in good condition and is isolated at the hospital. 

Health officials state the risk of local transmission remains low and anyone who has come into close contact with the patients has been contacted.

Coronaviruses are a large group of viruses that are common among animals and humans. In rare cases, animal coronaviruses can be transmitted from animals to humans. This novel coronavirus is a newly discovered coronavirus that has not been previously detected in animals or humans. The source of the novel coronavirus is not yet known.

Early on, many of the patients in the outbreak in Wuhan, China reportedly had some link to a large seafood and animal market, suggesting animal-to-person spread. However, a growing number of patients reportedly have not had exposure to animal markets, suggesting person-to-person spread is occurring. At this time, it is unclear how easily this virus is spreading between people, according to the Santa Barbara County Public Health Department.

Typically, human coronaviruses cause mild-to-moderate respiratory illness. Symptoms are very similar to the flu, including: runny nose, headache, cough, sore throat, fever, shortness of breath.

Most people with illnesses due to common coronavirus infections recover on their own. There are no specific treatments but for patients who are more severely ill, hospitals can provide supportive care. 

The Santa Barbara County Public Health Department (SBCPHD) is monitoring the situation and working with partners to identify any possible cases. No cases have been reported in Santa Barbara County.

If you have traveled to China between December 15, 2019 and now, and you have become ill with fever, cough or shortness of breath, call your health care provider. Please be sure to tell your health care provider about your travel history.

N95 masks or equivalent. It is interesting that many health workers wearing masks have been infected by aerosol particles entering their eyes; wrap-around glasses are indicated as well. Was your hands regularly. Understand that many hand sanitizers don't kill viruses. It appears that the virus can remain viable for 5 days on surfaces; touch the surface and then any mucous membrane or eyes and Bam! Incubation period appears to be 1-14 days, and people are contagious during this time of no symptoms, which makes detection and containment particularly difficult. I'll be flying back to CA in 2 weeks and am loathe to enter a tightly sealed plane, mask and glasses or not. 15 hours flying in re-breathed air....arg! Of course if this continues to escalate, I'll cancel the flight. This is one gift I care not bring to my 92 year old mother.

From everything I have read the past 24 hours, the N95 and other masks do nothing because they are NOT airtight. People who wear them will itch their faces, lift the mask to touch the face, rub their eye(s), etc. Air can also flow from the "open" sides" and that makes the mask ineffective. The key is thorough hand washing for at least 20 seconds using warm to hot water & soap! Hand sanitizer works too.

As I stated , many hand sanitizeres do NOT work on viruses. A well fitting N95 mask does a very good job, but, agreed, it isn't 100%. Same with the glasses; they reduce exposure to a high degree, but are not 100%. I also agree that folks who itch and touch their mouth or eyes are likely toast. This is a multi faceted problem requiring a similar response, not simply washing hands correctly.

Huh. I was wondering why I had seen two different Asian people wearing masks in our local supermarkets. Just within the past week. Now I know why.

The big thing with this one is being contagious for several days but not exhibiting any symptoms. The cat is already out of the bag, and now we’ll be both spectators and participants in the drama.

2pm Sunday Jan 26th. Home Depot completely sold out of any and all masks. I personally saw at least three groups of Asians wearing masks that were in the store asking about the purchase of additional masks. Response from Home Depot: demand is too high to predict when supplies will be available...first come, first served. Yikes. Anyone know when and where Direct Relief will be providing masks to the community as they do during fires ?

I suspect that most interest is to be prepared just in case, rather than paranoia that it is ubiquitous. It is also relevant information to anyone who travels, especially by air. The unknowns of a "novel" virus make it a scary matter.

No article that claims that "The novel coronavirus is in the family of viruses that causes the common cold" is an excellent article. The common cold is caused by a rhinovirus / genus Enterovirus / family Picornaviridae / order Picornavirales . OTOH, coronavirus / genus Orthocoronavirinae / family Coronaviridae / order Nidovirales ... they not only aren't in the same family, they aren't even in the same order.

Stay home, close your windows, close your eyes, don't get out of bed! Come on, people. There's no evidence that any of the US cases have infected anyone else. The person in Washington is almost fully recovered and the one in Chicago is getting better every day. Being cautious in cold/flu season is smart, but paranoia is not necessary. Wash your hands, try not to touch surfaces that many people touch, and if you do, keep your hands away from your face and wash them again! And keep washing them.

The reported death rate so far is about 3% which is higher than regular flu at 0.1%. We’ll see if that holds here or not. We’ll also see if the transmission rate is the same here or not. It’s just getting foothold here. Preparation, not paranoia. Just before Christmas our son came down with regular flu. We basically quarantined him in his room, and we washed our hands and sanitized all door knobs and etc about every 5 min it seemed, and none of us got sick. Fastidious handwashing, don’t touch your face, and carefully plan your public excursions if the case count starts rising in the state.

The critical part is if the bug mutates into something more dangerous over time. If it does, it could get very interesting.

An interesting note about door knobs and hardware: Hardware made of uncoated copper or plated with sterling silver, will not allow bacteria and viruses to survive. I expect that this was a major reason for eating and drinking from silver in old times. Obviously, not all could afford to eat from silver and those that ate from pewter got dosed with lead. Silver was especially important when utensil cleaning was minimal or water was not available. Some hospitals are changing out the stainless hardware for copper, because while stainless steel may LOOK clean and modern, it is a haven for germs. Not wanting my lips to touch airline cups, I have made a sterling silver straw to use on my dreaded upcoming flight. (along with sanitizer wipes, mask, glasses etc) Yes, my mask will be slightly open when I drink, but I'll not breathe until the straw is out. As if back to back nine hour and a 5 hour flights were not already bad enough!

While my dad was a teacher, (they're all rich), my grandmother was a silversmith, so the answer is yes. There is a whopping $10 worth of silver in that straw, enough to retire on.

The ignorance level on this story is shocking. Clearly no one here reads international news. From CNN:
Rising toll: 82 people are dead and more than 2,700 cases have been confirmed in mainland China, as the Wuhan coronavirus continues to spread throughout Asia and the rest of the world.
China on lockdown: Nearly 60 million people have been affected by partial or full lockdowns in Chinese cities as the country's government steps up its response.
Global spread: There are more than 50 confirmed cases in 13 places outside of mainland China, including at least five in the United States.
Contagious before symptoms: People can spread the virus before symptoms show, China's health minister said Sunday, complicating efforts to contain the outbreak.

There are confirmed cases in the US, 2 just 2 hours south of here.
Wear masks, and N95 are the most effective, though not bullet-proof. Wash hands, avoid contact and crowded places. It's spread by touch and then you put your hands to your eyes, nose or mouth; it's also spread by coughing and kissing.
And, no China's regime has totally failed to quarantine it in time or catch it, so it is spreading into Europe and America.

Possibly important question I have not seen addressed anywhere. How long can this virus survive on surfaces? (A feline corona virus, for example, is described as being able to survive for possibly 7-8 weeks.) Many online purchases nowadays on sites like Amazon or Overstock, etc. are often shipped via MAIL in a matter of days from mainland China - not sitting for weeks or months in containers at the port of Long Beach. So, could our many purchases coming via mail from China represent a "Trojan Horse," allowing for more inadvertent transmissions? Scientists among you, please pontificate...

Because the viral payload, RNA in this case, is packaged into a capsid, it is fairly well protected from things that break down nucleic acids (RNA and DNA). The capsid is a protein shell that functions in both protection and delivery. Dehydration isn't usually a concern for nucleic acids. For example, I've received DNA plasmids from fellow researchers that have been spotted on to blotter paper and shipped to me in the mail, from as far away as Australia. A quick soak in TE buffer and I have rehydrated and completely viable DNA. Exposure to UV light is usually the real thing that damages nucleic acids, so those pieces of blotter paper I received in the mail have been wrapped in foil. Other things that could affect the viability of viruses on the surfaces are the other things inside the viral capsid. Some viruses require a little help to get started once they enter a cell, so the payload can include some important enzymes that can degrade a little more quickly than nucleic acids. However, corona virus is a positive sense RNA, which means that for the most part it's good to go once it enters a cell and can use your enzymes to translate its products and replicate it. Hope that helps.

@CURMUDGEON, sorry but while I was "pontificating" and trying to compose a succinct answer regarding things that mitigate the survival of viruses on surfaces, I think I failed to answer your last question. Yes, it's possible. If an a highly contagious person in a warehouse in China could cough and send infected droplets of saliva on to an item, and if that item were boxed in another container it would be protected from UV and survive the trip to the US. This is provided that it remains protected from UV light and isn't exposed to extreme temperatures. However, how long it takes from that initial cough to the time the item ends up on your doorsteps is unknown to me. There is the trip across the Pacific, and then it may sit a while until it clears customs. Others can debate, and I can only speculate that this takes more than "a matter of days". I ordered an odd lightbulb that shipped from England last month. It took several weeks to get here via Royal Mail. I suspect that many of the made in China items you order from Amazon have been sitting here in the US for weeks or months. So while I maintain that it's possible, I don't think it's probably or a least not as worrisome as infected humans in terms of containing this outbreak.

Thank you, CHEMICALSUPERFREAK. Answer appreciated. I was asking because we have received items ordered from the popular online sites that were, in fact, mailed in 'China Airmail Post' packs from mainland China and not from a U.S. warehouse, the most recent of which came from 'Gongshu District, Hangzhou,Zhejiang, China, GongShu Qu.' Came in a packet that said 'U.S. Postal Service e-Packet China Post.'

N95 masks have a pore size of 0.3 micrometers. For comparison a coronavirus has a diameter of about 100 nanometers, which is 0.1 micrometers. So the holes (pores) in an N95 mask are 3 times larger than the virus. If you are wearing a properly-fitting N95 mask and happen to walk through a cloud of individual coronavirus particles you will end up inhaling many of them, because the virus particles simply pass through the mask’s pores. Masks worn by infected people however, are useful because this way the mask stops virus-containing droplets from the infected individual from entering the environment.

ChemicalSuperFreak Jan 28, 2020 12:38 AM

Actually, the reported diameter of the corona virus capsid is around 120-125 nm, so the 0.3 µm pore size of the mask is only about 2.5 times larger. Still, point taken. However, the mask is not some infinitely thin barrier with 0.3 µm holes in it. It’s a thick fibrous material. The estimate (from the FDA for example) is that it will filter 95% of 0.3 µm sized particles. Furthermore, the size of droplets from a sneeze, the type that would remain airborne at distances of around 2 meters are about 50-100 µm. Let’s just pick a small 50 µm droplet and compare that to the 0.3 µm. In that comparison, the N95 mask should filter at least 99% of those 50 µm sized droplets that try to pass through the material. The real weakness of those masks is that they don’t form the best seals on some (if not many) faces, particularly young children and people with facial hair. So the weakness is not in the pores size compared to viral diameter. The weakness is in the potentially large gaps at the periphery of the mask itself.

All of those "CDC-confirmed" cases are confirmed via gene sequencing from samples sent to them. You could use an electron microscope to get an image of the virus, and that would tell you the difference between the influenza and corona virus as well. But the drawback of an electron microscope is that you cannot differentiate between the "common", SARS, MERS, and now novel-corona viruses because they look similar, with distinctions only at the genetic level. Otherwise the best that local hospitals can do is guess based on symptoms and a patient history, then send those suspected samples for genetic testing.
