Coronavirus Covid-19 Global Cases by John Hopkins CSSE

 

Reference: Dong E, Du H, Gardner L. An interactive web-based dashboard to track COVID-19 in real time. Lancet Infect Dis; published online Feb 19. https://doi.org/10.1016/S1473-3099(20)30120-1.

 

Background

On December 31, 2019, the World Health Organization (WHO) was informed of an outbreak of “pneumonia of unknown cause” detected in Wuhan City, Hubei Province, China – the seventh-largest city in China with 11 million residents. As of January 23, there are over 800 cases of 2019-nCoV confirmed globally, including cases in at least 20 regions in China and nine countries/territories. The first reported infected individuals, some of whom showed symptoms as early as December 8, were discovered to be among stallholders from the Wuhan South China Seafood Market. Subsequently, the wet market was closed on Jan 1. The virus causing the outbreak was quickly determined to be a novel coronavirus. On January 10, gene sequencing further determined it to be the new Wuhan coronavirus, namely 2019-nCoV, a betacoronavirus, related to the Middle Eastern Respiratory Syndrome virus (MERS-CoV) and the Severe Acute Respiratory Syndrome virus (SARSCoV). However, the mortality and transmissibility of 2019-nCoV are still unknown, and likely to vary from those of the prior referenced coronaviruses.

 

Infected travelers (primarily air) are known to be responsible for introductions of the virus outside Wuhan. On Jan 13 Thailand reported the first international case outside China, while the first cases within China, but outside of Wuhan were reported on January 19, in Guangdong and Beijing. On January 20, China’s National Health Commission (NHC) confirmed that the coronavirus can be transmitted between humans. On the same day human infections with 2019-nCoV had also been confirmed in Japan and South Korea, and the following day cases in the U.S. and Taiwan were detected in travelers returning from Wuhan. On January 21 multiple provinces in China were also reporting new cases and infection was confirmed in 15 healthcare workers, with six fatalities reported. Additional travel cases have now been confirmed in Hong KongMacau, Singapore and Vietnam. On Jan 22, a WHO emergency committee convened to discuss whether the outbreak should be classified as a public health emergency of international concern (PHEIC) under International Health Regulations, but were initially undecided due to lack of information, before deciding against the declaration.

 

Of immediate concern is the risk of further transmission resulting from high travel volumes and mass gatherings in celebration of the Chinese New Year on January 24. In attempts to mitigate local transmission within China, unprecedented outbreak control strategies were implemented in (initially) three cities. On 23 January 2020, Wuhan suspended  all public transport and air travel (in and out of the city), placing all 11 million city residents under quarantine. On Jan 24, Huanggang and Ezhou, cities adjacent to Wuhan, will also be placed under a similar quarantine, with more cities in China now following suit. Further, many cities have canceled Chinese New Year celebrations.

 

As Wuhan is a major air transportation hub in central China, various measures have been taken on a global scale to mitigate international spread. Targeted airport screening of passengers traveling from Wuhan was initiated as early as January 1 in Hong Kong and Macau. Taiwan, Singapore and Thailand starting to screen arriving passengers on January 3. In the U.S., the CDC began entry screening of passengers on direct and connecting flights from Wuhan to the three main ports of entry on January 17, 2020, with Atlanta and Chicago soon to be added. On January 23 the U.S. CDC raised its travel notice for Wuhan, China, to the highest of three levels. Additional Pacific and Asian countries including Malaysia, Sri Lanka, Bangladesh and India are now also conducting targeted passenger screening at airports.

 

GIS Dashboard  (Updated February 11, 2020)

In response to this ongoing public health emergency, we developed an interactive web-based dashboard (static snapshot shown above) hosted by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University, to visualize and track reported cases in real-time. The dashboard, first shared publicly on January 22, illustrates the location and number of confirmed COVID-19 cases, deaths and recoveries for all affected countries. It was developed to provide researchers, public health authorities and the general public with a user-friendly tool to track the outbreak as it unfolds. Further, all the data collected and displayed is made freely available, initially as google sheets, now in a GitHub repository, along with the feature layers of the dashboard, which are now included in the ESRI Living Atlas.

 

The dashboard reports cases at the province level in China, city level in the US, Australia and Canada, and at the country level otherwise. From January 22-31 the entire data collection and processing was managed manually. During this period the number of updates were typically conducted twice a day, both morning and night (Eastern Time). As the outbreak evolved, the manual reporting process became unsustainable, and on February 1, we adopted a semi-automated living data stream strategy. Our primary data source is DXY, an online platform run by members of the Chinese medical community, which aggregates local media and government reports to provide COVID-19 cumulative case totals in near real-time at the province level in China and country level otherwise. Every 15 minutes, the cumulative case counts are updated from DXY for all provinces in China and affected countries and regions. For countries and regions outside mainland China (including Hong Kong, Macau and Taiwan), we found DXY cumulative case counts to frequently lag other sources; we therefore manually update these case numbers throughout the day when new cases are identified. To identify new cases, we monitor various twitter feeds, online news services, and direct communication sent through the dashboard. Before manually updating the dashboard, we confirm the case numbers using regional and local health departments, namely the China CDC (CCDC), Hong Kong Department of Health, Macau GovernmentTaiwan CDC, European CDC (ECDC), the World Health Organization (WHO), as well as city and state level health authorities. For city level case reports in the U.S., Australia, and Canada, which we began reporting on February 1, we rely on the US CDC, Government of CanadaAustralia Government Department of Health and various state or territory health authorities. All manual updates (outside mainland China) are coordinated by a team at JHU.

 

We are currently in the process of conducting additional modeling of this emerging outbreak, and will update this blog post with the results soon.

Our team (Business Productivity) has been tasked with a fast implementation of work-from-home technologies and policies, which we began piloting two years ago for our institution. We had intended it for use by our remote employees within IT but we are now expecting the majority of our workforce to be working from home at one point or the other during the next few months. We began piloting Microsoft Teams two years ago and have now adopted it throughout the college without much of a formal introduction.

It's spread to a few new countries today- Andorra and Indonesia, after spreading to the Dominican Republic, Ecuador, the Czech Republic and Armenia over the weekend.  The number of cases doesn't seem to be rising that fast, but I imagine a lot of that is because testing procedures have been so terrible, combined with multiple governments seemingly working to minimize negative news.  For a virus that everyone says is no worse than the regular flu, I'm not sure why controlling information is such a high priority.

Add Portugal, Senegal and Latvia for new cases.

An article from today. You know what I find interesting?

 

"By comparison, influenza — known as the common flu — has infected as many as 45 million Americans since October and killed as many as 46,000, according to estimates from the Centers for Disease Control and Prevention."

 

But if you look at their raw numbers from September 30th, 2019 - February 15th, 2020 only 3,482 people have died from influenza. An amazing 14,518 - 42,518 will have to have died in the last two weeks for their estimates to ring true. So what in the world is going on here? Why is the Washington Post reporting that? Why is the CDC still publishing that? Why are you all falling for the fear porn again? SARS, Avian Flu, Swine Flu, West Nile Virus, Ebola, Zika, and now Coronavirus. Every 2-3 years you're manipulated under fear of death. When will you call out the Boy Who Cried Wolf?

The flu's death rate is .1%, the coronavirus 1.7-2.5 percent. 

 

That is an enormous difference, and containment is very difficult.

 

This isn't fear porn. 1.7-2.5 percent of 45,000,000 would be nearly a million people. That's a whole different level.

 

And there are vaccines for the flu; nothing for coronavirus.

Great thought process and i would normally be right along with this logic. However, pandemics are real. Just because you didn’t end up getting SARS doesn’t mean that government didn’t take it seriously. The Novel Coronavirus is something never seen before. I and many people believe it to be man-made. Scientists notice there are 3 points in the RNA of the virus that have been spliced and edited.  It sounds like it has mutated a bit already. 
  Whatever is hitting Italy, Iran, and China seems pretty aggressive.  I don’t recall people keeling over in the streets with other diseases. I don’t recall the secrecy countries are going to keep a lid on how serious this is. There is no open news about what is going on in Wuhan.  There were credible reports of hundreds of people dying and since they weren’t tested never got classified as dying from this virus. I think Wuhan is still shut off. 
   Its better to treat this very seriously and limit its quick spread. Better to allow time to develop a vaccine.

We really don't know the fatality rate of coronavirus.  Yesterday, WHO sad 3.4% of confirmed cases, but who knows how many milder cases there have been, or how many deaths there have been that were either not reported or assigned different causes.  Covid-19 was in Washington for 6 weeks, and no one was testing for it prior to a week or so ago, and we've barely tested anyone nationally yet.  Outside of China, which is the only country seeing significant declines- conveniently- cases are exploding everywhere else.  New cases reported now in Poland, Faroe Islands, Gibraltar and Saint Bethelemy. Aside from Poland, we're getting into some small, isolated places.

There is no evidence this was man-made and I haven't seen anything anywhere that suggests its RNA or anything else has been tampered with artificially. It's been traced back to human-animal interaction. 

The government secrecy is more a function that people in many countries have voted in nationalistic populists or authoritarians who already have a propensity to want to isolate their nations and consolidate power in their respective executive branches.  Pretending like this is no big deal, or underreporting cases, is safer for the status quo than admitting that they don't have things under complete control.  

As for there being far more cases than are being reported, it's hard to say.  We assume nations like China are doing that, but we can't say with 100% certainty.  In the 1918 flu, China did relatively well compared to the rest of the world, with the thinking that the virus had swept through the population at some point previously, raising their immunity before it arose with a vengeance globally at the end of 1917.  

We probably won't know the full scale of things for months, if not a few years.

The right wing conspiracy world is all about the virus coming out of a lab in Wuhan. There is a correlation of researchers from Canada that were caught sending SARS virus samples to the lab there. Whether it was unknowingly released or accidentally released is obviously unknown. I really have no doubt they were testing this disease on animals. So researchers can say they have a 90% confidence that it came from animals.  I would wait to hear from bioengineers that have looked at and reviewed the RNA. Supposedly the full RNA was released online by another lab in China in January.

Why is that a right wing conspiracy? I mean, I can't stand those nutters in general, but clearly labs have created viruses before i.e. Sars 2.0 and 2009's H1N1.

We don't know what the COVID-19 death rate is. Considering some people carry it around with zero symptoms I'd imagine we'll never have a true rate.

 

That's exactly what fear porn is. Extrapolating across an entire population with inaccurate base figures. Comparing it to 1918 is fear mongering at its best. Before modern antivirals. Before modern antibiotics (more people actually died of bacterial pneumonia than the flu). Before modern sanitation. Before modern hygiene. I mean come on.

 

Vaccines with 50% efficacy rates. Less efficacy than simply supplementing Vitamin D.

Wanna hear a conspiracy? As high as 95% of the "Spanish Flu" deaths were from bacterial pneumonia. That should have been clear since the "Spanish Flu" attacked young, healthy people in their prime; the opposite of whom the flu kills i.e. the elderly and otherwise immunodeficient. The first cases of the "Spanish Flu" trace back to Fort Riley in Kansas on March 4th, 1918. What happened at Fort Riley from January 25th - June 4th, 1918? An experimental vaccine for bacterial meningitis was administered to 3,700 volunteers. This was one of 16 training locations for World War I infantry. The Rockefeller Institute also sent their vaccine to European allies though their testing of soldiers isn't as well documented. 2+2=5?

i have read in many places that it came from the wuhan lab workers selling bats and other animals to wuhan wet markets for side money. 

 

who knows? but i think so far they do know or highly suspect it came from bats in the wet markets.

 

btw chinese wet markets can be nasty. they leave stuff out in the open too long. "just keep spraying water on it it will be ok" lol. riiiiight.

I was on a flight Friday and a good 10+ people on the plane had masks.  Absolute morons.  It is not transferred via air.  And even if it were, I doubt these people got their masks fitted to be *exactly* airtight.  Panic is real out there.

If any of them were sick, it would be beneficial for them to wear a mask to protect others. But most (probably all of them) of them were probably wearing them to protect themselves.

The thing that keeps any infectious disease, or any crisis, from turning into a disaster is when people take it seriously, but don't panic.  Just ignoring it doesn't make it not a problem, and going nuts and doing irrational things only makes it worse.

Correct - I don't think any of them were actually sick.  This was all before a lot of the warnings came down that masks don't really serve any purpose, unless you're a healthcare worker or you're sick.  But they did a study on people who don't regularly wear masks and then do so and they end up touching their face MORE because they constantly are adjusting it.

There is a report from NY of a guy testing positive, being told to self-quarantine... and then he goes to a party and now 1000 people are being monitored.  People are dumb, and it's beyond containment. 

In Europe, the numbers are exploding. Today, 4 additional countries reported their first cases- Palestine, South Africa, Bosnia and Herzegovina and Slovenia.

I normally don't get freaked out by these things, but yesterday it kinda hit me and now I can't stop thinking about it. I hope this is somehow contained. I'm worried it will become a part of "cold and flu and coronovirus season" but if you get COVID-19, you're much worse off. 

 

I'm just worried about my parents 😞 . 

 

I'm encouraged by the statement of jmecklenborg that it might not become a big thing, but I was reading this Atlantic piece and well....I kinda am leaning towards this being the correct scenario: https://www.theatlantic.com/health/archive/2020/02/covid-vaccine/607000/

UPDATE - the airport I flew into has confirmed someone who arrived there on the day I did (EDIT - he arrived a day later, but I went back through that same airport on the 3rd) has been confirmed to have COVID-19 (he apparently was in Italy a few days before) *and* also was skiing at the resort I went to.

And sh!t like this is happening, despite that Pence says everyone coming from Italy is being screened....

 

 


"Nearly every problem that we have in the USA -- unaffordable health care, prison overpopulation, hyper militarization, climate change, racism, gun violence, poverty, poor education, urban sprawl and others -- cannot be positively addressed because bribery and conflicts of interest are legal under campaign finance laws which protect the uber-wealthy and the narrow self-interests who grossly benefit from our afflictions."

Total cases have surged past 100,000 and are far outweighing recoveries now (most of the recoveries were from China, if one believes their numbers).  6 new places have reported their first-  Costa Rica, Bhutan, Cameroon, Slovakia, Serbia... and Vatican City.  Cases in Europe continue to rise rapidly, and the US response remains an unmitigated disaster. Only 75,000 of the promised 1 million tests have managed to be delivered, and yet Pence suggested 4 million would be available next week.

What are you talking about? Covid-19 IS transmittable via the air.  If an infected person sneezes or coughs and you inhale that you could get it. That's why its so highly contagious as we can't control who around us coughs or sneezes and when you're on a plane you can't really run away.  Yes, planes have HEPA filters but a lot of that sneeze or cough circulates around the plane before it gets sucked into the filtration system.  If you've been around sick people please self-quarantine yourself just to be safe to not spread it around to others.

I mean, I'm in good health so I'm not too worried if I get it.  I think the average age of the person who contracted it in Italy is like 83, which suggests to me that younger people just think it's the common flu and aren't getting tested.  I could be wrong about that, though.

 

I have been washing my hands like crazy even before finding out I was in the same airport as a person with COVID-19.  But yeah, I'm definitely running straight to an urgent care center the minute I notice anything remotely resembling the flu.  Thankfully, we have some masks from when we bought a bunch of paint supplies.

No I think you’re correct @DarkandStormy. Young people are infected but the symptoms are so mild they aren’t seeking out testing for it. Which on the downside means there are many people with little to no symptoms who may be spreading the virus unknowingly.

 

South Korea is doing the most widespread testing of anybody, and as a result is the mortality rate is hovering around 0.5%, which is probably the most accurate data so far.

A place we do business with in another state confirmed the owner and his wife had the coronavirus and the owner was in the hospital for 3-4 weeks recovering from severe pneumonia.

 

They would be 2 of the 4 confirmed cases in that state if there is only 4 confirmed cases. The wife didn't really get sick.

 

They only traveled from an inland area of California from Los Angeles, fairly close to Las Vegas (you can probably guess the area) for a 1 week vacation and flew back a week later so the time frame on this is about 5 weeks back from the start of the vacation. You don't think this virus is going to be everywhere soon you are sorely mistaken, IMO!!

From what I've read, there really aren't any people who are asymptomatic entirely.  Everyone eventually develops some symptoms, but obviously some are much more severe than others.  In the meantime, they're spreading it, as you say.  

 

As for SK, the rate of 0.5%-0.7% is still 5x-7x more deadly than flu.  Of course, not every country is going to have the same fatality rate, either.  You have to consider infection rates, health of the population, average age of the population,  security procedures, quality of health systems in place, etc.  I think SK is the best case scenario, but it probably won't be the common one.

It’s no surprise that face masks are in short supply—despite the CDC specifically not recommending them for healthy people trying to protect against COVID-19. “It seems kind of intuitively obvious that if you put something—whether it’s a scarf or a mask—in front of your nose and mouth, that will filter out some of these viruses that are floating around out there,” says Dr. William Schaffner, professor of medicine in the division of infectious diseases at Vanderbilt University. The only problem: that’s not effective against respiratory illnesses like the flu and COVID-19. If it were, “the CDC would have recommended it years ago,” he says. “It doesn’t, because it makes science-based recommendations.”

The science, according to the CDC, says that surgical masks won’t stop the wearer from inhaling small airborne particles, which can cause infection. Nor do these masks form a snug seal around the face. The CDC recommends surgical masks only for people who already show symptoms of coronavirus and must go outside, since wearing a mask can help prevent spreading the virus by protecting others nearby when you cough or sneeze. The agency also recommends these masks for caregivers of people infected with the virus.

 

Sorry, my point about the premature use of masks in the airport is that it's specifically not a recommended way to prevent the disease from spreading, unless you're already sick.  Pretty sure the CDC also says you're more likely to get it from touching your face than breathing in those droplets through the air.

 

No evidence yet that I've been anywhere near someone who has been sick (it would help if the Colorado authorities would let the public know where this patient stayed and when) other than possibly being on the same 6,800+ acre mountain as this person.
