The video fragment only shows increase in COVID-19 cases, reversing the video's original message to induce panic.
- A terrifying graph shows how the spread of coronavirus overtakes previous epidemics like Ebola, SARS and MERS.
- However, the clip is only part of a longer video – and conveniently cuts off before swine flu surpasses COVID-19.
- The wider context: the coronavirus outbreak remains relatively small and is comparatively non-lethal.

Terrifyingly, the line for the coronavirus skyrockets, leaving those for SARS, MERS, ebola and swine flu far behind.<br></p><p>Alarming? Yes. But not the whole story. As Mark Twain once said: There are three kinds of untruths: "Lies, damned lies and statistics." If he were around today, he might add a fourth: video edits. The 30-second clip is part of a <a href="https://www.youtube.com/watch?time_continue=602&v=..." target="_blank">10-minute video</a> with exactly the opposite message: Do <em>not</em> panic!</p><p>When the video was posted, the coronavirus was less than two months old, and had already travelled from its ground zero—a so-called 'wet market' in the Chinese city of Wuhan—across several continents, infecting more than 40,000 people. It had just killed its 1,000th victim. </p><p>The no-panicking message still holds, even half a month and more than double the number of cases later. As of 1 March, we've passed 86,900 people infected, with just under 3,000 deaths reported. Why? Because context is everything. <br></p>

Not only had it infected the most people after just one day, it had killed two thirds of those. </li><li>By comparison, SARS killed its first victim only after three days (out of 38 people infected). </li><li>By <strong>Day 10</strong>, SARS had overtaken Ebola as the most infectious of the outbreaks (264 vs. 145 patients), but the latter was ten times more lethal (91 dead from Ebola vs. 9 from SARS). At this time, the coronavirus had infected 39 people, killed none, and was still playing in the same minor league as the swine flu and MERS.</li></ul>

Day 262: swine flu dwarfs the other epidemics.
Image: Abacaba<ul><li><strong>Day 20</strong>, and SARS cases are skyrocketing: 1,550 people are ill, 55 have died. That's a death rate of 3.5%. Ebola has affected only 203 people by now, but killed 61.6% of them, a total of 125. Meanwhile, the coronavirus has taken Ebola's second place, but is still far behind SARS (284 infected). At this time, the coronavirus has claimed the lives of just five people. </li><li>But now the coronavirus cases are exploding; by <strong>Day 3</strong><strong>0</strong>, the new virus has infected 7,816 people, killing 204. That's far more infected than any other virus (SARS comes a distant second with 2,710 patients), and significantly more killed (Ebola, though still just 242 people ill, has killed 147, due to its high fatality rate). Meanwhile, MERS is stuck in triple digits, and the swine flu in double digits. </li><li><strong>Day 40</strong>: coronavirus cases (40,553) dwarf those of SARS (3,550). The swine flu (369) has overtaken ebola (243), at about the same level as MERS. Also in terms of fatalities, coronavirus now far supersedes SARS (182), ebola (164) and the swine flu (5). </li></ul><p>About here, the clip cuts out. The editing aims to focus the attention on the exponential rise in coronavirus cases. But as the longer version goes on, the story changes. </p>

That's far more than all the other diseases combined—they have merged into a single line at the bottom of the graph. </li><li>By <strong>Day 150</strong>, swine flu hit 5.2 million patients, with 25,400 people killed. By the time it was declared over, a year later, the outbreak would eventually have infected more than 60 million people and claimed the lives of almost 300,000.</li></ul><p>Swine flu was caused by the H1N1 virus, which also caused the Spanish flu. That outbreak, in 1918/19, infected about 500 million people, or 1 in 3 people alive at that time. It killed at least 50 million people. It was the combination of extreme infectiousness and high fatality that made the Spanish flu such a global, lethal pandemic. <br></p><p>None of the other infectious diseases comes close to that combination. The swine flu, although more infectious than other diseases, was less infectious than the Spanish flu, and also less deadly (0.5%). Unlike COVID-19 or its fellow coronaviruses SARS and MERS, Ebola is not spread via airborne particles, but via contact with infected blood. That makes it hard to spread. Ironically, it may also be too lethal (39.6%) to spread very far. And COVID-19 itself, while relatively lethal (2.4%), is well below the deadliness of the Spanish flu, and does not seem to spread with the same ease. </p>

A recent clinical trial shows that two new drugs are far more effective than current treatments.
- The Democratic Republic of Congo has been suffering a major Ebola outbreak since August 2018.
- In November 2018, a clinical trial began comparing the efficacy of four Ebola treatments.
- Two of those treatments — based on monoclonal antibodies — are nearly twice as effective as the standard treatment.
An illustration depicting how to safely bury people who died from Ebola. Image source: CDC's Center for Global Health<p>The monoclonal antibodies-based drugs were especially successful at curing Ebola when patients took them soon after becoming sick, with Regeneron's drug lowering mortality rates to just 6 percent. But one problem is that most Ebola patients in DRC wait an average of four days before coming to the hospital, which decreases the odds of survival and increases the odds of transmitting the disease — through bodily fluids — to people near them.</p><p>But health experts are optimistic about the new drugs.</p>"The more we learn about these two treatments, and how they can complement the public health response, including contact tracing and vaccination, the closer we can get to turning Ebola from a terrifying disease to one that is preventable and treatable," Dr. Jeremy Farrar, the co-chair of the World Health Organization's Ebola therapeutics group, told <a href="https://www.theguardian.com/world/2019/aug/12/ebola-now-curable-after-trials-of-drugs-in-drc-say-scientists" target="_blank"><em>The Guardian</em></a>. "We won't ever get rid of Ebola but we should be able to stop these outbreaks from turning into major national and regional epidemics."
Quarantines are worth the trouble to keep the next pandemic at bay but they need to be applied intelligently.
- A new essay argues that quarantines are often needed, but require strict guidelines on when they can be used.
- Pandemics are inevitable, and actions that can save lives must be planned now.
- The arguments in this essay will undoubtedly be of use during the next outbreak.
What is a quarantine exactly?<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xODYzMzkwMy9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTU5ODc2Njg5N30.O_NoAoV1sVwKEpmlq6cVRxS6MjWxtU0fzBR9Qls4g8Y/img.jpg?width=1245&coordinates=0%2C0%2C0%2C122&height=700" id="fb3ee" class="rm-shortcode" data-rm-shortcode-id="7779ac5059618e73bbd1697876c8d133" data-rm-shortcode-name="rebelmouse-image" />

The World Health Organization WHO has lost track of 45 people under surveillance, who had been in contact with a patient who contracted Ebola, in Guinea. (CELLOU BINANI/AFP/Getty Images)<p>For the purposes of this paper, isolation and quarantine had two different meanings. As the authors define them: "Isolation separates sick people with a contagious disease from people who are not sick. Quarantine separates and restricts the movement of people who were exposed to a contagious disease to see if they become sick."</p>
Why would quarantine be a good idea? After all, they aren't sick yet!<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xODYzMzkzMy9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0NzI1ODg3OX0.RIT9_b3XhEJ5n5Aohr0PkWCBV7Lv8Y9dhHh6zq1EFT0/img.jpg?width=1245&coordinates=0%2C0%2C0%2C1&height=700" id="7d62a" class="rm-shortcode" data-rm-shortcode-id="4065a9a1ceb5bbb228cdc9cc6daeb0de" data-rm-shortcode-name="rebelmouse-image" />
"Typhoid" Mary Mallon, far left, in quarantine. Her refusal to wash her hands while carrying typhoid fever bacteria may have killed fifty people. She was forced into quarantine for the safety of the public.
(Public Domain)<p>The first argument that the authors make is the obvious one, society benefits a great deal from quarantining a person who might be carrying a deadly disease at a relatively low cost to that society and a moderate cost to the person quarantined. A person who is exposed to Ebola <em>might </em>contract the disease and start spreading it before they are aware of their illness. Quarantines try to prevent this by hiding away anybody who might have been exposed to a disease, even if they are asymptomatic. <br></p><p>This <a href="https://bigthink.com/scotty-hendricks/how-much-we-trust-someone-depends-on-their-response-to-this-moral-dilemma" target="_blank">consequentialist</a> stance is the one typically invoked by governments and state agencies when quarantines are introduced, but the authors don't think it is the best ethical foundation. After all, it might be for everybody's benefit to lock away anybody exposed to the common cold for a week to keep infection rates down. This seems excessive, suggesting that the final answer lies elsewhere. </p>
Personal responsibility<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="a55a6c0e463e3d07dad75d666f5d9b43"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/W3BmxyA3QPQ?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>The authors then argue that, in many cases, the individual exposed to a potentially deadly disease will have a moral duty to quarantine themselves; making what the authorities do merely the enforcement of what a person ought to do anyway.<br></p><p>They use the example of <a href="https://bigthink.com/scotty-hendricks/seven-thought-experiments-thatll-make-you-question-everything" target="_blank">Peter Singer's drowning child</a>. Singer famously asked if we had a moral obligation to save a drowning child if the act of saving them was at a low cost to us. He concluded that we do, and many people agree with him. The authors call this the duty of "easy rescue" and argue that it applies in many quarantine cases since the cost of a person hiding in their room until they know they won't make others sick is typically low while the payoff could include saving lives.</p><p>The authors then suggest that, "when the cost to us of engaging in some activity is small, and the harm to others which is prevented is great, the state may permissibly compel us to engage in that activity." They place this inside of certain parameters, however. </p><p>Most of us would agree that we must keep other people from getting sick when we are ill. However, the suggestion here is that in severe cases, like when the illness in question is deadly, that the state has legitimate power to make sure we stay home. This is more limited than just comparing costs and benefits and doing whatever gives the best payoff, but still allows for interventions during the worst outbreaks.</p>
But what about the freedom of the individual?<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="854435b868180f092dbd4a553a2b5408"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/gKYmVIUwEAw?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>The authors don't suggest that the authorities should always start with quarantines and use them whenever the mood strikes. They make it clear at the beginning of their paper that, "we will argue that authorities ought to implement quarantine and coercion in such a manner that they have the strongest justification possible for those measures.<em>"</em><br></p><p>They also point out that any rational use of quarantines would be limited to severe cases. As they note, while it might be a social net-positive to quarantine people with the stomach flu, the lack of threat it poses makes the action unthinkable. Ebola, on the other hand, is enough of a threat to people that quarantines would be justified. </p><p>At some point though, the freedom of a person to do what they like would be infringed on for the sake of the public health. Many people are put off by this. The question is determining when an individual poses enough of a threat to the people around them that forcing them into quarantine is justified. The authors are of the mind that this is permissible when a person might have a very deadly disease. </p><p>In some cases, quarantine laws are overused and not based on a cost-benefit analysis, such as when New Jersey introduced a quarantine of people who had been in certain African countries during the 2014 Ebola outbreak. The poorly thought out law was changed after a lawsuit was <a href="https://www.nytimes.com/2017/07/27/nyregion/new-jersey-accepts-rights-for-people-in-quarantine-to-end-ebola-suit.html" target="_blank">brought against the state</a>. This case should be a warning against over-application of quarantines, but not against their use when they are correctly implemented. </p><p>The idea of using force to lock people in their rooms to assure that others don't get sick is a tricky one. It makes perfect sense when we're healthy, but seems like a potential use of excessive force when we might be on the sick bed. Nevertheless, the ethics surrounding this issue are far from settled though. Given that we're already preparing for the <a href="https://www.scientificamerican.com/custom-media/jnj-champions-of-science/preparing-for-the-next-pandemic/" target="_blank">next pandemic</a>, we may be ruminating more moral questions sooner than we think.</p>
Researchers found what all viruses have in common and created a therapy that should work on any kind, and will outsmart viral mutation.
If you lined up everything alive on the planet today and counted them one-by-one, you’d find that viruses are the most common creatures by far. Pervasive, pathogenic varieties are notoriously hard to treat, as the recent Ebola outbreak and the Zika pandemic attest. Why is that? Well first off, they are incredibly small, a hundred times smaller than your average human cell. Though they cannot take the immune system head on, they can infiltrate your body, hijack cells and use them to replicate.
Danger is at hand, and you may have voted for it. Science educator Bill Nye weaves a passionate argument for the importance of science literacy in a country's elected leaders.
It’s not unusual to hear someone openly say that they can’t do math at all; that they can’t figure out the percentage to tip on a bill. If someone said that chemistry hurts their brain and they can’t even look at an equation, or that they have no idea how a certain part of the human body does what it does, that wouldn’t be too surprising. These are usually light-hearted statements that go down well – many of us would sympathize, nod and say: yeah, me too.
