  • High speed camera captures how different types of face masks work


    Which mask works best? To visualise droplets and aerosols, UNSW researchers used LED lighting system & a high-speed camera, filming people coughing and sneezing in different scenarios — using no mask, 2 different types of cloth masks, and a surgical mask.

    We confirmed that even speaking generates substantial droplets. Coughing and sneezing (in that order) generate even more.

    A three-ply surgical mask was significantly better than a one-layered cloth mask at reducing droplet emissions caused by speaking, coughing and sneezing, followed by a double-layer cloth face covering.

    A single-layer cloth face covering also reduced the droplet spread caused by speaking, coughing and sneezing but was not as good as a two-layered cloth mask or surgical mask.

    We do not know how this translates to infection risk, which will depend on how many asymptomatic or mildly symptomatic infected people are around. However, it shows a single layer is not as good a barrier as a double layer.

    Here's more on what we found:

  • What Made The Black Death so Deadly?


    In modern times, if you get sick your parents take you to the doctor and you get some medicine to feel better, but in the fourteenth century illnesses like The Black Death would spread from town to town, wiping out entire villages of people. In today's educational animated video we look at what made The Black Death so deadly.
    How terrible was this SICKNESS and ILLNESS? What can we learn from the history about this disease? Is the pandemic truly gone or can it one day come back? In what year did the plague doctors actually appear?

  • What face masks actually do against coronavirus


    Face masks don't make you invincible.

    Support Vox by joining the Video Lab at or making a one-time contribution:

    The fight against coronavirus is global. But the guidelines on whether you should wear a face mask as part of that fight are often completely different from place to place. That means that, for a lot of people, whether you wear a face mask when you leave the house is basically up to you.

    Here’s where almost every expert agrees: If you have Covid-19, and you leave the house, you should wear a mask. Masks help keep sick people from spreading their germs. Most of the uncertainty around mask use is related to a totally separate question: Whether masks can protect healthy people from getting Covid-19.

    The truth is that no mask can actually guarantee that you won’t get sick; experts say one of the most dangerous assumptions about face masks is that they basically make you invincible. Masks have to be used correctly to offer any protection at all, and they’re most effective if used alongside other preventative measures like hand-washing and social distancing.

    But experts also say that the question of whether healthy people should wear masks is a lot easier to answer when you consider one of Covid-19’s most dangerous characteristics: Because of the disease’s long incubation period, and the high occurrence of infected people who never feel symptoms at all, it’s almost impossible to be completely sure that you don’t already have it. And that means the safest course of action is ultimately for everyone to behave like a sick person; in other words, to wear a mask.

  • Can copper kill coronavirus?


    Could copper help us fight disease and slow down their transmission?
    Engineers, we need your help:

    Can Copper Kill Coronavirus?

    Covid-19 has swept through the world, causing an emergency unlike anything experienced in in most of our lifetimes. This pandemic has left experts scratching their head, wondering what could have been done differently to have mitigated this catastrophe.

    But, could the answer be as simple as replacing surfaces with a common metal?

    Since copper is a naturally occurring metal, it has been used by man since the early days of humanity for objects, such as weapons, tools and jewellery. In ancient Egypt, they used it to purify water as well as to sterilise battle wounds to prevent infection. Many societies having been brewing and drinking tea in copper appliances. People in India and turkey have been proclaiming the health benefits of this for centuries.

    These examples are years before our scientific understanding of microbes had developed, but it is clear to see that people have been aware of its health benefits for a long time.

    At the start of the 21st century, Professor Bill Keevil, the Director of Environmental Healthcare Unit at Southampton University, started to really probe what it was about copper that had made people throughout history recognise its healing potential. He found that the copper ions penetrate bacteria cells and inhibit their respiration. He also discovered that the ions attacked the DNA of the cell and destroyed it making gene transfer no longer possible.

    Speaking to Healthcare in Europe he said…“We know that copper kills viruses and destroys DNA, including plasmids, so this should stop the transfer of DNA, which would include those toxic genes and also the transfer of antibody resistance from one species to another”

    So, with the health benefits of copper known, why don’t we see it used more today?

    Well, stainless steel and plastic surfaces are generally considered cleaner looking and so they have become readily adopted in hospitals to help patients feel that they were in sterile surroundings.

    Also, there’s a general misconception that silver is a better antimicrobial metal and while it’s true that silver does have an antibacterial effect, it does not have this effect when the surface is dry, whereas copper works without the need of moisture.

    According to research conducted by the New England Journal of Medicine, COVID-19 lives on copper surfaces for 4 hours while managing to survive on plastic and stainless steel for up to 3 days! However, truth be told, anti-bacterial cleaning and hand washing is still very much needed, but having copper doorknobs and surfaces, especially in hospitals, could help stop or slow down the transmission of germs and diseases.

    Covid-19 has already swept across the globe so it’s too late to change our surfaces now. But sadly, this won’t be the last pandemic, and perhaps the switch to copper can prepare us for the next one

    Our hands are covered in thousands of germs. We may not be able to see them, but they are there.

    You may think that you are killing these germs when you wash your hands. Think again. Most people wash their hands too quickly to kill most germs. And few people dry their hands properly. Wet, partially washed hands make it easy for germs to grow and spread.

  • Infections and deaths after vaccination


    E mail from CDC to CNN, Breakthrough infections

    Vaccinated people who become infected = 5,800

    About 1 in 13,275

    At least 14 days after their final dose

    Asymptomatic, 29%

    Required hospitalization = 396 (1 in 194,444)

    Deaths = 74 (1 in 1,040,540)

    CDC currently investigating factors

    May be more cases to report due to reporting lag

    From 77 million fully vaccinated

    (Fully vaccinated as of today = 80.6 million)

    From trials

    Pfizer/BioNTech, 95% effective in preventing symptomatic disease

    Moderna, 94% effective in preventing symptomatic illness

    Johnson & Johnson, 72% from US data

    Characteristics of breakthroughs so far

    40% of the infections were in people 60 or more

    65%, were female

    CDC is monitoring reported cases for clustering by patient demographics, geographic location, time since vaccination, vaccine type or lot number, and SARS-CoV-2 lineage

    CDC also continues to recommend people who have been fully vaccinated should keep taking precautions in public places, like wearing a mask, staying at least six feet apart from others, avoiding crowds and poorly ventilated spaces, and washing their hands often

    Dr. Carlos del Rio, Emory University School of Medicine

    Less transmission means fewer breakthrough cases

    There is currently a lot of transmission in many parts of the country

    Vaccines will help decrease that

    Get vaccinated as soon as you can and help control this pandemic

    National Institutes of Health Director Dr Francis Collins

    Allow more time for scientists to investigate links between the vaccine and blood clots

    and whether or not certain groups of people are more susceptible

    India, double mutation variant emerge

    Hey john thanks for the update. I am from Delhi, India and I have contracted the virus. Situation in India is very bad. Most of the hospitals are already exhausted and many people are dying without treatment.

    The India variant, B.1.617

    E484Q and L452R

    First reported in India, late 2020

    Aparna Mukherjee, Indian Council of Medical Research

    has not been stamped as a ‘variant of concern’ so as to say that it is more lethal or more infectious


    Very low prevalence in January

    April, 52% of samples sequenced

    Maharashtra state, 60%

    Has been detected in 10 other countries, US, UK (77 cases) Australia and New Zealand

    (L452 from US data, 20% more transmissible, reduces antibody efficacy by more 50%)

    William A. Haseltine, former professor, Harvard Medical School

    The B.1.617 variant has all the hallmarks of a very dangerous virus

    We must do all that is possible to identify its spread and to contain it


    Trying to get more drugs from Spain

    Rio de Janeiro, health-care workers forced to intubate patients without sedatives

    Mechanical restraints and neuromuscular blockers

    Doctors Without Borders

    More than 12 months into Brazil’s covid-19 emergency, there is still no effective, centralized and coordinated public health response to the outbreak

  • Why is pneumonia so dangerous? - Eve Gaus and Vanessa Ruiz


    Explore how pneumonia attacks the tiny air sacs in your lungs and how your immune system works to fight off the infection.


    Every time you breathe, air travels down the trachea, through a series of channels, and then reaches little clusters of air sacs in the lungs. These tiny sacs facilitate a crucial exchange: allowing oxygen from the air we breathe into the bloodstream and clearing out carbon dioxide. Pneumonia wreaks havoc on this exchange system. Eve Gaus and Vanessa Ruiz detail how pneumonia attacks the lungs.

    - paraffin accumulates in the liver, kidneys and lymph glands.
    - vaseline dries the skin of your lips.
    - lanolin disrupts the work of the stomach and intestine.

    - carmine can cause skin irritation or allergies.
    - mica and silica, these produce the glimmering effect, but can cause skin irritation.

    PRESERVATIVES disrupt the work of the internal organs.

    AROMATIZERS can cause strong allergic reactions.

    AROMA AGENTS raise blood pressure and cause migraines.

    Try to use lipstick with more natural ingredients. Instead of lipstick, use lip balm more often. It's colorless, and therefore less harmful.
    Don't ever squeeze blackheads!

    The core won't fully come out. The skin will be damaged and inflamation will occur. Don't squeeze them in the 'danger zone'. This risks the appearance of the infections in the brain.

    Blackheads are easily confused with moles. Don't use tweezers or needles to remove them. You can damage the facial nerve. Plus frequent squeezing of blackheads exhausts the skin's resources. Scars and slashes can be left on the face.

    Try to avoid these harmful habits. Stay safe and sound! ; )

    Bottom line: Masks work. They are safe for almost everyone to wear, and the more people that wear them along with adhering to physical distancing and other strategies, then that's more lives we'll save. But there's still a lot of confusion and misinformation out there when it comes both to wearing masks and the actual risks of getting infected with COVID-19. In this video, I address a few of the most common myths and misunderstandings using scientific evidence. #WearAMask

    00:00 Introduction
    00:46 Myth 1: Farts vs. viral particles
    02:20 Myth 2: Cloth masks can't stop viruses

    Masks reduce the spray of droplets when worn over the nose and mouth

    Prevent people who have COVID-19 from spreading virus to others

    Respiratory virus shedding in exhaled breath and efficacy of face masks (Nature Medicine)

    Aerosol transmission is a potential mode of transmission for coronaviruses as well as influenza viruses and rhinoviruses

    Universal use of face masks for success against COVID-19: evidence and implications for prevention policies (European Respiratory Journal)

    Cloth masks are a simple, economic and sustainable alternative to surgical masks as a means of source control of SARS-CoV-2 in the general community

    Mask wearers are dramatically less likely to get a severe case of Covid-19

    Professor Monica Gandhi, San Francisco General Hospital.

    No mask is perfect

    Wearing one might not prevent you from getting infected

    But it might be the difference between a case of Covid-19 that sends you to the hospital and a case so mild you don’t even realize you’re infected.

    Masks Do More Than Protect Others During COVID-19: Reducing the Inoculum of SARS-CoV-2 to Protect the Wearer (Journal of General Internal Medicine)

    Universal masking reduces the “inoculum”

    Leading to more mild and asymptomatic infection manifestations

    Masks, depending on type, filter out the majority of viral particles, but not all

    Viral inoculum and severity of disease (LD50)

    Rising rates of asymptomatic infection with population-level masking

    Increased with mask wearing, decreased where few masks are worn

    So, more asymptomatic infections

    Greater community-level immunity and slower spread

    Cloth Masks May Prevent Transmission of COVID-19: An Evidence-Based, Risk-Based Approach (Annals of Internal Medicine)

    The point is not that some particles can penetrate but that some particles are stopped

    Every virus-laden particle retained in a mask is not available to hang in the air as an aerosol or fall to a surface to be later picked up by touch.

    Cloth can block droplets and aerosols, and layers add efficiency.

    Immunity and immunopathology to viruses: what decides the outcome? (Nature, Reviews Immunology)

    The outcome of host–viral interactions depend on

    Dose and route of infection

    Viral virulence properties

    Several host factors that mainly involve innate and adaptive immunity

    If the exposure dose is very high, the immune response can become overwhelmed.

    If the initial dose of the virus is small, the immune system is able to contain the virus with less drastic measures.

    If this happens, fewer symptoms, if any

  • How Do Masks Really Help Us?


    In the earlier days of the coronavirus pandemic, there was a lot more confusion about whether people should wear masks to protect themselves and others from the virus. Here’s why recommendations have changed – even for kids and teens – and how they help keep COVID-19 in check.

    SUBSCRIBE so you never miss a video!

    And follow us on Instagram and Twitter!

    **Why did the Centers for Disease Control change its guidance on wearing masks?
    Initially, there were concerns that if the public were instructed to wear masks, there wouldn’t be enough surgical masks or N95 respirators for health care workers. There’s also a clearer understanding of how the coronavirus spreads, and that pre-symptomatic and asymptomatic transmission is possible. That’s when you might be contagious but don’t know it – and might unknowingly infect someone else. So wearing a mask helps cut down the risk for everyone.

    **If we’re social distancing, do we still need to wear masks?**
    Yes – respiratory droplets carrying the virus can travel much further than 6 feet, and since we don’t always maintain 6 or more feet of distance -- it’s better to take this precaution, along with washing your hands and watching your distance when possible.

    **Does the type of mask you wear matter?**
    While some masks are more effective than others, some experts suggest that the best mask is one that’s both comfortable and that you’ll wear consistently. Any mask that covers your nose and mouth will have some benefit, although N95 masks with valves won’t protect others around you.

  • Smallpox to COVID: a comparison of vaccine development


    Join us to explore the historical and modern-day development of vaccination comparing the first and only human disease eradicated by vaccination, smallpox, and today’s global challenge, COVID-19. This event was recorded live on 15 July 2021.

    Learn about ‘A Pox In All Our Houses: Discovering the origin and evolution of smallpox vaccine’ the fascinating ongoing research project with Dr Ana Duggan, adjunct assistant professor at McMaster University, and Anna Dhody, curator of the Mütter Museum. Using the latest scientific techniques, this project is sampling historic items associated with smallpox vaccination to answer questions about the variety of viruses used for vaccination purposes across the globe during the 18th and 19th centuries. One of the items sampled is a set of blades from the RCP collection that is likely to have belonged to Edward Jenner (1749–1823), the doctor who greatly advanced the development of smallpox inoculation.

    In comparison we will also hear from Dr Gregory Poland director of the Vaccine Research Group at the Mayo Clinic, about how today's COVID vaccines are being developed to tackle a modern, pandemic disease.

  • Full Webinar | The Science behind the Homemade Mask


    The Science behind the Homemade Mask| with Dr. Anne Bissonnette

    From design, to material, to construction tips, this webinar shares Dr. Anne Bissonnette's research about the science behind the homemade cloth face mask. What appears to be a simple object is actually quite problematic. As a garment made by individuals who are using materials readily found in their surroundings, and in designs that, like the materials, have not been tested for their effectiveness in preventing infection, the face mask varies immensely from maker to maker.

    She discusses history, solid scholarly evidence and shares her informed opinions to answer questions many of us makers have. This webinar includes a demo, where Dr. Bissonnette shares masks in various stages to demonstrate construction.

    About our guest: Dr. Bissonnette is an Associate Professor at the University of Alberta. She teaches Material Culture and Curatorship and is also the Curator of the University’s Anne Lambert Clothing and Textiles Collection. Her areas of research consist of fashion from the late eighteenth century to the present day, with a special interest for the cut and construction of clothing, how bodies and clothes interact, and on the convergence between art, fashion, and science.

  • Lucy Shapiro Part 2: Escalating Infectious Disease Threat


    Many antibiotics, which we have taken for granted since the 1950's, are now becoming ineffective because bacteria have developed ways of acquiring resistance. The development of new antibiotics is lagging behind the loss of the old ones in this race to combat infectious disease. Simultaneously, there is an increase in infectious diseases around the world due to over population, globalization and urbanization. This results in a lethal combination of emerging diseases and loss of effective antibiotics. Multiple factors have contributed to this escalating scenario. The world is now a global village, there is a loss of control of national borders, there are significant populations of aging and immuno-compromised people, there are drastic chnges in global ecology, and migration pathways of animal and insect vectors are changing due to urbanization and global warming. Large networks of epidemiologists and scientists worldwide are now working to coordinate detection, diagnosis and treatment of infectious disease flare-ups in order to contain the threat of epidemics.

    Educational video for children to learn what microorganisms are and what types of microorganisms there are. When were microorganisms discovered? How do we observe them? Did you know that we classify them into three types? Bacteria are prokaryotic cells and have no nucleus. Viruses are not living beings, they are much smaller and some of them cause diseases like flu or chickenpox. Some fungi are microorganisms bigger than bacteria or viruses, they can be found in the air, in plants or in the water. In this video, children will learn how to distinguish between viruses and bacteria. They're both called pathogens and cause diseases that spread very easily through the so called vectors.

  • Dr. Jeremy Faust on a year of the coronavirus: How far weve come and how much weve learned


    On March 11, 2020, the World Health Organization declared the coronavirus a pandemic. And, after watching the slow tidal wave of infections, deaths, and fear consume most of Asia and Europe, Americans finally felt COVID’s impact at home. This totally unknown, novel virus took root, upending our lives. On this week’s episode of Next Question with Katie Couric, we recognize this sobering anniversary of a full year with the pandemic. Three Americans intimately involved with COVID-19 — an ER doctor, an epidemiologist, and a patient — share their experiences in those early, panic-stricken days and months of the spring 2020 to find out just how far we’ve come from and just how much we’ve learned about COVID-19, our healthcare system, science, and maybe even ourselves.

  • How Much Do Cloth Masks Protect You From Getting the Coronavirus?


    The CDC is recommending that the general public wear cloth face masks to help decrease everyone’s chances of getting COVID-19. So how does the virus that causes COVID-19—SARS-CoV-2—spread? And how much could cloth face masks help stop it? We contacted some experts to find out, and to learn what materials work best if you’re making your own.
