Covid spread смотреть последние обновления за сегодня на .
The COVID-19 virus spreads mainly between people in close contact with each other. It spreads most easily in crowded settings, closed spaces with poor ventilation or through prolonged contact with an infected person. Learn more on: 🤍
COVID-19 spreads when an infected person breathes out droplets and very small particles that contain the virus. These droplets and particles can be breathed in by other people or land on their eyes, noses, or mouth. In some circumstances, they may contaminate surfaces they touch. People who are closer than 6 feet from the infected person are most likely to get infected. COVID-19 is spread in three main ways: -Breathing in air when close to an infected person who is exhaling small droplets and particles that contain the virus. -Having these small droplets and particles that contain virus land on the eyes, nose, or mouth, especially through splashes and sprays like a cough or sneeze. -Touching eyes, nose, or mouth with hands that have the virus on them. Viruses are constantly changing, including the virus that causes COVID-19. These changes occur over time and can lead to the emergence of variants that may have new characteristics. Vaccines continue to reduce a person's risk of contracting the virus that cause COVID-19. Vaccines are highly effective against severe illness. Anyone infected with COVID-19 can spread it, even if they do NOT have symptoms.

High-resolution animation of the global spread of reported infections with the coronavirus SARS-CoV-2, causing COVID-19. The displayed period ends on 25 April 2022, at which date the COVID-19 pandemic had infected over half a billion people and tragically claimed millions of lives. The brighter a pixel, the higher the number of momentarily infected people per unit surface area. Colour is used to distinguish between different virus variants. More precisely, this animation uses a hue-saturation-lightness (HSL) colour model, where the lightness increases monotonically with the reported local counts of currently infected people per unit surface area. A non-linear, approximately logarithmic mapping allows for a high dynamic range of densities to be displayed simultaneously. Different virus variants of “concern”, as defined by the World Health Organisation (WHO), are distinguished by hue: orange for the Alpha variant, yellow for Beta, green for Gamma, blue for Delta, and purple for Omicron. The original “wild-type” variant, as well as less significant mutations are collectively shown in red. The video relies on publicly available data in 370 distinct political regions, which include states/provinces for the USA, Brazil, China, Canada, and Australia. The most important input datasets are daily COVID reports provided by the WHO, complementary data from the Johns Hopkins University Center for Systems Science and Engineering (JHU CSSE), and local estimates of COVID variants based on genetic sequencing, made available by Emma Hodcroft at 🤍. These regional data are combined with a high-resolution (2.5-by-2.5 arcminutes) population density map (2020) published by the NASA Socioeconomic Data and Applications Center (SEDAC). Statistical methods were applied to complete missing and unreliable data points, regions and time periods in these datasets. The virus count on the top right is an order-of-magnitude estimate of the total number of viruses copied since the start of the pandemic, consistent with research results by Ron Sender et al. 2021 (🤍 Further credits: Virus animation: adopted from a protein model by Alexey Solodovnikov published at “N+1”.

Three years into the pandemic and yet another new variant of the coronavirus has emerged. The omicron subvariant known as XBB.1.5 now accounts for more than 40% of new COVID infections in the U.S. and around 75% of cases in the Northeast. Dr. Jay Varma of the Cornell Center for Pandemic Prevention and Response joined William Brangham to discuss the concerns.

Subscribe to The Washington Post on YouTube: 🤍 As winter approaches, the United States is grappling with a jaw-dropping surge in the number of novel coronavirus infections. More than 288,000 Americans have been killed by a virus that public health officials now say can be spread through airborne transmission. The virus spreads most commonly through close contact, scientists say. But under certain conditions, people farther than six feet apart can become infected by exposure to tiny droplets and particles exhaled by an infected person, the Centers for Disease Control and Prevention said in October. Those droplets and particles can linger in the air for minutes to hours. To visually illustrate the risk of airborne transmission in real time, The Washington Post used a military-grade infrared camera capable of detecting exhaled breath. Numerous experts — epidemiologists, virologists and engineers — supported the notion of using exhalation as a conservative proxy to show potential transmission risk in various settings. The highly sensitive camera system detects variations in infrared radiation that are not visible to the naked eye. The technology is more typically used in military and industrial settings, such as detecting methane gas leaks in pipelines. In 2013, it was deployed by law enforcement during the 20-hour manhunt for the Boston Marathon bombers. But fitted with a filter that specifically targets the infrared signature of carbon dioxide, the camera can be used to map in real time the partial path of the nearly invisible particles we exhale.

The primary way of person-to-person corona virus transmission is via aerosols or small droplets created by breathing, sneezing or coughing. The reach of exhaled air can be effectively reduced using a face mask as shown in the video. A simple Schlieren imaging technique is applied to visualize the air flow caused by a person breathing and coughing. Using a face mask the exhaled air flow is blocked reducing effectively the risk of infection. Also nicely shown is the heat transfer from the body to the cooler ambient air. More information about the Schlieren imaging technique is given here: 🤍

Produced by Global Health Media Project in collaboration with Yoni Goodman. Download link: 🤍 Content review provided by experts from CDC, IFRC and UNICEF. The full version of this animation includes Part 1 (transmission and protection) with the addition of a second part on staying safe while caring for a sick person at home. The film starts by following two people who go to a market and shows how they spread the virus to others. Eventually, their whole neighborhood gets infected. The film then explains ways we can protect ourselves and those around us. The story continues as a woman gets sick with the virus. Her family stays home so they don’t infect others, and learn the rules that they need to follow to stay safe while caring for her. The film makes the invisible coronavirus visible, and helps people grasp transmission in a simple and visual way. Through our experience with our animated films on cholera and Ebola, we learned that the image of the visible germ stays with people, helping them make the necessary behavior changes to protect themselves and others and prevent the disease from spreading. This film is intended to help meet the need for better education and awareness that is critical in slowing the spread of this disease worldwide. Director & Animator: Yoni Goodman Producer & Story: Deborah Van Dyke Associate producers: Peter Cardellichio, Mark Binder English narration: Ayesha Casely-Hayford Recording Technician: Tashomi Balfour Music, Sound FX and Mix: Uri Kalian, Sweetsound This animation was produced with support from TEPHINET (Training Programs in Epidemiology and Public Health Interventions Network), LDSC (Latter-day Saint Charities), IFRC (International Federation of Red Cross and Red Crescent Societies), and our individual and family donors from the Mad River Valley, Vermont, and beyond.

Some simple math shows why colleges, businesses, sports leagues and local governments are taking drastic measures — closing schools, canceling games and postponing parades — to combat the coronavirus in the United States. The numbers also show why everyone needs to make the sacrifices necessary to stop its spread, says statistics expert Jorge Luis Romeu, Ph.D. In the above video, Romeu, of Syracuse, explains how just one person diagnosed with COVID-19 on a single day could multiply to more than 30,000 infections per day in just two weeks. In real life, that number would likely be much higher. The short history of this virus shows that one ill person can infect many others. For most people, COVID-19 is no worse than a bad cold or mild flu. But between 10% and 20% of patients are sick enough to require hospital care. That is where the real danger lies, Romeu says. If the coronavirus spreads unchecked, the number of infections grows incredibly fast.
Transmission of SARS-CoV-2 occurs via droplet transmission, contact transmission, and aerosol transmission. Droplet transmission occurs when respiratory droplets produced when an infected person coughs or sneezes are inhaled by a person nearby. Contact transmission occurs when a person touches a contaminated surface and then their mouth, nose, or eyes. Aerosol transmission occurs when respiratory droplets containing the virus mix into the air and then are inhaled. COVID-19 is stable for up to 24 hours on cardboard, 2-3 days on plastic and stainless steel and up to three hours in aerosols, which include fog, mist, dust, air pollutants, and smoke. Therefore, it is possible to get infected by touching contaminated objects or through the air. The incubation period is the time between infection and symptom onset for an illness. Estimates for COVID-19’s incubation period vary from 2-14 days, but it is generally assumed to be around 5 days. There is more debate about the latent period, which is the time between infection and infectiousness. It is now thought that people can be infectious before showing symptoms, and so the latent period is shorter than the incubation period. An imported case occurs when a traveler is infected in one area and is reported as sick in another area. Local transmission occurs if that traveler infects others, or if there is a cluster of cases locally and the spread is easily traced. Community transmission occurs when there is no clear source of infection. Infectivity can be measured using R0. R0 is important epidemiology jargon, short for reproduction number. It is the number of cases, on average, that an infected person will cause during their infectious period. So if R0 =2, then an infected person will infect an average of 2 other people while they are infectious. There are two important variants of the R0. The basic reproduction number represents the maximum potential of a pathogen to infect people – basically what would happen if an infectious person entered a community with no prior immunity. The effective reproductive number describes the current vulnerability of a population based on whether people have immunity thanks to vaccination or prior exposure. The effective R0 decreases over the course of the outbreak. Note that both basic and effective reproduction number depend on factors such as environment and demographics in addition to the pathogen’s infectiousness. The goal of public health interventions is to bring R0 down to less than 1, as this would cause the disease to die out over time. The seasonal flu has an R0 ranging from 0.9 – 2.1. There is a lot of debate about the R0 of COVID-19, with estimates from more recent data ranging from 2.7-4.2. The variance in these estimates is largely due to differing model assumptions and a lack of data. For example, models which assume the possibility of being infectious before symptom onset have estimates that are around 0.5 higher. These high R0 estimates mean there is much greater potential for spread of COVID-19 than for the flu. How much greater? For the purpose of this example, let’s say that the flu has an R0 of 1.5 and COVID-19 has an R0 of 3. After three cycles of infection, 11 people have had the flu, and 40 people have been infected with COVID-19. After ten cycles of infection, this becomes 171 people with the flu, and over 88,000 people with COVID-19. 3D Models from: 🤍 🤍
