What Makes Coronavirus So Infectious? – Cheddar Explains

by birtanpublished on August 29, 2020

Just how infectious is the coronavirus well epidemiologists use something called the reproductive number or are not to gauge how a disease spreads this number describes how many additional people every infected person is likely to pass the virus to before they recover

The common seasonal flu for example has a reproductive number of about 1.3 this means that every person who gets the flu will likely pass it on to you about one or two other people scientists are still working to establish exactly what the

Coronaviruses reproductive rate is but estimates place it between 2 and 3 meaning on average the virus will pass on to 2 to 3 people to get an idea of how huge it difference this is on a larger scale let's do some math first

Let's assume we are only looking at the are not let's also assume we are in a perfect lab setting where no social distancing vaccines or anything like that can slow the virus down in this setting with an R nought of 1.3 like the

Flu one theoretical infected person could lead to about 17 total infections after six rounds of transmissions but with an R nought of 2 to 3 one theoretical infected person could lead to about 100 to 1000 total infections

After just six rounds of transmission either way that's a lot more than 17 and herein lies the potentially daunting scale of the corona virus pandemic one of the reasons that this coronavirus

Goga 19 disease seems to be so contagious is that even though it's spread in a very similar manner to how the flu or influenza is spread no one has any immunity to it whatsoever seasonal flus have to battle

Vaccinations and a portion of the population that has already had that particular virus and developed natural immunity even with experts watching out for potential pandemics virus outbreaks still tend to catch the world off-guard

Somebody has to put the pieces together to know that it's even around and by the time they do the damage all the time an outbreak of this size and scope is also unprecedented we've had other coronaviruses right stars and worse as

Emerging pathogens that never spread like this and then what happened here is it affected so many countries all at once and the supply chain especially because much of it originates in manufacturing plants in China could not

Handle supplying the healthcare systems of all these different countries at once and so what no one ever expected to really have it happened health care systems are becoming overwhelmed simultaneously and there is not enough

Equipment to go around in just the past decade our world has become far more interconnected than it was during the last major pandemic scare SARS SARS first emerged in 2003 since then air travel has more than doubled and a

Lot of that growth occurred in Asia more specifically China this meant that when the coronavirus emerged it likely had a far easier time spreading around the world new research also suggests that the

Virus has a unique structural feature that makes it far more effective at invading your cells then SARS ever was the way this virus and many others invade your cells is through their proteins your cells have their own

Proteins on the outside of that act like locks when another protein comes along that can bind with a protein on your cell your cells sort of opens its doors and lets whatever is attached to that protein in this new study says that

Coronaviruses proteins can bind with your cells 10 times more effectively than SARS can once you become infected though you might not immediately realize that you've contracted the virus it sort of seems like it has just the right

Characteristics to propagate really well people tend to have milder symptoms for about a week and week which gives them a lot of time to be not sick in bed and walking around and interacting at people it's ready the disease Koba 19 has an

Incubation period of up to two weeks this means that you can be carrying the disease and be contagious for days before you show symptoms and some people never show symptoms at all the flu on the other hand has a one to four day

Incubation period and pre-symptomatic spreading is not considered to be a major source of transmission even SARS with about a 2 to 7 day incubation period usually presents much sooner when Utah Jazz player Rudy Gobert became

The first NBA player to test positive for corona virus eight teams test their players of the 13 additional players who tested positive 7 reported no symptoms and remember that Diamond Princess cruise ship that became a floating

Coronavirus quarantine nightmare when passengers couldn't disembark but the virus kept spreading just over half of the 634 passengers who tested positive for Cova 19 reportedly didn't experience symptoms in a preliminary study

Published in the journal science that still needs to be peer-reviewed a group of researchers from top universities including the Imperial College of London Columbia and UC Davis have tried to get a better macro view of this phenomenon

They found that 86% of infections before January 23rd 2020 in China were undocumented and that these undetected infections constitute a large portion of the total force of infection experts caution more research is needed though

Because pre symptomatic and asymptomatic spreaders tend to not drive transmissions with other viruses these unknowns draw attention to another potential reason the virus is spread so rapidly testing issues the United States

Stumbled on the first round of coronavirus test kits leading authorities unable to ramp up testing as the virus took hold this led to an overall fuzzier picture on how the virus was spreading through the population

With ample testing our response to the virus could be more surgical better isolating those who are carrying the virus but don't know it and getting people back to work faster who are healthy all of this info just serves to

Show how crucial social distancing is yes it's a blunt instrument but it's one that can mitigate many of the likely reasons for the spread of kovat 19 as we continue working through this pandemic and of course first and foremost make
