The Math Behind Social Distancing As we wait for scientists and healthcare professionals to develop a vaccine for COVID-19, there is another, more readily available tool at our disposal. Social distancing, defined as measures taken to reduce physical contact, is the first line of defense for containing an infectious disease like COVID-19. That’s because these infections spread when people cough, sneeze, or touch surfaces on which the virus resides. To help us grasp the impact these measures can actually have, today’s infographic illustrates how a reduction in social exposure can theoretically contain the spread of infection. Theoretical Potential The calculations used to create today’s infographic come from Signer Laboratory, a stem cell research lab located in the Moores Cancer Center at the University of California San Diego. Using a summation formula makes it possible to estimate the number of new infections over a 30 day period, across three scenarios. Scenario 5 Day Period 30 Day Period No social distancing practiced 1 person infects 2.5* others 406 people infected as a result 50% reduction in social exposure 1 person infects 1.25* others 15 people infected as a result 75% reduction in social exposure 1 person infects 0.625* others 2.5 people infected as a result *For estimations only. It is not possible to infect only a fraction of another person. To arrive at the figures reported above, Robert A.J. Signer, Ph.D., and his team made a number of key assumptions. First, they estimated the basic reproduction number (R0) of COVID-19 to be 2.5, a figure supported by recent research. This means that, on average, an infected individual will spread the disease to 2.5 other people. Next, they assumed that an infected individual will unknowingly spread COVID-19 over the median five day incubation period. After this period, the individual will begin to develop symptoms, immediately self quarantine, and no longer pose a threat. Finally, they assumed a direct linear correlation between social interactions and R0. This means that when an infected person reduces their physical contact with others by 50%, they also spread the disease by an amount 50% less. https://www.visualcapitalist.com/the-math-behind-social-distancing/ Lots more great info in article.

Agree with this Fox. Face everything and Rise going to do.

I know what you mean. It's picking up in small rural town I live in NY. Was only 12 cases couple days ago now up to 28 for the county.

Agree with this post

Kissinger every time I see what he says or hears just makes me puke. A globalist. Don't really like him at all.

To me still pretty high numbers (right now with heat). Without the heat would hate to see how badly gets there.

Wow just amazing

Hello everyone, and I had the opportunity to visit Cassandra at Buffalo Children's today. As mentioned she is off the Ecmo machine and doing most of the work. It will take some time for her to heal. She gets better every day. Prayers and time will help her heal. We don't know yet what virus did this. It was not covid. She was tested a few times for that and all negative. Thank you for all the outreach and we will keep you posted. My best advice to parents is tell your children you love them everyday. You never know what the next day will bring. Easter is a special holiday happening tomorrow. Please cherish and make it the best for your children and yourselves. It will be a hard holiday for us to get through but we will make the best of it. Your outreach has been extremely powerful and it is helping us get through this hard and difficult time so thank you and Happy Easter. Ya looks like not covid. But telling my sister, got to keep her away from this virus. Might agrument with her, she might hate me. After fighting something bad. But glad she is doing better. Worries me if a nurse or doctor infected or dirty clothes (from working someone else) get her infected. This virus is scary after a person struggling thru something else fighting else. Worries me.

This video might be off topic (or on) but soo much information in it. For the ACE 2. And for the heart. Kind of deep info. myocardial on the heart has ACE2 on the heart. Really deep info.

Love seeing these LOL

But ya President Trump is a good leader. Very good President.

Hope soo. Plus I think America should kick out anything China owned. I think they have some control in Hollywood (many lots more). America should build it's own things and only own things. No control from any any country.

Wow that's awful. Feel badly all the people live there have to go thru that crap.

Yeah another thing i'm worried about. Might be a stronger flu or less flu shots. So so on flu shots. Hoping labs prepared in case.. Flu changes every year. Why for vaccines. How Influenza (Flu) Vaccines Are Made Español medical icon Selecting Viruses for the Seasonal Influenza Vaccine lab icon Advancements in Influenza Vaccines On This Page Egg-Based Flu Vaccines Cell-Based Flu Vaccines Recombinant Flu Vaccines For the United States there are three different influenza vaccine production technologies approved by the U.S. Food and Drug Administration (FDA)external icon: egg-based flu vaccine, cell-based flu vaccine, and recombinant flu vaccine. All commercially available flu vaccines in the United States are made by private sector manufacturers. Different manufacturers use different production technologies, but all flu vaccines meet FDA safety and effectiveness requirements. Different vaccines have different indications. See Influenza Vaccines — United States, 2019-2020 Influenza Season for specific indications. Egg-Based Flu Vaccines The most common way that flu vaccines are made is using an egg-based manufacturing process that has been used for more than 70 years. Egg-based vaccine manufacturing is used to make both inactivated (killed) vaccine (usually called the “flu shot”) and live attenuated (weakened) vaccine (usually called the “nasal spray flu vaccine”). The egg-based production process begins with CDC or another laboratory partner in the WHO Global Influenza Surveillance and Response System providing private sector manufacturers with candidate vaccine viruses (CVVs) grown in eggs per current FDA regulatory requirements. These CVVs are then injected into fertilized hen’s eggs and incubated for several days to allow the viruses to replicate. The fluid containing virus is harvested from the eggs. For inactivated influenza vaccines (i.e., flu shots), the vaccine viruses are then inactivated (killed), and the virus antigen is purified. The manufacturing process continues with quality testing, filling and distribution. For the nasal spray flu vaccine (i.e., the live attenuated influenza vaccine – LAIV), the starting CVVs are live, but weakened viruses that go through a different production process. FDA tests and approves all influenza vaccines prior to release and shipment. There are several different manufacturers that use this production technology to make flu vaccines for use in the United States. This production method requires large numbers of chicken eggs to produce vaccine and may take longer than other production methods.

Ya looks like we have ACE 2 receptor in our lungs, heart, intestines, kidneys. And some other places. Just wondering if get covid19 in heart cause of ACE2 (heart failure). Does it count like that or some other failure? https://en.wikipedia.org/wiki/Angiotensin-converting_enzyme_2 Angiotensin converting enzyme 2 (ACE2)[5] is an enzyme attached to the outer surface (cell membranes) of cells in the lungs, arteries, heart, kidney, and intestines.[6][7] ACE2 lowers blood pressure by catalysing the cleavage of angiotensin II (a vasoconstrictor peptide) into angiotensin (1–7) (a vasodilator).[8][9][10] ACE2 also serves as the entry point into cells for some coronaviruses.[5] The human version of the enzyme is often referred to as hACE2.[11] ACE2 counters the activity of the related angiotensin-converting enzyme (ACE) by reducing the amount of angiotensin-II and increasing Ang(1-7)[12] making it a promising drug target for treating cardiovascular diseases.[13][14

Ya kind of does feel like it.

Wow gotta hate people who hurt girls or women. Lots people around here ( I live)like Biden. Took me short time check him out and said no thanks.

Agree DR

Don't know if been posted but this is wonderful from President Trump

That was awful when said happy talk when Acosta asked. Nothing is happy about this coronavirus. For everyone.

Thanks very much buddy.

He said the virus can lead to heart attack or inflammation called myocarditis, and it can stress the heart. He said some patients with cardiovascular issues resulting from the virus have not shown other common symptoms. “What’s been very surprising is that there is a group of patients who actually present with heart symptoms and no fever or cough or respiratory symptoms,” Shishehbor said https://fox8.com/news/coronavirus/local-doctors-say-they-are-seeing-increasing-impact-of-covid-19-on-the-heart/ More info in article. Ya my niece in the hospital usly post in PPP. Was on a ECMO. Off now I guess following my sister facebook. First test was neg but took second test still pending. Myocarditis. She is now 6 age young. Unconscious. But getting better. Everything still a unknown as of right now if covid19 or not.

Cassandra has just been disconnected from the ecmo machine. She is breathing and circulating the oxygen through her body on her own now. She is still going to be unconscious for a few days, but it is getting better. My sister posted again. Just wondering if they do work on to figure what type of virus by blood or something if not covid19. Sorry everyone if I said off ECMO get different things (maybe looks like now possibly for good) Wish I could go see her. My mother not the best shape and my brother as well. Usly have to take by phone or facebook to understand.

CLEVELAND (WJW) – The impact of COVID-19 on the lungs has been well documented, but local doctors say they are seeing increasing impacts of the virus on the heart. Doctors say people with underlying conditions, including heart disease and hypertension are at a higher risk of death. “If you have heart disease, you’re no more likely to get it, but you have a great stake in preventing yourself from getting it,” said Cleveland Clinic heart surgeon Dr. Marc Gillinov. “If your heart is already weakened by heart disease and you get COVID-19 and it affects the heart, that’s a dire situation.” Dr. Mehdi Shishehbor, Director of the University Hospitals Cardiovascular Interventional Center, has treated coronavirus patients and said about one in five experience cardiovascular impacts. “If COVID affects the heart, we really need to be very careful with those patients, and they need to be monitored very carefully because of the risk of death,” Shishehbor said. He said the virus can lead to heart attack or inflammation called myocarditis, and it can stress the heart. Shishehbor said underlying cardiovascular disease increases the risk of death from coronavirus by two to three times, and if patients have markers that the virus has damaged the heart, the risk of death increases by seven to eight times. He said some patients with cardiovascular issues resulting from the virus have not shown other common symptoms. “What’s been very surprising is that there is a group of patients who actually present with heart symptoms and no fever or cough or respiratory symptoms,” Shishehbor said. https://fox8.com/news/coronavirus/local-doctors-say-they-are-seeing-increasing-impact-of-covid-19-on-the-heart/

Always BBF. Always InItTogether. Thanks buddy and everyone.
