Top 3 coronavirus myths busted

Top 3 coronavirus myths busted

It’s impossible to read about the COVID-19 coronavirus without running into a few dangerous myths.
But some of these myths can be deadly. So let’s explore three COVID-19 myths to learn about the most widely spread rumors.

Myth: Asymptomatic people can’t spread the coronavirus

The idea of the “silent spread” of COVID-19 – that asymptomatic people can spread the coronavirus – has spread like wildfire. 
After some confusion, the World Health Organization (WHO) clarified that most documented cases of “asymptomatic” spread actually turned out to be cases in which the person was presymptomatic and later developed mild or severe symptoms. Therefore, the WHO acknowledged that asymptomatic people can play a role in spreading COVID-19.1  
It’s also important to acknowledge that the term “asymptomatic” as used in everyday conversations can actually have three different scientific meanings:
  • When you’re asymptomatic, you are carrying the virus but show no symptoms. However, you are still able to infect others. 
  • When you’re presymptomatic, you have recently contracted the virus and have yet to show symptoms and are also asymptomatic. You are still able to infect others at this stage of infection and will begin to show mild or severe symptoms.
  • When you are mildly symptomatic, you do not experience pneumonia associated with COVID-19, but rather mild coronavirus symptoms. You belong to the most infectious types of spreaders, as it is highly likely that you’re out and about.
And several extensive studies suggest that cases of asymptomatic people that test positive for COVID-19 often turn out to be presymptomatic.2,3,4 However, all of these “asymptomatic” types of spreaders should be taken seriously. 
According to the WHO, there are three primary ways that you can catch COVID-19:
  1. being coughed or sneezed on by someone with an active infection and symptoms5
  2. touching a surface that carries infected respiratory droplets and then touching your face (eyes, nose, or mouth)6,7
  3. being in enclosed spaces where infected airborne particles can build up
You can transmit the virus with only one mild cough or sneeze containing infected droplets. It’s easy to forget about such a mild symptom and think you never had symptoms at all. But one cough or sneeze is enough to infect others.
Research also suggests that, in confined spaces over prolonged periods of time, COVID-19 can be spread when you sing, yell, or even talk because infected droplets and aerosols from your mouth can hang in the air indefinitely, exposing people nearby to infection even when you’re asymptomatic, presymptomatic or mildly symptomatic.8
But you don’t have to get into the semantics of deciding if someone is asymptomatic, presymptomatic, or mildly symptomatic, as our obsession with semantics could have a deadly impact.
And that’s why it’s so essential to follow prevention protocols, which can reduce your risk of contracting COVID-19 to nearly zero: 
  • Maintain six feet of social distance at all times.
  • Wear a protective face covering.
  • Wash your hands for 20 seconds throughout the day.
  • Don’t share any utensils. 
Following these easy steps will help keep us safe.

Myth: Pets can’t spread the coronavirus

The short explanation is that pet dogs and cats could get COVID-19 from humans and carry and spread the virus to other humans and animals.
It’s worth noting that animals are thought to be the sources of all coronaviruses. 
Although it is rare, scientists suspect the source of COVID-19 was a coronavirus that spread from an animal to a human at a wet market. This was the case with both SARS and MERS. In fact, scientists hypothesize that bats and pangolins are the likely source of COVID-19.10
There’s not a lot of research showing exactly how your pets respond to when exposed to the coronavirus. But we do know that animals can get it from humans and spread it.11 Regarding COVID-19, it’s important to treat a pet like any other member of your family and take precautions to stop COVID-19 to flatten the curve.12
For example, if you have a COVID-19 infection, you can potentially infect your dog with the virus by coughing or sneezing on them. Then, your infected dog, while sitting on your father’s lap, can then cough or sneeze, thus infecting your father by spreading the virus through mucous membranes. 
So to be on the safe side, pet owners should socially distance their pets too. Don’t let strangers touch your pets while you’re outdoors. Infectious droplets could get into your pet’s mucous membranes or reach their face or paws from other pets. 
And if you see someone else’s dog or cat, don’t pet them. 
Cats may be especially problematic when it comes to COVID-19, since cats have a protein receptor called ACE2 that’s very similar to one in humans that the coronavirus latches onto.13
This means that cats might be as likely as humans to become infected with COVID-19 from infected respiratory droplets or transmission through the eyes, nose, and mouth. 
So here’s what you should do to protect your pets and your household:
  • Keep your pets away from infected family members and from other people or their animals outside your home.
  • Don’t let your cats or dogs wander outside beyond your home.
  • Put dogs on a leash at all times outside the house, keeping them 6 feet away from people and animals.
  • Don’t take your pets to places where large groups gather, such as dog parks or indoor pet playgrounds.

Myth: All masks provide equal protection from the coronavirus

Different masks provide different levels of protection from COVID-19. 
Most localities and public health organizations have recommended wearing a simple cloth face covering in public. This will help protect you from large, infectious respiratory droplets.14,15,16,17,18 
But face coverings like cloth masks, bandanas, or gaiters provide limited protection from airborne aerosols in crowded places when social distancing is impossible.19,20,21,22 
Although cloth masks offer limited protection to the wearer, cloths masks are an effective strategy as a collective public effort – as long as everyone wears them. The fewer people that wear them, the less likely it is that this collective public effort will be effective.
There are higher quality masks that offer the wearer a higher level of protection. A certified N95, FFP2, or KN95 respirator maskis designed to protect the wearer.23 These are the only types of masks that provide high levels of personal protection from COVID-19. 
In hospital settings, airborne aerosols that contain the coronavirus can build up to high concentrations in spaces where patients are in close quarters with medical staff.24
Worn properly, medical-grade respirator masks filter out most infectious aerosols and ensure that the air that the wearer breathes is virtually free of aerosolized viruses.25 
Considering the higher effectiveness of N95, FFP2 or KN95 masks, it also makes sense that individuals, especially those who are at higher risk for severe illness, also benefit from higher-level personal protection.

Study Supports Possibility of Vertical Transmission of SARS-CoV-2

Study Supports Possibility of Vertical Transmission of SARS-CoV-2
By Alex Morrison

WEST PALM BEACH, Fla -- July 16, 2020 -- A study presented at the Virtual 23rd International AIDS Conference strongly supports that vertical transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is possible.

Claudio Fenizia, MD, University of Milan, Milan, Italy, and colleagues collected numerous specimens from 31 pregnant women who tested positive for SARS-CoV-2 between March and April, 2020, at 3 hospitals in Northern Italy. Testing for SARS-CoV-2 was done on the mother, the newborn, the placenta, umbilical cord biopsies, maternal and umbilical cord blood, vaginal swabs, breastmilk, and amniotic fluid.

Of the newborns, only 2 tested positive for SARS-CoV-2. In both cases, placenta specimens were also positive for SARS-CoV-2.

“The 2 babies were found to be positive through nasal swabs taken immediately upon delivery,” said Dr. Fenizia. “One of the babies had IgM in the umbilical cord blood. Keep in mind that IgM are not usually transferred in the blood from the mother to the child, so the appearance of IgM is due to direct exposure of the fetus to the virus.”

“We tested all of these specimens looking for the presence of the virus, and our results strongly suggest and support that vertical transmission in 2 cases,” he said.

The researchers also examined the inflammatory processes in the mothers and the children, covering different gestational ages. They analysed the placenta and umbilical cord blood looking for expression and release of inflammatory molecules.

“Indeed, we found quite strong enhanced inflammatory status in infected women compared with negative controls,” said Dr. Fenizia. “This is not really a surprise, but the placenta was extremely inflamed and fetal blood showed higher expression of inflammatory molecules -- this could be more detrimental than even the infection itself during the pregnancy.”

Dr. Fenizia said that both babies who tested positive for the virus are doing well. One continued to test positive for 1 week after birth; the other appeared to just have a transient infection that was not seen in subsequent tests. He said that since the babies were infected within 2 weeks of delivery, he would not expect that their infection would have a long-lasting impact on their development.

“So far, we are not aware of any consequences of infection in these 2 babies, but it is just 2 cases so it is too early to determine any long-term risk for putative infected babies,” he said.

“Our study shows that vertical transmission from mother to child is indeed possible,” said Dr. Fenizia, MD. “This should be considered a preliminary study, and this is basically a picture of women in Italy at the beginning of the infection. There is a question mark as to what will happen if women get infected earlier on in their pregnancy. Further studies should be performed on a wider sample of pregnant women.”

CV IS airborne after all !?

Dear all,

the cowardly and useless organization that President Trump stopped funding a couple of days ago (WHO), has finally admitted today that the CV "might" be airborne.

I have suspected it to be the case in late January, so please be aware that it stays in the air much longer, and much further from  the source of infection that was previously thought.

Hence, stay as far away as you can from every person that is not part of your household, wear proper masks, gloves, goggles and wash your hands as often as you can.

This is not a medical advise, it is just my personal opinion.

Be well,

DrD
