Corona virus infections have spiked in recent times and the country is in another shutdown.
However, as winter approaches, many people can mistake what is the real difference between Covid-19 and the flu.
We all constantly hear about coronavirus and how lethal it is – but what really makes it different and what about stupid people claiming “it’s not worse than the flu”?
Dr. Justin Varney, Birmingham’s director of public health, told BirminghamLive the difference. Speaking on a special Facebook Live broadcast, he said: “It’s definitely not the flu. It’s a different kind of creature.
“If you look at it under a microscope, it looks completely different.
“But it goes the other way too. Influenza is a respiratory illness and mainly, people get very sick because when you get a bad flu, you have difficulty breathing and possibly have lung fluid, and we call it that.”; pneumonia.
“Coronavirus does that but it does other things as well. It seems to disrupt people’s blood clotting, so they end up with blood clots.
“It also gives people a high fever, and the flu doesn’t have to be that way.”
Here are four ways Covid-19 differs from seasonal flu, with some help from Mirror.
Scientists have yet to see any human immunity to Covid-19
We do not yet have a vaccine for Covid-19, while each year the NHS offers a new influenza vaccine against the latest seasonal strain of the virus.
Covid is more contagious than seasonal flu – and our lack of immunity is a key factor, scientists say.
Airborne virus specialist Professor Linsey Marr, who teaches civil and environmental engineering at Virginia Tech University in the US, warns the lack of Covid-19 immunity in the population leads to the so-called is the ‘super spread’ event.
Professor Marr explained to the Huffington Post that more people in any given room are more likely to be infected with coronavirus than to get the flu and this is not due to the nature of the virus but the lack of immunity in the population.
So, as we all know, the race to find a vaccine for Covid-19 is or is of vital importance if we want to fight this virus now – and for years to come, like we do with seasonal flu.
Some people carrying Covid-19 ‘have no symptoms’ and do not have any symptoms
Covid-19 and the flu share a number of symptoms, including a high temperature and a cough.
You can both see that you have a dry cough and with Covid the cough will persist.
While people with the flu often have headache and loss of appetite.
But scientists soon discovered during the pandemic that some people can acquire and carry Covid-19 without showing any symptoms.
And this is another reason why coronavirus spreads more widely and faster than seasonal flu.
If someone does not know they have the virus – because there are no signs of any symptoms – then they will not isolate themselves or stay away from everyone, meaning they will accidentally spread it.
Some scientists have even suggested that between 40% and 50% of people with Covid-19 have no symptoms.
There are some cases of flu where people have no symptoms, but one key difference is that Covid-19’s ‘incubation period’ is longer.
Professor Marr explains the incubation period – the period from exposure to the virus to symptoms or not – is up to 14 days with Covid, while people with the flu tend to have the following symptoms. three days.
This means that the chances of spreading the flu to others and / or accidentally doing so are much shorter.
Flu ‘viral load’ – the amount of virus in the body fluids – does not tend to start until symptoms are seen.
But with Covid-19, this could take up to two weeks.
Virus transmission is higher
Professor Marr outlined how a person with the seasonal flu would on average infect 1.3 others.
But with coronavirus, the spread of this virus is almost double – 2.5 people.
An example of the hyper-contagious event is at the White House Rose Garden, when the leading US scientist, Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, revealed at least 11 people. got this bug.
Donald Trump’s team is notorious for forgetting to wear masks during a pandemic and at a White House event in September we saw how Covid-19 could be spread to more than 10 people at an event.
Dr. Fauci said at the time: “We had a super viral event in the White House, and it was a situation where people were squeezing together and not wearing masks.”
And Professor Marr supports this, emphasizing how successfully away from society and properly using the veil make it difficult for Covid to spread at a rate of 2.5.
Covid transmission is different in children compared to adults
Leading researchers at King’s College London in the UK found that children had different Covid symptoms compared to adults, backing up other studies showing that viral transmission is different in children and Adults.
And the World Health Organization has previously said “children are the key driver of the spread of influenza viruses in the community.”
It added: “For the Covid-19 virus, initial data indicated that children were less affected than adults and that the rate of clinical attack in the 0-19 year old group was low.
“Further preliminary data from Chinese household transmission studies show that children are infected from adults, rather than the opposite.”
The WHO also reminds that, when it comes to seasonal flu, children are known to be at greater risk for serious infections.
Children younger than 6 months of age are most at risk of serious complications from the flu because their immune systems are less developed and fragile, and in fact they are too young to receive a flu shot.
Pregnant women, the elderly and people with pre-existing health conditions are also at greater risk of catching the flu – just as with Covid.
But for children at least, with coronavirus, it seems children are okay, as the main risk occurs in the elderly and people with a pre-existing health condition.
“For Covid-19, our current understanding is that older age and underlying conditions increase the risk of serious infections,” the WHO added.
