As scientists continue to learn more about the COVID-19 epidemic, there has been increased speculation that many people may have already had a coronavirus but did not know it because their symptoms did not affect them massively.
Research by scientists at the University of Oxford’s Evolutionary Ecology of Infectious Disease group has developed a scenario in which millions of Britons may already have caught a coronavirus, reports Coventry Live.
The scenario is just one of the many possibilities presented by the researchers.
In the non-peer-reviewed study, they suggest that the coronavirus, like many emerging infections, may have spread undetected for a month before its effects became apparent in late February.
If the Oxford researchers are right, up to half of the country’s population may already have been infected.
Many people have contacted news publications or social media to report experiencing COVID-19 symptoms in the weeks following the new year.
The College of Optometrists said, “It is recognized that any upper respiratory infection can cause viral conjunctivitis as a secondary complication, and this is also the case with Covid-19.
“However, it is unlikely that a person will have viral conjunctivitis secondary to Covid-19 without other symptoms of fever or a continuous cough because conjunctivitis appears to be a late characteristic where it occurred. “
A cough that sounds “different”
We all know that a persistent dry cough is one of the main symptoms of coronavirus.
But many have started to describe a COVID-19 cough as different from what you can usually have.
The cough is persistent, more difficult to fight and, for smokers, will be different from a usual smoker’s cough.
It is likely to last at least half a day.
Thea Jourdan told the Daily Mail that she first thought she might have been infected when she had a tickle in her throat and headaches.
The mother of three then began to experience brain fog.
“At first I felt exhausted, like I was dragging myself through molasses and that I had no choice but to go to bed. I didn’t have a significant cough and I didn’t have a fever, “said the Hampshire woman.
“But I had a special feeling of something settling deep in my lungs, almost like breathing talcum powder. “
Be warm to the touch
High temperature is considered a fever when it reaches 37.7 ° C (100 ° F).
Although the numbers may vary for different people.
If you feel hot to the touch, especially on your chest or back, you are likely to have this symptom.
Out of breath
If you have a tight chest or trouble breathing, this may be a sign that you have a coronavirus.
Dyspnea – the term for someone who has difficulty breathing – can be associated with chest tightness, rapid breathing, and heart palpation.
However, most young people or those without pre-existing health conditions are unlikely to experience this symptom.
Sudden loss of smell or taste
The British Association of Otorhinolaryngology has warned that losing your sense of smell and taste could mean that you have Covid-19.
The ear, nose and throat specialist recommended that anyone with such symptoms isolate themselves immediately.
It has been suggested that the phenomena could be caused by coronavirus killing cells in the nose and throat.
“Evidence from other countries that the point of entry for the coronavirus is often in the eyes, nose and throat,” the association said in a statement.
“We have also identified a new symptom (loss of smell and taste) which may mean that people without other symptoms but with just the loss of this sense may have to isolate themselves – again to reduce the spread of the virus. “
As with a loss of appetite, enduring a stomach ache can easily be taken as a sign of something more innocuous.
However, a study recently published by the American Journal of Gastroenterology links belly problems to Covid-19.
They found that 48.5% of the 204 people infected with the coronavirus in the Chinese province of Hubei had digestive symptoms such as diarrhea.
Jaimuay Sae-ung, 73, was the first Thai national to contract a coronavirus in December of last year.
Despite underlying health problems, including a heart problem, Jaimuay survived the illness after doctors isolated him in a hospital in Thailand for treatment.
“I didn’t know (I had a coronavirus) until after I got to the hospital,” the mother of seven told Sky News.
“I felt a little sad, a little shocked, tired and tired and I couldn’t eat. “
