It’s now nearly six months for the reason that world turned conscious of COVID-19, and nearly 4 months for the reason that World Well being Organisation declared a pandemic.
Because the variety of folks contaminated with the SARS-CoV-2 coronavirus grows, so does our data of the way it spreads, the way it impacts the physique, and the vary of signs it causes.
Listed here are a number of the uncommon issues we’ve discovered concerning the coronavirus alongside the way in which.
Coronavirus: how lengthy does it take to get sick? How infectious is it? Will you at all times have a fever? COVID-19 fundamentals defined
1. It impacts how your blood clots
Many inflammatory illnesses, together with infections, are related to an elevated threat of creating blood clots. Nonetheless, COVID-19 is extra strongly related to blood clots than many different infections.
If blood clots are giant sufficient, they will block the circulation of blood by a blood vessel. This in flip results in the a part of the physique the blood vessel provides being starved of oxygen.
If this occurs in a coronary artery, which provides blood to your coronary heart, it will possibly trigger a coronary heart assault. Within the lungs, it will possibly trigger a pulmonary embolism. Within the mind, it will possibly trigger a stroke, which now we have seen even in younger folks with COVID-19 however no different threat elements.
Individuals with coronavirus are liable to blood clots and strokes. Here is what we all know thus far
Critically unwell COVID-19 sufferers in intensive care items (ICU) are notably liable to blood clots.
One research discovered 49% of sufferers had been affected, primarily with clots to the lungs. Different research discovered 20-30% of critically unwell COVID-19 sufferers had blood clots.
These charges are a lot greater than we’d count on to see in sufferers admitted to ICU for different causes.
Worryingly, clots happen in COVID-19 sufferers regardless of utilizing customary preventative measures equivalent to blood-thinning medication.
2. You’ll be able to lose your sense of odor
We now know COVID-19, like different viral infections, can result in anosmia, or shedding your sense of odor.
In a single research, it affected about about 5% of sufferers in hospital with COVID-19. However some folks with solely very gentle illness say they they’ve instantly misplaced their odor, earlier than regaining it.
Anosmia has now been added to the listing of attainable COVID-19 signs.
Coronavirus may trigger lack of odor, or anosmia. Nevertheless it in all probability will not be everlasting
Anybody who’s had an everyday chilly is aware of nasal congestion can have an effect on your sense of odor. However COVID-19 is totally different. Individuals can lose their odor with out a runny or blocked nostril.
Maybe the virus latches onto receptors within the lining of the nostril earlier than getting into the cells. We all know these ACE2 receptors are how the virus enters different elements of the physique, together with the lungs.
Some folks with COVID-19 who lose their sense of odor additionally report a discount or lack of their sense of style.
3. It may well set off severe inflammatory illness in children
One other uncommon characteristic is how little COVID-19 seems to have affected kids, in contrast with many different respiratory infections.
Nonetheless, medical doctors in Europe and the UK, who’ve seen bigger numbers of COVID-19 in kids, have seen an uncommon however severe inflammatory situation in kids with the virus. This is called “multisystem inflammatory syndrome in kids”, or MIS-C.
In research from the UK, Italy and France, many of the kids with this severe situation possible had COVID-19 previously.
A mysterious sickness is placing kids amid the coronavirus pandemic – however is it Kawasaki illness?
Signs fluctuate. However the principle ones embrace fever, rash and intestine signs (vomiting, belly ache and diarrhoea). Some kids develop coronary heart issues.
These signs usually resemble different circumstances equivalent to Kawasaki illness and poisonous shock syndrome.
Researchers suppose it’s not the virus itself that’s chargeable for MIS-C. As a substitute, they suppose it’s the physique’s immune response to the virus, maybe lengthy after being contaminated.
4. It may well journey from people to animals and again once more
At first of the pandemic, we believed SARS-CoV-2 originated from animals earlier than spreading into people. Nonetheless, we had been uncertain if the virus may journey again into animals, maybe infecting our pets.
We now know people can transmit COVID-19 to home or captive animals, equivalent to canines, cats and even tigers.
Within the Netherlands, there have been outbreaks in animals at a number of mink farms. Researchers consider an contaminated employee launched the virus to the farms. The mink developed viral pneumonia, which unfold among the many animals.
Sick mink then reportedly contaminated two folks – the primary documented case of animal-to-human transmission after the virus originated in China.
Can your pets get coronavirus, and might you catch it from them?
