According to the World Health Organisation (WHO), more than 205 million people have evolved COVID-19 since late 2019. Many other populations have possibly had the disease but never obtained a confirmed test result. Unless you go for an antibody test, you can’t get to know if you already have had COVID-19. And according to the research, even a positive antibody test arrives with a small chance of a false positive.
The most probable manner to acknowledge that you simply had COVID-19 is that if you had specific COVID-19 symptoms and approved a positive diagnostic COVID-19 test when falling sick. But actually, gold-standard PCR tests arrive with a possibility of a false-negative result, meaning you have COVID-19, but the test outcomes imply you do not.
If you didn’t get a positive COVID-19 test once you were sick, it’s tougher to understand if you had the disease.
New symptoms for early detection of COVID-19
There are no certain signs that you already had COVID-19. But there are some common symptoms you may have encountered, such as:
- loss of taste or smell
- pink eye
- fatigue
COVID-19 can impact various parts of your body and result in common symptoms that have many probable causes. Some people with COVID-19 don’t develop any symptoms that predict that they have coronavirus.
Most reported and Early signs of detection, symptoms according to CDC
According to Trusted sources of the Centers for Disease Control and Prevention (CDC), the following are the greatly reported symptoms:
- stuffy nose or runny nose
- body aches
- cough
- headache
- nausea
- diarrhea
- fatigue
- fever or chills
- new loss of taste or smell
- shortness of breath or trouble breathing
- sore throat
- vomiting
Is Sneezing also involved in COVID-19 symptoms?
COVID-19, earlier considered as the common cold, and flu can be tough to tell apart. Sneezing isn’t a sign of COVID-19 and may predict you had a cold or allergies with cold items. Briefness /shortness of breath isn’t a particular flu symptom but is one of the additional common COVID-19 symptoms.
You had pink eyes or other eye symptoms?
Coronavirus is believed to reach your cells through receptors for the enzyme called angiotensin-converting enzyme 2 (ACE2). The virus arrives at these receptors by cheating your body into believing it’s the ACE2 enzyme. ACE2 receptors are found in several parts of your eyes, such as your main eye area retina and the epithelial cells that thread your eye white and eyelid.
Particular eye symptoms of COVID-19
- pink eye
- dry eyes
- excessive tearing
- swelling
- increased eye secretions
Eye symptoms are usually supported by extra typical COVID-19 symptoms, but they’ll seem alone in some people.
Temporarily lost sense of taste or smell?
Losing taste or smell is generally reported in people with COVID-19. A survey of studies by an authorized Source found that loss of taste or smell was recorded in 47 percent of people and was most widespread in people with mild to moderate disease. Some people with COVID-19 also encounter a distortion of these senses. Signs affecting taste or smell appear to often seem before other symptoms.
A fever would be developed first
COVID-19 symptoms/signs often appear in a specific order. In a study released by the University of Southern California in 2020, researchers evaluated the evolution of symptoms in 55,000 people with COVID-19 and correlated them to the symptoms of 2,000 people with influenza. They discovered that influenza began with a cough, while the preliminary symptom of COVID-19 was most probable to be a fever.
A wide range of basic symptoms of COVID-19 has been recorded in scientific literature. Just because you didn’t cultivate a fever early doesn’t certainly mean you didn’t have COVID-19.
Is it probable to say if you had a variant of COVID-19?
There are four trusted Source critical COVID-19 variants in the United States titled after the initial four letters of the Greek alphabet:
- Alpha
- Beta
- Gamma
- Delta
- Lambda
These variants appear to scatter shorter than regular COVID-19, but the signs appear to be identical. For instance, a May 2021 study found that the Alpha variant wasn’t correlated to a change in self-reported symptoms among the population in the United Kingdom. Some variants may result in certain symptoms more often than other variants.
