According to the WHO, more than 200 million individuals have been infected with covid 19 since late 2019. Many other people might have contracted the virus but without their knowledge or even a confirmed test result.  A person may get a coronavirus infection without knowing it unless they undertake an antibody test. Therefore in the UK, for every traveller, an antigen fit to fly test is mandatory. The best way to know if you have the infection is if you had serious symptoms of the virus. Another can be if you received a positive diagnostic covid 19 test when you fell sick.

However, people should understand that sometimes you may receive a false-negative result. It means that you may have covid 19, yet the results indicate that you don’t have it. Infectious disease expert Amesh A. Adalja, M.D says that most people who have Covid 19 have an uncomplicated case of infection. It could be indistinguishable from influenza. Again, some people have no symptoms at all according to estimates from the centres for disease control and prevention. Although, it is easy to buy a test kit from a government-approved list of providers. This is just like buying medicine online. It is easy, and safe and the results require less time. 

Symptoms of Coronavirus

So, is it possible that you might have contracted COVID 19 without even realizing it? Are there any symptoms or signs that should be a guarantee that you might have contracted the COVID 19 virus? Can you tell if a person has coronavirus? The answer to all these questions is YES! According to experts, there are several signs that can be dubbed a red flag. These indicate that you might be having or you already had COVID 19 in your body. Many asymptomatic patients never knew that they were infected with the coronavirus until they took a mandatory antigen fit to fly test before boarding a plane. Here come the top signs from the specialists, that indicate fully that you may have had COVID 19.

Having lost the sense of taste and smell

The biggest signs that indicate the presence of COVID 19 in one’s body are the loss of taste and smell. Dr Adalja says that this symptom does not occur to everybody with COVID 19. Still, this symptom has strong links with the novel coronavirus. It’s important to note that it’s also possible to experience this symptom if one has other respiratory infections. Infections could be due to sinus, seasonal allergies, colds or even flu. Experts also say that this sign can stay with some people for months even after recovering from COVID 19. Apart from that, a person can get reinfected with coronavirus’ new strains. Testing is the key to detecting the virus at its early stages. 

Hair loss without a reason

Although it has not been openly studied in the view of COVID 19, most people who have recovered from this disease have been reporting issues of unexplainable hair loss. There are physical and mental effects of corona infection. For example, a famous actress by the name of Alyssa Milano, who had contracted the virus shared a video of herself on her Instagram page, whereby she was repeatedly brushing out large clumps of hair after taking a shower. Dr Adalja however says that it can happen due to the telogen effluvium condition. Its causes are several other factors including weight loss, pregnancy, and even extreme stress, and not just COVID 19 illness. He, therefore, states that if anybody is experiencing hair loss, it could be due to an unknown COVID 19 illness, or extreme stress which have been brought up by the pandemic.

Shortage of breath

Certain research has found out that people with this COVID 19 virus may feel breathless sometimes, which is a symptom that nobody understands the period it lasts but can occur due to a long period of inflammation of the lungs. Dr Schaffner tells people that this symptom is one of the clear signs of people with this virus. So if anybody experiences this, then it might be they have or had this virus with them. Experiencing long coughs is another long-lasting symptom. A study that was carried out on people who had contracted COVID 19, showed that such people experienced a cough for a period between 14 to 21 days after receiving their positive test results. Although, it is a dry cough.

An antigen fit to fly test can detect any coronavirus infection before you travel. Even though you do not have any shortness of breath or cough, you can still have the infection. 

Fatigue and other symptoms.

This symptom occurs after one has suffered from COVID 19. According to the JAMA study, 53% of patients were found to have experienced this symptom, 60 days after they first showed the signs of this virus. Dr Adalja tells people that it’s not yet confirmed why people experience this symptom after contracting the virus but explains that it might be one of the ways in which an individual’s immune system reacts to the virus. As mentioned earlier a person once infected can get infected again. Therefore, it is always good to keep testing yourselves with self-testing kits that can be purchased from any government-approved list of suppliers. 

Other Symptoms

Experiencing unending symptoms that cannot even be explained. According to experts, COVID 19 is still a new infection that they have not completely been able to master. Its therefore clear that most of the symptoms that people may be experiencing may mean that they have had this virus, yet others may not be a sign of the same. There is a list of many other symptoms that might have not been mentioned in this article since the virus is still under study. The best thing to do is if you feel off and don’t understand those feelings, just go for a checkup so as to avoid any inconveniences.
