Shafaq News / Experts and doctors in infectious diseases confirmed that the Corona virus may have infected millions around the world without realizing it, before the start of the closure measures applied by many countries, starting from mid-March.
"Most people infected with Coronavirus have an uncomplicated case of infection, and it may not be distinguished from cold or flu," said an expert in infectious diseases, Amesh Adalja of the Johns Hopkins Center for Health Security
Unfortunately, "there is no 100% sure method to know if the infection you dealt with last winter was" Covid 19 "or a common cold," according to doctors.
However, 7 signs can be viewed that indicate that many people may be infected with Covid 19 without realizing it.
1- A cold in early 2020
Scientists discovered that for every two cases of flu, one case was found with the Coronavirus.
While it may be difficult to distinguish between a cold and a mild case of "Covid 19" due to the similarity of symptoms, colds do not usually cause shortness of breath or severe headaches.
2- lost the sense of smell and taste
Loss of smell and taste is a distinctive feature of infection with the Coronavirus, and this symptom does not happen to everyone, but Adalja indicated that it is now strongly linked to "Covid 19".
It should be noted that it is also possible to lose these two senses temporarily in such as cold, influenza, sinusitis, or even with seasonal allergies.
3- Hair loss
Many of those who recovered from the Corona virus reported problems related to hair loss, and Adalja said that the reason for this could be a combination of factors, including severe stress, weight loss and Covid 19.
4- Shortness of breath
Research published in the scientific journal "Gamma" found that people with coronavirus may feel short of breath, possibly due to an infection in the lungs.
5- A persistent cough
A persistent cough is one of the symptoms of infection with the Coronavirus, and the cough is often dry in this case, which means that no mucus appears, according to Dr. Adalja.
The data found that 43 percent of people who contracted Covid 19 had a cough from 14 to 21 days after getting a positive test for the virus.
6- Feeling overwhelmed
The study, published in the Gamma Journal, found that 53 percent of coronavirus patients said they experienced fatigue and exhaustion about 60 days after signs of the virus first appeared.
7- Symptoms that do not go away
Corona virus is still new to doctors, so some of its symptoms and consequences are still hidden, such as the suffering of some people with the virus from heart problems after infection.
