The coronavirus family is responsible for respiratory infections in humans, and two of them are responsible for severe and potentially fatal pathologies: the SARS-CoV-1 and the MERS-CoV.
In December 2019, the occurrence of several cases of pneumonia of unknown origin in China led to the identification of a new coronavirus, named SARS-CoV-2.
SARS-CoV-2 causes a severe respiratory disease, named “COVID-19” by the World Health Organization. After Asia, Europe, the United States, and Iran are the most affected regions in the world.
SARS-CoV-2 is more easily transmitted than seasonal influenza virus, but the progression of the epidemic is not the same. Influenza invades a territory in a uniform manner whereas COVID-19 seems to be more dependent on the existence of significant foci of infection. Here are 6 Signs That You May Have Already Had COVID-19.
6. Sore throat
One of the main symptoms of coronavirus is actually a sore throat. Covid patients most often present a dry cough, but it can also sometimes be greasy. However, in the majority of cases, this cough goes away by itself. The WHO advises to call your doctor if you have a dry cough.
5. Digestive disorders
Digestive disorders such as nausea, vomiting and especially diarrhea have been described more frequently in geriatric settings than in the rest of the population; the first alerts on this point in France were issued by geriatricians working in residential facilities for dependent elderly people.
According to a study published in the scientific journal Springer Link, 16% of patients infected with SARS-CoV-2 had only gastrointestinal disorders (Nausea; Vomiting; Diarrhea; Abdominal pain).
4. Covid tongues
A recent symptom has been identified by epidemiologist Prof. Tim Spector of King’s College London (UK). It is an affection of the tongue in some patients contaminated by Covid-19.
He posts on his Twitter account “One in five people with Covid still present with less common symptoms that dont get on the official PHE list – such as skin rashes. Seeing increasing numbers of Covid tongues and strange mouth ulcers . If you have a strange symptom or even just headache and fatigue stay at home !”

3. losing your sense of taste and smell
Covid-19, caused by the SARS-CoV-2 virus, is primarily a respiratory disease, but many patients have extra-respiratory symptoms. Among these, a sudden loss of sense of smell in people infected with SARS-CoV-2 has been reported worldwide.
The most frequent symptoms are loss of sense of smell and taste dysfunction, especially in young people. The first one is observed in 70.2% of the patients and the second one in a little more than half of the people tested positive to the virus.
2. losing your sense of hearing
After the loss of sense of taste and smell, a sudden and permanent hearing loss, although rare, could indeed be related to Covid-19 in some people.
According to the medical community, this is the “first British case of sudden sensorineural hearing loss after Covid-19”. They link the infection to this hearing loss since “clinical examination and imaging ruled out any other cause” for this symptom.
