British otolaryngologists warn society that loss of smell and taste are one of the most distinctive symptoms of COVID 19. And such a statement is confirmed by a number of studies.
Experts around the world and especially from China say that every third patient, who got positive COVID-19 test result, complained about a loss of taste and smell. This condition is called anosmia and sometimes occurs with viral diseases. In 30% of COVID cases, anosmia with coronavirus was observed as the main symptom.
Infected celebrities also faced to loss sense of smell with a coronavirus. In particular, Rudy Gobert, who plays in French basketball team, complained about it.
On his Twitter account, Rudi Gobert asked followers if they heard about loss of smell and expressed his concerns that this is a real sign of coronavirus.
Is loss of smell and taste with a coronavirus a key symptom?
It is already considered a full COVID-19 sign, although not all patients have this symptom. Scientists from the University of California presented the results of a new study, according to which violations of sense of smell are more likely to lead to mild or moderate form of COVID-19.
The team conducted a retrospective study. 169 volunteers who are infected with SARS-CoV-2 took a part in the study at San Diego. Clinical data from patients also show that loss of smell can be an independent sign of COVID-19.
Coronavirus infects the cells of the respiratory system and causes edema. With swelling of the mucosa, there is a loss of connection between receptor cells and nerve endings. Because of this, taste gradually disappears and the person lose sense of smells.
Perhaps such cases indicate a strong immune response in this part of the respiratory tract, limiting its spread further. This reduces the risks of more severe and rapidly developing pneumonia.
During a pandemic, you need to be careful about your health. If you experience a loss of taste or smell, seek medical attention.
Inability to distinguish tastes and smells is not the only factor
Scientists have noticed that anosmia with coronavirus is not the only indicator of COVID-19 and is accompanied by other symptoms.
- Half of studied patients had nasal congestion on the amid major symptoms like high temperature, confusion, and coughing.
- About 35% of infected had among the symptoms a runny nose.
Previous studies have shown that such a symptoms were not the key ones with COVID-19. In most cases, they were connected to allergies. It just means that people need to be more aware of the COVID-19 symptoms.
Loss of smell lasts for many days at a coronavirus: will sense of smell return after coronavirus?
Absence of taste and smell during infection with coronavirus on average appears on the third day. This side effect of positively tested for COVID 19 is caused by edema, so after recovery, these coronavirus signs disappear and the patient can again distinguish tastes and smells.
