Loss of smell and taste are common in people who have Covid-19 infections and now a new study found that these symptoms often occur before other symptoms, like fever or shortness of breath.
According to the study, published in the journal Neurology, almost two-thirds of the people admitted to an Italian hospital with Covid-19 in March experienced losing their senses of smell and taste,
Additionally, about 22 per cent of those with an impaired sense of smell and taste said it was their first symptom of infection.
“While many people show evidence of Covid-19 infection in the lungs, we found there could be more at play than what a person’s lungs can tell us,” said study author Francesco Bax from the Santa Maria della Misericordia University Hospital in Italy.
The study involved 93 people with an average age of 63 who were admitted to the non-intensive Covid-19 unit of the hospital in March 2020.
The participants either tested positive for the virus with a swab test, or they showed signs of lung problems with a chest X-ray or scan. They were also interviewed about their symptoms.
Loss of smell and taste was present in 58 people, or 63 per cent of the group. For 13 of the 58, or 22 per cent, the loss of smell and taste was their first symptom. The average duration of the loss of smell and taste was 25 to 30 days. (IANS)
