However, it is believed that the first symptom of cod coronavirus is fever or dry cough, but this is not necessary, as it can lead to loss of sense of smell or taste.
This was revealed in a new medical study in Italy.
The study included 93 patients who were hospitalized with cod in March 2020 but did not need an ICU.
The study found that two-thirds of patients reported loss of sense of smell and taste, and about 25 percent said it was the first sign of the disease.

The virus was confirmed in these individuals by PCR tests or X-rays or scans of the lungs.
When asked about the symptoms during the study, 63% reported loss of sense of smell and taste.
The total number of people was 58, of whom 13 described it as the first sign of the disease.
The researchers also found that the average duration of loss of sense of smell and taste was 25 to 30 days.
Experts from the University of Misericordia Hospital involved in this study said that loss of sense of smell and taste is common in people with cod and our research found that this symptom often precedes other symptoms such as fever or difficulty breathing. Is.
The study’s findings add to the findings, which say that loss of sense of smell and taste is one of the earliest signs of the virus.

A recent analysis of eight research reports on more than 11,000 people found that the rate was between 74.9% and 81.3% in patients who lost their sense of smell and taste.
The analysis also found that in more than 50% of people, the symptom preceded other symptoms.
A recent study by University College London included 590 people who lost their sense of smell or taste, and 80% of them were diagnosed with corona virus antibodies.
In 40% of people with these antibodies, no other symptoms were seen.
This means that it is also the first and only symptom in patients without code 19 symptoms.
Researchers in Italy say that given the results, medical experts should consider it the first sign of the virus in people who lose their sense of smell and taste, and isolate it to diagnose the problem with tests.
“Although cod 19 occurs in most people’s lungs, we discovered that it affects other areas as well,” he said.
Along with the symptoms, the researchers also looked at blood samples that did not contain specific signs of inflammation.
They found that people who lost their sense of smell and taste had lower white blood cell counts than patients with code 19 who did not have the symptom.
White blood cells help fight disease, and in the past research reports have linked white blood cell deficiency to serious cases of code 19 and the risk of death.
However, researchers say more research is needed to determine the extent to which white blood cell counts affect patients.
