Some people with new coronavirus infections have lost their sense of smell, and experts say they may not be able to return to normal olfactory capacity for life, according to new research. In early March, Isabelle Rosa, a 27-year-old California resident, began to experience some unusual symptoms after she thought it was just a normal flu, but as she continued to have a fever and a dry cough, as well as a growing outbreak of the new coronavirus in the United States, she began to suspect that she might be infected with the virus, according tomedia reports.

Unfortunately, as many U.S. residents experience, doctors tell her via telecommunication that as long as the symptoms are not obvious, it’s best to stay at home without any tests.
Although Rosa’s symptoms were not life-threatening, it did become even more strange, and after three days of persistent fever and dry cough, she suddenly realized that she couldnot smell or taste any food, “and suddenly I found myself drinking spoiled milk, but I couldn’t taste it, and my sense of smell was wrong, I couldn’t smell something like perfume, I ate a lemon, I didn’t respond, and then I smelled about 50 different substances, tasted more than 30 kinds of food, and a week passed.” Still can’t restore your sense of smell and taste. “
In recent weeks, Rosa has not been the only person suspected or confirmed to have the new coronavirus, with many patients showing loss of smell or taste, and news reports about people experiencing such conditions as the epidemic sweeps the globe. But how exactly do these strange symptoms come about? Will these unique symptoms have a greater impact on the way we track the disease?
There are many reasons for the disappearance of the sense of smell or taste in humans, which are known as loss of smell and loss of taste (both of which usually occur at the same time due to the serious impact of human sense of smell). People may be born with congenital diseases, may have neurological diseases or traumatic injuries that cause the brain to lose the processing of cranial nerve information in the olfactory ball (between the nose and brain), or people infected with the virus may also develop the above. When people are infected with the virus, they are usually recorded as respiratory diseases, such as a new coronavirus.
Olfactory loss is unlikely to be caused by a blockage of the nasal cavity and is not a sign of severe brain damage. Respiratory viruses can cause damage to the olfactory receptor, which is necessary for normal olfactory, olfactory loss usually does not produce pain, when nerve function is impaired, people do not necessarily have a particularly serious nasal congestion, when the nose is blocked, such as: cold, smell will temporarily weaken, which is very common, but when the nasal cavity is blocked after the end, the condition is often also resolved.
While there is little loss of smell in new corona patients in Germany, Iran and the United States, public health experts have recently begun to pay attention to the phenomenon. World Health Organization officials said they were beginning to study the correlation, but warned that any evidence of such correlation was at an early stage and needed to be analysed in depth.
There are still many unknowns about the relationship between neo-coronavirus and loss of smell, the first key question is whether patients with neo-coronavirus infection are more likely to develop loss of smell than patients infected with the typical influenza or cold virus, and the second key question is whether the complications of the new coronary virus infection are more serious or longer-lasting than those infected with the virus.
It has been shown that once this loss of smell occurs, people’s sense of smell decreases significantly, or even completely, and continues for a long time after the nasal congestion disappears, some olfactory loss may improve over time, but it is worrying that most olfactory loss may be permanent.
Experts are not sure whether the new coronavirus causes more loss of smell than the cold virus, but instead it may be that a surge in cases and the world’s attention to the new coronavirus have prompted them to speak out about their symptoms. But loss of smell is likely to be a basic signal of new coronavirus infection.
While the best way to track and analyze a new coronavirus is to conduct extensive testing and genetic analysis of the virus’s evolutionary history, finding people with lost sense of smell is a weather vane for a rough track of when a resident of an area is infected with the new coronavirus. Although he hasn’t studied the program in detail, researchers have taken to social media to explore and predict trends in the flu season. Otolaryngologists suggest that loss of smell may be a warning sign that doctors actively screen.
Public health experts’ lack of early attention to the symptoms of loss of smell in patients with new coronary crowns reflects the widespread neglect of the population of olfactory loss, and while the new coronavirus is not highly deadly, the infection is terrible and can completely change people’s lives.
Although people with loss of smell may regain some or all of their olfactory ability, the treatment process may last for several years, if 20-something saves at the loss of olfactory ability due to the infection of the new coronavirus, in the next 50-60 years of life, it is likely that there will be no recovery of the sense of smell, life will become very bad, seriously affect their quality of life, so it is hoped that people know more about this potential risk, as far as possible to avoid infection with the new coronavirus.
