Experiments in mice showed that the infection enters the body using proteins located in the nasal cavity.
 
Scientists from the United States managed to find out why people infected with coronavirus have a symptom of loss of smell, a study published in the journal ACS Chemical Neuroscience.
 
As a result of experiments on mice, it was possible to establish that the infection enters the body with the help of proteins that contribute to the recognition of odors. They are produced in the nasal cavity, and in older individuals, more such proteins are formed than in young ones.
 
If this mechanism is also true for people, then this study also makes it clear why older people are more susceptible to coronavirus infection.
 
Recall, scientists from the United States found that people aged are more susceptible to coronavirus due to the smaller amount of microRNA in the body.
 
It was also reported that in the general list of symptoms of coronavirus was another one that was recorded by physicians from the United States. These are skin rashes.
