Lose your smell can be an early brand of a COVID-19 [female] Infection - and a new to study identified why, for some people, this symptom may last long after initial infection as a sign of Long .

"The sras-cov-2 causes deep changes in the direction of the smell, including the total loss of the odor. Although these modifications are often transient, many patients with COVID-19 have an olfactory dysfunction which lasts from years to years, "explains the new study, published in December 21 in Scientific Translation Journal .

Researchers have found that a very specific type of inflammation can be blamed for this condition, also called anosmia. Read the rest to see what exactly they discovered and how you can stay safe.

Scientists "analyzed the biopsies of the olfactory mucosa collected from COVVI-19 patients with loss of persistent odor using RNA sequencing and a unique immunohistochemistry".

In secular terms, they gathered samples of nose tissue, 24 in fact, patients who have a long -term loss of odor from the cocovan, and compared them to those who have never been cocovated But have lost their odor of their smell).

The "biopsies of hyposmic individuals had less olfactory sensory neurons and populations of altered immune cells, including T cells producing" ... populations of altered immune cells in olfactory epitheliums contribute to a loss of long odor term after covid-19 ".

"The results seemed to be striking enough for us - there are really very obvious differences," said Dr. Bradley Goldstein, a Duke neuroscientist who directed research, according to the Seattle Times .

He summed it up as a kind of inflammation. "I am not talking about this kind of severe and severe nasal inflammation where you are super congestioned, blowing your nose and feeling as if you were sick," he said. "It's more at the local microscopic level."

This new research can lead researchers to find a remedy.

Even before covid, people viral infections lost their smell. There are several different mechanisms by which viruses can cause loss of odor. AE0FCC31AE342FD3A1346EBB1F342FCB

One way consists of a direct cell infection responsible for the detection and transmission of odors, which are called olfactory neurons. These neurons are located in a small plot of fabric in the upper part of the nasal cavity called olfactory epithelium. Olfactive neurons are sensitive to viruse infection, and if they are damaged or destroyed, this can cause loss of odor.

Another way in which viruses can cause loss of odor is inflammation of nasal passages or sinuses. As the study shows, many viruses, including the Sars-Cov-2 virus which causes COVID-19, can cause inflammation of nasal passages and sinuses in the context of the body's immune response to infection. This inflammation can hinder the flow of air and mucus through nasal passages and make odors difficult to reach olfactory neurons.

It is also possible that a loss of odor is a symptom of a more general disease or condition which is not directly caused by a virus, such as allergies, nasal polyps or certain drugs. In these cases, the underlying condition may have to be treated in order to restore smell.

Long Covid, also known as the Post-Aiguë Covid-19 syndrome or COVID-19 "long term", refers to the persistent symptoms that some people experience after recovering from COVID-19, the disease caused by the virus SARS-COV-2.

These symptoms can go from light to severe and last several weeks or months after the initial infection. The most common symptoms of the long cocoat include:

Fatigue or fatigue

Shortness of breath

Chest pain or discomfort

Headache

Muscle or joint pain

Difficulty sleeping

Loss of taste or smell

Brain fog or difficulty concentrating

Depression or anxiety

Heart palpitations

Other possible symptoms of the long cocvation include fever, cough, sore throat and loss of appetite.

Some people may also experience difficulties in returning to their normal level of physical or mental function or may have continuous symptoms that disrupt their daily activities.

It is important to note that the symptoms of the long cocoan can vary considerably from person to person, and that all those who have had COVID-19 will not feel long-term symptoms.

If you feel persistent symptoms after you recover from COVID-19, it is important to speak to your health care provider for more in-depth assessment and treatment.

Winter trips and China's lifting of its "zero cocvid" policy is released in an increase in the case -on -the -way in the world. There are several steps you can take to protect yourself and protect others from COVID-19:

Mask : Wearing a mask or a face cover can help reduce the spread of the virus, especially when combined with other preventive measures. It is important to use a mask that covers your nose and your mouth and wear it properly, ensuring that it adapts perfectly against your face.

Practice good hygiene : Wash your hands frequently with soap and water for at least 20 seconds, or use a disinfectant for alcohol-based hands. Avoid touching your face, especially your eyes, nose and mouth.

Keep your distance : Maintain a distance of at least 6 feet of the others whenever possible.

Avoid large gatherings : Limit your contact with others as much as possible, especially in overcrowded or closed spaces.

Stay at home if you're sick : If you feel symptoms of COVID-19 or if you have been exposed to a person with virus, stay at home and self-isolated to prevent the spread of infection to others.

To get vaccinated : Having vaccinating can help you protect yourself, you and those around you, from COVID-19. Vaccines are effective in reducing the risk of serious disease and virus death and can help slow the propagation of the virus in the community.

By following these steps and remaining informed of the latest recommendations and advice, you can help yourself protect yourself and the others from COVID-19.
