Does having a cold help fight the emerging corona virus (Covid-19)? What is the relationship between walking speed and the likelihood of developing an acute infection with Covid-19? Do some Corona recoverers lose their sense of smell and taste forever? Corona?

We start from Britain, where scientists at the University of "Glasgow" (Glasgow) believe that the virus responsible for the common cold can prevent the reproduction of the emerging corona virus, "whose scientific name is SARS-Cove-2" that causes Covid-19 disease in the patient's body, according to a report published LCI website.

According to researchers at the University of Glasgow, the rhinovirus - which causes the common cold - that spreads in the winter, is stronger than the Corona virus, when both are present at the same time in the patient's body.

The scientists write that they have shown that the "human rhinovirus" stimulates the "interferon" response, which "blocks SARS-CoV-2 replication".

Scientists made several observations based on different scenarios.

The first scenario provides for the cold virus to be injected into replica copies of the respiratory system cells, and the virus that causes Covid-19 is injected 24 hours after that.

The result of this was the inability of the Corona virus to reproduce in the body, after it was prevented by the rhinovirus, which had already begun to develop.

Then the researchers repeated the experiment in the other direction, and first injected the virus that causes the Corona virus, then the one that causes the common cold.

The result was similar: a sharp decrease in the proliferation of SARS-Cove-2 was observed after infection with the rhinovirus.

Dr. Murcia, one of the study's authors, told "BBC News" that "the SARS-Cove-2 virus never reproduces, as the rhinovirus prevents it from doing so. The large spread of rhinoviruses can stop the emergence of new SARS infections." -Cove-2 ".

However, this does not mean in any way that a person seeks to catch a cold, or underestimates preventive measures and social distancing, or does not receive a Corona vaccination, according to the medical instructions in his country.

Walking speed and severe infection with corona

A scientific team from the Diabetes Research Center at the University of "Leicester" in England has found a relationship between walking speed and the risk of severe forms of Covid-19.

In a report published in the French newspaper "L'OBS", writer Jean-Paul Fritz says that the study published by the team in the International Journal of Obesity showed that people who walk at a slow pace suffer from greater risks when infected with the emerging corona virus.

Although what comes to mind directly when thinking about slow walking, is obesity and excess weight;

However, the British study showed that the two factors are completely separate regarding their effect on Covid-19 patients.

In the British study led by Professor Thomas Yates, researchers examined data from more than 412,000 middle-aged people from the UK Biobank database.

In order to understand the exact relationship between BMI, the risk of acute COVID-19 infection, and the risk of dying from it.

According to the study, "obesity and walking speed separately affect the risk of infection with Covid-19 and the death resulting from it," and this means that "those who walk slowly are most at risk, regardless of their obesity."

And it was found through the study that people of normal weight, who walk slowly, are about two and a half times more likely to develop a severe form of Covid-19, and are 4 times more at risk of death compared to people who walk at a fast pace.

And what is surprising - according to what the study reveals - that a person who has a normal weight but walks slowly, is more likely to have Covid-19 compared to a person who is obese and walks at a fast pace.

According to this study, obesity is a factor that increases the risks related to Covid-19, but its effect is completely separate from the speed of walking.

According to the hypotheses put forth by the new study, people who are very thin and who do not have strong immunity often walk at a slow pace, and therefore they are more susceptible to severe forms of Covid-19.

Do some Corona recoverers lose their sense of smell and taste forever?

After 3 days of monitoring her infection with the Coronavirus, Elizabeth Medina lost her sense of smell and taste at the beginning of the pandemic in March 2020, and a year later, the 38-year-old American fears that she will never recover these two senses.

This study consultant at a New York school consulted doctors of different specialties, from ear, nose and throat to neurologists or surgeons, as well as used nasal sprays and joined a group of patients trying a treatment prepared from fish oil.

To stimulate the sense of smell, Elizabeth puts large quantities of spices in her dishes, and aromatic herbs in tea, and does not stop smelling a bracelet perfumed with essential oils, according to an AFP report.

But these efforts have been in vain, as this mother of two says that she has lost many of the daily pleasures, including eating and cooking.

The situation also negatively affected her psychological condition, as she cried daily for months.

Elizabeth Medina belongs to a growing group of people with anosmia, a disorder that has remained unknown and whose significance has long been underestimated before it became a major symptom of COVID-19.

While most people who have lost smell and taste due to the Corona virus recover these two senses within 3 to 4 weeks, “these cases last for months at 10% to 15%,” according to Valentina Parma, a psychologist at Temple University in Philadelphia and a member of an international consortium of researchers who Pose at the beginning of the pandemic to analyze this problem.

And these disturbances affect at least two million people in the United States and more than 10 million in the world, according to Parma.

The senses of smell and taste are often seen as being less important than sight or hearing.

Although they are essential in social relations, "our partners are chosen partly on the basis of their scent," and doctors often see their loss as less dangerous than other consequences of what has become known as "long-term Covid".

But their loss is constantly accompanied not only by nutritional problems.

But also with cases of anxiety or even depression, according to Parma.

It is now known that the development of anosmia into what is known as parosmia, which is reflected by incorrect recognition of odors such as smelling a foul odor when drinking coffee, for example, may be a good indicator of long-term recovery.

It has also become known that daily practice of "smelling" different scents, such as essential oils, constitutes at this stage the only treatment recommended without reservation, as it has proven successful in approximately 30% of cases after 3 to 6 exercises, according to the researcher.

 Does the weather affect the rates of corona spread?

In a report published by the French newspaper "Le Figaro", writer Tristan Faye says that the rates of the epidemic remained under control last summer despite the gradual lifting of the lockdown measures, which reinforced speculation that the weather is greatly affecting the spread of the new Corona virus, especially All other respiratory infections are weather related.

The author explains that given that we spend most of our time during the summer in the fresh air and open the windows continuously, and because viruses do not like ultraviolet rays, and the respiratory mucous membranes are less fragile, and our immunity is stronger, respiratory viruses spread more in the winter, and it does not appear to be Covid -19 Exception.

A French study has shown that subtle climate differences from one region to another also influence the spread of the virus.

The researchers from the Valenciennes Hospital Center studied the prevalence of the epidemic in 5 different French regions in terms of weather (north, east, the Atlantic coast, the center of the country, the Alps, and the Mediterranean basin).

Mehdi Majdoubi, professor of medicine at Valenciennes Hospital Center and lead author of the study, confirms, "We took into account the population density and the number of people over the age of 60 in each region, and we noticed that the climate factor clearly affects the development of the epidemic."

In another study, researchers from Aix Marseille University and the Pasteur Institute in Paris tried to study the effect of temperature and humidity on the way the epidemic spreads.

The researchers analyzed the first wave data, in March 2020, in 63 regions of 6 countries with a temperate climate in the northern hemisphere, namely France, Spain, Italy, Portugal, the United States and Canada, and it was found through the study that the lower the temperature, the higher Infection rate.
