Common Cold Can Boot Out Coronavirus: How?

Rhinovirus Helps the Body Become Immune To Sars-Cov-2 For A Short Duration

According to the researched done recently on the coronavirus, the viral pathogen, which is the cause behind the common cold, is said to help effectively eradicate the COVID-19 virus out of the cells of the body. Some of the viruses which are present in our environment and after entering a human host, they tend to compete against each other to be the one to cause an infection.

According to the scientists working at the University of Glasgow, it has appeared after multiple research experiments that the rhinovirus that causes a common cold in humans has been able to trump against the coronavirus pathogen when administered into the same host.

The benefits of this might be for a limited time duration, but as the rhinovirus is widespread in our surrounding environment, it could still help in suppressing COVID-19 infection. As the nose, throat, and lungs are consecutively present in our body, similar to a row of houses. Once a viral pathogen is able to enter the body, it is possible that the viral would not be able to penetrate into the soft tissues, or it is likely that the virus can easily get access to the body tissues and cause an infection.

Influenza, which causes the common cold, is one of the viruses which almost always cause an infection in the body alone. Other viruses, like adenovirus, have the capability to cause an infective reaction in the body alongside another virus.

Rhinovirus against Sars-CoV-2

Since the onset of the coronavirus pandemic, various researches have been conducted as there have been multiple speculations regarding the Sars-CoV-2 viral pathogen, which causes the coronavirus infection, and how it would be able to fit into the ‘virus-virus interactions.

Although during the coronavirus pandemic, social distancing protocols have been placed in effect all around the world to limit and slowed the amount of infectious spread meanwhile, it has made it much harder for scientists to study the rate of spread of infection.

The team of researchers working at the Centre for Virus Research in the city of Glasgow has done an experiment during which they took an exact replica of the soft tissue lining present in the trachea, which is made with the same physiological cells as in humans, and was later infected the common cold-causing rhinovirus and Sars-Cov-2 viral strain at the same time.

The experimental study revealed that the rhinovirus was successful in causing the common cold while competing against Sars-CoV-2. In case of rhinovirus is administered 24 hours prior to the Sars-CoV-2, the coronavirus would not be able to enter at all, and the common cold would be diagnosed. Meanwhile, if Sars-CoV-2 has a 24-hour head start against rhinovirus, a common cold would be the diagnosis.

After the experimental research, it has been concluded that Sars-CoV-2 is heavily inhibited by the common cold-causing rhinovirus. This proves that if an individual has a high prevalence of having rhinovirus in their body, and could be already infected with the common cold, then it would help in prevention against exposure to COVID-19 infection, even though it would be for a very short duration.

Similar kinds of effects have been previously observed during the swine flu pandemic in the year 2009, as rhinovirus was able to hinder the process of transmission of infection in various parts across Europe.

It has been revealed after further experimentations that when the rhinovirus causes the common cold, it automatically triggers an immune response in the infectious cells of the body, due to which the Sars-CoV-2 infected cells are unable to divide and spread around the individual’s body.

When the immune response was blocked by the researchers, the amount of COVID-19 virus was the same, as if the rhinovirus is not even present.

However, the coronavirus pathogen would be able to cause infection in the body as soon as the common cold had passed and the immunological response of the body has slightly calmed down. If an individual is to follow through with the administration of viable vaccines available across the globe, along with proper hygiene measures and social distancing, it could decrease the incidence of infection. However, the maximum preventive effects would be observed after administration of the vaccine.

The human rhinoviruses, which is the most frequently diagnosed cause of developing a common cold in people, have a very high transmission rate.
