Scientists say insect repellent kills surface SARS-CoV-2 coronavirus

The pandemic of coronavirus disease (COVID-19) is widespread worldwide, affecting more than 24.1 million people and killing more than 825,000 people. There is no known vaccine or cure for COVID-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but physical distance, proper hand hygiene, and wearing a mask are known to prevent infection Method.

Now a team of British scientists National Institute of Defense Science and Technology (DSTL) Sharing the preliminary findings of their study, they showed that an insect repellent product can kill the SARS-CoV-2 virus.

Defense scientists have asked whether insect repellents provide a protective layer against COVID-19, which is a naturally-occurring, clinically proven insect repellent and Citrefine International Ltd’s flagship product, citridiol. I investigated.

Insect repellent research

In this study, which has not yet been peer-reviewed, DST was commissioned by the MoD Director General of Surgeons to test the antiviral activity of citriol and the Mosi-Guard Natural spray for the SARS-CoV-2 virus. The team has announced two trials. The test was conducted by Protondown by a British government research institute.

The team has taken two approaches to product antiviral activity. Evaluation of the product when applied directly to the virus as droplets and after application to latex synthetic skin.

trial

For standard assays or liquid contact, the team mixed the virus suspension with Mosi-guard Natural spray. Alternatively, selected components reduced the SARS-CoV-2 strain, England-2, and separated the titers after only 1 minute.

In the first trial, a product previously sold as an insect repellent containing 30 percent citriol was found to have a significant impact on SARS-CoV-2. Even with a slight dilution of the mixture, the product showed at least 99.99 percent inactivation of coronavirus within only 1 minute. In the test, there were 10,000 live virus particles, but in just 10 minutes, the number was reduced to 10 active particles.

In the second test, the team investigated the effect of Mosi-guard Natural on the surface. The researchers chose to dry the alcohol in the product, which could interfere with results. They found that the product reduced surface viruses almost instantaneously by up to 99% and continued to inactivate the remaining particles for the next 4 hours. After 4 hours, approximately 99.99% of the virus particles were inactivated.

“We’re very excited about these findings and some new research is already in the lab or is planned,” said Jacqueline Watson, Citrefine’s managing director.

The team said the experiment used a SARS-CoV-2 England-2 isolate isolated from a British patient obtained from British Public Health England (PHE) Colindale.

“Other isolates may behave differently within the described design, but all isolates and subsequent passages are expected to behave similarly,” the researchers say. It was

Sky News Report That the army has been given insect repellents that may provide a new layer of protection against coronavirus disease.

What is Citriol?

Citriodiol® is Eucalyptus citriodora An oil containing the main component, p-menthane-3,8-diol. Formulations containing Citriol ® are widely used as mosquito repellents. The main component of Citriodiol® is p-menthane-3,8-diol (PMD).

This product is considered the most effective insect repellent and is an active ingredient of natural origin against some stinging insects. It is derived from the oil of Eucalyptus Cirtriodora Also called a tree Corymbia citriodora..

Status of COVID-19

The COVID-19 pandemic currently reaches 188 countries and territories, with the United States and Brazil being the hardest hit countries. In the United States, more than 5.8 million people have been infected with the coronavirus, and more than 179,000 have died. In Brazil, at least 3.71 million have been confirmed and more than 117,000 have died.

More than 3.3 million cases continue in India and Russia, affecting at least 968,000 people.
