STUDY SAYS OMICRON LIVES ON SKIN FOR NEARLY A DAY AND ON PLASTIC FOR OVER A WEEK.

By -


According to a study, the Omicron variety of coronavirus may survive on skin for more than 21 hours and for more than eight days on plastic surfaces, which may contribute to its faster spread than other strains.

The differences in viral environmental stability between the SARS-CoV-2 Wuhan strain and all variants of concern were investigated by researchers from Kyoto Prefectural University of Medicine in Japan (VOCs).

The Alpha, Beta, Delta, and Omicron variations had more than two-fold longer survival on plastic and skin surfaces than the Wuhan strain, according to the study, which was just published on the preprint repository BioRxiv.

According to the study's authors, "the high environmental stability of these VOCs could raise the likelihood of contact transmission and contribute to their spread."

"This analysis found that Omicron has the highest environmental stability among VOCs, which could be one of the reasons for the variant's rapid expansion and replacement of the Delta variant," they wrote.

The original strain, as well as the Alpha, Beta, Gamma, and Delta variations, had average survival durations of 56 hours, 191.3 hours, 156.6 hours, 59.3 hours, and 114 hours on plastic surfaces, according to the study.

According to the researchers, this compares to 193.5 hours for the Omicron variety.

They found that the original virus survived for 8.6 hours on skin samples, 19.6 hours for Alpha, 19.1 hours for Beta, 11 hours for Gamma, 16.8 hours for Delta, and 21.1 hours for Omicron.

According to the researchers, there was no significant difference in survival periods between Alpha and Beta versions, and they exhibited equal environmental stability, which is consistent with prior studies' findings.

Although all VOCs on the skin surface were totally inactivated by 15 seconds of exposure to 35 percent ethanol, Alpha, Beta, Delta, and Omicron variants showed a small increase in ethanol resistance in response to increasing environmental stability.

"As a result, current infection control (hand hygiene) methods should utilise disinfectants... as recommended by the World Health Organization," the researchers concluded.

Because of the rapidly increasing number of infected people around the world, the Omicron strain is currently a big issue.

SPACE AGENCY SAYS CHANDRAYAAN-2 ORBITER DETECTS SOLAR PROTON EVENTS ISRO

  Mumbai: The Indian Space Research Organisation (ISRO) announced on Wednesday that the Large Area Soft X-ray Spectrometer (CLASS), a payload on board the Chandrayaan-2 Orbiter, had discovered solar proton events (SPEs), which considerably increase radiation exposure to humans in space. Coronal mass ejections (CMEs), a tremendous torrent of ionised material and magnetic fields that reach Earth a few days later, causing geomagnetic storms and lighting up the polar sky with auroras, were also observed by the sensor on January 18. According to the ISRO, such multi-point measurements helps in the understanding of propagation and its impact on various planetary systems. Solar flares are dramatic explosions that occasionally spew out energetic particles (called Solar Proton Events or SPEs) into interplanetary space when the Sun is active. The majority of these are high-energy protons that have an influence on space systems and increase radiation exposure to astronauts. According ...

  BCCI president and previous India captain Sourav Ganguly has been conceded to a city clinic in the wake of testing positive for COVID-19, the cricket board sources said on Tuesday. Ganguly is two immunized and has been voyaging broadly, participating in every expert movement. The 49-year-old was hurried to a medical clinic late on Monday night as a prudent step later his RT-PCR test brought positive back. "He was taken to Woodlands Nursing Home final evening. He has been given medicine and is as of now steady," a BCCI source, who is monitoring Ganguly's wellbeing, told PTI. Ganguly was conceded to clinic two times recently and went through crisis angioplasty subsequent to having some heart issues. His senior sibling Snehasish Ganguly had additionally tried positive for COVID early this year.
