Omicron Damages Lungs Less Than Other COVID Variants

When opposed to prior coronavirus variations, the Omicron type appears to produce fewer lung problems, which might explain why it induces less serious sickness.

The Omicron form caused fewer harmful infections in mice and hamsters in fresh experiments, and it looked to be restricted towards the upper airway, encompassing the nose, neck, and windpipe. Earlier variations frequently resulted in lung scars and severe breathing problems.

When the Omicron variation was discovered in November, experts were concerned about the great amount of mutations and how they may affect patients. Earlier research suggested that some of the alterations could enable the virus to readily penetrate cells or evade antibodies, according to the source.

Over a dozen research organisations have been studying the Omicron version in the lab for the past month to see how it impacts the body. Despite the fact that COVID-19 instances have grown globally, hospitalizations have only marginally increased, and the variation seems to produce less severe illness than prior variants.

Omicron studies

Research on rodents affected by Omicron or previous coronavirus strains was issued last week by a consortium of Japanese and American experts. Animals infected with Omicron suffered reduced lung damage and died less frequently. Syrian hamsters, who had been critically sick with prior forms of the virus, exhibited fewer symptoms, according to the scientists.

“Overall, experiments from multiple independent laboratories of the SAVE/NIAID network with several different B.1.1.529 isolates demonstrate attenuated lung disease in rodents, which parallels preliminary human clinical data,” read the study.

Last week, 3 further papers were published, two focusing on Syrian hamsters, and one on mice. The Omicron variety causes less severe illness compared to the Delta form and other variants, according to the researchers. All four papers were released as preprints, which means they have not yet been reviewed by peers. More studies are currently being conducted
