The new COVID-19 variant Nimbus has been detected in Sweden, prompting health experts to monitor its impact.
Key Points
- • Nimbus (NB.1.8.1.) is a new COVID-19 variant first detected in Asia.
- • A limited number of cases have been reported in Sweden, raising concerns about increased transmission.
- • Nimbus is classified as a variant under monitoring by the WHO.
- • Health experts report that it may cause more gastrointestinal issues, but is not deemed more dangerous than previous variants.
A new COVID-19 variant, designated Nimbus (NB.1.8.1.), has been detected in Sweden, raising concerns about its characteristics and implications for public health. First identified in Asia, the variant has already seen a handful of reported cases within the country. Health experts are closely monitoring Nimbus, which is categorized by the World Health Organization (WHO) as a variant under monitoring (VUM).
Virology professor Niklas Arnberg from Umeå University stated that Nimbus, a subvariant of Omicron, may possess mutations that could evade some existing immunity from earlier variants. However, he emphasized that it is premature to conclude whether Nimbus represents a greater threat than its predecessors. Current reports indicate the variant might lead to increased gastrointestinal issues such as diarrhea, yet there is no substantial evidence suggesting that it is more severe compared to previous variants.
Epidemiologist Magnus Gisslén confirmed that the Swedish population possesses a substantial level of immunity against COVID-19, which should help mitigate the impact of new variants like Nimbus. He acknowledged a potential rise in COVID-19 cases during the upcoming summer and fall seasons and highlighted the importance of ongoing vigilance in monitoring both local and global trends regarding the variant.
As it stands, Nimbus may be contributing to heightened anxiety about the pandemic’s trajectory in Sweden, prompting public health officials to advocate for continued preparedness against any fluctuations in case numbers.
