New Nimbus COVID-19 Variant Could Trigger Summer Wave
A new COVID-19 variant called Nimbus, descended from Omicron, is spreading.
Scientists warn it could cause a surge in cases this summer.
Nimbus has already caused a surge in Southeast Asia.
Experts say immunity from previous infections or vaccines may be fading.
Warmer weather could also increase the spread.
Nimbus may infect cells more easily and evade the immune system.
Current vaccines are expected to work against it.
Symptoms are similar to other variants, but after-effects might last longer.
The WHO is monitoring Nimbus.
Scientists recommend vaccinations, including boosters, to protect vulnerable people.
A new COVID-19 variant, Nimbus, is circulating and spreading.
Nimbus is descended from Omicron and is highly contagious.
Cases are surging in Southeast Asia, with potential for a summer wave in the UK and Europe.
Experts believe waning immunity and warm weather could fuel the spread.
Current vaccines are expected to remain effective against Nimbus.
