What is known about the Covid 'Stratus' variant?
The 'Stratus' variant, also known as XFG and XFG.3, is a new strain of Covid that is spreading quickly in countries like the UK, US, and Southeast Asia. It belongs to the Omicron lineage and is characterized by mutations that may help it evade immunity. Experts note it causes mild symptoms, such as a hoarse voice, but its rapid spread is a concern.
-
How is the 'Stratus' variant spreading worldwide?
Since its first detection in Southeast Asia in January, 'Stratus' has spread to 38 countries by June. Its high transmissibility is driven by mutations that enhance its ability to infect people more easily, surpassing previous dominant strains like 'Nimbus'. The ongoing global movement and seasonal respiratory illnesses contribute to its rapid spread.
-
Should we be worried about immune evasion with new Covid strains?
Yes, immune evasion is a key concern with 'Stratus' due to mutations in its spike protein. These changes could reduce the effectiveness of existing vaccines and natural immunity, making reinfections more likely. Health authorities are closely monitoring these mutations to assess the impact on vaccine efficacy and public health strategies.
-
What are the latest vaccination updates related to Covid variants?
Vaccination efforts continue worldwide, with updates focusing on booster shots that target newer variants like 'Stratus'. Researchers are working on updated vaccines to improve protection against immune-evasive strains. Staying current with booster doses remains important to reduce the risk of severe illness.
-
Is 'Stratus' more dangerous than previous Covid variants?
Currently, WHO considers 'Stratus' a low-risk variant in terms of severity, as most cases are mild. However, its increased transmissibility and potential for immune escape mean it could lead to more infections, which might strain healthcare systems. Ongoing research is needed to fully understand its danger level.

What should I do to protect myself from new Covid variants?
The best protection includes staying up-to-date with vaccinations and booster shots, practicing good hygiene, wearing masks in crowded places, and maintaining social distancing where possible. Staying informed about local Covid trends and following public health advice is also crucial.
