What do we know about the new Covid strain 'Stratus'?
The XFG 'Stratus' variant is spreading globally, with mutations that may help it evade immunity. It was first detected in Southeast Asia and has since been reported in multiple countries. While some mutations could make it more transmissible or resistant to vaccines, the WHO currently considers it a low global risk. Experts are monitoring its spread closely to understand its impact better.

How is antimicrobial resistance spreading?
Antimicrobial resistance, especially from bacteria with the NDM gene, is increasing sharply worldwide. In the US, cases have risen by over 460% since 2019, largely due to antibiotic misuse during the pandemic. These resistant bacteria are spreading in communities and hospitals, making infections harder to treat and posing a serious public health threat.
-
Are vaccines effective against new Covid variants like 'Stratus'?
Current vaccines still provide protection against severe illness from new variants like 'Stratus,' but their effectiveness against infection may be reduced. Booster shots and updated vaccines are being developed to improve immunity. Staying up-to-date with vaccinations remains one of the best ways to protect yourself and others.

What can people do to protect themselves this winter?
To stay safe this winter, get vaccinated and booster shots, practice good hygiene like handwashing, wear masks in crowded places, and avoid close contact with sick individuals. Staying informed about local Covid trends and antibiotic use can also help reduce your risk of infection and resistance.
-
Is antimicrobial resistance a global problem?
Yes, antimicrobial resistance is a worldwide issue, especially in regions like South Asia, Europe, and Latin America. The spread of resistant bacteria threatens to make many infections untreatable, increasing hospital stays and mortality rates. Efforts to reduce antibiotic misuse and improve infection control are crucial to tackling this crisis.

Will Covid variants like 'Stratus' cause more severe illness?
While some variants may spread more easily, there is currently no clear evidence that 'Stratus' causes more severe illness than previous strains. However, increased transmissibility can lead to higher case numbers, which can strain healthcare systems. Vaccination and preventive measures remain key to reducing severe outcomes.
