Covid-19, the Stratus variant and its symptomsone in particular, the Raucendine. A new document widespread by the World Health Organization (WHO) speaks of it, according to which the variant officially called XFGwas designated as a variant of SARS-DONE-2 under monitoring (Vum), due to a global presence that “It’s growing quickly”. Although to date the additional risk to public health represented by Stratus is evaluated as bassowill circulate during this summer together with Rainstorm. Here is what variant it is and what the symptoms are.
The Stratus variant
Stratus and a variant of sars-cov-2 recombinant of the lignages LF.7 and LP.8.1.2 and its first sample collected dates back to January 27. Comparing JN1 with XFG and NB.1.8.1, or Rainstormthe Covid variant currently dominant, “It is possible to identify distinct changes in the Proteina Spike”, they explain from WHO. Among these, “Spike mutations to amino acids 478 and 487 improve the circumvention of antibodies”. In other words, therefore, it could be more skilled to evade ours immune system.
The diffusion of the variant
If in India the XFG variant was dominant throughout spring, while Nimbus has remained very rare, as of June 22, 2025, as they tell from the WHO, they were sent to Gisaid 1648 XFG sequences from 38 countries, which represent the 22,7% of the sequences available globally in the epidemiological week ranging from 26 May to 1 June 2025. “This is a significant increase in proportion compared to 7,4% recorded four weeks earlier ”, The experts remember, underlining that the percentage has increased in all three regions of WHO that constantly share Sars-Cov-2 sequences. In the European one, more in detail, its presence has increased from 10.6% to 16,7% for the European Region.
Covid-19, the variant Stratets
Although the data currently available do not show that the variant causes a more serious disease or deaths than others in circulation, among the symptoms There is one of Stratus that would seem to characterize it more. It is, as reported by Times of Indiafrom the hoarseness. In addition to the roca item, moreover, Covid patients have reported dry cough, irritation and sore throat, as well as the most common symptoms such as fever, muscle pain and tiredness.
Are vaccines effective?
“It is expected that i vaccines against Covid-19 currently approved remain effective Against this variant against symptomatic and serious disease “have specified by the WHO, which will continue to regularly evaluate the impact of the variants on the effectiveness of the vaccines against Covid-19 to guide decisions on updates of the composition of the vaccine. Considering the evolution of the global epidemiological situation and to support Member States in facing the continuous risk represented by Covid-19 during the transition from the response to an emergency of public health of international interest to his management As part of larger programs for disease prevention and control, “The permanent recommendations for Covid-19 issued by the general manager of WHO, whose validity was originally scheduled for April 30, 2025, were extended by a further year with the same content, up to April 30, 2026”conclude by WHO.
