A new variant of Covid-19, known as Nimbus (NB.1.8.1), is rapidly spreading worldwide and is closely monitored by the World Health Organisation. Recent data from the UK Health Security Agency shows a nearly 10% increase in Covid-related hospital admissions, with 947 patients admitted in the week leading up to May 31. Additionally, there has been a 6.9% rise in cases, with 1,211 reported in the week ending on June 4.

Dr. Naveed Asif, a GP at The London General Practice, has identified a distinct symptom associated with this variant - a severe sore throat described as a “razor blade sensation”. This symptom manifests as a sharp stabbing pain in the throat, particularly when swallowing. The recommended remedies include rest, fluids, and painkillers to alleviate the discomfort.

Dr. Mohamed Imran Lakhi mentioned that individuals infected with this variant commonly experience symptoms such as severe sore throat, persistent fatigue, mild cough, fever, muscle aches, nasal congestion, and sometimes digestive issues like nausea or diarrhea, which are not typically seen with other Covid variants.

The NHS advises individuals who suspect they have Covid to stay at home. Fortunately, the vaccines currently approved are effective against this new variant, according to a World Health Organisation spokesperson. Despite an increase in cases and hospitalizations in countries where NB.1.8.1 is prevalent, there is no indication that this variant causes more severe illness than other circulating variants.

Dr. Gayatri Amirthalingam, a deputy director at UKHSA, clarified that while the Nimbus variant has been detected in small numbers in the UK, international data suggests it is becoming more prevalent. However, there is no evidence to suggest that this variant leads to more severe disease or that current vaccines will be less effective against it.

If symptoms persist or worsen, individuals are advised to consult a GP or call 111 for assistance. In cases of serious distress, such as difficulty breathing, it is recommended to call 999 for immediate medical attention.
