New Covid-19 Variant Stratus Surges in Ireland Amid Early Symptoms

A new strain of Covid-19, known as the Stratus (XFG) variant, is rapidly spreading across Ireland, accounting for a significant proportion of recent infections. In the first week of September 2023, health authorities reported 425 new cases, with Stratus now responsible for 76.1 percent of all reported infections, a sharp increase from 49.3 percent just six weeks prior.

The Health Protection Surveillance Centre (HSPC) revealed that Dublin has been particularly affected, recording 89 new cases. Cork followed with 57 cases, and Limerick reported 33 cases. In contrast, some counties remain largely unaffected, with Laois and Mayo reporting no new infections and Roscommon logging only one.

The World Health Organisation (WHO) has classified Stratus as a “variant under monitoring,” indicating its faster transmission compared to other strains. Fortunately, preliminary data suggests it does not lead to more severe illness. Health officials have pointed out an unusual early symptom that may be overlooked: a hoarse or raspy voice. This symptom can appear before more common indicators such as fever or cough.

Dr Kaywaan Khan, a general practitioner based in Harley Street, emphasized the significance of this symptom, stating, “One of the most noticeable symptoms of the Stratus variant is hoarseness, which includes a scratchy or raspy voice.” Other symptoms linked to Stratus may include nasal congestion, sore throats, stomach upsets, and fatigue.

Dr Peter Chin-Hong from the University of California, San Francisco, noted that this new variant presents a broader range of symptoms than previous strains. He commented, “There’s a little bit more sore throats with some people, particularly in those who are older, who didn’t get vaccinated last year.” With children returning to school, he cautioned that a simple sniffle could potentially indicate Covid-19.

Long-Term Effects of Covid-19 on Health

In addition to the immediate symptoms associated with the Stratus variant, health experts are raising concerns about potential long-term effects of Covid-19. Recent research suggests that the virus may accelerate the ageing of blood vessels, raising the risk of heart disease, particularly among women.

A study published in the European Heart Journal, led by Professor Rosa Maria Bruno at the Université Paris Cité in France, indicates that Covid-19 could lead to blood vessels ageing approximately five years prematurely. Professor Bruno highlighted the importance of understanding these long-term consequences: “Since the pandemic, we have learned that many people who have had Covid are left with symptoms that can last for months or even years. However, we are still learning what’s happening in the body to create these symptoms.”

The study involved 2,390 participants, with an average age of 50, from 16 different countries between September 2020 and February 2022. Findings revealed that among women, a SARS-CoV-2 infection was associated with stiffer arteries, and this effect appeared to be more pronounced in women compared to men, as well as in individuals experiencing symptoms of long Covid.

Professor Bruno urged the need for early identification of those at risk to mitigate future cardiovascular complications, including heart attacks and strokes. As health officials continue to monitor the evolving situation regarding the Stratus variant, public awareness of both immediate symptoms and long-lasting effects remains crucial in managing the ongoing impact of Covid-19 in Ireland and beyond.
