Feeling Hoarse? You Might Have the New ‘Stratus' Covid Variant
Jul 2, 2025 5:00 AM The World Health Organization has added the variant, known formally as XFG, to its monitoring list. A dry, irritated throat is among its main symptoms. Photograph: loops7/Getty Images Another NEW covid variant is currently rapidly gaining a foothold. Known officially as XFG—or informally as 'Stratus'—it has been declared a 'variant under monitoring' by the World Health Organization (WHO), and is expected to circulate alongside the now dominant Nimbus variant throughout the northern hemisphere summer. The risk to public health is low, the WHO has said. Infections are characterized by a particular symptom: hoarseness. Stratus is a combination of the LF.7 and LP.8.1.2 lineages of the virus, and when comparing Stratus to the previously dominant JN1 variant, 'distinct mutational profiles in the spike protein can be identified,' the WHO has said. 'Spike mutations at amino acids 478 and 487 enhance antibody avoidance'—meaning, in other words, the variant may be more adept at evading our immune defenses. Stratus has been dominant in India throughout the spring, and has now started to spread at large across the world. Gisaid, a global initiative that tracks the spread of viral variants, reported that 22.7 percent of Covid samples submitted to it during the last week of May were Stratus, up from 7.4 percent four weeks earlier. These samples came from 38 different countries. Available data doesn't suggest that the variant causes more severe disease or deaths than others in circulation, though doctors in India have noted that hoarseness is a common symptom. Patients have also reported suffering a dry cough and sore throat, in addition to the more common Covid symptoms such as fever, muscle aches, and fatigue. 'The currently approved Covid-19 vaccines are expected to remain effective against this variant against symptomatic and severe disease,' the WHO stated in its risk assessment. The organization will continue to regularly assess the impact of this and other variants on the efficacy of vaccines, to guide decisions on vaccine updates.

A new COVID variant is spreading in the US: What are the symptoms?
A new COVID-19 variant that was unheard of just months ago is now projected to be the second-most common strain in the U.S. Variant NB.1.8.1 was first detected in China in January but accounted for about 0% of cases in the U.S. until May. By early June, it was estimated to account for up to 37%, according to the U.S. Centers for Disease Control (CDC). The World Health Organization (WHO) evaluated the additional public health risk posed by the variant as "low at the global level in a May report, in which it also advised that currently approved COVID-19 vaccines are "expected to remain effective to this variant against symptomatic and severe disease." Here's what we know about NB.1.8.1. NB.1.8.1 is one of the latest variants of COVID-19, a "slightly upgraded version" of the LP.8.1 variant that is prominent right now, Subhash Verma, microbiology and immunology professor at the University of Nevada, Reno, previously told USA TODAY in May. The new variant was first detected in January in China. As of mid-May, the variant had reached 10.7% of global reported COVID-19 cases, according to the World Health Organization (WHO). Verma previously said NB.1.8.1 may be able to be transferred more easily than LP.8.1. Additionally, he said that NB.1.8.1 is able to evade antibodies created by vaccines or past infections more easily than LP.8.1. "NB.1.8.1 is likely to spread more rapidly and evade our immune defenses more easily than LP.8.1, which is why this variant requires careful monitoring," Verma said. For a two-week period starting on May 25 and ending on June 7, the CDC's Nowcast estimates tracker shows projections for the different COVID-19 variants. According to the latest CDC data, the NB.1.8.1 strain is projected to be the second highest in the U.S., making up 37% of the total cases recorded in the U.S. The most common strain is LP.8.1, also known as Omicron, which accounts for 38% of cases, followed by NB.1.8.1 with 37%, XFG with 8%, XFC making up 7%, and LF.7.9 with 4%. The prominence of NB.1.8.1 in the U.S. has significantly increased in recent weeks, accounting for 0% of cases through March before reaching 2% in April, 5% in early May and 15% by late May. The CDC has not outlined symptoms that are specific to the NB.1.8.1. variant. Verma said that NB.1.8.1 symptoms appear similar to those of earlier COVID-19 variants. However, an extremely sore throat, colloquially called "razor blade throat," has been associated with the new variant. People with the variant have reported a feeling akin to their throats being covered with razor blades, according to the Los Angeles Times, Fox News, SF Gate, and other news outlets. Many people have also taken to social media to describe the "razor blade throat." The CDC outlines the following as common COVID-19 symptoms: The CDC advises seeking medical care if you experience any of the following symptoms: The World Health Organization states that currently approved COVID-19 vaccines are expected to remain effective against the NB.1.8.1 variant. In a webpage dated Jan. 7, 2025, the CDC advises that everyone over the age of six months get the 2024-2025 COVID-19 vaccine, specifically the 2024-2025 Moderna COVID-19 Vaccine. It also suggests that people who have never received a COVID-19 vaccine, are age 65 and older, are immunocompromised, live at a long-term care facility, are pregnant, breastfeeding, trying to get pregnant, and/or want to avoid getting long COVID, should get the vaccine, especially. However, Health and Human Services Secretary Robert F. Kennedy Jr. said on May 27 that the COVID-19 vaccine would no longer be included in the CDC's recommended immunization schedule for healthy children and pregnant women, a move that broke with previous expert guidance and bypassed the normal scientific review process. Under the changes, the only people who will be recommended for COVID-19 vaccines are those over 65 and people with existing health problems. This could make it harder for others who want the COVID-19 vaccine to get it, including health care workers and healthy people under 65 with a vulnerable family member or those who want to reduce their short-term risk of infection. This could mean that some who still wish to receive the vaccine may have to pay out of pocket, if they are able to access it at all. It is not yet known how accessible the COVID-19 vaccine will be moving forward. Increasing Community Access to Testing, Treatment and Response (ICATT), a federal program, continues to provide free COVID-19 testing to individuals without health insurance.

Symptom that hits '3 times in 24 hours' could signal Covid
The latest figures also highlighted two of the most dominant Covid variants at the moment People should stay vigilant for signs of COVID-19 as there's been a marginal uptick in cases across the UK. Government data reveals that in the week up to June 15, there has been an increase in the number of confirmed Covid infections in England. This included people in hospital who were given PCR tests. Hospital admissions due to coronavirus also increased slightly compared to the previous week. The predominant strains circulating during that time were identified as LP. 8.1.1 and XFG, each contributing to 19.87 per cent of the reported cases. Also present was the "Nimbus" strain or NB.1.8.1, representing 3.97 per cent of infections. LP. 8.1.1 evolved from LP. 8.1 which itself is a descendant of Omicron, with the original LP.8.1 having surfaced in July 2024 and later categorised as a "variant under monitoring" by WHO in January. Symptoms Currently, it remains uncertain whether LP. 8.1.1 triggers specific symptoms distinctive from other strains. Thomas Jeffries, a senior microbiology lecturer at Western Sydney University, observed that LP.8.1 does not seem to be responsible for exceptionally severe symptoms. Writing for The Conversation, he said: "Notably, the symptoms of LP.8.1 don't appear to be any more severe than other circulating strains. And the WHO has evaluated the additional public health risk LP.8.1 poses at a global level to be low. "What's more, LP.8.1 remains a variant under monitoring, rather than a variant of interest or a variant of concern. In other words, these changes to the virus with LP.8.1 are small, and not likely to make a big difference to the trajectory of the pandemic." However, according to the NHS, one definitive symptom of Covid is a new or persistent cough, which may involve three or more "coughing episodes" in 24 hours. Other indicators on the list are: A high temperature or shivering (chills) – a high temperature means you feel hot to touch on your chest or back (you do not need to measure your temperature) A loss or change to your sense of smell or taste Shortness of breath Feeling tired or exhausted An aching body A headache A sore throat A blocked or runny nose Loss of appetite Diarrhoea Feeling sick or being sick. The NHS guidance for those with symptoms of Covid suggests self-isolation until recovery. For those who receive a positive Covid test result, the NHS advocates staying home and away from others for five days, although it's not legally required. Further analysis of recent Covid statistics reveals that the weekly mean positivity rate for PCR tests in English hospitals was up slightly at 6.6 per cent for the week leading up to June 15, compared to 6.2 per cent in the prior week. The total weekly hospital admission rate for COVID-19 saw a slight rise to 1.53 per 100,000 from the previous week's 1.44 per 100,000. However, the overall rate of COVID-19 patients in ICU or HDU remained steady at 0.04 per 100,000, mirroring the previous week's figure.
