What to know about the COVID variant that may cause 'razor blade' sore throats
The COVID-19 variant that may be driving a recent rise in cases in some parts of the world has earned a new nickname: "
razor blade throat
" COVID.
That's because the variant - NB.1.8.1.

or "Nimbus" - may cause painful sore throats. The symptom has been identified by doctors in the United Kingdom, India and elsewhere, according to media outlets in those countries.

of any variant include fever, chills, cough, shortness of breath or loss of taste or smell.
Experts say there isn't major cause for concern with the Nimbus variant, but here 's what else you need to know about it.
Here's where the variant causing 'razor blade throat' spreading The rise in cases late last month is primarily in eastern Mediterranean, Southeast Asia and western Pacific regions, the World Health Organization said May 28.
The new variant had reached nearly 11% of sequenced samples reported globally in mid-May.
Airport screening in the United States detected the new variant in travelers arriving from those regions to destinations in California, Washington state, Virginia and New York.
You aren't likely to get sicker from this variant than others Not so far, anyway.
The WHO said some western Pacific countries have reported increases in COVID cases and hospitalizations, but there's nothing so far to suggest that the disease associated with the new variant is more severe compared to other variants.
COVID-19 vaccines are effective against the Nimbus variant Yes.
The WHO has designated Nimbus as a "variant under monitoring" and considers the public health risk low at the global level. Current vaccines are expected to remain effective.
Health Secretary Robert F Kennedy Jr announced last month that COVID-19 shots are no longer recommended for healthy children and pregnant women - a move immediately questioned by public health experts.

XFG dominant strain, multiple Omicron subvariants spreading in Maharashtra, reveals genome study
Pune: Multiple emerging Covid-19 strains — all Omicron subvariants — were spreading across the state, Maharashtra's genome sequencing surveillance revealed. The latest sequencing data from 184 samples across 10 districts showed XFG as the currently dominant variant with 84 cases. It was followed by 38 unassigned variants, 34 LF.7.9 cases, 27 JN.1 cases and one NB.1.8.1 case detected in Pune. Nine samples from Mumbai were detected with the XFG subvariant, while three others with LF. 7.9. The NB.1.8.1, identified in a 29-year-old woman from Pune, showed high ACE2 affinity and immune evasion, hinting at the variant's potential to dominate future surges as per recent studies. ACE2 acts as a receptor for the spike protein of coronaviruses, allowing the virus to enter host cells. XFG, dominating in Maharashtra, and LF.7.9 are noted for their strong immune escape because of specific mutations, though their lower receptor-binding efficiency may require further adaptations. Dr Rajesh Karyakarte, Maharashtra's genome sequencing coordinator, BJ Medical College, told TOI, "After NB.1.8.1 was identified in Hong Kong as causing a surge in Covid cases, we at BJGMC, Pune, and NIV, Pune, parallelly started sequencing RT-PCR positive Covid-19 samples for the presence of this SARS-CoV-2 variant. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Esse novo alarme com câmera é quase gratuito em Eugenópolis (consulte o preço) Alarmes Undo CSIR-NCL, Pune's study also showed a spike in SARS-CoV-2 signals. Our findings after whole genome sequencing (WGS) revealed XFG to be the most dominant variant in the state, which wasn't a dominant global variant at that time around the world. We also identified LF.7.9 as another major variant in tested samples." Dr Karyakarte said, "The numbers confirm that XFG drove the current surge and not NB.1.8.1 (labelled Variant Under Monitoring [VUM] by WHO). After studying the sequences uploaded on WHO recommended GISAID database, it is clear that NB.1.8.1 is more common in Southeast Asia, while XFG prevails in India, Pakistan and Bangladesh — possibly because of immunity factors. Recently, XFG has also been rising in the US." Dr Ameet Dravid, infectious disease expert, Noble Hospital, said, "XFG is merely an Omicron sub-variant, similar to those in circulation during the third wave in 2022. Thanks to immunity built from previous infections, we're seeing very few severe cases this time. XFG is highly transmissible because of mutations that allow it to spread easily from person to person, leading to many upper respiratory tract infections. Its capacity to damage lungs or cause complications is minimal. So, patients with these symptoms are recovering well with outpatient treatment." Dr Dravid said, "Only a tiny fraction requires admission for pneumonia or ARDS (Acute Respiratory Distress Syndrome), the complications we saw in the first three waves. The damage has been limited despite low vaccination rates and waning vaccine-induced immunity over the last three years. We're relieved there hasn't been a significant surge in Covid admissions. While cases are increasing, most are mild, and improving with symptomatic care like nasal decongestants, cough suppressants and paracetamol for fever or body aches. " Hospitals in the city reported a noticeable uptick in Covid cases this week compared to previous weeks. Daily or alternate-day deaths, mostly among those with pre-existing conditions, have been recorded. The state health data indicated 31 fatalities since January this year — as many as 30 linked to comorbidities and one to another illness. Infectious disease specialists said this trend mirrored past surges. Individuals with underlying health issues remain vulnerable as infections rise. Dr Piyush Chaudhary, infectious disease specialist, Jehangir Hospital, said, "This variant (XFG) appears mild, but even mild strains can lead to some mortality, especially if the number of cases is high. The elderly or those with comorbidities may experience severe outcomes. We also haven't seen worsening severity — patients in ICU were there because of other medical conditions, not Covid itself. We must determine if Covid contributed to deaths or if underlying comorbidities were the primary cause. Currently, it seems, comorbidities, not Covid, are driving severe cases this season. Case numbers are definitely rising, though many with mild symptoms aren't testing. Among those tested, the positivity rate has increased proportionally."

What Is Aspergillus Fumigatus? Deadly Fungus Spreading In US That ‘Eats You From Inside Out'
Last Updated: Aspergillus Fumigatus is now being detected with increasing frequency in Florida, Louisiana, Texas, Georgia and California. Health experts are raising concerns over the rapid spread of a deadly airborne fungus, Aspergillus fumigatus, across parts of the United States. The pathogen, which causes a potentially fatal lung infection called aspergillosis, poses a heightened threat as rising temperatures create ideal conditions for its growth, experts warned. The fungus is now being detected with increasing frequency in Florida, Louisiana, Texas, Georgia and California- states where warm and humid environments allow it to thrive- Daily Mail reported. The World Health Organization labeled Aspergillus fumigatus a 'critical priority" pathogen, citing its growing resistance to treatment and high mortality rates. What Is Aspergillus Fumigatus And Its Symptoms? Once inhaled, the fungus can lead to serious respiratory infections, particularly in people with weakened immune systems or pre-existing lung conditions. Symptoms can escalate rapidly, potentially resulting in organ failure or death, especially among cancer patients, transplant recipients and those recovering from severe influenza. Individuals undergoing chemotherapy, long-term corticosteroid therapy or AIDS patients are considered especially vulnerable. The fungus is commonly found in soil, compost piles and damp environments, where it can survive temperatures as high as 120°F. The US Centers for Disease Control and Prevention (CDC) issued precautionary advice to reduce the risk of exposure to Aspergillus fumigatus. While these measures cannot guarantee full protection, they are recommended- especially for those with weakened immune systems or existing respiratory conditions, the health body said. The CDC advises people to avoid dusty areas such as construction sites. If exposure is unavoidable, wearing an N95 mask is recommended. During outdoor activities like gardening, individuals should wear long-sleeved clothing, full-length pants and closed-toe shoes and ideally avoid direct contact with soil or compost. In case of any cuts or abrasions, the area should be washed immediately with soap and water to reduce the risk of infection.

Raipur: Chhattisgarh has reported its first Covid death this year. An 86-year-old patient, who had multiple comorbidities and was on regular dialysis, died at a private hospital in Raipur on June 14, officials said on Monday. It's the first fatality in the state linked to the JN1 variant, said officials. Chhattisgarh has recorded 118 Covid-19 infections this year. There are 51 active cases, of whom 41 are in home isolation, nine are on oxygen support, and one patient is in ICU. According to health officials, the 86-year-old, a native of Rajnandgaon, had multiple comorbidities, including chronic renal failure, hypertension, and interstitial lung disease. His condition worsened, and he tested positive for Covid during routine screening. He died on the same day due to complications related to his health issues, said officials. On Monday, the state reported 10 new cases, including three each from Raipur and Bilaspur, two from Durg and 1 each from Mahasamund and Surguja. The daily growth rate of Covid-19 stands at 23.1%, while the recovery rate is twice that at 56.4%. Health experts predict that the state could see around 50 more cases in the next 10 days, but three patients on average are recovering each day. Health authorities said that they are on alert after the Covid death. The govt has begun training technical and non-technical healthcare staff in district hospitals and health centres in sample collection and patient treatment. Covid cases have been recorded in nine districts - including Raipur, Durg, Bilaspur, Bastar, Surguja, Mahasamund and Bemetara. Health department has urged people with cold and flu symptoms to get tested for Covid.
