A new COVID variant, NB.1.8.1, linked to a major surge in China, has been detected in the United States. The virus is believed to have arrived via international travelers, according to airport screenings and state reports.Experts are concerned, but the United States is currently experiencing low overall case numbers. It has been detected in several states, and while it is not yet widespread, it may become more contagious.Authorities say it's too early to panic, but they recommend taking precautions as new vaccines targeting related strains are being developed.Records submitted by the CDC's airport testing partner Ginkgo Bioworks show that cases associated with the NB.1.8.1 variant have been reported in arriving international travellers at airports in California, Washington state, Virginia, and the New York City area, as quoted in a report by CBS News.Information regarding the sequencing results, which were made public on the Global Initiative on Sharing All Influenza Data, or GISAID, virus database in recent weeks, indicates that travelers from a variety of nations, including China, Taiwan, Japan, South Korea, France, Thailand, the Netherlands, Spain, and Vietnam, are responsible for the cases.The variant, which is currently prevalent in China and is becoming more prevalent in other parts of Asia, has been the subject of intense scrutiny from experts.A CDC spokesperson said in a statement, "CDC is in regular contact with international partners and is aware of reported cases of COVID-19 NB.1.8.1 in China."The agency's variant estimates dashboard does not currently include enough reported U.S. sequences of NB.1.8.1.As the number of cases has increased, Hong Kong officials have begun to advise residents to wear masks in crowded areas and on public transit, despite their claims that there is no evidence that the variant, which is a descendant of the virus's XDV lineage, is more serious.Taiwanese health officials have also noted an increase in ER visits, serious illnesses, and fatalities. In reaction to the outbreak, local health officials say they are accumulating vaccines and antiviral medications.Americans are urged not to panic but remain vigilant and alert. With the number of cases remaining low nationally, health officials recommend reverting to simple precautions, particularly in crowded or confined areas. Wearing masks while using public transportation or during travel is an easy step to take to minimize risk.The need to update COVID-19 vaccines for the upcoming fall and winter seasons was discussed by outside vaccine advisers to the Food and Drug Administration.Last season's vaccines targeted a JN.1 descendant known as KP.2. According to preliminary data provided by Pfizer and Moderna, switching to a different JN.1 descendant known as LP.8.1 may increase protection against NB.1.8.1.Despite disagreements over specifics, the committee unanimously supported the recommendation that vaccines for the upcoming season target some form of JN.1 variant.While some advocated for the update to focus on the LP.8.1 descendant of JN.1 that Pfizer and Moderna have prototyped, others supported letting vaccine manufacturers continue using the vaccines from the previous season.Yes, it has been detected in travelers and reported in several states, including California, Ohio, and New York.Not yet, the variant isn't more severe, but it may spread more easily. Stay informed and consider vaccine options this autumn.

35-year-old man with comorbidities dies ten days after testing positive for COVID-19
VILLUPURAM: A 35-year-old man passed away ten days after testing positive for COVID-19 at the Villupuram government medical college hospital on June 6. The deceased, identified as Thiagarajan, a native of Perapperi village near Tindivanam, had been working as a construction contractor in Hyderabad. He allegedly contracted the virus while at work in Hyderabad ten days ago. Following the onset of fever and other COVID-related symptoms, he returned to his native village in Tindivanam, a week ago. Initially admitted to the Tindivanam government hospital, Thiagarajan was later referred to the Villupuram government medical college hospital for advanced treatment after his condition worsened early on June 6. Despite intensive medical efforts, he passed away due to cardiac failure, medical sources said. The deceased was diabetic, suffered from hypertension, cardiac issues and was under medication for Tuberculosis. Further, sources stated that his health deteriorated rapidly after his return from Hyderabad, leading to his eventual demise. Speaking to TNIE, Villupuram Deputy Director Health Services Dr Senthil Kumar said, "The patient tested positive for COVID in Hyderabad. However, he tested negative on Friday morning, but he died due to comorbidities. Six members who were in contact with him were isolated. People in the village have been asked to follow COVID-19 safety guidelines."

New coronavirus in China shows pandemic-like threat, scientists warn
A group of mysterious bat viruses might be just one tiny mutation away from becoming a serious problem for humans, warn US researchers in a new study published in the peer-reviewed journal Nature viruses belong to the same family as MERS-CoV, a dangerous coronavirus that emerged in 2012 and causes severe respiratory a death rate of around 34%, MERS-CoV has already shown the world what these viruses are capable Now, scientists from Washington State University, Caltech, and the University of North Carolina have turned their focus to a lesser-known subgroup called these, one subgroup in particular, called the HKU5 viruses, is raising red flags."HKU5 viruses haven't been studied much, but our research shows they have the machinery to infect cells. In fact, they might be only a single step away from being able to infect humans,' said Dr. Michael Letko, a virologist and lead author of the IS THIS WORRYING?Like the SARS-CoV-2 virus that causes Covid-19, these bat viruses use a spike protein to latch onto cells and infect them. With a death rate of around 34%, MERS-CoV has already shown the world what these viruses are capable of. () advertisementThis study showed that HKU5 viruses can bind to a receptor called ACE2, the same one used by Covid-19, but currently only in bats, not that line is thinner than it just a small genetic tweak, these viruses could potentially start binding to human cells. In fact, some versions have already been spotted infecting minks in China, a sign that they can jump across if that mutation happens in just the right way, the next big spillover could be on the horizon."These viruses are very close relatives of MERS. That alone should make us pay attention," Letko said in a take the research a step further, scientists also used AI, specifically a tool called AlphaFold 3, to simulate how the spike protein would interact with ACE2 receptors. This study showed that HKU5 viruses can bind to a receptor called ACE2, the same one used by Covid-19, but currently only in bats, not humans.() This software predicted virus behaviour in minutes, a process that would usually take months of lab work. The AI's findings closely matched results from traditional lab researchers had earlier shared findings of the new bat coronavirus, HKU5-CoV-2 in study led by virologist Shi Zhengli, who is also known as the 'batwoman".Zhengli found that in lab experiments, HKU5-CoV-2 infected human cells with high ACE2 levels in test tubes and in models of human intestines and researchers also identified monoclonal antibodies and antiviral drugs that target the bat DOES THIS STUDY MATTER?The study's findings matter because, as we've learned from Covid-19, viruses don't need a passport to go global. If we ignore the warning signs, we risk another pandemic blindsiding an eye on viruses like HKU5 gives scientists a head start in developing vaccines, treatments, and public health strategies, before it's too Dr. Letko put it, there's no need to panic, but there is every reason to prepare.

NB.1.8.1 Covid-19 variant makes up 10% cases globally: Should you worry?
Just when many believed Covid-19 was in the rear-view mirror, a new variant has quietly gained ground. NB.1.8.1, first detected in China in January 2025, now accounts for one in ten Covid-19 cases globally—up from just one in forty a month ago. It has spread across twenty-two countries so far. What is NB.1.8.1 variant? According to the World Health Organization, NB.1.8.1 is among several fast-evolving Omicron-lineage variants. From January to May 2025, global dominance shifted from XEC to LP.8.1, with NB.1.8.1 now surging rapidly. The WHO has classified NB.1.8.1 as a Variant Under Monitoring due to its rise in prevalence and potential public health implications. Officials stress that while vigilance is crucial, there is no cause for alarm. Vaccination remains the best protection against severe illness and death. How NB.1.8.1 behaves and how severe it really is NB.1.8.1 is a sublineage of the Omicron JN.1 family. It carries similar characteristics—high transmissibility, but mostly mild to moderate illness. It also includes new mutations on the spike protein, which may enhance its ability to spread and evade immunity. So far, there is no evidence to suggest NB.1.8.1 causes more severe disease, hospitalisations or death compared to previous variants. NB.1.8.1 symptoms: What to watch for Common symptoms include: Dry, persistent cough Runny or blocked nose Fatigue and general body aches Sore throat Fever or chills Headache or hoarseness in some cases Many report being able to go about daily activities but feel unusually tired and sluggish. Are vaccines still effective against NB.1.8.1? Updated vaccines, including the latest Omicron-targeted boosters, are designed to protect against the JN.1 family. While they may not prevent all infections, they continue to reduce the risk of hospitalisation and severe outcomes. Expert guidance includes: If you are over sixty, have chronic health conditions or are immunocompromised, get a booster if it has been more than six months since your last dose If you are healthy and under sixty, no new dose is required at present Use masks in public transport and crowded indoor spaces How to manage NB.1.8.1 symptoms at home In most cases, NB.1.8.1 does not require hospitalisation. Here is what helps: Rest and stay well hydrated Use paracetamol or other over-the-counter medications for fever or aches Recovery generally takes five to seven days If you are elderly or immunocompromised, speak to your doctor early. Antiviral medication is most effective within five days of the onset of symptoms. Warning signs: When to seek emergency help Seek urgent medical care if you experience any of the following: Difficulty breathing Chest pain or tightness Confusion or trouble staying awake Severe dizziness or fainting Do not panic, but stay informed Experts believe NB.1.8.1 will follow a familiar seasonal pattern seen with earlier variants—periodic surges during winter and summer months. Most infections remain mild. Vaccines continue to work. Keep an eye on symptoms, isolate if unwell, and consult your doctor when in doubt.
