COVID, flu, RSV: how these common viruses are tracking this winter – and how to protect yourself
Winter is here, and with it come higher rates of respiratory illnesses. If you've been struck down recently with a sore throat, runny nose and a cough, or perhaps even a fever, you're not alone. Last week, non-urgent surgeries were paused in several Queensland hospitals due to a surge of influenza and COVID cases filling up hospital beds. Meanwhile, more than 200 aged care facilities around Australia are reportedly facing COVID outbreaks. So, just how bad are respiratory infections this year, and which viruses are causing the biggest problems? COVID Until May, COVID case numbers were about half last year's level, but June's 32,348 notifications are closing the gap (compared with 45,634 in June 2024). That said, we know far fewer people test now than they did earlier in the pandemic, so these numbers are likely to be an underestimate. According to the latest Australian Respiratory Surveillance Report, Australia now appears to be emerging from a winter wave of COVID cases driven largely by the NB.1.8.1 subvariant, known as 'Nimbus'. Besides classic cold-like symptoms, this Omicron offshoot can reportedly cause particularly painful sore throats as well as gastrointestinal symptoms such as nausea and diarrhoea. While some people who catch COVID have no symptoms or just mild ones, for many people the virus can be serious. Older adults and those with chronic health issues remain at greatest risk of experiencing severe illness and dying from COVID. Some 138 aged care residents have died from COVID since the beginning of June. The COVID booster currently available is based on the JN.1 subvariant. Nimbus is a direct descendant of JN.1 – as is another subvariant in circulation, XFG or 'Stratus' – which means the vaccine should remain effective against current variants. Free boosters are available to most people annually, while those aged 75 and older are advised to get one every six months. Vaccination, as well as early treatment with antivirals, lowers the risk of severe illness and long COVID. People aged 70 and older, as well as younger people with certain risk factors, are eligible for antivirals if they test positive. Influenza The 2025 flu season has been unusually severe. From January to May, total case numbers were 30% higher than last year, increasing pressure on health systems. More recent case numbers seem to be trending lower than 2024, however we don't appear to have reached the peak yet. Flu symptoms are generally more severe than the common cold and may include high fever, chills, muscle aches, fatigue, sore throat and a runny or blocked nose. Most people recover in under a week, but the flu can be more severe (and even fatal) in groups including older people, young children and pregnant women. An annual vaccination is available for free to children aged 6 months to 4 years, pregnant women, those aged 65+, and other higher-risk groups. Queensland and Western Australia provide a free flu vaccine for all people aged 6 months and older, but in other states and territories, people not eligible for a free vaccine can pay (usually A$30 or less) to receive one. RSV The third significant respiratory virus, respiratory syncytial virus (RSV), only became a notifiable disease in 2021 (before this doctors didn't need to record infections, meaning data is sparse). Last year saw Australia's highest case numbers since RSV reporting began. By May, cases in 2025 were lower than 2024, but by June, they had caught up: 27,243 cases this June versus 26,596 in June 2024. However it looks as though we may have just passed the peak. RSV's symptoms are usually mild and cold-like, but it can cause serious illness such as bronchiolitis and pneumonia. Infants, older people, and people with chronic health conditions are among those at highest risk. In young children, RSV is a leading cause of hospitalisation. A free vaccine is now available for pregnant women, protecting infants for up to six months. A monoclonal antibody (different to a vaccine but also given as an injection) is also available for at-risk children up to age two, especially if their mothers didn't receive the RSV vaccine during pregnancy. For older adults, two RSV vaccines (Arexvy and Abrysvo) are available, with a single dose recommended for everyone aged 75+, those over 60 at higher risk due to medical conditions, and all Aboriginal and Torres Strait Islander people aged 60+. Unfortunately, these are not currently subsidised and cost about $300. Protection lasts at least three years. The common cold While viruses including COVID, RSV and influenza dominate headlines, we often overlook one of the most widespread – the common cold. The common cold can be caused by more than 200 different viruses – mainly rhinoviruses but also some coronaviruses, adenoviruses and enteroviruses. Typical symptoms include a runny or blocked nose, sore throat, coughing, sneezing, headache, tiredness and sometimes a mild fever. Children get about 6–8 colds per year while adults average 2–4, and symptoms usually resolve in a week. Most recover with rest, fluids, and possibly over-the-counter medications. Because so many different viruses cause the common cold, and because these constantly mutate, developing a vaccine has been extremely challenging. Researchers continue to explore solutions, but a universal cold vaccine remains elusive. How do I protect myself and others? The precautions we learned during the COVID pandemic remain valid. These are all airborne viruses which can be spread by coughing, sneezing and touching contaminated surfaces. Practise good hygiene, teach children proper cough etiquette, wear a high-quality mask if you're at high risk, and stay home to rest if unwell. You can now buy rapid antigen tests (called panel tests) that test for influenza (A or B), COVID and RSV. So, if you're unwell with a respiratory infection, consider testing yourself at home. While many winter lurgies can be trivial, this is not always the case. We can all do our bit to reduce the impact. This article is republished from The Conversation.

COVID-19 cases are on the rise in MA, CDC says. What to know about 'Nimbus' strain.
COVID-19 numbers are rising in Massachusetts, and in states across the country. "COVID-19 laboratory percent positivity is increasing nationally," according to the Centers for Disease Control and Prevention (CDC) website. "Emergency department visits for COVID-19 are increasing among young children 0-4 years old," though the CDC noted that emergency room visits are "low" overall. The latest COVID-19 strain is known as "Nimbus." Here's what to know. Are COVID-19 numbers increasing in Massachusetts? The CDC website has evaluated the issue in each state and determined cases in Massachusetts are likely rising. In Massachusetts, there is an 85.8% chance that COVID-19 numbers are increasing, according to the CDC. The Massachusetts Department of Public Health (DPH) reported that as of June 28, there were 377 confirmed cases of COVID and 77 unconfirmed cases. No COVID-19 deaths were reported at the time. The data stops in June because the Massachusetts DPH "ended data collection for the 2024-2025 viral respiratory season on June 28, 2025, and routine updates to their dashboard for the 2025-2026 season will resume later this summer." What is the current COVID-19 strain 'Nimbus?' As of early June, the new strain known as NB.1.8.1, or "Nimbus," made up 37% of COVID-19 cases nationwide. Variant NB.1.8.1 was first detected in China in January 2025 but accounted for about 0% of cases in the United States until May. The World Health Organization added at the time that currently approved COVID-19 vaccines are "expected to remain effective to this variant against symptomatic and severe disease." Virologists describe Nimbus as a 'slightly upgraded' version of its predecessor. While there is no evidence it causes more severe disease, it appears to be highly transmissible. What are the symptoms of Nimbus? Reported symptoms of NB.1.8.1 are similar to other COVID-19 strains, but one distinctive complaint is a severe sore throat, sometimes described as 'razor-blade throat fatigue.' Other symptoms may include: Mild cough Fever Muscle aches Nasal congestion Are vaccines still effective? Health experts say that updated COVID-19 vaccines remain the best protection against severe illness. Vaccination rates vary widely by state, and health officials continue to urge eligible individuals to stay current with their shots. How can people get tested? People can either take an at-home test or they can see their respective doctors. (This story was updated because an earlier version included an inaccuracy.)

A New COVID Variant Is Here, And It's More Transmissible — Here Are The Signs And Symptoms
A new COVID variant known as NB.1.8.1 has made landfall in the United States. As of late May, the variant, which was first detected in China this past January, accounted for 10% of the SARS-CoV-2 sequences tested from around the world, recent surveillance data found. That's a significant jump from 2.5% four weeks prior. A Centers for Disease Control and Prevention (CDC) spokesperson told HuffPost that the agency is in regular contact with international partners about the activity of NB.1.8.1. Up until late May, only 20 NB.1.8.1 sequences had been identified in the U.S. — that's below the threshold needed for a variant to appear on the agency's COVID dashboard. (As soon as its prevalence increases, NB.1.8.1 will pop up on the tracker, the spokesperson added.) It's nerve-wracking to hear that a new variant is making the rounds, but infectious disease specialists say there are no glaring differences between the symptoms of NB.1.8.1 and those caused by other versions of SARS-CoV-2. 'Currently it appears that NB.1.8.1 would have similar symptoms to other COVID variants that have recently been circulating,' Dr. Zachary Hoy, a pediatric infectious disease specialist with Pediatrix Medical Group in Nashville, Tennessee, told HuffPost. Here's what to know about the newest COVID variant that's gaining traction around the world. NB.1.8.1's mutations likely make it more transmissible. Compared to the currently dominant variant in the U.S. (LP.8.1), NB.1.8.1 has a handful of new mutations on the spike protein that may enhance its ability to bind to our cells, according to the World Health Organization (WHO). The agency suspects these mutations will increase the virus's transmissibility and, potentially, diminish the effectiveness of neutralizing antibodies that prevent pathogens from latching to our cells. In other words, the variant may be skilled at dodging some of our immune defenses, research suggests. Here are the signs and symptoms doctors are seeing with NB.1.8.1. According to Dr. Amesh Adalja, an infectious diseases expert and senior scholar at the Johns Hopkins University Center for Health Security, NB.1.8.1's symptoms are pretty much the same as those seen with other SARS-CoV-2 variants. Two of COVID's hallmark symptoms are a mild but persistent dry cough and nasal congestion, Hoy said. Many people who come down with COVID are also hit with fatigue and tiredness. 'An infected person can still make it through the day, but they are resting more and feel more tired throughout the day,' Hoy said. Other common symptoms include a fever, chills, a sore throat and muscle aches. 'Some have described recent variants as less intense symptoms as compared to wintertime influenza viruses, but both can have severe symptoms,' Hoy said. There's no evidence suggesting the variant causes more severe disease or an uptick in hospitalizations or deaths, the WHO states. The only noticeable aspect, as of now, is that it's rising in prevalence, Adalja said. How effective are the vaccines against NB.1.8.1? It's too early to know exactly how effective the shots are — as the research on NB.1.8.1 is limited since it's so new — but scientists expect the shots to hold up well. NB.1.8.1 broke off from the Omicron JN.1 lineage, which the 2024-2025 vaccines target. 'The ability of the vaccines to prevent severe illness is intact though protection versus infection is limited and transient,' Adalja said. Anyone who is at risk of severe disease should stay up-to-date with the shots. 'Those in older populations or with underlying immune disorders or on immune-decreasing medications would benefit more from vaccination or those with increased exposure such as healthcare workers,' Hoy added. So if you have a condition that puts you at risk, it's worth getting vaccinated if it's been more than six months since your last vaccine or bout of COVID, Adalja advises. He also added that those who are low-risk likely do not need to go out and get another shot. Know when to treat NB.1.8.1 at home and when to go visit a doctor. Most people will be able to recover at home by resting and staying hydrated. While you're sick, acetaminophen and ibuprofen can help alleviate muscle aches and fevers, Hoy said. And, in most cases, symptoms should clear up within a week. For those who are at risk for severe disease, including older adults and people who are immune-compromised, it's worth contacting a physician as they can prescribe antivirals — Paxlovid and Molnupiravir — that can significantly lower the risk of severe complications and death. As was the case with previous variants, these antivirals work best when started within five days of symptom onset. As for when you should go to an urgent care or emergency room? When you have chest pain, have a hard time waking up or staying awake, or feel confused and disoriented, the CDC advises. Hoy says the most concerning symptom he warns patients about is difficulty breathing. 'If you have COVID or COVID-like illness and have worsening trouble breathing or chest pain, you should be evaluated at your doctor's office, urgent care or the ER,' he said. Related...

Doctors issue urgent health warning as dangerous new Covid virus from China triggers US outbreak
A dangerous new Covid variant from China is surging in California, health officials warn. The California Department of Public Health warned this week the highly contagious NB.1.8.1 strain has been detected in the state, making it the sixth US state to be exposed. The variant has also been detected in international travelers arriving in Washington state, Virginia, Hawaii, Rhode Island and New York City since March. Health officials said the variant was first detected in March and has been on the rise since May 1. Since April, NB.1.8.1 has increased from two percent of Covid cases in California to 19 percent, according to health department data. Lab tests suggest NB.1.8.1, which was first detected in January in China, is more infectious than currently circulating strains, which means it could lead to a spike in infections and hospital admissions. World Health Organization data also suggests it makes up more than half the variants currently circulating. The warning comes as some physicians in California have called for the return of mask mandates to emulate countries like Hong Kong. The California Department of Public Health told The Sacremento Bee: ' COVID-19 continues to circulate in California and future seasonal increases in disease levels are likely.' NB.1.8.1 is not yet prevalent enough in the US to be publicly tracked by the CDC. Strain LP.8.1 is currently the most dominant in the US, making up 73 percent of Covid infections. The latest vaccines target the JN.1 variant, which LP.8.1 is descended from. The California Public Health Department said: 'Currently available vaccines are expected to remain effective.' However, health secretary Robert F Kennedy Jr has moved to remove access to the Covid vaccine for healthy children and pregnant women. However, it is currently still on the CDC's children's vaccine schedule. Covid tests in California as of April 19, the latest data available, show 2.1 percent of tests came back positive, a steady rate compared to weeks prior. The rate of hospitalizations from Covid during the week of April 19 in California was 1.3 per 100,000 people, a slight decrease from 1.6 per 100,000 the week before. There is usually a delay of several weeks for the most recent data, and infections can take several weeks to result in hospitalization. Nationally, Covid test positivity has decreased from 2.9 percent May 17 to 2.7 percent the week of May 24. Covid-related emergency department visits have also decreased 6.5 percent during that time frame. In China, data shows the proportion of severely ill respiratory patients with Covid has jumped from 3.3 to 6.3 percent over the last month. The proportion of Chinese ER patients testing positive for Covid had jumped from 7.5 to 16.2 percent. Officials in Taiwan are also reporting a surge in Covid emergency room admissions, with the number rising 78 percent in a week over the seven-days to May 3, according to the latest data available. And hospitalizations have risen to a 12-month high in Hong Kong, thought to be driven by the new variant. Symptoms of NB.1.8.1 are similar to other variants and include fever, chills, cough, shortness of breath, fatigue, muscle aches, headache, loss of taste or smell, sore throat, congestion, nausea, vomiting and diarrhea. Covid swabs cannot detect which variant you have.
