'JN.1 Variant Not Fatal But...': Ex-AIIMS Chief Randeep Guleria On Rising Covid-19 Cases
Last Updated:
Dr Guleria said COVID-19 vaccines protect against the JN.1 variant, though not fully due to its mutations. They still lower the risk of severe illness, hospitalisation and death
Several countries, including India, are witnessing a fresh surge in COVID-19 cases, sparking renewed public concern. After a period of relative decline, infections are once again on the rise—driven by emerging variants.
Amid this uptick, Dr. Randeep Guleria, former director of AIIMS Delhi, has weighed in on the situation, offering insights and advice on how to stay safe. Speaking to a private news channel, Dr. Guleria explained that the increase in COVID-19 cases is primarily due to the JN.1 variant, first identified in August 2023.
This variant, a sub-variant of the Omicron lineage, is spreading rapidly due to mutations in the spike protein, enabling it to evade the immune system. Dr. Guleria shared that while the JN.1 variant is not highly fatal and generally causes mild symptoms such as fever, cough, sore throat, cold, and runny nose, it can be more dangerous for the elderly, individuals with comorbidities like diabetes or heart disease, and those with weakened immune systems. Dr. Guleria emphasised that these vulnerable groups should adhere strictly to COVID-19 protocols to avoid infection.
The situation in India remains under control, but ongoing surveillance of the new variant is necessary, he said adding that preparations should be made to handle any potential escalation.
The former AIIMS director said current data suggests that COVID-19 vaccines offer protection against the JN.1 variant, although they may not fully prevent infection due to its mutations. Vaccines help reduce the severity of the illness and the risk of hospitalisation or death. However, the constant mutations in the virus may decrease the effectiveness of older vaccines, he cautioned.
According to experts, people with serious health conditions should take extra precautions to avoid COVID-19. In addition to vaccines, various antiviral medications are now available, which can help treat COVID-19 and reduce the severity of symptoms, they said.
These drugs have proven effective against the virus and have contributed to lower mortality rates compared to the early stages of the pandemic, they said adding that antiviral medications are particularly beneficial for high-risk patients, aiding in their recovery.
Experts have advised that since COVID-19 symptoms often resemble those of other infections, anyone experiencing a cough, cold, or fever should consider getting tested.

Mamata Banerjee holds meet on COVID preparedness, says there is no reason to panic
Amid spike in COVID-19 cases, West Bengal Chief Minister Mamata Banerjee held a meeting on preparedness of the State on Monday (June 9, 2025). While stressing that there was nothing to panic about, the Chief Minister asked authorities to keep infrastructure updated to ensure immediate response in case of emergencies. West Bengal reported 747 active cases, among the highest in the country at the moment. Ms. Banerjee has taken note of the situation and asked officials to maintain vigilance. 'Whoever is responsible for handling this disease, including rural and urban healthcare workers, corporation, health department, police, we called everyone and did a COVID preparedness meeting,' Ms. Banerjee said. 'Do not cause panic, but we need to stay alert, in case there is any abnormal spike, we will stay prepared. People who have co-morbidities need to take more care and seek medical help,' Ms. Banerjee, who also heads the Health Ministry in the State, added. The Chief Minister also urged people to visit government hospitals to treat COVID-19 so that no one incurs extra expenses. She said that medical needs of affected persons will be taken care of at public health facilities. Similar sentiments were echoed by medical professionals from the State. Dr. Sujan Bardhan, Consultant (Tuberculosis & Chest Diseases), Narayana Hospital, RN Tagore Hospital Mukundapur, 'While the rise in COVID-19 cases in Bengal and the report of one death may cause concern, vigilance, not panic, is the best response. The key difference with these new strains is their speed, not their severity. Hospitals are well-prepared, and the healthcare system remains under no immediate strain. Nonetheless, the importance of basic preventive measures cannot be overstated.'

Measles cases surging globally. Should children be vaccinated earlier?
Sydney: Measles has been rising globally in recent years. There were an estimated 10.3 million cases worldwide in 2023, a 20 per cent increase from 2022. Outbreaks are being reported all over the world including in the United States, Europe and the Western Pacific region (which includes Australia ). For example, Vietnam has reportedly seen thousands of cases in 2024 and 2025. In Australia, 77 cases of measles have been recorded in the first five months of 2025, compared with 57 cases in all of 2024. Measles cases in Australia are almost all related to international travel. They occur in travellers returning from overseas, or are contracted locally after mixing with an infected traveller or their contacts. Measles most commonly affects children and is preventable with vaccination, given in Australia in two doses at 12 and 18 months old. But in light of current outbreaks globally, is there a case for reviewing the timing of measles vaccinations? Some measles basics Measles is caused by a virus belonging to the genus Morbillivirus. Symptoms include a fever, cough, runny nose and a rash. While it presents as a mild illness in most cases, measles can lead to severe disease requiring hospitalisation, and even death. Large outbreaks can overwhelm health systems. Measles can have serious health consequences, such as in the brain and the immune system, years after the infection. Measles spreads from person to person via small respiratory droplets that can remain suspended in the air for two hours. It's highly contagious - one person with measles can spread the infection to 12-18 people who aren't immune. Because measles is so infectious, the World Health Organization (WHO) recommends two-dose vaccination coverage above 95 per cent to stop the spread and achieve "herd immunity". Low and declining vaccine coverage, especially since the COVID pandemic, is driving global outbreaks. When are children vaccinated against measles? Newborn babies are generally protected against measles thanks to maternal antibodies. Maternal antibodies get passed from the mother to the baby via the placenta and in breast milk, and provide protection against infections including measles. The WHO advises everyone should receive two doses of measles vaccination. In places where there's a lot of measles circulating, children are generally recommended to have the first dose at around nine months old. This is because it's expected maternal antibodies would have declined significantly in most infants by that age, leaving them vulnerable to infection. If maternal measles antibodies are still present, the vaccine is less likely to produce an immune response. Research has also shown a measles vaccine given at less than 8.5 months of age can result in an antibody response which declines more quickly. This might be due to interference with maternal antibodies, but researchers are still trying to understand the reasons for this. A second dose of the vaccine is usually given 6-9 months later. A second dose is important because about 10-15 per cent of children don't develop antibodies after the first vaccine. In settings where measles transmission is under better control, a first dose is recommended at 12 months of age. Vaccination at 12 months compared with nine months is considered to generate a stronger, longer-lasting immune response. In Australia, children are routinely given the measles-mumps- rubella ( MMR ) vaccine at 12 months and the measles-mumps-rubella-varicella (MMRV, with "varicella" being chickenpox) vaccine at 18 months. Babies at higher risk of catching the disease can also be given an additional early dose. In Australia, this is recommended for infants as young as six months when there's an outbreak or if they're travelling overseas to a high-risk setting. A new study looking at measles antibodies in babies A recent review looked at measles antibody data from babies under nine months old living in low- and middle-income countries. The review combined the results from 20 studies, including more than 8,000 babies. The researchers found that while 81 per cent of newborns had maternal antibodies to measles, only 30 per cent of babies aged four months had maternal antibodies. This study suggests maternal antibodies to measles decline much earlier than previously thought. It raises the question of whether the first dose of measles vaccine is given too late to maximise infants' protection, especially when there's a lot of measles around. Should we bring the measles vaccine forward in Australia? All of the data in this study comes from low- and middle-income countries, and might not reflect the situation in Australia where we have much higher vaccine coverage for measles, and very few cases. Australia's coverage for two doses of the MMR vaccine at age two is above 92 per cent. Although this is lower than the optimal 95 per cent, the overall risk of measles surging in Australia is relatively low. Nonetheless, there may be a case for broadening the age at which an early extra dose of the measles vaccine can be given to children at higher risk. In New Zealand, infants as young as four months can receive a measles vaccine before travelling to an endemic country. But the current routine immunisation schedule in Australia is unlikely to change. Adding an extra dose to the schedule would be costly and logistically difficult. Lowering the age for the first dose may have some advantages in certain settings, and doesn't pose any safety concerns, but further evidence would be required to support this change. In particular, research is needed to ensure it wouldn't negatively affect the longer-term protection that vaccination offers from measles. Making sure you're protected In the meantime, ensuring high levels of measles vaccine coverage with two doses is a global priority. People born after 1966 are recommended to have two doses of measles vaccine. This is because those born before the mid-1960s likely caught measles as children (when the vaccine was not yet available) and would therefore have natural immunity. If you're unsure about your vaccination status, you can check this through the Australian Immunisation Register . If you don't have a documented record, ask your doctor for advice. Catch-up vaccination is available under the National Immunisation Programme . (The Conversation) PY PY

163 cases of newly emerging COVID-19 variant XFG detected in India: INSACOG
New Delhi: About 163 cases of the newly emerging COVID-19 variant XFG have been detected in India so far, according to INSACOG data. The recombinant XFG variant harbours four key spike mutations and has achieved rapid global spread following its initial detection in Canada, according to an article in The Lancet journal. According to data from the Indian SARS-CoV-2 Genomics Consortium (INSACOG), the XFG variant of the COVID-19-causing virus has been found in a total of 163 samples -- highest (89) in Maharashtra, followed by Tamil Nadu (16), Kerala (15), Gujarat (11), and Andhra Pradesh, Madhya Pradesh and West Bengal (six each). In May, as many as 159 samples were detected with XFG variant while two samples tested for this variant in April and two in June yet, data shows. India's active Covid case tally crossed the 6,000 mark, with 769 added in the last 48 hours, according to the Union health ministry data released on Sunday.
