Covid-19 cases rising again: Should you wear a mask again? Experts say yes
Remember when we all hoped Covid-19 would just disappear? The virus, however, is not done with us yet. If you've been wondering whether masks, vaccines, and precautions still matter in 2025, health experts believe they do.
A renewed push for caution follows a slow uptick in cases and concern over emerging Omicron sub-variants. According to doctors, ongoing monitoring and preparedness are crucial—even when active case numbers appear low.
India's Covid-19 case count rises to 4,302 amid variant concerns
As of 8.00 am on Wednesday, 4 June, India reported 4,302 active infections, with 276 new cases, according to the Ministry of Health and Family Welfare (MoHFW). While these figures seem modest compared to earlier waves, health authorities remain cautious, particularly in states such as Maharashtra, Karnataka, and Delhi, where acute respiratory infections are rising.
The ministry has urged states to increase testing, while hospitals are conducting mock drills to assess oxygen plant readiness in case of a sudden spike.
New Covid-19 guidelines issued by Indian states for 2025 variant surge
Health departments in several states have issued fresh advisories focussed on three areas:
Testing and surveillance: States have been asked to boost genome sequencing of influenza-like illness and severe acute respiratory infection cases.
Preparedness: Hospitals must ensure Intensive Care Unit (ICU) beds, ventilators, Personal Protective Equipment (PPE) kits, and oxygen supplies are in place.
Vaccination: Although there is no official booster campaign yet, people—especially the elderly and immunocompromised—are encouraged to stay vaccinated.
In Maharashtra, district health authorities have been asked to conduct oxygen plant drills, prepare for a rise in respiratory cases, and promote early testing awareness.
In Delhi, the All India Institute of Medical Sciences (AIIMS) has introduced guidelines requiring staff to wear masks, practise hand hygiene, and limit exposure to infected individuals. Chief Minister Rekha Gupta said, 'Covid patients are getting hospitalised in Delhi, but there is no need to worry. The Delhi government is alert and hospitals are prepared to deal with any eventuality.' The advisory instructed that all medical equipment—including ventilators, BiPAP machines, oxygen concentrators, and PSA units—must be fully functional.
In Karnataka, the health department has appealed to the public to remain calm, alert, and cooperative with health protocols.
In Odisha, Health Secretary Aswathy S has urged people not to panic and confirmed that all Covid patients are currently stable. She added that the state government is taking all necessary steps to manage the situation.
In Arunachal Pradesh, State Surveillance Officer Lobsang Jampa noted that the detected strain appears milder than earlier variants and urged residents to remain calm.
ICMR issues updated Covid-19 testing protocols and variant tracking alert
The Indian Council of Medical Research (ICMR) continues to support widespread testing and ethical biomedical research. It has updated testing protocols for private laboratories and issued guidelines for the safe collection and transportation of samples.
ICMR is also monitoring the public health impact of variants such as NB.1.8.1, JN.1, LF.7.9, and XFG, and emphasises the importance of data-driven policy decisions.
Experts advise mask-wearing in crowded spaces as new Covid variants emerge
As Covid-19 continues to evolve, experts are advising the public to remain vigilant and consider wearing masks in certain settings. Dr Soumya Swaminathan, former Chief Scientist at the World Health Organization (WHO) and Chairperson of the M S Swaminathan Research Foundation, said the virus is likely to persist and could surge every six to eight months. She stressed the need for continued adherence to public health protocols, including wearing masks in crowded spaces.
The WHO also recommends mask usage as part of a layered strategy to suppress transmission. Proper mask-wearing—covering the nose, mouth, and chin—is essential for effectiveness.
Dr Diksha Goyal, Senior Consultant – Internal Medicine at Marengo Asia Hospitals, Gurugram, said masks remain a 'low-cost, high-impact' tool to protect both individuals and communities. 'As the cases are rising, masks should be worn in crowded, enclosed, or poorly ventilated areas, regardless of local case numbers,' she said.
Booster vaccine advised in 2025 for vulnerable groups, say health officials
If you are elderly, immunocompromised, or have pre-existing conditions, then yes, absolutely. WHO and Indian health authorities both recommend staying updated with boosters as new variants emerge.
Covid-19 safety tips for 2025: Masks, hygiene and vaccination still key
According to Dr Goyal, simple measures still work:
Wear a well-fitted mask in crowded indoor settings
Wash your hands frequently
Stay updated on local health advisories
Avoid unnecessary exposure if you're unwell
Get vaccinated or boosted, if eligible
If you are pregnant, consult your doctor before getting vaccinated. According to new guidelines from US federal health officials, 'The vaccine is not recommended for pregnant women. The vaccine is not recommended for healthy children.'
Covid-19 may no longer dominate headlines, but it is far from over. With evolving variants and slow surges, staying informed and prepared continues to be vital.

Bee sting caused Karisma Kapoor's ex-husband Sunjay Kapur's death? Bees can at times trigger a heart attack, say experts
What happens to the body during a bee sting? Could swallowing a bee trigger a heart attack? First aid for a bee sting About Sunjay Kapur In a tragic and startling incident, Sunjay Kapur — the Indian automotive tycoon and Chairman of Sona Comstar — passed away in England during a polo match, reportedly after swallowing a bee. He was in his 50s. Kapur, also known as the former husband of Bollywood actress Karisma Kapoor , suffered a heart attack following the incident, according to business consultant Suhel Seth, who confirmed his demise to ANI. The cardiac arrest, which was reportedly caused by the bee sting , might have triggered a wave of curiosity, with over 2 lakh searches for "Sunjay Kapur" recorded in the past 14 hours on Google alarming detail is that a bee sting may have played a role in the cardiac event, raising an important question: Can swallowing a bee really cause a heart attack?According to a report by the University of Melbourne, bees have a venom sac and a barbed stinger that act as defence mechanisms when they feel threatened. Once a bee stings, it injects venom into the skin, often leaving behind the stinger. This venom is a potent mixture of proteins and molecules that can cause pain, swelling, itching, and irritation in most a single sting generally results in minor local effects, some individuals develop severe allergic reactions to the venom, leading to a condition known as anaphylaxis — a potentially life-threatening immune response. The report notes that it is not the venom alone but the body's allergic overreaction that typically causes serious complications like life-threatening issues and a bee might seem like an unlikely hazard, but experts say it's not unheard of, especially during outdoor summer activities. Dr. Bobbi Pritt, a microbiologist and pathologist at the Mayo Clinic in Rochester, explains that while most bugs are digested without issue, insects capable of stinging or biting, such as bees, wasps, and fire ants, pose significant risks if such insects could lead to internal stings, for example, in the throat, triggering allergic reactions that escalate quickly. For individuals with allergies, this can cause hives, facial and throat swelling, breathing difficulty, and even sudden cardiac arrest if not treated promptly. Dr. Pritt warns that in such cases, the absence of immediate intervention, like an epinephrine injection, can prove stings typically result in the bee leaving its stinger behind. The reports of the University of Melbourne advise removing the sting within 30 seconds to reduce venom exposure. The most effective method is to scrape it off using a firm edge, such as a credit card or a fingernail. Applying a cold pack may relieve pain and swelling for mild reactions. However, if stung near the throat or if symptoms such as dizziness, wheezing, or difficulty breathing occur, immediate medical attention is Kapur was married to Karisma Kapoor from 2003 until their divorce was finalised in 2016. The couple had two children together: Samaira, born in 2005, and Kiaan, born in 2011. He later married Priya Sachdev, who has had a brief stint in Bollywood. He is survived by his wife, Priya and their son Azarias.

India moves to conserve rare earths, seeks halt to exports to Japan
India has asked state-run miner IREL to suspend a 13-year-old agreement on rare earth exports to Japan and to safeguard supplies for domestic needs, two sources familiar with the matter told Reuters, aiming to reduce India's dependence on China. IREL also wants to develop India's capacity for rare earth processing, which is dominated globally by China and has become a weapon in escalating trade wars. China has curbed its rare earth materials exports since April, pressuring automakers and high-tech manufacturers worldwide. In a recent meeting with auto and other industry executives, Indian Commerce Minister Piyush Goyal asked IREL to stop its exports of rare earths, mainly neodymium, a key material used in magnets for electric vehicle motors, one of the sources said. The Commerce Ministry, IREL and the Department of Atomic Energy, which oversees IREL, did not immediately respond to requests for comment. The sources declined to be identified because of the sensitivity of the matter. Under a 2012 government agreement, IREL supplies rare earths to Toyotsu Rare Earths India, a unit of Japanese trading house Toyota Tsusho, which processes them for export to Japan where they are used to make magnets. In 2024, Toyotsu shipped more than 1,000 metric tons of rare earth materials to Japan, commercially available customs data showed. That is one-third of the 2,900 tons mined by IREL, although Japan relies mainly on China for its rare earths supply. Toyota Tsusho and Toyotsu did not immediately respond to requests for comment. IREL has been exporting rare earths due to a lack of domestic processing capacity, but following the recent disruptions to supplies of Chinese material it wants to keep its rare earths at home and expand domestic mining and processing, a second source said, adding that IREL is awaiting statutory clearances at four mines. However, India may not immediately be able to stop supplies to Japan because they fall under a bilateral government agreement, the person said. IREL wants this to be "amicably decided and negotiated because Japan is a friendly nation", the person added. Japan's Trade Ministry said in a statement to Reuters: "We would like to refrain from answering questions about bilateral exchanges in general, not just about this matter." Expansion plans China's recent export controls on rare earth materials have rocked the global auto industry, which has warned of supply chain disruptions and production halts. China also weaponised its supplies in 2010, when it briefly stopped shipments to Japan. That prompted the Japanese to turn to India for rare earths. India has the world's fifth-largest rare earth reserves, at 6.9 million metric tons, but there is no domestic magnet production. India relies on imported magnets, mainly from China. In the fiscal year to March 2025, India imported 53,748 metric tons of rare earth magnets, government data showed. These are used in automobiles, wind turbines, medical devices and other manufactured goods. Rare earth mining is restricted to IREL, which supplies India's Atomic Energy Department with materials for nuclear power projects and defence-related applications. India lacks wide-scale technology and infrastructure to mine rare earths, and the development of any commercially viable domestic supply chain is years away, analysts said. IREL has a rare earths extraction plant in the eastern Indian state of Odisha and a refining unit in Kerala, in southern India. The miner, founded in 1950, plans to produce 450 metric tonnes of extracted neodymium in the fiscal year to March 2026 with a plan to double that by 2030, the second person said. It is also looking for a corporate partner for the production of rare earth magnets for the auto and pharmaceutical industries, the person said. India is firming up plans for incentives to companies to set up rare earth processing and magnet production facilities to meet local demand, people familiar with the matter told Reuters earlier this month.
