‘Covid needs more surveillance than common cold, cough'
Covid-19 surge without increased hospitalisation or deaths. Currently the Dean of BioSciences and Health Research at the Trivedi School of Biosciences, Ashoka University, and head of the Koita Centre for Digital Health, he spoke with Kavita Bajeli-Datt about the evolution and surveillance of Covid. Excerpts:
India is again experiencing a surge in Covid-19 cases. How do you view the latest surge, coming after a brief pause?
Globally, there have been many such surges since the initial Omicron wave. These have all been with descendants of Omicron, and no new variant of concern has emerged. The risk to public health has been low due to the change in the virus and, more importantly, sufficient immunity to protect against severe disease. I expect this surge to follow the same pattern as the rise in infections, with little change in hospitalisations or deaths. So, we should ride this wave, too.
Do we need to start wearing masks, especially those living in Kerala, Maharashtra and Delhi, which are the top contributors?
It is always good to avoid infections, and wearing masks in crowded places with poor ventilation is always a good idea, especially for high-risk individuals, such as the elderly. Whichever place tests more seems to be the highest contributor.

Cough, Cold, Or Something Worse? Why You Shouldn't Ignore Monsoon Flu Symptoms
Last Updated: Monsoon offers a breeding ground for the spread of viruses and bacteria. What looks like a common cold or viral fever might actually indicate something deeper. As the monsoon clouds roll in and bring a welcome respite from the heat, there's another problem that creeps up alongside – one filled with the heightened risk of infections. While many of us dismiss the flu during the rainy months as just a product of the weather change, this approach can be dangerous. The monsoon season in India is a breeding ground for numerous infections, and flu is one of the most commonly misinterpreted illnesses. What starts as a mild cold or fever is often treated with over-the-counter remedies, including antibiotics, which can actually worsen the problem. The onset of monsoon is accompanied by high humidity and pathogens, all of which create the perfect storm for the spread of viruses and bacteria. People often confuse flu-like symptoms with a common cold or the seasonal bug. This delay in recognising the illness can lead to more severe complications. Dr. Mahua Das Gupta, Director of Medical Affairs (Infectious Diseases) at HaystackAnalytics, says, 'Infections caused by respiratory viruses such as Influenza A (H1N1), H3N2, SARS-CoV2 and RSV can be severe, especially for those with compromised immune systems or pre-existing conditions like asthma, diabetes, and heart disease." The Risk of Misdiagnosis: Self-Treatment and Antibiotic Resistance In the rush to feel better, many people opt for self-medication, often reaching for antibiotics at the first sign of fever or cold. Dr Gupta says, 'This overuse of antibiotics has contributed to a growing problem – antimicrobial resistance (AMR). The WHO identifies AMR as one of the top ten global health threats, with an estimated 5 million deaths annually attributed to drug-resistant infections." 'The overuse of antibiotics accelerates the development of antibiotic-resistant bacteria, making future infections more difficult to treat. More dangerously, the symptoms can escalate into complications like pneumonia or even organ failure, requiring hospitalizations that could have been avoided with earlier, more accurate diagnosis and appropriate treatment," adds Dr Gupta. Early Diagnostics: The Key to Preventing Serious Illnesses The good news is that early diagnostic tools can help prevent the flu from escalating into more severe conditions. Dr Gupta says, 'Advanced technologies, like Next-Generation Sequencing (NGS), enable clinicians to identify pathogens at the genomic level with speed and accuracy that surpass traditional methods. NGS can detect the specific virus or bacteria causing the infection, even those that are difficult to culture or detect, using older diagnostic methods." NGS can detect a wide range of pathogens in a single test, including bacterial, fungal, and viral agents responsible for respiratory infections, and even reveal the antimicrobial resistance profiles of these pathogens. With a turnaround time as quick as 24 hours, this technology empowers clinicians to initiate the most effective treatment without delay. How Genomics Can Help with Flu Diagnosis NGS-based diagnostic tests can help physicians move beyond broad-spectrum antibiotics and make data-driven treatment decisions. These tests provide a clear picture of which pathogens are involved, whether viral, bacterial, or fungal, allowing for targeted treatment. Dr Gupta explains, 'By providing a comprehensive pathogen profile, genomic tests also enable doctors to understand the exact nature of a patient's infection. Instead of relying on trial-and-error, doctors can make informed decisions about whether to prescribe antiviral medications, manage symptoms, or employ more aggressive treatments." A Call for Vigilance: The Role of Preventive Care As the monsoon season approaches, it's crucial to stay vigilant about flu and other infections. Flu-like symptoms during this time shouldn't be dismissed as just the weather. Early intervention with proper diagnostics can prevent complications, reduce unnecessary antibiotic use, and combat antimicrobial resistance. view comments Disclaimer: Comments reflect users' views, not News18's.

War against cancer: A victory in progress as death rates tumble with new drugs, screening and prevention
The chances of getting affected by cancer increase as people age. Since the 1990s, the age-adjusted death rate related to cancer has fallen considerably read more The fight against cancer has been yielding results slowly and steadily. Data on cancer's manifestations and treatment has painted a positive picture. Could that mean that the world is inching closer to a cure? While an answer to that remains uncertain, other factors, like death rates and advanced medical treatment, suggest that things are looking better than they were a decade ago. Here's how: Falling death rates The chances of getting affected by cancer increase as people age. Since the 1990s, the age-adjusted death rate related to cancer has fallen considerably. For example, in the US, where cancer is the second-most common cause of death, the age-adjusted death rate is now a third lower than in the 1990s. This trend is not exclusive to America, but is mimicked by other developed countries as well. A 2024 report by the Nation on the Status of Cancer shows that overall death rates from cancer declined steadily among both men and women from 2001 through 2022, even during the first two years of the Covid-19 pandemic. STORY CONTINUES BELOW THIS AD Childhood leukaemia survival rates go up The survival rate of childhood leukaemia has increased significantly in the past few years. Now, it has a five-year survival rate above 90 per cent. This has been made possible by advancements in treatment measures for Acute Lymphoblastic Leukaemia (ALL), which is the most common type that affects children. Better prevention One of the most overlooked success stories in the fight against cancer is prevention. For instance, smoking rates have dropped sharply in high-income countries, likely preventing over 3 million cancer deaths in the US alone since 1975. Yet smoking still accounts for one in five cancer deaths globally. This means that anti-tobacco efforts in low- and middle-income countries, where smoking remains widespread, have the potential to save millions more lives. Cheaper treatment Cancer treatment has gone easy on the pockets considerably. Curbing the spread of cervical cancer, the most common cancer among women, is a case in point. Cervical cancer is caused by the delayed side-effect of infection with the human papillomavirus (HPV). Now, the prevalence of the HPV vaccine and its administration to young girls across the world has brought down the chances of getting the bug at all. In the UK, for example, HPV vaccines have brought down the rates of cervical cancer among women in their 20s are down by 90 per cent.

India sends 300,000 Measles and Rubella vaccine doses to Bolivia amid outbreak
New Delhi: India on Thursday dispatched a consignment of 300,000 doses of Measles and Rubella vaccines, along with medical supplies, to Bolivia to help the country deal with a growing outbreak of the disease. "India dispatched a consignment of 300,000 doses of Measles & Rubella vaccines along with ancillary supplies to support Bolivia in managing the outbreak of the disease. India stands by its friends in the Global South," Ministry of External Affairs spokesperson Randhir Jaiswal said in a post on X. The shipment arrives at a crucial time as Bolivia has declared a National Health Emergency due to a resurgence of measles cases in several areas. So far, 60 confirmed cases have been reported, according to Xinhua. "After urgently convening the National Strategic Council for Health Emergencies, in response to the measles epidemic that the country is experiencing and the high risk of the disease spreading, we have decided to declare a National Health Emergency with the firm intention of protecting the health and lives of the Bolivian people," Bolivian President Luis Arce Catacora announced on social media, as quoted by Xinhua. The emergency move aims to stop the virus from spreading through mass vaccination efforts and a coordinated response involving local governments, regional bodies, and international organisations. According to Catacora, this step will improve the country's response capacity, activate emergency protocols, and ensure that vaccines are available, especially for children under five. He urged the public to cooperate with health authorities and ensure full immunisation. "Our duty is clear: to protect our children and the entire population from a threat that has already raised health alerts across the continent," he said. Bolivia's Health Minister Maria Renee Castro also expressed concern, stressing the severity of the situation and the risks faced by vulnerable groups. "It is essential that parents get their children vaccinated. The country has 500,000 doses, specifically for girls and boys," Castro said, according to Xinhua. She added that measles is a highly contagious viral illness that can cause serious complications, including pneumonia, encephalitis, or even death, particularly among children with malnutrition or weak immune systems. According to Xinhua, the recent rise in measles cases in Bolivia has been linked to falling vaccination rates, disruptions in healthcare during the COVID-19 pandemic, misinformation, and lack of continuity in prevention programmes. Prime Minister Narendra Modi met Bolivian President Luis Arce Catacora on the sidelines of the BRICS Summit in Rio de Janeiro, where the two leaders reviewed the progress of bilateral cooperation and explored new areas of partnership, especially in the field of critical minerals. According to the Ministry of External Affairs, "The two leaders reviewed bilateral cooperation and expressed satisfaction with the progress achieved." They also discussed collaboration in trade and commerce, Digital Public Infrastructure and UPI, health and pharmaceuticals, traditional medicine, small and medium industries, training, and capacity building. "Both leaders recognized the potential for enhanced collaboration in the critical minerals sector and developing sustainable and mutually beneficial partnerships in the field," the statement said. The MEA noted that both sides "expressed satisfaction over the ongoing development cooperation between the two countries, including through Quick Impact Projects and capacity-building initiatives under the ITEC scholarship programmes." Prime Minister Modi also conveyed India's support for the people of Bolivia following the deadly floods that affected La Paz and other regions earlier this year. "Prime Minister expressed solidarity with the people of Bolivia in the wake of the severe flooding that occurred in March-April 2025 in Laz Paz and several other parts of the country," the MEA said. He further congratulated Bolivia on joining the International Solar Alliance and extended greetings on the upcoming national milestone. "Prime Minister conveyed his warm greetings to the people and Government of Bolivia on the occasion of the country's bicentennial celebration, marking 200 years of independence on 6th August 2025," the statement added.
