Overlapping symptoms make Cov diagnosis difficult without tests
Kolkata: The overriding symptoms of Covid during the current surge were a low-grade, persistent fever, along with a mild cough, which could be deceptive, warned doctors. While it made a vast majority ignore the symptoms and take over-the-counter medicines, for some, the fever refused to subside.
It was the continuing fever that led many to consult physicians.
Most of those testing Covid positive on admission to hospitals for other ailments were also screened at hospitals due to their fever.
Covid cases have been rising in Bengal over the past week. The state logged 319 cases in the past seven days, taking the number of active cases to 331 on Monday.
Unlike the first three waves, when Covid came with loss of smell and taste, accompanied by high fever, severe cough and pneumonia, the symptoms of the current spike were muted and flu-like, said doctors.
With a runny nose and a sore throat, symptoms in most were milder than that during the pandemic, said CMRI pulmonology director Raja Dhar. "Mild symptoms led many to ignore it, which could be risky at a time, when cases are proliferating.
One should get tested, and if the result turns positive, the patient should isolate, especially if there are elders in the family. Screening should be stricter for elderly people with comorbidities, and if the fever and cough persist beyond four to five days, hospitalization is advised as symptoms could worsen quickly," said Dhar.

CMRI has seven Covid patients admitted.
Manipal Hospitals infectious diseases physician Sayan Chakrabarty agreed. "The symptoms are flu-like, but for some, the fever persists. Those patients are getting tested, and many tested positive. While severe cases have been rare so far, rising numbers could lead to a spurt," he added. Five Covid patients, admitted to Manipal's different units, have been discharged.
Covid pneumonia has been rare this time, said Charnock Hospital pulmonologist Soumya Sengupta.
"Most patients have a cough and low fever. Even the elders in hospital who tested positive have muted Covid symptoms. Most are being treated for their comorbidities. During the pandemic, a vast majority of senior citizens had severe Covid symptoms, including pneumonia," said Sengupta.
Dhar pointed out that the Jn.1 variant of the Omicron, now believed to be in circulation, was highly transmissible though less virulent. "But it is safe to isolate yourself for five days on testing positive and take symptomatic drugs. Symptoms are likely to remain mild till this wave blows over in about a fortnight. But even mild Covid may aggravate comorbidities, especially those related to lungs," he said.

India will not talk to Pakistan with gun pointed at our head: Shashi Tharoor
US correspondent from US: An Indian parliamentary team tasked with highlighting Pakistan's terrorist depredations has conveyed to US interlocutors that New Delhi will not talk to Islamabad "with a gun pointed to our head" even as a Pakistani delegation tailing the Indian team in Washington DC desperately sought President Trump's mediation between the two sides. Summing up India's stance, delegation leader Shashi Tharoor likened Pakistan to a neighbor who "unleashes a rottweiler to bite your children and do worse and then says 'let's talk." Talks are not possible unless Pakistan locks up the rottweilers (terrorists) or puts them to sleep, Tharoor said. Tharoor also rejected efforts to insinuate US into bilateral issues saying India has enormous respect for the American presidency and the American president, but "we have never particularly wanted to ask anyone to mediate." India can speak all the languages Pakistan speaks and is happy to talk to them in any of them if they roll up their terrorism policy and infrastructure, "but as long as they use the language of terrorism, we will use the language of force. That doesn't require a third party,' Tharoor said, even as the team from Islamabad, in its meetings, rolled out the familiar trope of "Pakistan is a victim of terrorism," which the Indian delegation ridiculed. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo In one vivid presentation, BJP MP Tejasvi Surya listed five Pakistanis and five Indians who are famous in the US to highlight the difference between the two countries. For Pakistan: Ramzi Yousuf, Khalid Shaikh Mohammed, Faisal Shahzad, Tashfeen Malik, and Muhammad Shahzeb Khan -- all of whom conducted terrorist attacks on the US. For India: Indra Nooyi, Satya Nadella, Sundar Pichai, Ajay Banga, Arvind Krishna -- all corporate titans who have generated billions in economic activity in the US. "India gives tech titans, Pak gives terrorists," Surya noted. The Indian delegation met US vice-president JD Vance on Thursday morning to convey India's stand after engaging dozens of US lawmakers from the Senate Foreign Relations Committee and the India Caucus, which has nearly 200 legislators, including 40 Senators, compared to the Pakistan Caucus, which has only around 50 members -- a differential the Indian side mentioned to highlight the breadth of support for India. The Pakistani team meanwhile labored to make an impression on the few meetings its cobbled together on the Hill, insisting that the Kashmir issue was an 'unfinished agenda of the United Nations' despite being outed repeatedly on UN resolutions that seek Pakistan's withdrawal from the territory it has occupied. "Raised concerns over India's recent provocations, the deepening humanitarian crisis in Indian Illegally Occupied Jammu & Kashmir," Bhutto posted on X after one such meeting, even though there is no humanitarian crisis in J&K other than terrorist attacks initiated by Pakistan. The Indian delegation in fact told US interlocutors that J&K was seeing unprecedented economic activity and travel boom, "with more tourists than in Aspen, Colorado" before Pahalgam terrorist attack.

Want lower blood pressure and stronger legs? Japanese walking might be the simple daily fix you need
Could a simple change in your walking style be the key to improved health? A growing number of physicians and researchers believe so. " Japanese walking ," a method developed nearly two decades ago, is now being praised for its numerous benefits, including lower blood pressure , increased muscle strength , and better mental health. What is Japanese Walking? " Interval walking training ," which is currently referred to as "Japanese walking, a straightforward regimen that alternates between slow and fast walking, was created by Japanese researchers almost 20 years ago. How can you practice Japanese Walking?

For a total of 30 minutes each session, repeat the cycle, as per a report by Very Well Health. Why are three minutes required for the intervals? Researchers used three-minute intervals in the original study because older participants started to feel fatigued after that. Live Events If you couldn't initially handle three-minute intervals, you would probably still see some improvement with shorter ones. Starting with three minutes of regular walking, followed by one minute of brisk walking, and extending the duration of the brisk walking interval as your fitness increases would be entirely reasonable. Who benefits the most from this Japanese walking method? The most suitable individuals for Japanese walking are those who feel bored or stuck with your daily walking schedule. People who are striving to reverse insulin resistance, early metabolic syndrome, or have mild joint issues can benefit from this. This low-impact exercise is ideal for older adults or beginners because it is simple to start, requires no equipment, and may provide long-term cardiovascular and metabolic benefits. Children's National Hospital physical therapist Kevin McGuinness said, "This is a useful strategy for people who can't tolerate activities like running or hiking due to injury, weakness, or balance issues." ALSO READ: Jon Stewart's savage necklace joke goes viral as Karoline Leavitt reportedly ditches the bling in response What are the health benefits of Japanese walking? Anahita Kalianivala, PhD, a clinical psychologist in Reno, Nevada, believes that strategies such as interval walking can be surprisingly effective in re-training the nervous system to tolerate exercise. She explains that a common technique for managing chronic pain in cognitive behavioral therapy is time-based activity pacing, which helps the body and brain associate activity with safety and the ability to continue rather than danger and the need to crash, as quoted in a report. The exercise has been demonstrated to increase VO2max, decrease blood pressure, and aid in blood sugar regulation. Interval walking was found to increase peak aerobic capacity, thigh muscle strength, and blood pressure. Is Japanese walking easier and better than regular walking? • Interval walking is an effective way to improve long-term health, particularly for middle-aged and older adults. • It consists of alternating short periods of brisk walking and slower-paced recovery, which dynamically engages the cardiovascular system. • Interval walking is simple to learn, requires no special equipment or gym access, and causes metabolic changes. Can shorter intervals still help? If you would like to try Japanese walking, you could ease yourself into the routine by beginning with shorter bursts of brisk walking than the three-minute intervals used in it. FAQs Is Japanese walking better than regular walking? Yes, alternating speeds gives your heart and muscles a better workout while reducing strain. Can I practice Japanese walking if I am out of shape? You can begin with shorter intervals and progress gradually.
