Rise in Cov cases with mild symptoms, outbreak nears plateau: Docs

Kolkata: The number of Covid patients with mild symptoms shot up in Kolkata over the last week, indicating that the outbreak is about to reach a plateau and taper off with a subsequent dip, say experts.
Several hospitals have already seen a drop in patients testing positive at their outpatient departments (OPD), while those testing positive now have very mild symptoms. Although very few of these patients were admitted, the rise in transmission would help to halt the spread, doctors said.
"Once half the city's population gets the infection, numbers will start dipping. We saw a spurt last week, while the numbers have started dipping over the last three to four days.
Most patients have very mild symptoms — low fever and cough — with a few getting respiratory tract infections that are manageable at home. The elderly with comorbidities continue to be admitted, but now their number should start dropping," said Manipal Hospital Dhakuria infectious diseases physician Sayan Chakrabarty.
Peerless Hospital has seen a drop in number of patients for the first time since June 1. The hospital tested 65 patients between June 1 and 15, of whom 35 were positive.

"While some, including kids, needed admission, most had mild symptoms and were treated at the OPD. The positivity rate was above 50% till Friday when just one tested positive. None tested positive on Saturday and Sunday," said Peerless chief microbiologist Bhaskar Narayan Chaudhury.
CMRI Hospital has nine patients admitted, down from an average of 14 till last week. The current strain is very transmissible but triggers mild symptoms that led to a quick spread, said CMRI pulmonology director Raja Dhar.
"Symptoms have been restricted to mild fever and cough for the vast majority, and they, of course, don't require admission. We have seen a proliferation of young patients with symptoms, which indicates that the spread has hastened and a plateau is imminent," added Dhar.
He added that the hospital admitted just two patients in last four days and plans to start reducing the number of isolation beds by next week from the current 14 to six if the trend persists.
Even though several patients are admitted at Fortis Hospital Anandapur, many more have been treated at the OPD and did not require admission, said Fortis pulmonologist Sushmita Roychowdhury. "Severe cases are still happening but have slid. Many more have mild symptoms now, which is an indication that we are finally heading towards a plateau," said Roychowdhury.
Manipal Hospitals have multiple patients across its four units, including four at Dhakuria.
"Barring a couple, the rest have severe lung or cardiac ailments or have hypertension and diabetes. They tested Covid positive on admission, but their symptoms are largely mild and manageable," added Chakrabarty.
While the Dhakuria unit now has 10 Covid beds, including five at the ICU, the Mukundapur unit has five isolation cabins, and the Salt Lake unit has another five. Medica has isolation cabins with separate entry and exit points. Sources said both Medica and Mukundapur have elderly patients with comorbidities who tested positive on admission.

Pneumonic plague claims life in the US: Symptoms, risks, and how it spreads
Pneumonic plague, the deadliest and most contagious form of plague, recently claimed a life in Northern Arizona—sending a shockwave. The victim was rushed to Flagstaff Medical Center on July 11 and died the same day, marking the county's first pneumonic plague death since 2007. It's caused by Yersinia pestis, the infamous plague bacterium. We tend to think of flea-borne bubonic plague, but pneumonic plague is different—it hits the lungs. You either inhale droplets from someone coughing it up, or you progress to it after bubonic or septicemic forms. Symptoms to note Symptoms show up fast—usually 1–4 days after exposure. They start with fever, chills, headaches, body aches, and weakness. But then things get serious: you'll develop a brutal pneumonia—think chest pains, rapid breathing, coughing up bloody or watery mucus. It's the only form of plague that can spread from person to person. Without antibiotics, pneumonic plague is almost always fatal—death can come within 24–48 hours. Pneumonic plague is extremely rare—only around seven U.S. cases pop up yearly, mostly in rural western states like Arizona, New Mexico, Colorado, and parts of the Pacific Northwest. Victims often include those in close contact with wildlife or fleas, including ranchers, hunters, or even pets. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 5 Books Warren Buffett Wants You to Read In 2025 Blinkist: Warren Buffett's Reading List Undo How do people catch the infection? You can catch pneumonic plague in a few pretty sneaky ways. The most direct is by breathing in droplets from someone who's already infected—like if they're coughing or sneezing near you. That's why it's the only type of plague that spreads from person to person. But it can also start after being infected with bubonic or septicemic plague, which usually comes from flea bites or handling sick animals. If you've been around dead rodents, wild animals, or even pets that roam in plague-prone areas, there's a small chance you could pick it up—especially if they're carrying fleas. People who live in rural areas or work with wildlife (like hunters, campers, or pet owners) are usually more at risk. The good news? It's super rare. But if you've been exposed and suddenly feel feverish or short of breath, don't wait—get checked out fast. Early treatment makes all the difference. Prevention tips Preventing pneumonic plague isn't complicated—it's mostly about avoiding fleas and sick animals, and acting fast if you've been exposed. If you're out hiking or live in a rural area, use bug spray with DEET and wear long pants tucked into socks to keep fleas away. Don't touch dead animals, and definitely don't let your pets sniff around carcasses or roam freely in plague-prone zones. Keep your pets on flea prevention year-round, especially in the western U.S. where cases pop up more often. If your cat or dog gets sick after being outside, take them to the vet and mention any wildlife contact. If you've been around someone coughing and you're feeling off—especially fever or chest pain—don't wait it out. Go see a doctor quickly. Pneumonic plague moves fast, but with early antibiotics, it's totally treatable. Basically, be smart around animals, avoid fleas, and don't ignore weird symptoms. The information provided in this article is for general awareness and educational purposes only. It is based on publicly available sources as of July 2025 and is not intended as medical advice. Pneumonic plague is a rare but serious condition—if you believe you've been exposed or are experiencing symptoms, consult a qualified healthcare professional immediately. While efforts have been made to ensure accuracy, medical data can evolve. Always rely on licensed medical providers for diagnosis, treatment, and prevention strategies.

It's time you knew about these 5 natural alternatives to retinol
(Image Credits: Pinterest) With the introduction of Korean products into the Indian market, it seems women have gone gaga over the launch of various serums, face masks, and toners - products the Indian skincare scene wasn't really familiar with before. Amidst this huge K-beauty wave came a formulation that sounded super promising for our skin but also brought along some side effects that didn't sit well with many. We are talking about retinol in skincare, which has been a game-changer for some but a total turnoff for others. Praised for its ability to tackle signs of ageing, acne, and uneven skin tone, retinol quickly became a staple in many girls' vanities. But despite its perks, it's not for everyone, especially if you have sensitive skin that can't handle its strength. What is Retinol ? Retinol is a vitamin A derivative that boosts cell turnover, stimulates collagen production, and unclogs pores. It's widely regarded as one of the most effective anti-ageing ingredients and is usually recommended starting in your early 30s. Valued for skin renewal and rejuvenation, retinol penetrates deep into the skin and interacts with receptors, influencing cellular processes. But if your skin is sensitive, it's best to avoid retinol, it's a potent formula that can either make or break your skin. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Mortgage Rates Drop Across the Board - Compare Rates Today for Savings NerdWallet Learn More Undo (Image Credits: Pinterest) No worries though, if you would rather skip retinol creams and serums, Mother Nature's got your back. Here are five natural alternatives to try that can give you noticeable results. Bakuchiol Derived from the seeds of the babchi plant, bakuchiol is the perfect natural swap for retinol. With the rise of clean skincare, bakuchiol has become a favorite because it works like retinol by boosting collagen and cell turnover but without causing irritation. It's gentle enough for sensitive skin and still packs a punch. Natural ingredients for glowing skin NovoRetin This water-soluble ingredient comes from the mastic tree and boosts the amount of naturally occurring retinoic acid in your skin, delivering retinol-like benefits. NovoRetin improves skin elasticity and density, reduces wrinkles and blemishes, and shrinks the look of pores. Plus, unlike retinol, it's stable and gentle, with no harsh aftereffects. Rosehip oil Made from pressed seeds and fruit of the rose plant, rosehip oil is loaded with antioxidants that support healthy skin. It's well-known for reducing hyperpigmentation and scars, calming irritation, and protecting against inflammation. It also contains fatty acids that build ceramides, helping deeply hydrate your skin and improve your complexion. (Image Credits: Pinterest) Carrot seed oil A rich source of vitamin A and antioxidants, carrot seed oil is a powerful natural option. It fights free radicals and environmental damage and serves as a great vegan alternative to retinol. You can easily add it to your skincare routine for a gentle yet effective boost. Rosemary extract Rosemary extract is another solid retinol alternative thanks to its strong antioxidant properties and skin-nourishing benefits. It acts as an anti-inflammatory and has antibacterial powers, soothing inflammation and calming acne-prone skin.
