Bird flu outbreak in US Nagar, over 5k chickens die
Rudrapur: Bird flu outbreak has led to the death of over 5,000 chickens across multiple farms in Kichha and Khatima in Udham Singh Nagar district of Uttarakhand on Wednesday. Authorities have enforced strict biosecurity measures to contain the spread of the highly contagious H1N1 avian influenza virus. However, at GB Pant University's poultry farm in Pantnagar, where over 2,000 chickens died between Aug 13 and 19, tests ruled out bird flu. Officials said the deaths may be linked to another poultry disease or environmental factors, which are still being investigated. "As a precaution, sale of chicken has been suspended and entry of visitors has been completely banned. The entire premises is being sanitised daily, along with lime sprinkling in and around the farm," said Dr Ripusudan Kumar, deputy director of the poultry farm. He added that all 22 employees have been provided with masks, protective suits and long boots. Meanwhile, poultry deaths in Kichha and Khatima have raised alarm. In Kichha alone, 2,222 chickens tested positive for bird flu, while in Khatima's Nadanna village of Chakarpur, over 1,000 birds perished at a private farm on Wednesday morning. Samples have been sent for further testing. District authorities have imposed strict containment measures. In Kichha's Kishanpur, a private poultry farm was sealed for three months after sanitisation. "After confirmation of bird flu, transportation of poultry within a 10 km radius has been strictly prohibited," said SDM Gaurav Pandey. "People are also advised to avoid consuming chicken and eggs for some days as a safety measure." The outbreak has also raised concerns in Bageshwar, where bird flu was earlier confirmed in one chicken after 77 samples from Soli village were sent to the laboratory in Bareilly. Alarmed by the spread, Almora district authorities have tightened biosecurity protocols at its zoo and rescue centres. "Tourists are allowed entry into Almora Zoo only after hand sanitisation. Staff members have been instructed to maintain strict hygiene, and maintaining distance is being ensured between visitors and wildlife," said Kishore Goswami, forest officer at Almora Mrig Vihar. Similar precautions have been enforced in Jim Corbett National Park. "Employees are strictly prohibited from entering rescue centres without safety kits. Staff handling tigers and leopards must wear PPE kits at all times," forest officials said. Stay updated with the latest local news from your city on Times of India (TOI).

Pune hospitals see rise in ‘long flu' cases
Several hospitals in the city have reported a sharp rise in cases of 'long flu', a condition where influenza-like symptoms such as cough, fever, cold, body aches and fatigue continue for over four weeks. The trend has been observed in both children and adults, said doctors. Normally, the flu symptoms subside within three to five days with proper medication and rest. However, doctors said from the past one month, there has been an increase in the number of patients experiencing prolonged illness, where cough, fatigue, and body ache linger far beyond the usual recovery period. (REPRESENTATIVE PHOTO) Normally, the flu symptoms subside within three to five days with proper medication and rest. However, doctors said from the past one month, there has been an increase in the number of patients experiencing prolonged illness, where cough, fatigue, and body ache linger far beyond the usual recovery period. Dr Ameet Dravid, infectious diseases expert, Noble Hospital, said most of the patients who are taking more than three to four weeks to recover are not infected with regular flu but with the H1N1 (Swine flu) and H3N2 subtype of the influenza A virus. 'The cases of patients infected with H3N2 are increasing and they take more recovery periods compared to seasonal flu and H1NI. The symptoms, like weakness and cough, last for over four weeks. This season, we have seen several patients with prolonged flu-like symptoms. However, only a few patients have undergone testing,' he said. Dr Prashant Udavant, paediatrician at Ruby Hall clinic, said, there is a surge in pediatric patients infected with flu and in a month, over 10 children have tested positive for H3N2. 'Daily, around 25 to 30 children come with flu infections. Most of them complain of high fever, dehydration, vomiting, cold, cough and fatigue. The respiratory symptoms are reported later in the second week of infection. The patients come with a history of the entire family being infected with influenza, one after the other,' he said. A parent of a child infected with long-flu-like symptoms said, 'My son initially had high fever, cold, cough, and dehydration. After three days, the fever and cold vanished, but his cough has persisted for four weeks now. Additionally, he has lost his appetite.' Dr Preeti Ajapuje, Infectious Disease expert at VishwaRaj Hospital, said that with the influenza virus, the patients generally recover in a week, but some of the symptoms, like weakness, may remain for a few weeks. Most of the time, the treatment is the conservative treatment for fever and pain relief as required. 'We generally advise exercises and lifestyle modification. The people in whom we see post-viral illnesses are the ones who have comorbidities like diabetes, hypertension, heart diseases, etc., and the age group of above 60,' she said.

Doctors warn of rising dual infections during monsoon
1 2 Pune: City doctors have warned patients contracting multiple infections simultaneously like typhoid, influenza and dengue this monsoon, leading to severe symptoms and increased complication risk, making management more challenging. Infectious disease experts said such "dual infections" were not uncommon at this time of year. Dr Mahesh Kumar Manohar Lakhe, infectious diseases expert with Sahyadri Hospitals, said, "I've seen cases of typhoid and dengue co-infection, confirmed through NS1 antigen and blood culture tests. In one instance, a traveller even had dengue and malaria together. These dual infections can be challenging, as both diseases can impact the liver, exacerbating the condition. " Dr Devashish Desai, consultant for infectious diseases at Ruby Hall Clinic, said dengue admissions were significantly lower this year compared to 2024, but the admitted patients were often in critical condition with severe dehydration and capillary leak. "Over the past three weeks, Pune has seen a surge in influenza cases, particularly the H3N2 strain of Influenza A. Many patients are presenting with symptoms like fever, sore throat, runny nose and cough. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Use an AI Writing Tool That Actually Understands Your Voice Grammarly Install Now Undo What's notable is that some patients are developing sequential or co-infections. Some are catching influenza right after recovering from dengue, or vice versa. I've seen dengue patients develop influenza-like symptoms just as they're about to be discharged, while others with persistent fever after influenza are later diagnosed with dengue. These co-infections are still relatively rare, about one case a week."

"This includes avoiding mosquito bites by using repellents, wearing full-sleeved clothing and eliminating stagnant water around homes. People should drink only boiled or filtered water to prevent typhoid, wash hands before eating and avoid street food during the monsoon," a specialist said. Dr Ameet Dravid, infectious diseases expert at Noble and Poona Hospitals, told TOI, "We have had an H1N1 and Covid-19 co-infection case this season. The patient, who presented with upper respiratory tract symptoms, was vaccinated against both influenza and Covid-19 and therefore experienced only a mild illness. In unvaccinated individuals, however, one of the viruses can dominate, potentially leading to viral pneumonia and a poorer prognosis.
