Ind vs Aus, Boxing Day Test: Leader Rahane hits winning runs as visitors level series 1-1

Bengaluru: Following reports of fresh Nipah virus (NiV) cases in West Bengal and heightened vigilance across parts of Southeast Asia, the Karnataka Health Department has placed the state on high alert and activated emergency preparedness protocols.

Health officials said enhanced surveillance measures have been initiated after two healthcare workers in Barasat, West Bengal, tested positive for the virus earlier this month. While no cases have been reported in Karnataka so far, authorities said the state’s past exposure to Nipah outbreaks and high inter-state mobility warranted preventive action.

Officials have directed district health teams to intensify monitoring, particularly at hospitals and points of entry, and to ensure early detection and isolation of suspected cases.

High Mortality Virus with Multiple Transmission Routes

Nipah virus is a zoonotic disease that can spread from animals to humans and has a reported fatality rate ranging between 60 and 75 per cent. Fruit bats, also known as flying foxes, are the natural reservoirs of the virus and can transmit it by contaminating food sources with saliva or urine.

Known modes of transmission include:

•    Contaminated food: Consumption of fruits partially eaten by bats or raw date-palm sap
•    Animal contact: Exposure to infected pigs or other animals
•    Human-to-human transmission: Close contact with body fluids of infected persons, particularly in healthcare settings

Symptoms and Disease Progression

The incubation period typically ranges from 4 to 14 days, though delayed onset has also been reported. Early symptoms often resemble common viral infections, making prompt clinical suspicion critical.

•    Initial symptoms: Fever, headache, body aches, fatigue, sore throat
•    Progressive symptoms: Drowsiness, disorientation, altered mental state
•    Severe stage: Seizures, neck stiffness and acute encephalitis, which can rapidly progress to coma

Public Health Advisory

The Health Department has issued precautionary guidelines urging the public to adopt risk-avoidance practices to prevent any local spillover.

Do’s
•    Wash fruits thoroughly before consumption
•    Drink boiled and cooled water
•    Use protective equipment while handling livestock
•    Maintain strict hand hygiene

Don’ts
•    Avoid fruits found on the ground or showing bite marks
•    Do not consume beverages made from raw tree sap, including toddy
•    Avoid areas with dense bat populations
•    Do not handle sick or dead animals

Preparedness Measures

Officials confirmed that isolation wards are being readied in major government hospitals and that medical staff are being sensitised to identify early warning signs.

“There is no cause for panic, but there is a need for heightened vigilance,” a senior health official said, adding that there is currently no approved vaccine or specific antiviral treatment for Nipah, and care remains largely supportive.

A fresh cache of files related to the investigation into the late convicted sex offender Jeffrey Epstein contains documents that reference President Donald Trump and other high-profile figures including Microsoft co-founder Bill Gates, Commerce Secretary Howard Lutnick and British billionaire Richard Branson.

Here are key details about mentions of the celebrities, none of whom have been accused of wrongdoing:

Donald Trump

The files included an FBI-compiled list of sexual assault allegations related to President Donald Trump -- many of them involving anonymous callers and unverified tips.

The allegations -- some secondhand -- were sent to the FBI's National Threat Operations Center which receives information by phone and electronically.

The document suggests that investigators followed up on a number of the tips. Some were deemed to lack credibility.

Trump has long denied any wrongdoing related to Epstein.

In a statement accompanying Friday's file dump, the Justice Department said: "Some of the documents contain untrue and sensationalist claims against President Trump that were submitted to the FBI right before the 2020 election. To be clear, the claims are unfounded and false."

Bill Gates

In a draft email among the documents, Epstein alleged Gates had engaged in extramarital affairs.

In the mail, Epstein wrote that his relationship with Gates had ranged from "helping Bill to get drugs, in order to deal with consequences of sex with russian girls, to facilitating his illicit trysts, with married women."

Richard Branson

Files show friendly relations between the two billionaires.

In an email sent to Epstein on Sept 11, 2013, Branson wrote "It was really nice seeing you yesterday. The boys in Watersports can't stop speaking about it! Any time you're in the area would love to see you. As long as you bring your harem!"

Elon Musk

The files contain numerous mail exchanges between Epstein and billionaire entrepreneur Elon Musk.

In November 2012, Epstein sent Musk an email asking "how many people will you be for the heli to island."

"Probably just Talulah and me. What day/night will be the wildest party on your island?" Musk replied.

Andrew Mountbatten-Windsor

The disgraced former prince invited Epstein to visit him at Buckingham Palace in September 2010 while the financier was making a trip to London.

An email exchange shows Epstein contacting Andrew to ask: "What time would you like me... we will also need... private time."

Andrew replied: "we could have dinner at Buckingham Palace and lots of privacy."

Howard Lutnick

Emails show that Epstein and businessman Lutnick -- currently Trump's commerce secretary -- made plans in December 2012 to lunch on Epstein's Caribbean island.

"We are heading towards you from St. Thomas" Lutnick's wife wrote to Epstein's secretary, asking where they should anchor.

Steve Tisch

Several mails suggested Epstein connected Steve Tisch, 76, producer of the movies "Forrest Gump" and "Risky Business" and the co-owner of the New York Giants football team, with multiple women.

In one exchange with Tisch, Epstein describes a woman as "russian, and rarely tells the full truth, but fun."

Zohran Mamdani's Mother, Filmmaker Mira Nair 

New York City Mayor Zohran Mamdani's mother, Mira Nair, attended an afterparty at convicted sex trafficker Ghislaine Maxwell's house for her 2009 film "Amelia", reveals a new set of Epstein files.

An email dated October 21, 2009, sent by publicist Peggy Siegal to Jeffrey Epstein, also surfaced in documents. The email, sent in the early hours, right after Siegal left the gathering, gives an insight into the afterparty. 

The party was also attended by former President Bill Clinton and Amazon CEO Jeff Bezos.

"Just left Ghislaine's townhouse...after party for film. Bill Clinton and Jeff Bezos were there...Jean Pigoni, director Mira Nair....etc," the email read.

The email described the reaction of guests to Nair's film as "tepid."

"Film received tepid reaction although women like it much more...Hillary Swank and Gen: at stupid party in Bloomingdales cheap sportwear department....very weird. Studio went for free party from store and windows for a month....Going to be in Wall Street 2 tomorrow ....more to come. xoxo Peg," the email read.

Bengaluru: As air quality continues to worsen across several parts of the city, hospitals in Bengaluru are reporting a steady rise in patients suffering from respiratory illnesses such as asthma, bronchitis and Chronic Obstructive Pulmonary Disease (COPD), health officials and doctors said.

Data from the Suvarna Arogya Suraksha Trust (SAST) shows that 3,891 patients received treatment for respiratory ailments between April and November 2024. The figure rose to 4,187 during the same period in 2025.

Private hospitals, too, are witnessing a 10–15 per cent year-on-year increase in such cases.

While doctors caution that the rise cannot be attributed solely to air pollution, a significant number of patients are non-smokers with no prior history of respiratory disease.

“Nearly 70 per cent of the patients we see are non-smokers with no previous respiratory issues. When other causes are ruled out, air pollution emerges as the most likely factor,” said Dr Manjunath PH, consultant interventional pulmonologist at a hospital in Kengeri.

Doctors noted that patient footfall spikes during the winter months and around Deepavali, when air quality typically worsens.

“There is a clear correlation between poor air quality and the rise in cases. People commonly present with persistent cough, breathlessness and irritation of the respiratory tract, indicating the impact of polluted air on their health,” said Dr Sheetal Chaurasia, consultant in pulmonary medicine at a private hospital in Whitefield.

Dr Chaurasia added that respiratory tract infections are also on the rise.

“Poor air quality leads to chronic airway inflammation, making the airways more vulnerable to infections. We are seeing an increase in both upper and lower respiratory tract infections,” she said.

Patients with pre-existing respiratory conditions remain the worst affected.

“For those already diagnosed with respiratory illnesses, deteriorating air quality significantly worsens the condition. Both the frequency and severity of attacks increase sharply,” said Dr Vandana P, a pulmonologist at a hospital on Bannerghatta Road.

Doctors also flagged a worrying trend of rising respiratory problems among younger adults and children.

To reduce exposure, they advised people to wear masks while travelling on two-wheelers or autos and ensure adequate ventilation at home to minimise indoor air pollution.
