The real anti-nationals: Civil defence staff Vikas Kumar, Chiman Lal arrested for selling info to Pakistan

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.

An Indian resident who won the Dh20 million (approximately Rs 50 crore) jackpot in Abu Dhabi's Big Ticket draw has told of his joy at sharing his life-changing fortune with a friend.

Shanthanu Shettigar, a shop manager in Muscat, regularly buys tickets for the monthly grand prize draw with one of his closest friends – and the pair won on February 3.

Mr Shettigar, 33, who is from Udyavar in Udupi district of the southern state of Karnataka and has lived in the Omani capital for eight years, said he was left speechless after learning of his success.

“When I first moved to Muscat, many of my colleagues were purchasing Big Ticket, which encouraged me to give it a try,” he said.

“I started buying tickets on my own, and later began sharing tickets with a close friend. The ticket that brought me this win was one we purchased together.”

“Like most people, I receive a lot of spam calls, and I was fully absorbed in my work as well. I knew the live draw was taking place tonight, but I never imagined my name would be announced,” he said.

“When I realised it was real and that I had won, I was honestly speechless. It still hasn’t fully sunk in, but I’m extremely happy.”

Mr Shettigar is not sure how he will spend his share of the money, but encouraged others to take part.

“This win was completely unexpected, so I want to take some time to think things through before deciding what to do next,” he said.

“I would definitely encourage others to participate with Big Ticket, whether with family or friends – you never know when your moment might come.”

The Big Ticket was established in 1992 with an initial first prize of Dh1 million. It is one of the most popular monthly raffles in the UAE.

It has transformed the lives of many people across the Emirates and beyond.

Entry to the Big Ticket Millionaire is Dh500. Tickets can be bought online or at counters at Zayed International Airport and Al Ain Airport.
