Two MIT students including a foreigner drown

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.

Karnataka Governor Thaawarchand Gehlot read only three lines from the 122-paragraph address prepared by the Congress-led state government while addressing the joint session of the Legislature on Thursday, effectively bypassing large sections critical of the BJP-led Union government.

The omitted portions of the customary Governor’s address outlined what the state government described as a “suppressive situation in economic and policy matters” under India’s federal framework. The speech also sharply criticised the Centre’s move to replace the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) with the Viksit Bharat–Guarantee for Rozgar and Ajeevika Mission (Gramin) Act, commonly referred to as the VB-GRAM (G) Act.

Governor Gehlot had earlier conveyed his objection to several paragraphs that were explicitly critical of the Union government. On Thursday, he confined himself to the opening lines — “I extend a warm welcome to all of you to the joint session of the State legislature. I am extremely pleased to address this august House” — before jumping directly to the concluding sentence of the final paragraph.

He ended the address by reading the last line of paragraph 122: “Overall, my government is firmly committed to doubling the pace of the State’s economic, social and physical development. Jai Hind — Jai Karnataka.”

According to the prepared speech, the Karnataka government demanded the scrapping of the VB-GRAM (G) Act, describing it as “contractor-centric” and detrimental to rural livelihoods, and called for the full restoration of MGNREGA. The state government argued that the new law undermines decentralisation, weakens labour protections, and centralises decision-making in violation of constitutional norms.

Key points from the unread sections of the speech:

•    Karnataka facing a “suppressive” economic and policy environment within the federal system

•    Repeal of MGNREGA described as a blow to rural livelihoods

•    VB-GRAM (G) Act accused of protecting corporate and contractor interests

•    New law alleged to weaken decentralised governance

•    Decision-making said to be imposed by the Centre without consulting states

•    Rights of Adivasis, women, backward classes and agrarian communities curtailed

•    Labourers allegedly placed under contractor control

•    States facing mounting fiscal stress due to central policies

•    VB-GRAM (G) Act accused of enabling large-scale corruption

Karnataka DGP (Civil Rights Enforcement) K Ramachandra Rao was suspended with immediate effect, as per a state government order issued on Monday, 19 January. The order cited conduct unbecoming of a government servant and causing embarrassment to the state administration.

The Karnataka government suspended Rao after a purported video showed him in a compromising position with a woman inside his official chamber. The video went viral on social media. Rao rejected the videos outright, terming them "fabricated and false".

Who is K Ramachandra Rao?

Rao is a DGP-rank officer who was heading the Directorate of Civil Rights Enforcement until his suspension. He was promoted to DGP in September 2023 and assumed office in October 2023, the Sunday Guardian reported.

He also served as the Chairman and Managing Director of the Karnataka State Police Housing and Infrastructure Development Corporation Limited.

His stint as the Inspector General of Police (IGP) for the Southern Range was also marred by controversy. In 2014, during a cash seizure near Mysuru’s Yelwal, officials claimed the seized amount was ₹20 lakh, while the accused (Kerala-based merchants) claimed it was around ₹2.27 crore.

Rao, who was present during the seizure, denied all allegations. However, he was transferred soon after.

Allegations of collusion with a businessman surfaced, and a senior police officer was quoted by The Sunday Guardian as saying, “In Rao’s case, the CID has clearly mentioned that there was a great degree of lapse on the part of Rao and a deputy superintendent of police after it was brought to their notice that a few policemen, including a gunman attached to the IGP, were involved in the robbery.”

Rao had denied all wrongdoing in that incident. Despite past controversies, he rose to the state’s top police position, the Sunday Guardian reported.

Ranya Rao’s stepfather

Rao is the stepfather of Kannada actress Harshavardhini Ranya alias Ranya Rao, accused of orchestrating the illegal import of gold worth over ₹12.56 crore from Dubai to India along with two others — businessman Tarun Raju, and jewellery dealer Sahil Jain.

‘Obscene video’ controversy

A viral video showed Rao behaving inappropriately with a woman inside his office while in uniform.

The Karnataka government said in its Monday order that “vide videos and news reports widely broadcast on public news channels and media platforms, it is observed that Dr K Ramachandra Rao has acted in an obscene manner which is unbecoming of a Government Servant and also causing embarrassment to the Government.”

The order said the matter was examined by the state government, which found that the officer's conduct amounted to a violation of Rule 3 of the All India Services (Conduct) Rules, 1968.

The government said it is prima facie satisfied that "it is necessary to place Rao under suspension with immediate effect, pending inquiry".

During the suspension period, Rao will be entitled to subsistence allowance as per Rule 4 of the All India Services (Discipline and Appeal) Rules, 1969.

The order also places restrictions on his movement, stating that during the period of suspension, the officer must not leave headquarters under any circumstances without the written permission of the state government.
