Omicron may have emerged in Karnataka much earlier, says Epidemiologist

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.

Prime Minister Narendra Modi, during his visit to Thiruvananthapuram on Friday, January 23, indicated that the Bharatiya Janata Party (BJP) is aiming to expand its political footprint in Kerala ahead of the Assembly elections scheduled in the coming months.

Speaking at a BJP-organised public meeting, Modi drew parallels between the party’s early electoral gains in Gujarat and its recent victory in the Thiruvananthapuram Municipal Corporation. The civic body win, which ended decades of Left control, was cited by the Prime Minister as a possible starting point for the party’s broader ambitions in the state.

Recalling BJP’s political trajectory in Gujarat, Modi said the party was largely insignificant before 1987 and received little media attention. He pointed out that the BJP’s first major breakthrough came with its victory in the Ahmedabad Municipal Corporation that year.

“Just as our journey in Gujarat began with one city, Kerala’s journey has also started with a single city,” Modi said, suggesting that the party’s municipal-level success could translate into wider electoral acceptance.

The Prime Minister alleged that successive governments led by the Left Democratic Front (LDF) and the United Democratic Front (UDF) had failed to adequately develop Thiruvananthapuram. He accused both fronts of corruption and neglect, claiming that basic infrastructure and facilities were denied to the capital city for decades.

According to Modi, the BJP’s control of the civic body represents a shift driven by public dissatisfaction with the existing political alternatives. He asserted that the BJP administration in Thiruvananthapuram had begun working towards development, though no specific details or timelines were outlined.

Addressing the gathering at Putharikandam Maidan, Modi said the BJP intended to project Thiruvananthapuram as a “model city,” reiterating his party’s commitment to governance-led change.

The Prime Minister’s visit to Kerala also included the inauguration of several development projects and the flagging off of new train services, as the BJP intensifies its political outreach in the poll-bound state.

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
