New Delhi, Oct 9: The SARS-CoV-2 virus, which causes Covid-19, may linger on human skin for nine hours, much longer than the flu viruses can, according to a study.

The influenza A virus (IAV), in contrast, remained viable on human skin for nearly two hours, said the researchers including those from Kyoto Prefectural University of Medicine in Japan.

The study, published in the journal Clinical Infectious Diseases, found that both the viruses were rapidly inactivated on skin with a hand sanitiser.

The finding underscores the importance of handwashing or using a sanitiser to prevent the spread of Covid-19.

The researchers noted that the stability of SARS-CoV-2 on human skin remains unknown, considering the hazards of viral exposure to humans.

"We generated a model that allows the safe reproduction of clinical studies on the application of pathogens to human skin and elucidated the stability of SARS-CoV-2 on the human skin," the researchers wrote in the journal

They evaluated the stability of SARS-CoV-2 and IAV, mixed with culture medium or upper respiratory mucus, on human skin surfaces.

The researchers also evaluated the disinfection effectiveness on skin of 80 per cent ethanol against SARS-CoV-2 and IAV.

The study found that SARS-CoV-2 and IAV were inactivated more rapidly on skin surfaces than on other surfaces such as stainless steel, glass and plastic.

The survival time was significantly longer -- 9 hours -- for SARS-CoV-2 than for IAV (1.82 hours), according to the researchers.

"The nine-hour survival of SARS-CoV-2 on human skin may increase the risk of contact transmission in comparison with IAV, thus accelerating the pandemic," the researchers wrote in the journal.

"Proper hand hygiene is important to prevent the spread of SARS-CoV-2 infections," they said.

Mangaluru: The coastal districts of Dakshina Kannada and Udupi are witnessing a fascinating weather pattern, with chilly early mornings giving way to dry, sweltering afternoons. Over the past two days, dense fog blanketed the rural landscapes, while urban centers like Mangaluru felt the stark contrast of brisk mornings and peak afternoon heat.

The India Meteorological Department (IMD) noted that in rural areas, the morning chill caused temperatures to dip by one to two degrees Celsius below the seasonal norm, intensifying the fog. Monday saw Mangaluru recording a maximum temperature of 33.3°C and a minimum of 22.6°C, reflective of the sharp day-night variation.

While mornings painted a serene picture with mist-covered trees and a cool ambiance, the afternoons proved relentless, with temperatures soaring between 11 am and 3 pm, offering little respite. Currently, there are no signs of rainfall, with forecasts predicting the continuation of this dual weather pattern for the coming days.

Local residents have mixed feelings about this weather trend. Farmers in rural areas appreciate the cool mornings that ease early chores but express concerns over the dry afternoons, which may affect crop irrigation if the dry spell prolongs. In contrast, urban dwellers are enjoying the foggy mornings but brace for the scorching afternoons.

Meteorologists attribute the sudden chill to shifts in atmospheric pressure along the coast, a precursor to possible weather transitions in December. Whether this pattern persists or leads to unexpected changes remains to be seen, but the twin districts are clearly caught in nature's dramatic play of contrasts.

The Karnataka Police’s Anti-Naxal Force (ANF) achieved a major breakthrough on Monday night by eliminating Vikram Gowda, one of Karnataka’s most wanted Naxal leaders for over two decades. The encounter occurred in the dense Kabbinale forest of Udupi district, marking a significant victory against Naxal insurgency in the region.

Who Was Vikram Gowda?

Hailing from Hebri in Udupi, Vikram Gowda, 44, was a prominent figure in the Naxal movement. He went underground in 2002, initially serving as a courier and fund collector before rising to lead a breakaway Naxal group. Despite having only a fourth-grade education, he was a staunch advocate for tribal rights and a key player in the movement’s survival in Karnataka.

Bounty: ₹3 lakh from Karnataka and ₹50,000 from Kerala.

Legacy: The last major Naxal leader in Karnataka after the 2021 arrest of B G Krishnamurthy.

The Encounter

Police revealed that Gowda and his team visited Kabbinale village to collect groceries on Monday night. Acting on a tip-off, ANF ambushed the group. When the Naxals opened fire, ANF responded, leading to Gowda's death.

Escapees: Three Naxals fled, including prominent members Latha (aka Mundgaru Latha) and Raju.

Significance: This was the first Naxal casualty in Karnataka in over two decades.

Home Minister G. Parameshwara confirmed the operation, stating, “Gowda was elusive for 20 years, escaping multiple encounters. His death is a critical step in dismantling Naxal operations in the region.”

The Decline of Naxal Activity in Karnataka

Karnataka's Naxal movement has been dwindling, with members seeking refuge in Kerala and Tamil Nadu. The group’s strength had reduced to just 19 members by 2018, but recent sightings indicate attempts at revival:

2023 Activity: Reports of Gowda-led movements in the Kodagu and Hassan districts reignited concerns.

Political Heat: The BJP criticised the Congress government, alleging it created a “safe haven” for Naxals.

A Glimpse into Gowda’s Past

Personal Life: Gowda’s ex-wife, Savitri (alias Rajita), was arrested in 2021. She was a senior Naxal commander involved in insurgency since 2004.
Rehabilitation Efforts: Since 2013, Karnataka’s rehabilitation policy has seen 14 Naxals surrender and reintegrate into mainstream society.

A Milestone in Karnataka’s Fight Against Insurgency

The operation signifies a decisive blow to Naxal resurgence in the Western Ghats. While the ANF continues its search for escapees, the Karnataka government reaffirmed its commitment to offering rehabilitation to those willing to surrender.

As Karnataka celebrates this triumph, the message is clear: there is no room for insurgency in the state.

Mangaluru: Dakshina Kannada MP Captain Brijesh Chowta recently met with Union Minister for Railways Ashwini Vaishnav to discuss urgent concerns regarding the region's railway infrastructure development. Key issues raised during the meeting included the long-pending Mangaluru-Bengaluru connectivity, the Shiradi Ghat stretch, and other vital railway concerns impacting the region.

In addition to discussing these issues, Captain Chowta submitted a letter requesting the Union Minister's intervention and support. The letter emphasized the need to merge Konkan Railway with Indian Railways and called for the doubling of railway tracks between Bengaluru and Mangaluru, which would significantly improve rail connectivity between the state capital and Mangaluru.

Further, Captain Chowta raised concerns about enhancing passenger facilities along the region's rail routes, particularly the need for better services between Subrahmanya and Mangaluru.

To bring more attention to these pressing issues, Captain Chowta took to social media, urging the state government’s support. In a tweet on his official X handle, he requested Chief Minister Siddaramaiah to expedite the resolution of these concerns. “In this direction, I request our Karnataka government led by CM Shri @siddaramaiah to kindly provide the necessary state support for the swift redressal of various concerns pertaining to both Konkan Railways as well as HMRDC to ease movement of both people and cargo in this important stretch between Mangalore and Bangalore,” he posted.

The meeting with the Union Minister was attended by Bengaluru Rural MP Dr. CN Manjunath, Udupi-Chikmagalur MP Kota Srinivas Poojary, and Uttara Karnataka MP Vishweshwara Hegde Kageri, all of whom supported the discussion on enhancing railway infrastructure in the region.
