Karnataka’s growth stuck in Bengaluru’s traffic: Amit Shah

Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

Bengaluru, May 19: Containment zones in Karnataka will be much smaller in size under the latest lockdown norms. However, rules and loopholes will be tightened and action against violators will be stringent in order to check the spread of the disease.

Revised guidelines issued by the Centre to the state, reveal containment zones are delineated based on mapping of cases and contacts. Intensive action will be carried out in these areas with the aim of breaking the chain of transmission. Therefore, the area of a containment zone should be appropriately defined by the district administration/local urban bodies with technical inputs at local level.

The health department is considering shrinking the size of containment zones from the existing 100 metres to open up more space for economic activities. Medical education minister K Sudhakar, also a member of the Covid taskforce, said additional chief secretary (health department) Javed Akthar will issue a new definition of a containment zone after the Covid-19 taskforce holds its next meeting.

“We are planning to further shrink it and restrict containment zones to an apartment complex, independent house or even a lane where the Covid-19 patient resides,” Sudhakar said. He went on to say bigger containment zones will impede businesses and normal activities in the vicinity, something which the government wants to avoid.

The minister said Karnataka will also do away with colour-coding districts. “With restrictions being relaxed for almost all activities, it does not make sense to pursue with colour codes. It is either containment zone or outside containment zone,” he said.

In rural areas, the minister said containment zones will be identified by the taluk heads. Government sources say it is difficult to restrict activities to certain areas or smaller location in rural areas as farmers and people will have to travel to the outskirts of their villages for their livelihood.

An official said, a containment operation (large outbreak or cluster) is deemed successful when no case is reported in 28 days from the containment zone.

Bengaluru, Mar 13: Amid coronavirus outbreak, all universities, malls, and clubs will remain closed for a week in Karnataka. Karnataka CM Yediyurappa has said no one should travel unless it's an emergency. "All malls, cinema halls, pubs, wedding ceremonies and other large gatherings in the Karnataka have been banned for another one week," Chief Minister Yediyurappa said. This comes hours after the Uttar Pradesh government had decided that all schools, colleges situated in the state will be closed till 31st March 2020.

Following the decision, the Karnataka government on Friday asked doctors and other health staff to work on public holidays also till the spread of coronavirus is contained. Leaves and all week off of state health ministry workers have also been canceled. The government issued a circular stating that certain emergency measures are being taken to control the spread of coronavirus is some parts of the State.

"To manage things in a result-oriented manner, doctors, office personnel, paramedical staff and other permanent and contract employees in hospitals coming under the Health Department have been instructed to work on all public holidays." the government order read.

The decision comes after 76-year-old man in Karnataka's Kalaburagi died of coronavirus and became India's first COVID-19 victim. 46 people in Kalaburagui have been kept under coronavirus quarantine since then. Out of 46, 31 have been put under the "high risk" category. The high-risk persons were shifted to ESIC hospital. Officials said four family members of the man have displayed flu symptoms and their swab samples have been sent for testing in Bengaluru.

Earlier on Friday, an employee of Google's Bengaluru office tested positive for n-coronavirus, taking the total COVID-19 positive cases in Bengaluru to 5. India's total coronavirus positive count rose to 75. Several other states including capital Delhi, Madhya Pradesh, Odisha, Bihar, and Uttar Pradesh invoked various sections of the epidemic disease act. Meanwhile, the Indian Army has also called off all recruitment drive in wake of coronavirus outbreak.
