'Neither Sidddaramaiah nor others have complained against coalition govt'

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.

Jan 2: A year after 12,000 acres of forests in Bandipur went up in smoke, the Karnataka Forest Department is gearing up for the summer even as the Forest Survey of India (FSI) has cautioned that 22.78 lakh acres (9,222 sq km) or about 20% of the green cover spread across three districts in the central part of the state is fire-prone.

The FSI studied forest fire incidents across the country between 2004-05 and 2017 before coming up with state-specific inputs.

According to the 13-year observation, Karnataka has 7,352 “fire points” or areas measuring 5 km X 5 km with frequent fire incidents.

Though the number is lower compared to states like Maharashtra, Madhya Pradesh and Odisha with over 20,000 points, the sheer spread of the fire-prone area itself is a challenge for the Karnataka Forest Department.

According to data, about three lakh acres (1,199.9 sq km) of forest area is very highly fire prone with 26 to 52 fire incidents in 13 years. This is followed by 7.6 lakh acres (3,067 sq km) of “highly fire prone” areas with an average of one to two incidents every year.

Almost all of the “red alert” areas are concentrated in Uttara Kannada, Chikkmagaluru, Shivamogga and Chamarajanagar districts. As temperature rises at the end of January, so does the risk of forest fires, requiring officials to be on vigil till the end of summer.

After an investigation into the Bandipur blaze revealed that faulty fire lines and poor supervision were the reason for the spread of the fire, the department has come up with a multi-pronged approach to prevent similar incidents this year.

“After the Bandipur incident, we have created a fire cell and a standard operating procedure (SOP) which everyone has to follow. Firstly, a fire management plan is prepared and approved by a competent authority.

The SOP has well defined firelines which have to be executed by December-end and burning must be completed by January 15,”  Principal Chief Conservator of Forests (Head of Forest Force) Punati Sridhar told DH.

He said that to ensure its strict implementation, GPS readings of firelines are to be submitted for random verification.

“All the required equipment from fire jackets to shoes, gloves, backpack sprayers and tractors mounted with 2,000-5,000 litre tanks with high pressure pumps will be deployed at vantage points,” he said.

In addition, the department’s fire cell works in collaboration with the Karnataka State Remote Sensing Applications Centre (KSRSAC) to give fire alerts within half and hour of an area catching fire and detected by satellites.

“Earlier, the gap used to be four hours by when the fire would have spread beyond control. Now, with reduced time gap, it would be easier to control fire early,” he added.

Bengaluru, May 4: A total of 37 new COVID-19 cases have been reported in the last 24 hours in Karnataka taking the total number to 651, State Health Department said on Monday.

"Thirty seven new coronavirus positive cases have been confirmed in Karnataka from 5 pm yesterday to 5 pm today. The total number of cases in the state stands at 651," the department said.

The total number of cases includes 27 deaths and 321 persons who have been discharged. Of the remaining 302 cases, 296 patients are in isolation in designated hospitals and six patients are in ICU.

India has registered 2,553 new COVID-19 cases in the last 24 hours and the total number of cases now stands at 44,532.
