No threat to coalition govt after LS results; we will win bypoll too: G Param

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, Mar 29: Seven new COVID-19 cases have been confirmed in Karnataka since Saturday 5 pm to 2 pm on Sunday.

The total number of positive cases in the state stands at 83, out of which five have been cured/discharged and three have lost their lives, according to the Karnataka Health Department.

A total of 979 confirmed cases of COVID-19 have been reported in India, informed the Ministry of Health and Family Welfare on Sunday.

New Delhi, Apr 4: The Supreme Court on Friday urged Karnataka and Kerala to amicably resolve their issues concerning a border blockade that has choked the free flow of vehicles carrying essential items and patients in the midst of the COVID-19 outbreak.

Karnataka, which imposed the blockade, justified that its border was sealed to “combat the spread of the pandemic by preventing the movement of people from the bordering districts of Kerala to Karnataka”.

The State had moved the Supreme Court, challenging a Kerala High Court order on April 1 to open the border. Kerala has countered that patients from the State cannot be denied access to health care. Besides, the blockade has severely affected the supply of essential items, from medicines to food, to Kerala.

On Friday, a Supreme Court Bench of Justices L. Nageswara Rao and Deepak Gupta urged the States to not confront each other in the midst of an unprecedented public health crisis. Instead, it asked the Chief Secretaries of both States to sit with the Union Health Secretary and iron out a solution. Meanwhile, the apex court urged Kerala not to take any precipitative action based on the High Court order.

The court issued notice to Kerala on the appeal filed by Karnataka, represented by advocate Shubhranshu Padhi. It listed the case for further hearing on April 7.

Karnataka, in its appeal against the High Court order, said the blockade was put in place in the interest of public health. The situation regarding Coronavirus was “really dire”, it said. It warned that opening the blockade would cause a law and order issue as its local population wanted the border to remain sealed.

Karnataka argued that Kerala was the “worst-affected” State in the country with nearly 194 coronavirus cases. In this, Kasaragod, adjoining Karnataka, was the “worst affected” district of Kerala with over a 100 positive cases.

MP’s plea

The court also separately considered a writ petition by Kasaragod MP Rajmohan Unnithan for an order to forthwith open the State border.

The parliamentarian, represented by advocates Haris Beeran and Pallavi Pratap, urged the court to issue an ex-parte stay on the operation of the blockade imposed by Karnataka with its border States.

Mr. Unnithan said Karnataka’s blockade was “ill-planned and dangerous” and had led to loss of lives. Two patients from Kerala, in need of urgent medical care, died after their ambulances were denied entry at the border by the Karnataka authorities.
