Kerala: India's first Islamic bank gets RBI approval

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.

Thiruvananthapuram, Apr 24: Kerala Chief Minister Pinarayi Vijayan on Thursday said that there is no community spread or the expected phase three spread of coronavirus in the state so far but the threat continues.

Speaking to media persons here on Thursday, Vijayan said that Kasargod, Kannur, Kozhikode, and Malappuram districts will be in the red zone with full restrictions.

"All the other ten districts in the State will be in the orange zone. With the detection of new cases today, the status of Kottayam and Idukki districts have been changed from green to orange. The district administration will decide on the hotspot areas to be closed," he said.

He said there would be an increase in the number of random tests in the red zones.

"In an effort to confirm that there is no community spread in the State, random antibody tests would be conducted among health workers, police personnel, home delivery persons, volunteers and migrant labourers," he added.

The Chief Minister said that COVID-19 labs set up at the Pariyaram Government Medical College at Kannur and the Kottayam Medical College have got the approval from the ICMR for coronavirus testing. The lab at Kannur Medical College will start functioning from Friday.

The UV sterilised lab, spread over 2,200 sq ft is equipped with four real-time PCR machines. In the first phase, this lab will be able to do 15 tests per day, which will be gradually increased to conduct 60 tests in the next phase.

"With the opening of these two new labs, tests to detect COVID-19 will be conducted in 14 government labs in Kerala. Apart from this, there are two private labs also in Kerala which are doing these tests. Since the number of coronavirus cases is again increasing in the State, the government has decided to procure ten real-time PCR machines to ramp up testing," he added.
