No trace of missing Malpe fishermen even after 28 days

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, Mar 31: The Kerala government

on Tuesday rejected concerns of community spread of novel coronavirus in the state in the wake of the second death of a patient here who had no travel history or reported contact with any infected person.

Setting aside the concern, Health Minister K K Shylaja said the deceased man, a native of nearby Pothancode, was already suffering from several other health issues including high blood pressure.

The 68-yearold man died at the government medical college here, taking the total number of COVID-19 deaths in Kerala to two, the government said.

"We have got information that the deceased man had come in contact with some persons arrived from the Gulf. As he was very sick and was not in a position to speak, we could not collect details from him directly," she told reporters here.

"So we had to collect such details from his relatives now. As per preliminary assessment, it was a case of contact spread. So, as of now, there is no need to get panic about the community spread," she said

The possibility of death was high among patients, aged above 60 years and suffering from other diseases like heart ailments or diabetics, she said.

"That's why we are giving strict directions to the elderly people to remain in homes and avoid contact with infected persons, " the minister said.

However, the minister directed those came in contact with the deceased person to remain in self-quarantine and inform the authorities if they developed any infection symptoms.

In both the coronavirus deaths in the state, the deceased persons were aged and were suffering from other diseases, she added.

Tumkur, Jun 2: Karnataka Agriculture Minister BC Patil on Monday said that state will not be affected due to locust swarm as it has moved to other states.

"There will be no effect as locust insects diverted to other states after they came from Pakistan. We were also worried and were prepared to face it, luckily we will not be affected by insects," he said.

Locust is a type of grasshoppers and moves in large numbers and devastates crops. Several parts of Rajasthan including Ganganagar have reported locust attacks.

There is a prediction of another attack in June this year.
