Hat-trick victory for Nalin Kumar Kateel as Congress bites the dust in DK

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.

Mangaluru/Udupi, Jun 24: Dakshina Kannada reported 12 new coronavirus positive cases where as neighbouring Udupi district reported 14 new cases today. Dakshina Kannada also reported a covid related death. 

Among the 12 cases in DK, 8 are males and 4 females. Four among them had recently come from Sharjah. One is suffering from severe acute respiratory infections (SARI) and seven with influenza like illness (ILI) symptoms.

In Udupi, there were two children among 14 people who tested positive today. There are 8 males and 6 females. Nine are Maharashtra returnees, one has travelled from Bengaluru, three have contracted infection from P-3851, and the source of infection of one more patient is being traced.

Mangaluru, Apr 10: Complaints have been registered after it came to light that the conditional permission to enter the Dakshina Kannada district for non-COVID-19 patients from Kerala has been misused on two occasions.

Police said on Friday that the Patients are allowed into the district after filling an online form and getting it authorised from the medical officer from Kasargod district hospital.

On April 9, a patient had arrvived at the district hospital complaining of head ache. After preliminary check up by the physician he left in an ambulance that had arrived from Kasargod earlier carrying another patient without informing the physician.
