The previous biggest single-day spurt was recorded on June 2 with 388 cases.

Of the 515 fresh cases reported, 482 are returnees from other states, mostly (about 471) from neighboring Maharashtra. Udupi district saw a major spike with over 200 cases today and the total tally of the district breaching seven hundred cases mark, to stand at 768.

The new cases include 471 from Maharashtra, three from Delhi, two each from Andhra Pradesh, Telangana and Haryana, and one from Tamil Nadu.

While one is with international travel history from Indonesia. Remaining cases include- contacts of patients earlier tested positive, those from containment zones, those who travelled from other districts, and the ones whose contact history is still being traced.

Among the districts where new cases were reported, Udupi accounts for 204 cases, followed by 74 from Yadgir, Vijayapura 53, Kalaburagi 42, Bidar 39, Belagavi 36, Mandya 13, Bengaluru Rural 12, Bengaluru Urban 10, Dakshina Kannada 8, Uttara Kannada 7, three each from Hassan, Dharwad and Chikkaballapura, two each from Ramanagara and Haveri, and one each from Davangere, Bagalkote, Ballari and Kolar.

Udupi district tops the list of positive cases, with a total of 768 infections, followed by Kalaburagi 552 and Bengaluru urban 434.

Among discharges, Bengaluru urban still tops the list with total 271 discharges, followed by Davangere 147 and Mandya 146.

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.
