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, June 21: An assistant sub-inspector of police who was undergoing treatment for COVID-19 infection in city-based Victoria hospital passed away on the intervening night of Saturday and Sunday as he did not respond to the treatment for coronavirus.

The 59-year-old ASI was attached to the Wilson Garden traffic police station in Bengaluru. He tested positive for coronavirus on June 18 and was rushed to the COVID ward in Victoria hospital on June 19. He had fever for the last four days. His wife and two children have been quarantined. According to the police, the station has not yet been sealed down and no policemen have been quarantined.

The Wilson Garden ASI is the third Bengaluru police personnel to die of COVID-19 in the last one week. Earlier, an ASI from the VV Puram traffic police station had died undergoing treatment. On Saturday morning, a head constable from the Kalasipalya police station who was admitted at Victoria hospital passed away. The series of deaths in the police department has created fear among other policemen across the city.

One the other hand, dozens of policemen were tested positive in different parts of Karnataka today including 21 from two police stations of Bengaluru. 

Around 15 policemen from the Kalasipalya police station and five policemen from the Ashok Nagar traffic police station tested positive for coronavirus on Sunday.

In Kalasipalya, three ASIs, head constables and police constables have tested positive. In Ashok Nagar traffic police station, a probationary sub-inspector, an ASI, two police constables and a lady constable tested positive for the virus.

One more police constable working in Bandepalya police station also tested positive. Seven policemen who were in his primary contacts have been quarantined. BBMP officials have begun the process of fumigating the station premises and its surroundings.

Bengaluru, Jul 17: The Doctors at Fortis Hospital, here on Friday, successfully treated a 97-year-old patient who suffered an embolic stroke due to calcified stenosis (narrowing of an artery resulting in restriction of blood flow).

In a release, the Hospital authorities stated that the team of doctors led by Dr Rajpal Singh, Director and Interventional Cardiologist, Fortis Hospital, Bangalore successfully conducted Carotid Artery Stenting (CAS) to increase the blood flow in the blocked areas which had resulted in stroke following stringent safety protocols and ensuring proper segregation of COVID and Non-COVID patients at the hospital.

Carotid arteries serve as the main channels which supply the blood flow to the brain and facial structures. Any significant narrowing in these arteries can cause a brain stroke, a mini-stroke, headache, and neurological symptoms.
