Sirsi limps back to normalcy after violent protests; security remains tight

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, May 13: Karnataka revised its standard operating procedure (SOP) for international passengers to allow pregnant women, children and senior citizens to entre home quarantine if they test negative for covid-19. 

The development comes after former minister and Mangaluru MLA U T Khader urged the government to follow the Kerala model in handling the repatriates and take extra care of pregnant women and senior citizens at Mangaluru and Bengaluru Airports.

Passengers will be initially dived into two categories. Category A includes passengers symptomatic on arrival while Category B passengers are those asymptomatic on arrival. 

While category A passengers will be directly shifted to covid-19 hospital, category B passengers will be sent to 14-day institutional quarantine.

If there are pregnant women, children below 10 years of age and senior citizens in category B, they will remain in institutional quarantine until they obtain a negative report (after throat swab testing for covid-19). It may take one or two days to get the throat swab testing report. 

Mangaluru, Mar 25 : Taking into account surge of COVID-19  cases in neighbouring districts, Dakshina Kannada district administration has decided to suspend retail sales at Central Market in Mangaluru and public will not be allowed to purchase at Central Market from Thursday.
