Mangaluru, Mumbai to be first Indian cities to submerge: NASA study

Mangaluru, Jul 16: Streets in Mangaluru wore a deserted look as the city woke up to the first morning of the seven-day lockdown on Thursday.

The lockdown is being observed after the state government announced it as a necessary step to combat the spread of COVID-19.

The week-long total shutdown came into effect in the Karnataka's Dakshina Kannada district from 8 pm on July 15 till 5 am on July 22.

The state government allowed relaxation between 8am to 11 am for purchasing of essential commodities. A slight rush was observed during the hours of the relaxation.

Karnataka has so far reported 47,253 positive COVID-19 cases, including 27,859 active cases and 18,466 recoveries.

So far, 928 people have lost their lives due to the infectious virus in the state.

Bengaluru, Jul 22: Yellow alert has been issued for Karnataka's Shivamogga, Chikmagalur, Hassan, and Kodagu for July 23 and 24.

Some areas of Bengaluru may receive light rainfall today, said CS Patil, Director, IMD Centre, Bengaluru.

He added that coastal areas of the state are very likely to experience rainfall from on July 23 and July 24, and that rainfall may increase July 24 onwards. Widespread rainfall is predicted for July 24th, 25th, and 26th.

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.
