Stop harassing Muslims, Latinos, black people: Trump tells Americans

Wayanad/Thiruvananthapuram, Apr 24: Amid the strict lockdown, a school teacher travelled from Thiruvananthapuram to Muthanga in Wayanad -- a distance of about 465 km -- on her way to neighbouring Karnataka en route to Delhi following which cases have been registered against her and an excise official.

The woman, Kamna Sharma, said to be working in Kendriya Vidyalaya, Pattom, undertook the journey on April 21 along with her two year-old daughter, police sources told news agency PTI.

An Excise Circle Inspector, Shahjahan, had provided his vehicle to travel allegedly on the instructions of Malappuram excise officer, in whose private vehicle, the woman and the child had reached Wayanad border from Thiruvananthapuram, the sources said.

The two were charged under the Kerala Epidemic Act and various sections of the IPC including sect 269 (negligent act likely to spread infection) and 271 (disobedience to quarantine rule).

Because of the lockdown even inter-district travel is not allowed by police and district administration, unless there is an extremely genuine reason.

A senior police official in Thiruvananthapuram said he does not remember issuing any such pass.

The woman may have "misused" government machinery as private vehicles would have been stopped somewhere during the long journey, he said.

She came to Kalpetta in Wayanad allegedly in an official car of the excise department.

Wayanad District police chief R Elango said that an FIR has been filed based on preliminary information and investigations have begun.

"We will check if she has followed procedures in obtaining a pass and if she made any false claim to get the pass."

As per preliminary information the woman came in an excise official's car from Thamarassery (Kozhikode) to Muthunga(Wayanad), he said. Her mode of transport before that--from Thiruvananthapuram to Wayanad--will also be investigated, he said, adding they have no information if she has reached Delhi.

"We will track down her movement," he said Meanwhile, theWayanad district administration has intensified the lockdown protocol from Thursday to prevent people's movement within and from outside the district/state.

Interception at all the check posts on district an state borders of the district, bordering Tamil Nadu and Karnataka, will also be intensified. No one would be allowed to travel frequently to and fro the district under the pretext of official duty.

Wayanad collector Adhila Abdulla said officials from outside the district will no longer be allowed to commute daily.

"Elderly people above the age of 65 should confine to their homes unless it is extremely urgent or unavoidable. Cases will be registered against family members who allow elderly people to go out for buying medicines and other essentials," she said.

Senior citizens, who live alone, can call either the Fire (101) or Police (100) departments for any help and to get things they need, the collector said.

Whatever relaxations were in place have also been withdrawn with effect from Thursday, she added.

Wayanad and Thiruvananthapuram come under the "Orange B" zone where there are some relaxations.

However, Thiruvananthapuram city limits falls under the hotspot area.

Police said a case was also registered against a doctor and her husband who entered Kerala from Tamil Nadu border.

Mangaluru, Apr 16: An old refrigerator has been turned into a "disinfection chamber" by researchers who are striving to come up with solutions to tackle the spread of coronavirus.

Dr Arun M Isloor, head of Chemistry Department, National Institute of Technology Karnataka (NITK), Surathkal, along with research scholar Syed Ibrahim has come up with the device which can disinfect items kept inside it.

"We have named this as ZERO-COV," Dr Isloor said.

He says the device ensures 99.9 per cent destruction of microorganisms present on the surface of items.

"We can keep items like vegetables, currency notes, books or envelopes inside the chamber. Switching on the chamber for 15 minutes ensures 99.9 per cent destruction of microorganisms present in the surface of the items," Dr Isloor added.

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.
