Mangaluru: Prof. PCM Kunhi no more

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, July 17: For the first time, Dakshina Kannada saw over 3,00 new coronavirus cases in a single day. The coastal district today recorded 311 positive cases. 

The number of active cases in the district is 1,725 while its overall tally stands at 3,074.

Out of the 26,242 samples tested so far, 23,168 were tested negative. 

As many as 1,278 people were discharged after fully recovering so far including 115 people who were discharged today.

The district also recorded deaths of 8 covid-19 patients in past 24 hours including a woman. The deceased are aged between 53 years and 78 years. 

With this the total number of deaths in the district mounted to 71 including 12 patients from other districts who were admitted in hospitals here. 

Meanwhile, Karnataka reported 3,693 fresh cases in the last 24 hours, which raised the virus case count to 55,115. The number of recoveries reached 20,757, including 1,028 on Friday.

At 115 fatalities, the state witnessed its biggest single-day jump. Bengaluru accounted for 75 of these 115 deaths. The number of active cases in the state are 33,205, including 508 patients who are in ICU. The state's death toll reached 1,147 while that of Bengaluru stands at 582.

Mangaluru, May 23: In order to ensure that students do not miss out on their studies due to educational institutions being shut owing to the coronavirus lockdown, Dakshina Kannada Pre-university College Principles Association (DKPUCPA) is conducting online classes on YouTube for pre-university students.

The online lessons are shot by lecturers at St Aloysius College and the lectures are then uploaded on YouTube enabling students to watch them online.

"The whole world is currently in a crucial situation because of COVID-19, and because of the lockdown, all are forced to stay indoors. Usually, we used to conduct lectures in a class full of students, but now it is a new experience that we are providing the same information to students in their absence," Rajaram Rao, a lecturer said while speaking to news agency.

He said at present these classes are being conducted for second year pre-university students.

If any student has a doubt on any concept, he said they can contact the teachers. "At present, students also are getting information about the teachers who have uploaded the videos. All the information about the teachers is already being uploaded on the system so that they can contact the teacher," he said.

Dhanya, a student, hailed the DKPUCPA for the setting up of the online classes despite the prevailing situation.

"The teachers who have taught in these classes have taught very well, as if they are teaching right in front of us. It has been very useful for me during this time," she said.

The nationwide lockdown imposed to combat the threat posed by the coronavirus pandemic has been extended to May 31.
