SSLC toppers: Ranjan scores 625/625, many others score 624, 623...

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.

Udupi, July 1: In a concerning development, another SSLC student in Udupi district has tested positive for covid-19.

With this the number of covid-19 patients among SSLC students in the coastal district rose to three. All of them are girls.

The fresh case has been reported from Byndoor. She has already written three papers.

She had reportedly developed some of the symptoms and hence her throat swabs were sent for testing on June 30. Today she received positive report, sources said.

Newsroom, Apr 22: Dozens of Tablighi Jamaat members from across the country who have been successfully recovered and have now tested negative for the novel coronavirus have come forward and donate their plasma for the treatment of Covid-19 patients.

The Tablighis from Tamil Nadu were the first to take this decision. According to them, apart from helping the critically ill patients to recover from COVID-19, was to counter the ‘baseless accusations’ that Tablighis were responsible for the spread of the virus following the religious congregation of the sect held at Delhi’s Nizamuddin area last month.

Mohammad Abbas, a thirty-eight year old businessman from Tiruppur was on Sunday discharged from Coimbatore’s ESI hospital. “As soon as I got discharged, I met the district administration officials and the dean of the hospital and told them that they may contact me anytime if they needed me to donate my plasma,” Abbas was quoted as saying by an English daily.

“It has only been one day since I was discharged but I’ve already spoken to others (from the Jamaat) who have recovered and they were all ready to donate,” he added. 

Leader's call

Maulana Saad Kandhalvi, a prominent leader of Tablighi Jamaat, who has been booked by the Delhi Police for holding a religious congregation, too has appealed to coronavirus survivors to donate blood plasma for infected people.

In a letter issued on Tuesday, Saad said most of the members who were quarantined did not have any infection and they tested negative for COVID-19.

"Even from amongst the ones who tested positive for the disease, a majority of them have now undergone treatment and are now cured while I and a few others are still under quarantine.

"It is required that such people who are now cured of this disease should donate blood plasma to others who are still fighting the disease and are under treatment," he said.

He also has urged the followers of the organisation to pray at home in the month of Ramadan instead of going to mosques. 

Plasma therapy

Convalescent Plasma Therapy is an experimental procedure for COVID-19 patients.

In this therapy, the antibodies of a person who has recovered from the virus are taken and transfused into a sick person (having the virus) to help boost the person’s immune system.

The recovered COVID-19 patient’s blood develops antibodies to battle against COVID-19.

Once the blood of the first patient is infused to the second patient, those antibodies will start fighting against the coronavirus in the second person.

The process for donating plasma is similar to donating blood and takes about an hour.

Several countries around the world including the United Kingdom and the United States have also started plasma therapy trials.

In India, several states like Kerala, Gujarat and Punjab have already started using Plasma Therapy for the corona-infected patients.
