Chikkamagaluru reclaims ‘corona-free district’ tag as all 16 patients discharged

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.

Bengaluru, July 25:  Karnataka reported 5,072 new COVID-19 positive cases and 72 deaths on Saturday, taking the total number of cases in the state to 90,942.

The total count includes 55,388 active cases and 1,796 deaths, the state health department said.

Meanwhile, a 100-year-old woman resident of Huvina Hadagali town in Bellary district here recovered from COVID-19 after testing positive for the virus earlier this month.

"Doctors treated me well. Along with regular food, I was eating an apple a day. The doctors are giving me tablets and injection, and I am healthy now. COVID-19 is like a common cold," said Hallamma while speaking to news agency.

The woman's son, daughter-in-law, and grandson had also tested positive for the virus, and the family was treated at their home.

India reported a spike of 48,916 coronavirus cases on Saturday, taking the total number of reported COVID-19 cases to 13,36,861, according to the Union Ministry of Health and Family Welfare.

The total count include 4,56,071 active cases, 8,49,431 cured/discharged/migrated. With 757 deaths in the last 24 hours, the cumulative toll reached 31,358.

Udupi, Jun 28: A student appearing for the Secondary School Leaving Certificate (SSLC) exams in Kaup taluk of Udupi district has tested positive for the novel coronavirus (COVID-19) infection.

Officials of the Department of Public Instruction (DPI) and Udupi District Health and Family Welfare Department have confirmed the report. 

The 16-year-old girl had appeared for the Kannada and Mathematics exams on June 25 and 27 respectively. 

Her throat swabs were sent for testing on June 27 after her father tested covid-19 positive. Today she too obtained positive report.  

The student is unlikely to appear for the science paper on June 29.

Meanwhile, health officers have ruled out the possibility of subjecting other students to covid-19 test as all necessary precautions such as physical distancing and usage of sanitization were taken in the examination centre.
