Prohibitory orders issued in Bengaluru to enforce lockdown till May 3

Mangaluru, Apr 12: A 10-month-old baby who tested COVID-19 positive on March 27 completed treatment and discharged from hospital on Saturday.

He was the youngest positive case in Karnataka, from Sajipanadu village in Bantwal taluk.

The child had been with his mother to a relative's house at Monetepadau village, situated on the Karnataka-Kerala border in the first week of March.

A few days later the child developed an acute respiratory illness and tested positive for the COVID-19 virus.

Treating the breastfeeding child was challenging for doctors as he had to be isolated. A team of doctors from Wenlock Hospital took up this challenge and successfully cured the baby.

Test reports on his mother and grandmother too have returned negative. They too had been under quarantine and were discharged with the baby.

Another positive development was that no COVID-19 case has been reported from the child's village.  

The entire Sajipanadu village was completely sealed after the child tested positive and the district had provided all the necessary supplies to the villagers.

Bengaluru, Mar 28: Karnataka has reported 10 new positive cases of COVID-19 between 5 pm yesterday and 8 am today, taking the tally to 74 in the state.

"Ten new COVID-19 cases have been reported between 5 pm yesterday and 8 am today, taking the total number to 74 in Karnataka, which includes three deaths and five cured/discharged persons," said the State Health Department on Saturday.

The total number of active COVID-19 cases in the country has climbed to 873, including 78 cured, discharged and migrated cases and 19 deaths, Ministry of Health and Family Welfare said on Saturday.

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.
