21 new COVID-19 cases in Kerala including 8 from Kasaragod

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.

Bengalur, May 2: Two people died of COVID-19 in Karnataka on Saturday taking the toll in the state to 25, whereas nine more tested positive for the virus, pushing the tally to 598, the health department said. Two deaths were reported in Bidar and Bengaluru urban, the health department said in a statement.

An 82-year-old person with a history of Severe Acute Respiratory Illness died in Bidar. While the second fatality was a 62-year-old man with a history of diabetes, hyper-tension, renal failture and was on multiple myeloma on chemotherapy, in Bengaluru. He too had complained of breathlessness on April 30 and died on Saturday at the designated hospital.

Among the nine new cases, two each are from Tumakuru, Vijayapura, one each from Bidar, Chikkaballapura, Belagavi, Bagalkot and Bengaluru urban. Cumulatively, 598 COVID-19 positive cases have been confirmed in the state and it includes 25 deaths.

Bengaluru, Apr 11: Former prime minister H D Deve Gowda claimed the lockdown decision was taken in 'haste' without forethought because of which farmers and the working class were 'suffering' and suggested measures to mitigate the impact. The state government should have consulted experienced citizens, officials, progressive farmers, farmer organisations and wholesale traders about the pros and cons before lockdown, he said in a letter to Chief Minister B S Yediyurappa, while highlighting that 61 per cent of the state's population depended on agriculture.

Because of the "hasty decision taken without any preparations", farmers of the country and the state are facing financial distress," he said in the April 9 letter, a copy of which was released to media here on Friday. The JD(S) patriarch suggested taking up some measures, including ensuring no restrictions on agriculture activities, procurement of horticulture produce at a fair price, relaxing export curbs on it, to provide relief to farmers, agriculture labourers, and daily wage workers.

On Sunday, Gowda had said he has assured Prime Minister Narendra Modi of his support in the nation's battle against COVID-19 pandemic when the latter called him to discuss the situation. In his letter to the chief minister, Gowda said: "...the lockdown implemented to control the spread of coronavirus has led our farmers into despair and put their lives into a burning fire.

This lockdown looks like a decision taken at haste without proper thinking and forethought for our farmers, agriculture labourers, and daily wage workers." He said the lockdown decision was taken after remaining 'quite' for about two months since the first corona infection was reported in the country on January 30. Among the suggestions made by the former prime minister include, procurement of horticulture produce at a fair price like in the case of milk from villages by the government through related organisations like Karnataka Horticulture Federation, HOPCOMS among others.

As horticulture produce was perishable, there should be no restriction on its procurement, transportation and marketing; all processing related activities of horticulture produce should be given relaxation from the lockdown, he said. Gowda also called for relaxation on exports for horticulture produce and its processed items. There should be no restriction on agriculture activities; a national grid has to be set up for marketing of horticulture produce, he said.

If such measures were not taken up immediately, the government will have to pay compensation to farmers for losses. Lack of remedial measures would lead to a shortage of supply, leading to rebellion from the people and may result in farmers' suicides and bringing about a situation that might be more grave than coroanvirus, he said.
