On I-Day, PM Modi expresses concern over growing population in India

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.

New Delhi, Feb 11: As the counting of votes for the Delhi Assembly polls began, Congress leader Digvijaya Singh on Tuesday raised doubts on EVMs, alleging that no machine having a chip is tamper-proof.

He called upon the Election Commission and the Supreme Court to take a fresh look at the use of EVMs in the country.

"No machine (which) has a chip is tamper-proof. Also please do for a moment think, why no developed country uses EVM," Singh said in a tweet.

"Would CEC and Hon Supreme Court please have a fresh look on EVM voting in India? We are the largest democracy in the world, we can't allow some unscrupulous people to hack results and steal the mandate of 1.3 billion people.

"If they match the votes in the counting unit. Declare the result. If they don't match then count the ballots of all polling booths in the assembly. It would convince everyone and save time also as this has been the consistent argument of CEC in favour of EVM," the Congress leader said.

Polling for the 70-member Delhi Assembly polls was held on Saturday.

The Election Commission on Sunday announced that the final voter turnout was 62.59 per cent, five per cent less than 2015.

New Delhi, May 26: With India now in the bracket of top 10 nations worst hit by the novel coronavirus, experts have attributed the surge in cases to easing of travel restrictions and movement of migrants besides enhanced testing capacity.

According to AIIMS Director, Randeep Guleria, the present rise in cases has been reported predominantly from hotspot areas but there is a possibility of further rise in the number of COVID-19 cases in the coming few days due to increased travel.

"Those who are asymptomatic or are in presymptomatic stage will pass through screening mechanisms and may reach areas where there have been minimal or less cases," Guleria said.

He said there was a need for more intense surveillance and monitoring in areas where migrants have returned to contain the spread of the disease.

If proper social distancing and hand hygiene is not maintained at a time when people are out on roads, the coronavirus infection will transmit much faster, he said.

Guleria also noted that testing capacity has been significantly ramped up which is reflecting in the increasing number of cases being detected.

Commenting on the partial resumption of rail and road transport services and migrants returning to their native places, Dr Chandrakant S Pandav, former president of the Indian Public Health Association and Indian Association of Preventive and social medicine, said the floodgates have been opened.

"This is a classic case of creating an enabling environment for coronavirus to spread like wildfire. In the coming few days, the number will rise dramatically. While it is true that lockdown cannot go on forever, the opening up should have been in a measured, calibrated and informed manner," he said.

"Travelling leads to spread of the infection. Now, the government will have to ensure even stronger surveillance to curb the infection but if that will be done is something to be observed," he said.

The death toll due to COVID-19 rose to 4,167 and the number of cases climbed to 1, 45,380 in the country, registering an increase of 146 deaths and 6,535 cases since Monday 8 am, according to the Union Health Ministry.

Dr K K Aggarwal, President of the Confederation of Medical Association of Asia and Oceania (CMAAO), and former IMA President, said there will be a further surge in cases in the coming days if migration continues without any proper social distancing.

"Within the next ten days, the cases will cross two lakh. The very fact that number of cases was rising before the end of the third lockdown and continuing during the fourth lockdown means that people are not following physical distancing as required," he said.

"Even in the last week of May when the temperature is very high, the rising number of cases would mean that human-to-human transmission is more important than surface-to-human transmission. Normally in heat the surface-to-human transmission should have reduced the new cases by half which has not happened," Aggarwal said.

However, Professor K Srinath Reddy, president of the Public Health Foundation of India, said an increase in the number of cases reflects both an increase in testing rates and an increase in spread.

"What we need to see is the number of new tests performed per day and the number of new cases that were identified from them. That gives a better idea of the rate of spread than the total number of new cases alone.

"We also have to see if the testing criteria has remained the same between the two periods of comparison.We may open up gradually but will have to continue case detection, contact tracing and follow personal protection measures as vigorously as possible," he added.

A total of 31,26,119 samples have been tested as on May 26, 9 am and 92,528 samples have been tested in the last 24 hours, ICMR officials said.

India is the tenth most affected nation by the pandemic after the US, Russia, UK, Spain, Italy, Brazil, Germany, Turkey and France, as per the John Hopkins University data.

The country has recorded 6,088, 6,654, 6,767 and 6977 cases on May 22, 23, 24 and 25 respectively. Also, the number of RT-PCR tests for detection of COVID-19 in the country crossed the 30-lakh mark on Monday.

The first two phases of the lockdown led to 14-29 lakh COVID-19 cases being averted, while the number of lives saved in that period was between 37,000 and 78,000, the government said last Friday, citing various studies, and asserted that the unprecedented shutdown has paid "rich dividends" in the fight against the pandemic.
