Mangaluru: College girl finds wiggling worm in Pepsi float

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, Apr 13: Eminent scientist and NITI Aayog member V K Saraswat said on Monday the number of COVID- 19 cases is not going to go beyond what's being reported daily in India as he maintained that the country is in the process of flattening the curve.

The former Scientific Adviser to Defence Minister said the coronavirus positive cases have seen a sharper rise in the last four-five days because of increase in the number of testing.

"It's a good sign; all those asymptomatic cases lying hidden they are also coming out," Saraswat told PTI. "We certainly had a catalytic factor which was basically this (Nizamuddin) Markaz problem which has actually created clusters at different places and that has also been one of the factors for the kind of rise that has taken place."

But he said India is in a much better shape compared to other nations in the battle against COVID-19. "I can only say that the rate is not going to go beyond what has been going on now, may be 700 to 800 cases per day. So, we are in the process of flattening the curve."

The government's decision to declare nation-wide lockdown has paid dividends, Saraswat, a former chief of the Defence Research and Development Organisation, said.

Noting that India has seen a series of virus attacks in the last 15-20 years including Chikungunya and Dengue, he said the emphasis now should be on more and more R & D to find vaccines in advance.

Bengaluru, May 5: Life is limping back to a new normalcy in most parts of Karnataka with easing of Covid-19 induced restrictions yesterday as the State headed into the third phase of lockdown started since March 24.

According to the guidelines issued by the Centre, industrial activities, construction works, essential, non-essential shops, delivery of essential goods through e- commerce, courier and postal services, banking and agriculture activities, plying of four-wheelers and two-wheelers and inter-state movement of goods vehicles is permitted in all the zones, whereas buses are allowed to ply only in green and orange zone districts.

This apart, sale of liquor was also allowed at the designated shops. Police said vehicular movement is allowed only from 7am to 7pm for ordinary citizens.

Clarifying about the movement of people, Bengaluru police commissioner Bhaskar Rao tweeted, "From Monday you don't need a pass to move in Bengaluru between 7am and 7pm. After 7 pm and up to 7am the following morning, even if you have a pass you are not allowed to move except medical and essential service. Checkpoints will remain and your ID may be asked. Please be responsible." After the restrictions were lifted, heavy vehicular movement was witnessed in parts of Bengaluru leading to traffic jam in some areas.

Chikpet, which is the main trade area in Bengaluru, saw some activities.

With restrictions on public transport continuing, this unusually crowded place had very less footfall. "Movement of public is limited due to ban on public transport, such as city buses and Metro Rail.

"The trade activities are taking place between retailers," trade activist and joint secretary of Jain International Trade Organisation Sajjanraj Mehta said .

Select liquor shops in the city and other parts of the state pulled up shutters after being closed for about six weeks due to the lockdown with tipplers thronging them in huge numbers at many places.

Some traders in the city complained that they received notices regarding the Tax Deduction at Source for the month of April "thought here were no trading activities."

Meanwhile, Chief minister B S Yediyurappa announced on Monday that free bus service for migrant labourers, which is operating smoothly, has been extended till Thursday.
