No proof against Dr Zakir Naik; security agencies asked to probe deeper

Bengaluru, May 15 Reformed underworld don N Muthappa Rai died battling cancer at a private hospital here on Friday, hospital sources said.

Rai, 68, was suffering from brain cancer for the past one year and was admitted at Manipal Hospital on Old Airport Road, where he died at 2.30 am, the sources said. Rai is survived by two sons.

Born into a Tulu-speaking Bunt family in Dakshina Kannada''s Puttur town, Rai entered the crime world at a very young age.

Karnataka police issued arrest warrants against Rai in eight cases, including murder and conspiracy.

In 2002, Rai was deported to India from the United Arab Emirates. On arrival, he was questioned by various investigation agencies such as the Central Bureau of Investigation (CBI), Research and Analysis Wing (RAW) and Intelligence Bureau (IB), and by the Karnataka police. He was later acquitted due to the lack of evidences.

In his reformed years, Rai founded charitable organisation ''Jaya Karnataka''.

Rai has appeared in Tulu film ''Kanchilda Baale'' in 2011 and Kannada film ''Katari Veera Surasundarangi'' in 2012.

Bollywood director Ram Gopal Varma wanted to make a movie based on Rai''s life. The film roped in actor Vivek Oberoi for the lead role and was shot in Bengaluru, Mangaluru, Mumbai, Dubai and London. However, it has not been released due to production delays.

Rai was enthusiastic about the film and even celebrated his birthday with Varma and Oberoi.

After his cancer diagnosis, Rai withdrew from public life and resigned from Jaya Karnataka.

His last rites are likely to be performed at Bidadi on Friday, family sources said.

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.

Udupi, Jun 2: As many as 150 persons tested positive for COVID-19 in Udupi district on Tuesday. This is the highest spike in COVID-19 cases in a single day in the district.

According to the district administration, all the 150 persons have travel history from Maharashtra. The number of COVID-19 cases has more than doubled when compared to June 1, when the district recorded 73 cases.

Deputy Commissioner G. Jagadeesha said here that of the 150 persons who tested positive, 120 were male and 30 female. This also included nine children aged less than 10. All these persons had been shifted to the designated hospitals for treatment.

He said that since 2,000 persons were tested in the last two days, 150 persons were found positive. Earlier, about 200 to 300 persons were being tested daily and about 10 to 15 used to be found positive. Nearly 10 % of persons coming from Mumbai/Maharashtra tested positive for COVID-19.

“We have 1,120 beds to treat COVID-19 positive cases in the district. Even after including these 150 persons, we still have 800 beds left. Hence, people need not panic. We will provide treatment for all affected persons,” Mr. Jagadeesha said.

With 150 cases on Tuesday, the total number of persons who have tested positive in the district since March has touched 410. There are 345 active cases.

As many as 63 persons who had recovered had been discharged from hospitals. There was one death due to the disease on May 14. The test reports of nearly 5,400 persons are still awaited.

The district had recorded only three COVID-19 cases from March 29 to May 14. But the number of COVID-19 cases started increasing from May 15.
