Dowry death: Victim’s husband held for abatement of suicide

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.

Mangaluru, July 17: For the first time, Dakshina Kannada saw over 3,00 new coronavirus cases in a single day. The coastal district today recorded 311 positive cases. 

The number of active cases in the district is 1,725 while its overall tally stands at 3,074.

Out of the 26,242 samples tested so far, 23,168 were tested negative. 

As many as 1,278 people were discharged after fully recovering so far including 115 people who were discharged today.

The district also recorded deaths of 8 covid-19 patients in past 24 hours including a woman. The deceased are aged between 53 years and 78 years. 

With this the total number of deaths in the district mounted to 71 including 12 patients from other districts who were admitted in hospitals here. 

Meanwhile, Karnataka reported 3,693 fresh cases in the last 24 hours, which raised the virus case count to 55,115. The number of recoveries reached 20,757, including 1,028 on Friday.

At 115 fatalities, the state witnessed its biggest single-day jump. Bengaluru accounted for 75 of these 115 deaths. The number of active cases in the state are 33,205, including 508 patients who are in ICU. The state's death toll reached 1,147 while that of Bengaluru stands at 582.

With an aim to provide water to stray animals in Mangaluru, an animal activist announced a project 'Jal' under which free water bowls will be distributed to the people across the city.

Tauseef Ahmed believes many animals and birds do not find source to drink water which leads to death.
"Finding clean and safe drinking water has been a major issue in a lot of places. We humans when we face some scarcity we manage by taking the water out from the well," Ahmed told ANI.

"Unfortunately, that's not the case with when it comes to animals and birds. They do not find sources for water to drink so they eventually end up drinking sewage water and they fall sick. In some cases, even that is not available and due to dehydration, they die," he added.

Under the "Jal" project, Ahmed will distribute free water bowls to the people and expects them to make equal efforts in saving the lives of the animals.

"So, this project "Jal" will be providing 100 free water bowls all over Mangaluru. We are distributing it free of cost. All you have to do is keep the bowls outside in the garden or any places where animals frequently visit. Every day, we just have to fill the bowls with water for the animals. It will help a lot of animals to survive in the harsh weather of summers," Ahmed highlighted.

"We have used cement to make the bowls which will keep the eater really cool. We are spending close to 74 rs per bowl. We have made around 100 bowls and will continue making it. We are trying to cover as many animals as we can," he said.
