Beware mankind! A new virus discovered in pigs with human pandemic risk

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.

In a heart-breaking incident, 19-year-old Shaun D'Souza, a native of Vittalwadi in Udupi's Kundapur taluk, tragically lost his life in the UAE due to heat stroke.

Shaun, the beloved son of Elias Cyril D'Souza and Pramila D'Souza, originally from Hosabettu, Moodbidri, had been pursuing his college education in the UAE.

He was admitted to a hospital in Ras Al Khaimah, approximately 115 km from Dubai, after collapsing from heatstroke. Despite receiving immediate medical attention, Shaun breathed his last on Sunday, September 15. 

He is deeply mourned by his parents and two siblings. The family, who had been residing near St. Mary's Church in the UAE, are grappling with the profound loss. Shaun’s father, Elias, works as a manager for a private company, while his mother, Pramila, is an accountant.

The local community has come together to offer their support and condolences in this time of sorrow.

Mangaluru, Sept 24: A blanket of gloom descended over Dakshina Kannada and Udupi as heavy rains battered the coastal Karnataka districts on Tuesday. Substantial rainfall has been drenching the region since Monday, intensifying as the day progressed.

In Dakshina Kannada, torrential downpours began early Tuesday, followed by overcast skies and humid conditions. 

The showers persisted intermittently through the afternoon, with areas like Beltangady experiencing moderate rainfall, while Puttur and Bellare bore the brunt of heavier storms. 

Overnight showers were reported in Bantwal, and Mangaluru city, along with its surrounding rural areas, witnessed a steady increase in rainfall, peaking by the evening.

After a brief respite, the return of intense rainfall has brought a welcome drop in temperatures. In Udupi, Karkala, Udupi city, Kundapur, and Hebri taluks all faced substantial rains throughout the day, continuing from late Sunday night.

The Indian Meteorological Department (IMD) has issued a red alert for the coastal districts, predicting more heavy rainfall in the coming hours. 

A yellow alert has been placed for Wednesday, signaling the likelihood of additional downpours. Fishermen have been cautioned to remain vigilant, as the possibility of strong winds looms over the coastal waters.

At least 20 people have been killed as more communication devices detonated in Lebanon a day after simultaneous explosions of pagers across the country left at least a dozen dead and thousands injured.

Explosions were reported in multiple locations in Lebanon, including at the site of a funeral for a child killed in a pager explosion the previous day.

Media reports said that several blasts occurred simultaneously in Beirut similar to what happened on Tuesday. Several explosions were also reported in southern and eastern Lebanon.

Lebanon’s Health Ministry said at least 20 people were killed and more than 450 injured in the new wave of explosions. 

An informed source said that the detonated devices came from the same batch of cargo as the detonated pagers, all imported from the same company.

The Lebanese Army Command called on the people not to gather in the scenes of security incidents to allow the arrival of medical teams.

Civil defense teams are extinguishing the fires that broke out as a result of the explosions, while ambulance teams continue to transport the injured.

The new act of aggression came as top Hezbollah official Sayyed Hashem Saffieddine was delivering a speech affirming that the Israeli acts of terrorism will have their own punishment, stating that the resistance is steadfast and capable of inflicting more defeats on the enemy.

The Hezbollah official said a speech by the movement’s Secretary-General Sayyed Hassan Nasrallah, planned for Thursday, will clarify matters and that the movement will face a new pattern and a new confrontation with the enemy.

Thousands of pagers widely used by resistance factions and also public service workers exploded on Tuesday, leaving at least a dozen dead and around 3,000 people injured.

The Lebanese government has blamed Israel. Hezbollah has promised the Israeli regime will receive ‘just punishment’ for the attacks.

Taiwanese company Gold Apollo said the pagers used in the Israeli deadly terrorist attack on Tuesday had been made by a Hungarian firm, to which the company had authorized its brand on the devices.

The company made the remarks in a statement on Wednesday, identifying the firm as BAC Consulting KFT based in the Hungarian capital Budapest.

The UN Security Council is due to meet on Friday to discuss the latest blasts that hit Lebanon, council president Slovenia said on Wednesday after Lebanon requested an emergency meeting.

UN Secretary-General Antonio Guterres said Wednesday that civilian objects should not be weaponized.

"I think it's very important that there is an effective control of civilian objects, not to weaponize civilian objects -- that should be a rule that... governments should, be able to implement," Guterres said at a briefing at UN headquarters.

"As important as the event in itself, is the indication that this event confirms that there is a serious risk of a dramatic escalation in Lebanon -- and everything must be done to avoid the escalation," he said.

"What has happened is particularly serious, not only because of the number of victims that it caused, but because of the indications that exist that this was triggered, I would say, in advance of a normal way to trigger these things, because there was a risk of this being discovered."

The Euro-Mediterranean Human Rights Monitor described the detonation of pagers and wireless devices in Lebanon on Tuesday and Wednesday as a blatant violation of international law.

The organization said the attack did not only target Hezbollah members but also indiscriminately exploded devices used by civilians.

The timing of the attack indicates that Israel did not take necessary precautions, as it occurred when device users were at home with their families, leading to numerous severe civilian injuries, including children, it said.

Israel's actions constitute a flagrant violation of international humanitarian law, which prohibits indiscriminate attacks and the targeting of civilians and their property, and mandates that warring parties distinguish between civilians and combatants at all times, the rights monitor said.

The organization called for an urgent and independent international investigation into these attacks and pressure on Israel to immediately stop its crimes and prevent further escalation in the region.
