Trump set to clamp down on H-1B visas

Jun 9: The World Health Organization says it still believes the spread of the coronavirus from people without symptoms is “rare,” despite warnings from numerous experts worldwide that such transmission is more frequent and likely explains why the pandemic has been so hard to contain.

Maria Van Kerkhove, WHO''s technical lead on COVID-19 said at a press briefing on Monday that many countries are reporting cases of spread from people who are asymptomatic, or those with no clinical symptoms.

But when questioned in more detail about these cases, Van Kerkhove said many of them turn out to have mild disease, or unusual symptoms.

Although health officials in countries including Britain, the U.S. and elsewhere have warned that COVID-19 is spreading from people without symptoms, WHO has maintained that this type of spread is not a driver of the pandemic and is probably accounts for about 6 per cent of spread, at most.

Numerous studies have suggested that the virus is spreading from people without symptoms, but many of those are either anecdotal reports or based on modeling.

Van Kerkhove said that based on data from countries, when people with no symptoms of COVID-19 are tracked over a long period to see if they spread the disease, there are very few cases of spread.

“We are constantly looking at this data and we''re trying to get more information from countries to truly answer this question,” she said. “It still appears to be rare that asymptomatic individuals actually transmit onward.”

Kabul, Jun 12: A blast in a mosque during Friday prayers in the western part of capital Kabul has killed at least four people and wounded many more, Afghanistan's interior ministry said.

"Explosives placed inside the Sher Shah Suri Mosque exploded during Friday prayers," said a statement issued by the ministry, which added that the mosque's prayer leader Mofleh Frotan was among those killed.

Interior ministry spokesman Tariq Arian said police have cordoned off the area and helped move the wounded to ambulances and nearby hospitals.

No group immediately claimed responsibility for the attack but a mosque attack earlier this month was claimed by an ISIL (or ISIS) group affiliate, headquartered in eastern Afghanistan's Nangarhar province.

"Interestingly, every time you have the peace process gaining some momentum and pace, you have these kinds of attacks in the country," Habib Wardak, a national security analyst based in Kabul, told Al Jazeera.

"The Islamic State group claimed responsibility for the attack that happened last week on a mosque in Kabul, so despite the fact that you have these news and press conference from the government that they have eliminated ISIL, how can they conduct such sophisticated operations?"

Friday's blast had parallels to one earlier this month, when an explosion tore apart a famous Kabul mosque and led to the death of renowned Afghan cleric Maulvi Ayaz Niazi.

"In this attack, the imam seems to be the target, not the rest of the crowd. These are the imams who have supported the peace process with the Taliban movement," Wardak said.

"The other political aspect for these kinds of attacks is that there are peace spoilers trying to convey a message that peace with the Taliban will not eradicate violence in the country because you have ISIL."

Violence has spiked in recent weeks in Afghanistan with most of the attacks claimed by the ISIL affiliate.

The United States blamed the armed group for a horrific attack last month on a maternity hospital in the capital that killed 24 people, including two infants and several new mothers.

The ISIL affiliate also took responsibility for an attack on a bus carrying journalists in Kabul on May 30, killing two.

It also claimed credit for an attack on the funeral of a strongman loyal to the government last month that killed 35 people.

Meanwhile, the US is attempting to broker peace talks between the Afghan government and the Taliban to end 18 years of war.

Washington's peace envoy Zalmay Khalilzad was in the region earlier this week trying to resuscitate a US peace deal with the Taliban.

The peace deal signed in February calls for the withdrawal of the US and NATO troops from Afghanistan in return for a commitment by the Taliban to not launch attacks on the US or its allies.

Beijing, May 24: The Chinese virology institute in the city where COVID-19 first emerged has three live strains of bat coronavirus on-site, but none match the new contagion wreaking chaos across the world, its director has said.

Scientists think COVID-19 -- which first emerged in Wuhan and has killed some 340,000 people worldwide -- originated in bats and could have been transmitted to people via another mammal.

But the director of the Wuhan Institute of Virology told state broadcaster CGTN that claims made by US President Donald Trump and others that the virus could have leaked from the facility were "pure fabrication".

"Now we have three strains of live viruses... But their highest similarity to SARS-CoV-2 only reaches 79.8 percent," she said, referring to the coronavirus strain that causes COVID-19.

US demands immediate start to WHO review

The United States called on the World Health Organisation on Friday to begin working immediately on investigating the source of the novel coronavirus, as well as its handling of the response to the pandemic.

One of their research teams, led by Professor Shi Zhengli, has been researching bat coronaviruses since 2004 and focused on the "source tracing of SARS", the strain behind another virus outbreak nearly two decades ago.

"We know that the whole genome of SARS-CoV-2 is only 80 percent similar to that of SARS. It's an obvious difference," she said.

"So, in Professor Shi's past research, they didn't pay attention to such viruses which are less similar to the SARS virus."

Conspiracy rumours that the biosafety lab was involved in the outbreak swirled online for months before Trump and US Secretary of State Mike Pompeo brought the theory into the mainstream by claiming that there is evidence the pathogen came from the institute.

The lab has said it received samples of the then-unknown virus on December 30, determined the viral genome sequence on January 2 and submitted information on the pathogen to the WHO on January 11.

Wang said in the interview that before it received samples in December, their team had never "encountered, researched or kept the virus."

"In fact, like everyone else, we didn't even know the virus existed," she said. "How could it have leaked from our lab when we never had it?"

The World Health Organization said Washington had offered no evidence to support the "speculative" claims.

In an interview with Scientific American, Shi said the SARS-CoV-2 genome sequence did not match any of the bat coronaviruses her laboratory had previously collected and studied.
