Putin says 'clever' Trump will soon grasp weighty role

Houston, Mar 15: Researchers, studying the novel coronavirus, have found that the time between cases in a chain of transmission is less than a week, and over 10 per cent of patients are infected by someone who has the virus, but does not show symptoms yet, a finding that may help public health officials contain the pandemic.

The study, published in the journal Emerging Infectious Diseases, estimated what's called the serial interval of the coronavirus by measuring the time it takes for symptoms to appear in two people with the virus -- the person who infects another, and the infected second person.

According to the researchers, including those from the University of Texas at Austin, the average serial interval for the novel coronavirus in China was approximately four days.

They said the speed of an epidemic depends on two things -- how many people each case infects, and how long it takes cases to spread.

The first quantity, the scientists said, is called the reproduction number, and the second is the serial interval.

Due to the short serial interval of the disease caused by the coronavirus -- COVID-19 -- they said, emerging outbreaks will grow quickly, and could be difficult to stop.

“Ebola, with a serial interval of several weeks, is much easier to contain than influenza, with a serial interval of only a few days,” said Lauren Ancel Meyers, study co-author from UT Austin.

Meyers explained that public health responders to Ebola outbreaks have much more time to identify and isolate cases before they infect others.

“The data suggest that this coronavirus may spread like the flu. That means we need to move quickly and aggressively to curb the emerging threat,” Meyers added.

In the study, the scientists examined more than 450 infection case reports from 93 cities in China, and found the strongest evidence yet that people without symptoms must be transmitting the virus -- known as pre-symptomatic transmission.

More than one in ten infections were from people who had the virus but did not yet feel sick, the scientists said.

While researchers across the globe had some uncertainty until now about asymptomatic transmission with the coronavirus, the new evidence could provide guidance to public health officials on how to contain the spread of the disease.

“This provides evidence that extensive control measures including isolation, quarantine, school closures, travel restrictions and cancellation of mass gatherings may be warranted,” Meyers said.

The researchers cautioned that asymptomatic transmission makes containment more difficult.

With hundreds of new cases emerging around the world every day, the scientists said, the data may offer a different picture over time.

They said infection case reports are based on people's memories of where they went and whom they had contact with, and if health officials move quickly to isolate patients, that may also skew the data.

“Our findings are corroborated by instances of silent transmission and rising case counts in hundreds of cities worldwide. This tells us that COVID-19 outbreaks can be elusive and require extreme measures,” Meyers said.

Islamabad, May 13 : The number of confirmed COVID-19 cases in Pakistan rose to 34,370 on Wednesday after new infections were confirmed in the country.

As per province-wise breakup of the total tally cited by Radio Pakistan, so far 13,225 cases have been registered in Punjab, 12,610 in Sindh, 5,021 in Khyber Pakhtunkhwa, 2,158 in Balochistan, 759 in Islamabad, 475 in Gilgit Baltistan and 88 in Pakistan-occupied Kashmir.

As many as 2,255 cases positive were confirmed, while 31 deaths reported during the last 24 hours.

At least 737 patients have died so far while 8,812 stand recovered, the media reported further.

The Seattle City Council, one of the most powerful city councils in the U.S., on Monday unanimously passed a resolution condemning India’s recently-enacted Citizenship Amendment Act (CAA) and the National Register of Citizens (NRC).

Reaffirming Seattle as a welcoming city and expressing solidarity with the city’s South Asian community regardless of religion and caste, the resolution “resolves that the Seattle City Council opposes the National Register of Citizens and the Citizenship Amendment Act in India, and finds these policies to be discriminatory to Muslims, oppressed castes, women, indigenous, and LGBT people“.

Introduced by Indian American City Council member Kshama Sawant, the resolution urges the Parliament of India to uphold the Indian Constitution by repealing the CAA, and to stop the National Register of Citizens, and take steps towards helping refugees by ratifying various UN treaties on refugees.

“Seattle City’s decision to condemn CAA should be a message to all who wish to undermine pluralism and religious freedom. They cannot peddle in hate and bigotry, and expect to have international acceptability at the same time,” said Ahsan Khan, president of Indian American Muslim Council.

Thenmozhi Soundararajan of Equality Labs, which organised the community in support of the resolution, welcomed its passage. “We are proud of the Seattle City Council for standing on the right side of history today. Seattle is leading the moral consensus in the global outcry against the CAA, she said.

Soundararajan said that thousands of organizers across the country have called, e-mailed, and visited Seattle City Council members to amplify this resolution, and it sets an example to cities across the United States.

“At a time when members of the Indian ruling party sided Trump, the Muslim ban, and his war on immigrants as justification for targeting hundreds of millions of Indian minorities, Americans have a unique responsibility to stand up and speak about this human rights crisis. We are glad that Seattle is leading the way on this,” she said.
