UK Prime Minister Boris Johnson tests positive for deadly coronavirus

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.”

May 20: The novel coronavirus is behaving differently in patients in northeast China who have contracted it recently compared with early cases, indicating it is changing as it spreads, a prominent doctor said.

China, which has largely brought the virus under control, has found new clusters of infections in the northeastern border provinces of Jilin and Heilongjiang in recent weeks, raising concern about a second wave.

Qiu Haibo, an expert in critical care medicine who is part of a National Health Commission expert group, said the incubation period of the virus in patients in the northeast was longer than that of patients in Wuhan, the central city, where the virus emerged late last year.

"This causes a problem, as they don't have any symptoms. So when they gather with their families they don't care about this issue and we see family cluster infections," Qiu told state broadcaster CCTV in a programme broadcast late on Tuesday.

Patients in the northeastern clusters were also carrying the virus for longer than earlier cases in Wuhan, and they were taking longer to recover, as defined by a negative nucleic acid test, he said.

Patients in the northeast also rarely exhibited fever and tended to suffer damage to the lungs rather than across multiple organs, he said.

He said the virus found in the northeastern clusters was probably imported from abroad, which could account for the differences.

He did not say where he though they might have come from but both Jilin and Heilongjiang border Russia.

China reported five new coronavirus cases on Wednesday, down from six a day earlier.

Four of the new cases were local transmissions and one was imported by a traveller coming from abroad, the commission said in a statement, compared with three imported cases reported the previous day.

China's total number of coronavirus infections stands at 82,965, while the death toll 4,634. 

May 6: In a first, a Pakistani Hindu youth has become the first person from the minority community to join the Pakistan Air Force.

Rahul Dev has been recruited as a General Duty Pilot Officer, the Pakistan Air Force (PAF) said in a tweet.

Dev hails from Tharparkar district of Sindh province.

Sharing the picture of the young man, the PAF recently tweeted, "Good news during #COVID19 tense situation. Thar rocked again...Congratulations #RahulDev who hails from very remote village of Tharparkar has been selected as GD Pilot in #PAF."

Though Dev's exact age is not known, those inducted in PAF at his level are often around 20.

The official Radio Pakistan on Wednesday said it is "for the first time in Pakistan's history" that a Hindu youth has been recruited as a general duty pilot officer in PAF.

The Express Tribune in a report published on Wednesday said the induction showed that the PAF was breaking barriers.

Last year, Kainat Junaid became the first woman from Khyber-Pakthunkhwa province to have been selected for fighter pilot training.

Junaid not only secured the top position in PAF's test for General Duty Pilot, but also became Pakistan’s first female fighter pilot to serve the country alongside her father.

Her father Ahmed Junaid is a Squadron Leader in the PAF.
