At least 84 dead in 'terrorist' Nice truck attack

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.”

Islamabad, Jun 10: The World Health Organization has told Pakistan it should implement "intermittent" lockdowns to counter a surge in coronavirus infections that has come as the country loosens restrictions, officials said.

Since the start of Pakistan's outbreak in March, Prime Minister Imran Khan opposed a nationwide lockdown of the sort seen elsewhere, arguing the impoverished country could not afford it.

Instead, Pakistan's four provinces ordered a patchwork of closures, but last week Khan said most of these restrictions would be lifted.

Health officials on Wednesday declared a record number of new cases in the past 24 hours. The country has now confirmed a total of more than 113,000 cases and 2,200 deaths -- though with testing still limited, real rates are thought to be much higher.

"As of today, Pakistan does not meet any of the pre-requisite conditions for opening the lockdown", the WHO said in a letter confirmed by Pakistan officials on Tuesday.

Many people have not adopted behavioural changes such as social distancing and frequent hand-washing, meaning "difficult" decisions will be required including "intermittent lockdowns" in targeted areas, the letter states.

Some 25 percent of tests in Pakistan come back positive for COVID-19, the WHO said, indicating high levels of infection in the general population.

The health body recommended an intermittent lockdown cycle of two weeks on, two weeks off.

Responding to the WHO's letter, Zafar Mirza, the prime minister's special advisor for health, said the country had "consciously but gradually" eased lockdowns while enforcing guidelines in shops, mosques and public transport.

"We have to make tough policy choices to strike a balance between lives and livelihoods," Mirza said Wednesday.

Punjab's provincial health minister Yasmin Rashid, who received the WHO's letter, said the provincial government had already given "orders to take strict action against those violating" virus guidelines.

Hospitals across Pakistan say they are at or near capacity, and some are turning COVID-19 patients away.

WHO Director-General Tedros Adhanom Ghebreyesus said Monday that 136,000 cases had been reported in the previous 24 hours, "the most in a single day so far", with the majority of them in South Asia and the Americas.

The death toll in China's coronavirus rose sharply to 425 with 64 deaths on Monday alone while 3,235 new confirmed cases were reported, taking the number of those infected with the deadly disease to 20,438, Chinese health authorities said on Tuesday.

The 64 people who died on Monday were all from the Hubei province, the epicentre of the virus, China's National Health Commission said.

Also, 3,235 new confirmed cases of novel coronavirus infection were reported, a big increase in a day.

Another 5,072 new suspected cases were reported on Monday, said the commission, adding that 492 patients became seriously ill.

The commission said that 2,788 patients remained in severe condition and 23,214 people were suspected of being infected with the virus, a pointer that it is increasingly turning virulent.

The overall confirmed cases on the Chinese mainland had reached 20,438 by the end of Monday, the commission said, noting that a total of 425 people had died of the disease.

A total of 632 people had been discharged from hospital after recovery, state-run Xinhua news agency reported As the virus spreads from human to human, 221,015 close contacts had been traced, with 171,329 others still under medical observation.

By the end of Monday, 15 confirmed cases had been reported in Hong Kong, eight in the Macao and 10 in Taiwan.

The Philippines reported the first overseas death from the virus on Sunday while 148 cases have been reported from abroad.

India has reported three cases of the coronavirus. All the three patients from Kerala recently returned from the affected Wuhan city.

Currently, 647 Indians and seven Maldivians who have been evacuated from Wuhan and Hubei are in 14-day quarantine at a medical camp in Manesar, near Delhi.

As the virus continued to spread at an alarming rate, Chinese President Xi Jinping on Monday warned officials of punishment if they shirked responsibility in tackling the virus outbreak.

On Monday, China has opened a 1,000-bed hospital built in record nine days in Wuhan city and started trials for new drug to contain the virus and is set to open another 1,300 bed hospital next to it on Wednesday.

The ruling Communist Party of China on Monday held its political bureau meeting presided by President Xi to review the steps being taken on various fronts to halt the spread of the deadly virus.

The outcome of the epidemic prevention and control directly affects people's lives and health, the overall economic and social stability and the country's opening-up, Xi said.

"Those who disobey the unified command or shirk off responsibilities will be punished," Xi was quoted as saying by the state-run Xinhua news agency.

Xi said that the party and government leaders supervising them would also be held accountable in severe cases.

Chinese armament firms, including those building aircraft carrier and military aircraft, have postponed planned work in order to concentrate on controlling the risk of coronavirus, state-run Global Times reported.

Noted Chinese health expert Zhong Nanshan has said that based on the fresh evidence, the novel coronavirus, which is spreading rapidly in China and the world, may reach its peak in the next 10 to 14 days, contrary to earlier estimates of climaxing sooner.

This means that the cases would drastically increase in the next two weeks before slowing down.

Also, China has begun clinical trials to test a drug to treat the patients of the coronavirus which till now has no cure.

Currently, patients are being treated with a combination of antivirals and other measures, as scientists race to find a vaccine.

Some reports said drugs to treat HIV too was being tried to treat the patients.

The experimental antiviral drug, Remdesivir, to be tested in field trials is developed by US-based Gilead Sciences. It is aimed at treating infectious diseases such as Ebola and SARS, South China Morning Post reported.

It was given to the first US patient last week - a 35-year-old man whose condition appeared to improve within a day, it said.
