May 19: A Chinese laboratory has been developing a drug it believes has the power to bring the coronavirus pandemic to a halt.

The outbreak first emerged in China late last year before spreading across the world, prompting an international race to find treatments and vaccines.

A drug being tested by scientists at China's prestigious Peking University could not only shorten the recovery time for those infected, but even offer short-term immunity from the virus, researchers say.

Sunney Xie, director of the university's Beijing Advanced Innovation Center for Genomics, told AFP that the drug has been successful at the animal testing stage.

"When we injected neutralising antibodies into infected mice, after five days the viral load was reduced by a factor of 2,500," said Xie.

"That means this potential drug has (a) therapeutic effect."

The drug uses neutralising antibodies -- produced by the human immune system to prevent the virus infecting cells -- which Xie's team isolated from the blood of 60 recovered patients.

A study on the team's research, published Sunday in the scientific journal Cell, suggests that using the antibodies provides a potential "cure" for the disease and shortens recovery time.

Xie said his team had been working "day and night" searching for the antibody.

"Our expertise is single-cell genomics rather than immunology or virology. When we realised that the single-cell genomic approach can effectively find the neutralising antibody we were thrilled."

He added that the drug should be ready for use later this year and in time for any potential winter outbreak of the virus, which has infected 4.8 million people around the world and killed more than 315,000.

"Planning for the clinical trial is underway," said Xie, adding it will be carried out in Australia and other countries since cases have dwindled in China, offering fewer human guinea pigs for testing.

"The hope is these neutralised antibodies can become a specialised drug that would stop the pandemic," he said.

China already has five potential coronavirus vaccines at the human trial stage, a health official said last week.

But the World Health Organization has warned that developing a vaccine could take 12 to 18 months.

Scientists have also pointed to the potential benefits of plasma -- a blood fluid -- from recovered individuals who have developed antibodies to the virus enabling the body's defences to attack it.

More than 700 patients have received plasma therapy in China, a process which authorities said showed "very good therapeutic effects".

"However, it (plasma) is limited in supply," Xie said, noting that the 14 neutralising antibodies used in their drug could be put into mass production quickly.

Using antibodies in drug treatments is not a new approach, and it has been successful in treating several other viruses such as HIV, Ebola and Middle East Respiratory Syndrome (MERS).

Xie said his researchers had "an early start" since the outbreak started in China before spreading to other countries.

Ebola drug Remdesivir was considered a hopeful early treatment for COVID-19 -- clinical trials in the US showed it shortened the recovery time in some patients by a third -- but the difference in mortality rate was not significant.

The new drug could even offer short-term protection against the virus.

The study showed that if the neutralising antibody was injected before the mice were infected with the virus, the mice stayed free of infection and no virus was detected.

This may offer temporary protection for medical workers for a few weeks, which Xie said they are hoping to "extend to a few months".

More than 100 vaccines for COVID-19 are in the works globally, but as the process of vaccine development is more demanding, Xie is hoping that the new drug could be a faster and more efficient way to stop the global march of the coronavirus.

"We would be able to stop the pandemic with an effective drug, even without a vaccine," he said.

Beijing, Feb 3: The first batch of patients arrived on Monday at a specialised hospital built in just 10 days as part of China's intensive efforts to fight a new virus.

Huoshenshan Hospital and a second facility with 1,500 beds that's due to open this week were built by construction crews who are working around the clock in Wuhan, the city in central China where the outbreak was first detected in December.

The Wuhan treatment centres mark the second time Chinese leaders have responded to a new disease by building specialised hospitals almost overnight. As severe acute respiratory syndrome, or SARS, spread in 2003, a facility in Beijing for patients with that viral disease was constructed in a week.

The first batch of patients arrived at the Huoshenshan Hospital at 10 am on Monday, according to state media. The reports gave no details of the patients' identities or conditions.

The ruling Communist Party's military wing, the People's Liberation Army, sent 1,400 doctors, nurses and other personnel to staff the Wuhan hospital, the official Xinhua News Agency said. The government said earlier some have experience fighting SARS and other outbreaks.

Authorities have cut most road, rail and air access to Wuhan and surrounding cities, isolating some 50 million people, in efforts to contain the viral outbreak that has sickened more than 17,000 and killed more than 360 people.

The Huoshenshan Hospital was built by a 7,000-member crew of carpenters, plumbers, electricians and other specialists, according to the Xinhua News Agency.               Photos in state media showed workers in winter clothing, safety helmets and the surgical-style masks worn by millions of Chinese in an attempt to avoid contracting the virus.

About half of the two-storey, 600,000-square-foot building is isolation wards, according to the government newspaper Yangtze Daily. It has 30 intensive care units.

Doctors can talk with outside experts over a video system that links them to Beijing's PLA General Hospital, according to the Yangtze Daily. It said the system was installed in less than 12 hours by a 20-member "commando team" from Wuhan Telecom Ltd.

The building has specialised ventilation systems and double-sided cabinets that connect patient rooms to hallways and allow hospital staff to deliver supplies without entering the rooms.

The hospital received a donation of "medical robots" from a Chinese company for use in delivering medicines and carrying test samples, according to the Shanghai newspaper The Paper.

In other cities, the government has designated hospitals to handle cases of the new virus.

In Beijing, the Xiaotangshan Hospital built in 2003 for SARS is being renovated by construction workers. The government has yet to say whether it might be used for patients with the new disease.

Sao Paulo, June 20: Brazil’s government confirmed on Friday that the country has risen above 1 million confirmed coronavirus cases, second only to the United States.

The country’s health ministry said that the total now stood at 10,32,913, up more than 50,000 from Thursday. The ministry said the sharp increase was due to corrections of previous days’ underreported numbers.

Brazilian President Jair Bolsonaro still downplays the risks of the virus after nearly 50,000 deaths from COVID-19 in three months, saying the impact of social isolation measures on the economy could be worse than the disease itself.

Specialists believe the actual number of cases in Brazil could be up to seven times higher than the official statistic. Johns Hopkins University says Brazil is performing an average of 14 tests per 1,00,000 people each day, and health experts say that number is up to 20 times less than needed to track the virus.

Official data show a downward trend of the virus in Brazil’s north, including the hard-hit region of the Amazon, a plateau in cases and deaths in the countries’ biggest cities near the Atlantic coast, but a rising curve in the south.

In the Brazilian countryside, which is much less prepared to handle a crisis, the pandemic is clearly growing. Many smaller cities have weaker health care systems and basic sanitation that’s insufficient to prevent contagion.

“There is a lot of regional inequality in our public health system and a shortage of professionals in the interior,” said Miguel Lago, executive director of Brazil’s Institute for Health Policy Studies, which advises public health officials.

That creates many health care deserts, with people going long distances to get attention. When they leave the hospital, the virus can go with them.

The cattle-producing state of Mato Grosso was barely touched by the virus when it hit the nation’s biggest cities in March. Sitting far from the coast, between the Bolivian border and Brazil’s capital of Brasilia, its 33 lakh residents led a mostly normal life until May. But now its people live under lockdown and meat producers have dozens of infected workers.

In Tangará da Serra, a city of 1,03,000 people in Mato Grosso, the mayor decided Friday to forbid the sale of alcoholic drinks for two weeks as an incentive for people to stay home.

Fᢩo Junqueira said the measure was needed after a spike in COVID-19 cases that filled 80% of the city’s 54 intensive care beds. The city has had nearly 300 cases of the disease, plus three fatalities.

In Rondonópolis, only 300 miles away from Tangará da Serra and home to a thriving economy, health authorities closed the local meatpacking industry after 92 cases were confirmed there. The city of 1,44,000 inhabitants counted 21 deaths from the virus and more than 600 cases. The mayor has also decided to limit sales of alcoholic beverages.

Even regions once considered examples of successful efforts against the virus are now struggling.

Porto Alegre, home to about 14 lakh people, had success in slowing the virus’ spread over the last three months. But now its mayor is considering increasing social isolation measures after ICU occupancy in the city jumped to 80% this month.

We were already making projections for schools to come back, Mayor Nelson Marchezan Jr. told The Associated Press. Now the trend is to impose more restrictions. Outside Sao Paulo city, five regions of the state’s countryside will have to close shops starting Monday due to a rise in coronavirus cases. Governor João Doria announced the decision Friday.

Dr. Mike Ryan, the World Health Organization’s executive director, said at a news conference that Brazil needs to increase its efforts to stop the spread of infections.

“The epidemic is still quite severe in Brazil. I believe health workers are working extremely hard and under pressure to be able to deal with the number of cases that they see on a daily basis,” Dr. Ryan said.

“Certainly the rise is not as exponential as it was previously, so there are some signs that the situation is stabilising. But we’ve seen this before in other epidemics in other countries.”

Margareth Dalcolmo, a clinical researcher and professor of respiratory medicine at the state-funded Oswaldo Cruz Foundation in Rio de Janeiro, believes the reopening in major cities and the virus traveling by road into Brazil’s heartland will keep the pressure on the country’s health system.

“The risk in the interior now is very big,” she said. “Our health system just can’t solve the most serious cases of COVID in many places of the countryside.”
