NASA proposes 'Ice Home' design for future Mars explorers

Islamabad, May 9: A female doctor posted at Pakistan Institute of Medical Sciences (Pims) Mother and Child Hospital (MCH), who was tested Covid-19 positive, has exposed Pakistan's mismanagement in handling the patients affected with the deadly virus.

Identified herself as Dr. Sharbat, she made a video of herself locked in an isolated room when the authorities failed to provide any medical assistance to her.

According to Pakistani media, the Pakistan Institute of Medical Sciences (Pims) Mother and Child Hospital (MCH) and the operating theatre in the Children's Hospital were sealed on Tuesday after 15 people from both facilities were diagnosed with Covid-19.

Dr. Sharbat said that despite having Covid-19 symptoms after her colleague doctor was tested positive, she was forced to perform duty by the hospital authorities.

After she tested positive, Dr. Sharbat has isolated herself in a room and has requested the hospital authorities to provide her a bed in the hospital.

She said, "I am isolated in a small room. There is no toilet and other facilities at this place. I have requested the authorities several times to provide me proper bed because I cannot go home as my son and father is there. I have no other place to go. Its been several hours now and the administration is busy doing meetings. They have no idea about my location. I have called the concerned officials several times and requested for a room in the hospital, but they said that they are looking for it. This is the kind of arrangements we have that a doctor, who was serving the patients, is not able to get proper care".

Dr Sharbat said that she is feeling depressed after seeing the response of authorities tackling with Covid-19 crisis in the country.

She added, "It is unfortunate that the government salutes [health professionals] but is not willing to provide isolation rooms."

Pakistan's position in the global ranking in respect of Covid-19 dropped from 24th to 22nd after the number of positive cases increased to 26,806 (till May 08) with the addition of 1,791 new cases.

However, the National Coordination Committee (NCC), chaired by Prime Minister Imran Khan, had decided to substantially ease the lockdown from Saturday after detailed deliberations and consultations with the provinces.

Tokyo, Mar 4: Takeda Pharmaceutical Co said on Wednesday it was developing a drug to treat COVID-19, the flu-like illness that has struck more than 90,000 people worldwide and killed over 3,000.

The Japanese drugmaker is working on a plasma-derived therapy to treat high-risk individuals infected with the new coronavirus and will share its plans with members of the U.S. Congress on Wednesday, it said in a statement.

Takeda is also studying whether its currently marketed and pipeline products may be effective treatments for infected patients.

"We will do all that we can to address the novel coronavirus threat...(and) are hopeful that we can expand the treatment options," Rajeev Venkayya, president of Takeda's vaccine business, said in the statement.

Takeda said it was in talks with various health and regulatory agencies and healthcare partners in the United States, Asia and Europe to move forward its research into the drug.

Its research requires access to the blood of people who have recovered from the respiratory disease or who have been vaccinated, once a vaccine is developed, Takeda said.

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.
