Washington, Mar 27: The United States has seen a record 18,000 new confirmed coronavirus cases and 345 deaths over the past 24 hours, according to a Johns Hopkins University tracker.
There are now 97,028 declared virus cases in the country and there have been 1,475 deaths, Johns Hopkins said.
Wuhan, Jan 20: A 45-year-old Indian woman has become the first foreigner in China to have contracted a mysterious virus, which is suspected to be Severe Acute Respiratory Syndrome (SARS)-like corona virus.
In 2002-2003, the SARS corona virus killed around 650 people in China and Hong Kong. This time, a new strain of virus with 62 cases have been reported in Wuhan and two in Shenzhen so far. 19 patients have been already cured and discharged, as per the Chinese media.
Official sources in Beijing said that the patient, Preeti Maheshwari, a school teacher at an international school, is undergoing treatment for the new strain of pneumonia outbreak, which has been spreading in two major cities of China - Wuhan and Shenzen. She has been on a ventilator in the intensive care unit.
Maheshwari was admitted to a local hospital after she seriously fell ill last Friday. Her husband, a businessman from Delhi, is allowed to visit her daily.
Following a second death due to the outbreak of the virus in Wuhan, India on Friday issued an advisory to its nationals travelling to China. Over 500 Indian medical students are studying in Wuhan.
Canadian researchers are developing a DNA vaccine for SARS-CoV-2, the coronavirus that causes COVID-19 and has currently infected nearly 5,00,000 people worldwide and crippled the global economy.
Entos Pharmaceuticals, a health-care biotechnology company headed by a University of Alberta researchers, develop new therapeutic compounds using the company's proprietary drug-delivery platform and has begun manufacturing vaccine candidates against the novel coronavirus.
"Given the urgency of the situation, we can have a lead candidate vaccine within two months. Once we have that it's a race to get it into clinical trials," said John Lewis, CEO of Entos and a Professor at the University of Alberta in Canada.
Lewis said in comparison to a traditional vaccine, DNA-based vaccines hold several advantages.
Nucleic acids are introduced directly into the patient's own cells, causing them to make pieces of the virus--tricking the immune system into mounting a response without the full virus actually being present, the researcher said.
According to the company, the approach is recognised as being easier to move into large-scale manufacturing, offers improved vaccine stability and works without needing an infectious agent.
In the current absence of a vaccine for COVID-19, several companies around the world are mounting efforts to begin similar work.
The first clinical trial using a DNA-based vaccine developed by Moderna Inc.in the US on March 13.
Their approach allows for antibodies to be made in the human trial volunteers against a specific protein on the surface of the coronavirus that lets the virus enter human cells.
The hope is that the antibodies will stop the interaction.
Though this approach is designed to be effective against COVID-19 specifically, Lewis said Entos is taking a different tack.
The company plans to use plasmid DNA to amplify the production of key coronavirus surface and structural proteins with each injection, with an eye to the bigger picture.
"Many of the structural proteins in the virus are pretty well conserved across all the coronaviruses, including SARS and MERS," said Lewis.
"We're hoping that if we express more of the structural proteins that are common to most coronaviruses, we can inhibit the current COVID-19, and also potentially protect against all coronaviruses both past and future," Lewis added.
To move the project forward quickly, the company is seeking financial support from both provincial and federal levels of government.
"We have the opportunity to save a lot of lives, and I think it's really upon us and governments to find solutions for that," Lewis said.
London, May 9: Air India's first evacuation flight from London will be taking off for Mumbai today.
The screening of passengers is underway.
"Air India's first evacuation flight from London taking off for Mumbai today at 1200. Flight is 100% booked! Shubh Yatra. Please stay in touch. GoI working to send more evacuation flights!" High Commission of India, London said in a tweet.
On Monday, India announced had that it will begin phased repatriation of its citizens stranded abroad from May 7.
The government said that Air India will operate 64 flights in the first week from May 7 to May 13 to bring back around 15,000 Indian nationals.
On day three of the 'Vande Bharat Mission', flights carrying Indians from the Gulf countries, the United Kingdom, Bangladesh and Malaysia will arrive in India.
