The name coronavirus is derived from the Latin word corona meaning crown, Coronaviruses are a large family of viruses that infects the lungs

More than 300 scientists and researchers participating both in person and virtually agreed on a set of global research priorities.

Here's the timeline of how the Coronavirus outbreak evolved from Wuhan city in China and spreading its tentacles across the world.

Every country is trying to combat with COVID-19 according to its resources. Politicians, doctors, scientists and economy experts are trying to find a perfect mix which can work well in this situation. Some countries are acting smartly. Along with these efforts, they are also observing the conditions of other countries to improvise their policies.

A news report suggests the Department of Health and Social Care is aiming to be ready to start charging for Covid-19 tests which are currently free at the end of June. Britain has been increasingly dependent on rapid testing to try to tackle the more-transmissible Omicron variant, which has spread rapidly through the population but is less severe. The government has previously said it will end the universal free provision of easy-to-use lateral flow devices (LFDs) at a "later stage", with individuals and businesses bearing the cost. The Department of Health has declined to say what the tests cost, citing commercial contracts. One source has told the Reuters news agency they can run to £30 for a pack of seven. Free pick up from pharmacies The tests have been made freely available to order online or pick up from local pharmacies since April. The UK Health Security Agency said that between December 30 and January 5 more than 8 million LFDs were conducted, the highest weekly figure on record.

The Pharmacy Collect team is now in position to supply additional stocks of lateral flow device (LFD) test kits to pharmacies that are still experiencing higher demand, Pharmaceutical Services Negotiating Committee (PSNC) said in an update. The team has informed the negotiator that LFD orders in some locations have reduced allowing them to work with Alliance Healthcare to facilitate extra deliveries. The UK Health Security Agency (UKHSA), which is continuing to deliver LFD stocks to Alliance Healthcare for onward delivery to pharmacies, distributed over 14.5 million tests to the company last week. Community pharmacy contractors can seek up to three additional cartons of test kits by emailing the Pharmacy Collect team. This will be in addition to one carton daily order that contractors are allowed to get through Alliance Healthcare.

Lapses in strategies to tackle COVID-19 this year continue to create the perfect conditions for a deadly new variant to emerge, as parts of China witness a rise in infections, the head of the World Health Organization said on Friday (December 2). The comments by WHO Director-General Tedros Adhanom Ghebreyesus mark a change in tone just months after he said that the world has never been in a better position to end the pandemic. "We are much closer to being able to say that the emergency phase of the pandemic is over, but we're not there yet," Tedros said on Friday. The global health agency estimates that about 90% of the world's population now has some level of immunity to SARS-COV-2 either due to prior infection or vaccination. "Gaps in testing … and vaccination are continuing to create the perfect conditions for a new variant of concern to emerge that could cause significant mortality," Tedros said. COVID-19 infections are at record highs in China and have started to rise in parts of Britain after months of decline.

BioNTech and Pfizer are to start tests on humans of next-generation vaccines that protect against a wide variety of coronaviruses in the second half of the year. Their experimental work on shots that go beyond the current approach include T-cell-enhancing shots, designed to primarily protect against severe disease if the virus becomes more dangerous, and pan-coronavirus shots that protect against the broader family of viruses and its mutations. In presentation slides posted on BioNTech's website for its investor day, the German biotech firm said its aim was to "provide durable variant protection". The two companies are currently discussing with regulators enhanced versions of their established shot to better protect against the Omicron variant and its sublineages. The virus' persistent mutation into new variants that more easily evade vaccine protection, as well as waning human immune memory, have added urgency to the search by companies, governments and health bodies for more reliable tools of protection. As part of a push to further boost its infectious disease business, BioNTech said it was independently working on precision antibiotics that kill superbugs that have grown resistant to currently available anti-infectives.
