The disease is caused by a novel coronavirus, 우리카지노 officially known as SARS-CoV-2, which has now infected over 60,000 people and claimed more than 1,350 lives. On Thursday, the CDC confirmed a 15th case in the US under quarantine at Joint Base San Antonio-Lackland in Texas.
The illness was first reported to the World Health Organization on New Year’s Eve and in the intervening weeks was linked to a family of viruses known as coronaviruses, the same family responsible for the diseases SARS and MERS, as well as some cases of the common cold. On Feb. 11, the WHO and other organizations agreed on the name COVID-19 for the illness.
On Feb. 12, Chinese health authorities reported a jump in the amount of cases and deaths in Hubei, the epicenter of the outbreak. Over 13,300 new cases were recorded in Hubei alone, an increase of 700% over the previous day. Chinese authorities had adopted a new clinical method for confirming cases Wednesday, which sees them add “clinically diagnosed cases” to the count, 우리카지노계열 which could help patients receive treatment sooner, according to CNN.
A special WHO committee declared a public health emergency of international concern on Jan. 30, 우리카지노 citing “the potential for the virus to spread to countries with weaker health systems.” Human-to-human transmission has been confirmed outside China, including in the US, and authorities around the world have limited travel and enforced quarantines to guard against the spread.
Barcelona’s Mobile World Congress, the world’s largest phone trade show, took the unprecedented step of cancelling the entire show which routinely attracts 100,000 visitors from across the world. A number of companies, including LG, Amazon, 우리카지노계열 Sony and Nvidia, had previously stated they wouldn’t be attending this year’s show, 우리카지노계열 citing coronavirus concerns.

Coronaviruses belong to a family known as Coronaviridae, and under an electron microscope they look like spiked rings. They’re named for these spikes, which form a halo or “crown” (corona is Latin for crown) around their viral envelope.
Coronaviruses contain a single strand of RNA within the envelope and, as a virus, can’t reproduce without getting inside living cells and hijacking their machinery. The spikes on the viral envelope help coronaviruses bind to cells, which gives them a way in, like blasting the door open with C4. Once inside, they turn the cell into a virus factory, using its molecular conveyor belt to produce more viruses, which are then shipped out of the cell. The virus progeny infect other cells and the cycle starts anew.
