But this strain decreased “after early January 2020. “Human intervention may have placed more severe selective pressure on the L type, which might be more aggressive and spread more quickly. On the other hand, the S type, which is evolutionarily older and less aggressive, might have increased in relative frequency due to relatively weaker selective pressure,” they noted.
cdc website - The researchers found that second strain was likely caused by a mutation of the “ancestral version,” or type S in this case.

cdc website, Five deaths connected to the coronavirus came from a long-term care facility in Kirkland, Washington; Dan Springer reports. As community-spread of the novel coronavirus is increasingly recognized, many health care providers all over the country will be encountering patients, in all care settings, who may be infected. While many encounters may occur with the appropriate personal protective equipment (PPE) donned, as cases increase there will increasingly be situations in which health care providers may be exposed without full PPE.
cdc website - Currently, these unprotected encounters are being managed by having health care providers be quarantined for the 14-day incubation period of the virus. If this policy continues it will be disastrous and further cripple what will already be an over-extended health care system coping with a surge of patients. This approach is not sustainable. Public health officials will continue to find cases as they ramp up testing and additional transmission will occur in communities. It is likely that we will soon reach a point where most health care providers encounter known COVID-19 cases. Some fraction of these encounters may occur without the full use of PPE. We cannot establish a precedent that requires health care workers with no signs of infection to stay out of work, lest we find ourselves without enough staff to treat infected people.

While we must do the utmost to ensure that health care workers have the PPE they need to protect themselves while evaluating and treating patients, it is crucial that policies regarding health care providers are guided by sound science keeping in mind the full context of this pandemic.
