How does a vaccination for dogs work? One of the 195 Americans evacuated from Wuhan, China, was placed under mandatory quarantine after trying to leave the facility where the evacuees were supposed to stay for 72 hours of voluntary monitoring, Reuters reported Thursday, citing public health officials.
On Thursday evening, after a meeting of an emergency committee responding to the outbreak, the World Health Organization (WHO) published an estimated R0 of 1.4 to 2.5. Other teams have since come up with slightly higher values 1 , 2 These estimates are similar to the R0 of SARS during the early stages of the 2002-03 outbreak, and of the novel strain of H1N1 influenza that caused a pandemic in 2009.



So when an infected person coughs or sneezes, they let out a spray, and if these droplets reach the nose, eyes, or mouth of another person, they can pass on the virus, said Jennifer Nuzzo, an infectious disease expert and senior scholar at the Johns Hopkins Center for Health Security.
In China, sick people have been infecting others through person-to-person transmission since the start of January, and the WHO has reported that there have been sustained chains of comunità cinese people passing the virus along for at least four generations : one person got sick (probably from an animal), passed the virus to another person, who passed it to another person.

In addition, diagnosing 2019-nCoV requires specialized equipment and personnel that may be difficult to scale to test the thousands of people who need it. If people without symptoms are capable of transmitting the virus, it would be impossible to test entire city populations.
25 with fever, cough, and sore throat, developed severe pneumonia but in the last few days was stable and showed signs of improvement; however, the condition of the patient deteriorated within his last 24 hours resulting in his demise." reported the Philippine Department of Health.
But three times so far in the 21st century, novel coronaviruses have emerged that could potentially cause a deadly pandemic—SARS (severe acute respiratory syndrome) in 2003, MERS (Middle East respiratory syndrome) in 2012, and now 2019-nCoV emanating from Wuhan, China.

They also highlight that the models assume travel behaviour was not affected by disease status and that all infections eventually have symptoms - so it is possible that milder cases have gone undetected which could underestimate the size of the outbreak.
A system could immediately be established to take test samples from patients with concerning symptoms who are not severely ill and then send them home with protective respirator masks , instructions on hand-washing to prevent the further spread of the disease, and orders to remain at home until the test results come back.

He said the new strain of virus remained "moderately transmissible" and had a demonstrated mortality rate of around 2% at present — much lower than other disease outbreaks such as Ebola, which had a 70% mortality rate, or even the related SARS coronavirus that had a 10% mortality rate.
