WHO: It would be the “first pandemic in history that could be controlled.”   It is an “uneven epidemic at the global level” because 93 percent of cases are from four countries. WHO guidelines define a pandemic as a worldwide spread of a new disease. He said there are still things countries can do to slow down the virus and prevent infections. We are not at the mercy of this virus. Countries should continue finding and testing cases, isolating patients and following their contacts to stop the disease from spreading globally, he said.

Some patients could show COVID-19 symptoms after quarantine

Although a 14-day quarantine after exposure to SARS COV-2 is "well supported" by evidence, some infected individuals will not become symptomatic until after that period, according to authors of a recent analysis published in Annals of Internal Medicine.

Most will develop symptoms by day 12 of the infection, which is within the 14-day period of active monitoring currently recommended by the Centers for Disease Control and Prevention. However, an estimated 101 out of 10,000 cases could become symptomatic after the end of that 14-day monitoring period.

The analysis, based on 181 confirmed cases of coronavirus disease 2019 (COVID-19) saw incubation period of 5.1 days. Symptoms developed within 11.5 days for 97.5% of patients in the study.


Of the 70,000 cases, WHO scientists looked at, only about 2% were in people younger than 19. The odds of developing COVID-19 increase with age, starting at age 60. It’s especially lethal for people over 80.

Starting at age 60, there is an increasing risk of disease and the risk increases with age.

1.     People with diabetes, heart disease, lung disease and other serious underlying conditions are more likely to develop “serious outcomes, including death,”
2.      CDC is recommending people with underlying conditions or who are over 60 to stock up on medications, household items and groceries to stay at home “for a period of time,”
3.      The U.S. government recommended travelers with underlying health conditions avoid taking any cruises anywhere in the world.
4.     We also recommend people at higher risk avoid non-essential travel, such as long plane trips.
5.      People at higher risk avoid crowds, touching “high-touch” surfaces in public areas and close contact with people who are sick.
6.      In South Korea, no one under the age of 30 has died and in Japan, no one under 50 has died
