How long does it take for the coronavirus to recover? Different countries have different answers

- May 08, 2020-

In Denver, the United States, Rachel Wall described the symptoms of coughing, extreme fatigue, and fever. The doctor asked her to isolate herself at home for 10 days until she had no symptoms of fever for 72 consecutive hours. In Cincinnati, the doctor of Elizabeth Edwards advised her to stay at home for 14 days until there were no symptoms for three consecutive days.

In the Netherlands, Kevin Toms doctors also gave him instructions to stay in house for 14 days. In Australia, Amy McKenzie's home isolation may be longer. She needs to test negative for two consecutive times in order to prove that she no longer carries the virus; and only after the symptoms disappear, she has Eligibility to be tested.

When can patients recovering from the new coronavirus safely return to life before the epidemic to some extent? Due to insufficient data on the course of New Coronary Pneumonia, and people's understanding of New Coronavirus is constantly refreshing, there are huge differences in the guiding principles given by different countries in the world, even in many countries.

In addition, some guiding principles vary depending on the severity and type of specific cases, leading to further uncertainty. The Australian Government has developed three sets of guidelines, one for mildly isolated patients at home, one for inpatients, and one for medical workers.

This difference in policies confuses patients. They are at a loss and do not know when they will be cured. They said this further deepened their anxiety.

"We are in an unknown field. We really don't have an answer. That's the problem." Said John Gumina, director of the Department of Family Medicine at Jersey Shore University Medical Center in Jersey. His location in New Jersey is the most severely affected state in the United States after New York. Gumina advised patients to be quarantined for 14 days, but he admitted that sometimes even if it were, the patient would feel uncomfortable.

A pulse oximeter is a device that can measure blood oxygen saturation, which can help patients judge their condition and relieve stress.

At present, scientists have not fully figured out when patients begin to be contagious, or when they are no longer contagious.

Most new crown prevention guidelines focus on symptoms, but some patients have extremely mild symptoms that may be difficult to detect. Robert Redfield, director of the Centers for Disease Control and Prevention, said recently that the proportion of asymptomatic infections in the United States may be as high as 25%. Experts say it is unclear whether they are contagious. Some cases in China and the United States have shown that asymptomatic patients may not test positive until nearly a month after the initial infection.

The US Centers for Disease Control and Prevention (CDC) guidelines say that if patients with new coronary pneumonia meet the following three criteria, they do not need to be isolated at home:

1. Without taking antipyretics, no fever for at least 72 hours;

2. Respiratory symptoms such as cough and shortness of breath have improved;

3. At least seven days since the symptoms first appeared.

The CDC emphasized that whether to stop home segregation should be decided in consultation with medical institutions, state and local health departments according to local conditions.

"The current best solution may change every day," said Aditya Shah, an infectious disease doctor at Mayo Clinic in Rochester, Minnesota.
