COVID-19: From Exposure to Feeling Better


COVID-19: From Exposure to Feeling Better

We get a lot of questions from people about COVID-19, like what should I do if I get exposed? How long should I stay home? This video answers those questions.

This video was created May 2020 and reflects the public health guidance for COVID-19 at that time. For the most recent information please visit the Centers for Disease Control at

How Long Are You Contagious with COVID-19? | UC San Diego Health

How long is COVID19 contagious? And what should you do if you think you’ve been exposed? In this video, learn more about the CDC recommendations on self-isolation following possible COVID-19 exposure or symptoms.

All patients should follow their doctor’s recommendations for accessing care and leaving isolation. If you feel sick, unless it’s an emergency, try to call ahead so the doctor can direct you to the right place for care and possible testing.

This video was filmed on April 16, 2020. As doctors and scientists work quickly to figure out the best ways to fight COVID19, this information may become out of date. For the most up to date information and recommendations, please visit the CDC’s website,

UC San Diego Health was the first health system in the region to treat patients with COVID-19. Like hospital systems elsewhere, we have seen an increase in patients who are in need of specialized care during the COVID-19 (novel coronavirus) pandemic. We are caring for these patients at our Hillcrest and La Jolla locations in San Diego County and are well-prepared to treat more as needed. And we are embracing new ways, including telehealth, to continue seeing our other patients to keep them healthy. Get updates for UC San Diego Health patients and visitors here:

Recognizing Day to Day Signs and Symptoms of Coronavirus

Before proceeding, please note that this general overview is compiled for initial self-assessment only and may vary for each individual. If you're not feeling well, you should immediately consult a medical practitioner to have an accurate diagnosis and proper treatment of COVID-19.
The typical daily symptoms are concluded from the study of 138 patients at Zhongnan Hospital of Wuhan University and another study involving 135 patients from Jinyintan Hospital and 56 patients from Wuhan Pulmonary Hospital.
These symptoms are broken down into:
The beginning symptoms are similar to the common cold with a mild sore throat and neither having a fever nor feeling tired. Patients can still consume food and drink as usual.
The patient's throats start to feel a bit painful. Body temperature reads at around 36.5° celsius. Although it's uncommon, other symptoms like mild nausea, vomiting or mild diarrhea are possible to set in.
Throat pain becomes more serious. Other symptoms like feeling weak and joint pain start to manifest. The patient may show a temperature reading between 36.5° to 37° celsius.
DAY 5 TO 6
Mild fever starts. The patients show a temperature reading above 37.2° celsius. The second most common symptom, dry cough, also appears. Dyspnea or breathing difficulty may occur occasionally. Most patients in this stage are easily feeling tired. Other symptoms remain about the same. These four symptoms are among the top five key indications of COVID-19 according to the final report of the initial outbreak conducted by the joint mission of China and WHO.
The patients that haven't started recovering by day 7 get more serious coughs and breathing difficulty. Fever can get higher up to 38° celsius. Patients may develop further headache and body pain or worsening diarrhea if there’s any. Many patients are admitted to the hospital at this stage.
DAY 8 TO 9
On the 8th day, the symptoms are likely to be worsened for the patient who has coexisting medical conditions. Severe shortness of breath becomes more frequent. Temperature reading goes well above 38°. In one of the studies, day 9 is the average time when Sepsis starts to affect 40% of the patients.
DAY 10 TO 11
Doctors are ordering imaging tests like chest x-ray to capture the severity of respiratory distress in patients. Patients are having loss of appetite and may be facing abdominal pain. The condition also needs immediate treatment in ICU.
DAY 12 TO 14
For the survivors, the symptoms can be well-managed at this point. Fever tends to get better and breathing difficulties may start to cease on day 13. But Some patients may still be affected by mild cough even after hospital discharge.
DAY 15 TO 16
Day 15 is the opposite condition for the rest of the minority patients . The fragile group must prepare for the possibility of acute cardiac injury or kidney injury.
DAY 17 TO 19
COVID-19 fatality cases happen at around day 18. Before the time, vulnerable patients may develop a secondary infection caused by a new pathogen in the lower respiratory tract. The severe condition may then lead to a blood coagulation and ischemia.
DAY 20 TO 22
The surviving patients are recovered completely from the disease and are discharged from the hospital.

Tracking disease progression of COVID-19

Let's take a look at the common three stage progression of disease with COVID-19 — the viral response phase, the pulmonary phase, and the hyper inflammation phase.
Within those stages, we also review how the infection starts, what happens after the virus is transmitted and enters the patient's body, hospitalization needs, and briefly the recovery.

CDC shortens quarantine for people exposed to Covid-19

Dr. Carlos Del Rio, Emory School of Medicine executive associate dean, suggests day 1 to 6 to quarantine and masking, but if the patient tests negative on day 7 to end the quarantine. This could reduce the strain on health workers, he says. Meg Tirrell joins Shep Smith to discuss what the Covid-19 test turnaround times are across the U.S., as well as new CDC recommendations for quarantining. For access to live and exclusive video from CNBC subscribe to CNBC PRO:

The U.S. Centers for Disease Control and Prevention is considering shortening its recommended two-week quarantine period for people who have come in contact with people who have it — a change welcomed by some medical experts who say the relaxed guidelines would be easier for people to follow.

Current CDC guidelines recommend that anyone exposed to a person with the coronavirus quarantine at home for 14 days, even if they test negative for the virus. Scientists say that helps prevent further spread of the disease before they start showing symptoms or from those who don’t develop any symptoms.

However, CDC Director Robert Redfield said in late October that those guidelines were made when diagnostic testing wasn’t as readily available as it is today. At the time, Redfield said the agency was trying to determine whether a quarantine period could be shortened to as little as seven days with a negative Covid-19 test.

“It’s data driven, it’s under evaluation, obviously we don’t want people to be quarantined for 14 days unnecessarily,” Redfield said during an Oct. 21 press briefing at the CDC’s headquarters in Atlanta.

Dr. Henry Walke, the CDC’s incident manager for Covid-19 response, said the agency is now finalizing those new guidelines to recommend a quarantine period for seven to 10 days with a negative Covid-19 test, according to The Wall Street Journal. Agency officials are still determining the exact length of the quarantine and what type of test would be needed to end it, the Journal reported on Tuesday.

“CDC is always reviewing its guidance and recommendations in the light of new understandings of the virus that causes COVID-19, and will announce such changes when appropriate,” CDC spokesperson Belsie Gonzalez told CNBC on Wednesday.

Adm. Brett Giroir, assistant secretary of health who leads the federal government’s testing efforts as part of the White House coronavirus task force, said during a press call on Tuesday that there’s beginning to be “a preponderance of evidence that a shorter quarantine complemented by a test might be able to shorten that quarantine period from 14 days” to a shorter period.

“We are actively working on that type of guidance right now, reviewing the evidence, but we want to make absolutely sure,” Giroir told reporters. “These kind of recommendations aren’t willy-nilly. They’re worked on with a variety of experts.”

‘Should have done this sooner’

The shorter quarantine period could make it easier for people to follow the CDC’s recommendations since most people were likely shortening the two-week period on their own, Dr. Scott Gottlieb, the former Food and Drug Commissioner, said on Wednesday.

For people who have Covid-19 but are asymptomatic, meaning they never develop symptoms, chances are they will no longer be very contagious after seven to 10 days, Gottlieb said. The number of people who will contract the infection two weeks after their exposure is also “very small,” he said.

“I mean, frankly, we probably should have done this sooner,” Gottlieb told CNBC’s “Squawk Box.” “Asking people to quarantine for a full two weeks, to self-isolate for a full two weeks because of an exposure is just going to drive people not to comply with the rules. We’re better off doing something that’s practical.”

COVID-19 Lingering Symptoms: How Long Do Symptoms Last Even After Clearing The Virus?

WhiteBoard style discussion on a Research Letter published in JAMA looking at over 100 individuals who had cleared and healed from COVID-19. The authors established an outpatient clinic to care specifically for patients that had COVID-19. They found that a large percentage of these patients had lingering symptoms that persisted for weeks and weeks after clearing the infection. Check out the video for all the details!

WATCH: What to do when exposed to COVID-19, but aren’t showing symptoms

A consistent anxiety surrounding the coronavirus pandemic is what to do if you think you’re asymptomatic. Dr. Joshua Sharfstein, vice dean at Johns Hopkins Bloomberg School of Public Health and former FDA deputy commissioner, discusses the steps to take in this period of uncertainty. He notes that it is important to self-quarantine for the necessary 2 week period, even if you don't know whether you have it for sure, if you have reason to believe that you've been exposed. Sharfstein spoke with PBS NewsHour's William Brangham on May 13 about testing for coronavirus in the United States.

When can I return to work after being sick with COVID-19?

You are sick with COVID-19 symptoms but have NOT been tested for COVID-19. OR You are sick and your healthcare provider told you that you have COVID-19 based on a lab test or symptoms.

If you are sick with COVID-19 symptoms - such as fever, cough, shortness of breath, chills, headache, muscle pain, sore throat, or loss of taste or smell, but have not been tested for COVID-19 or you are sick and your doctor or local clinic told you that you have COVID-19 based on a lab test or symptoms.

Stay at home and separate yourself from others in your household. Do not share anything like utensils, or phones.

Stay at home until all three of these things are true: 1. Your symptoms, like cough or shortness of breath, have improved. 2. It’s been at least 10 days since your symptoms started. 3. You’ve had 24 hours with no fever without fever reducing medicine. Stay home for the amount of time that is the longest.

For example, your symptoms start on a Tuesday. Your temperature goes down without fever reducing medicine on the following Sunday. After 24 hours of no fever, you could return to work on Tuesday. You’ve stayed home a total of 13 full days.

One more example. Your symptoms start on Sunday. Your temperature goes down without fever reducing medicine on Thursday. After 24 hours of no fever, you’ve stayed at home for five days. Since the minimum number of days you need to stay home is 10 full days, you can return to work on Thursday.

When you return to work, stay 6 feet away from co-workers and visitors if possible and wear a mask. Check your local and workplace guidance about masks when returning to work. If you work in health care or still aren’t feeling well enough to work, talk to your employer.

COVID 19: Lingering and Chronic Symptoms After Recovery from Coronavirus Infection

This video was made in August 2020 and is only up to date till then!

There is much to learn still about COVID.
We have seen a wide range of infections - from the asymptomatic to the critically ill.
One thing we have noticed in several patients who have had COVID-19 and recovered, is several ongoing lingering symptoms. So called long haulers.
This seems to happen to some, but not all. Including those sick enough to be in the ICU, and even those not as sick. The cause and mechanism of this is still unclear, but it is a real phenomenon.
However it is important to pay attention to these symptoms, as they certainly impact quality of life.
I discuss this more in today's video.

COVID-19 Update 18: When are patients really infectious?

Individuals are infectious with COVID-19 when they're shedding the virus, which means that the virus replicates in the cells of their upper or lower respiratory tract. In this video, we will examine published articles discussing viral shedding, the incubation period (mean incubation period was 5.2 days) and the serial interval, by examining the results of 77 COVID-19 transmission pairs.

The study found that infectiousness starts 2.3 days before symptom onset. That patients are most infectious 0.7 days before symptom onset.They also found that 44% of infectiousness or infections occurred in the pre-symptomatic phase making it difficult to track.
