What should the level of concern be right now for people in Missouri and Southern Illinois?

The risk to the general public is very low, but the situation changes day by day and sort of hour by hour almost. So, it is appropriate for people to be aware that this virus is out there.

If you catch COVID-19, would you have more immunity to it after, like the flu?

Typically, if coronavirus acts like any other virus — which there is no reason to believe that it wouldn't — then your body does build up immunity to the virus.

What are the symptoms, and when should I go to the doctor?

If you are older or have chronic conditions like Emphysema or something like that, then it's more important for you to get in contact with your physician or medical care provider sooner.

How will our local health care department handle Washington University students coming back from Italy or other people coming back from highly infected areas?

Unless they're symptomatic, it's usually sort of a self-quarantine for 14 days and that's thought to be enough time to cover the incubation period if they were going to develop an illness. And then, the health department will sometimes make contact with them to do temperature checks and ask, 'How are you feeling?' things like that.

Below are more questions St. Louisans are asking. These were researched and written based on information 5 On Your Side gathered.

How long does COVID-19 survive on surfaces?

According to the CDC, it is possible to contract COVID-19 by touching a surface or object that has the virus on it, then touching one’s mouth, nose or possibly eyes. However, experts say this is not the main way the virus spreads.

CDC officials say COVID-19 generally has a poor survivability on surfaces and poses a low risk from one person to another. A study by the Journal of Hospital Infection found other strains of coronavirus have the potential to remain on metal, glass and plastic surfaces for two hours to nine days. According to the World Health Organization, the virus is unable to survive for long periods of time on packages or letters.

So, the answer here is that no one knows the exact time at this point, but “not long” is the best answer.

If there is concern that a surface is infected, clean the surface first with soap and water if dirty. Then, use household disinfectant sprays or wipes to kill the virus and protect yourself and others.

If someone comes down with the coronavirus and is strong enough to survive, how long is the duration of the illness and when is it safe to go out in public again?

If someone is diagnosed with COVID-19, the duration of the illness can vary. The CDC says patients can be discharged from healthcare facilities “whenever clinically indicated.”

What is the latest information on the mortality rate of COVID-19 and is it higher in the U.S. than other countries?

The data on mortality for SARS-COV-2 is still a moving target and varies by age group and underlying health conditions (those with lung disease, heart disease or other conditions that impair the immune system are more susceptible).

As of March 5 in the U.S., there have been 177 confirmed cases with 11 deaths (6.21%) versus 97,841 total confirmed cases in the world and 3,347 deaths (3.4%).

It should not be interpreted that the U.S. has double the mortality compared to the rest of the world. It likely means we have not identified people who are infected but with mild symptoms, who may not feel sick enough to see a doctor. In an epidemic, usually the sickest people are identified first. As we begin to test more patients in the community, we will likely see a steady decrease in the mortality rate comparable to other parts of the world.

Is the coronavirus able to spread via recirculated air, like in office buildings, hospitals, public transit vehicles and our homes?

According to researchers at Purdue University, COVID-19 could circulate inside cruise ship air conditioning systems. They say on aircraft, the coronavirus is more likely to spread by touch than through the air. And the World Health Organization says there is “very little risk” of any communicable disease being transmitted on board an aircraft.

Do I need a face mask?

Many people are wondering if they need a face mask — and are worried about price gouging.

Yes, some of these masks are going for hundreds of dollars on Amazon, and local stores are in short supply. But luckily, you really don't need a mask unless you are the one with the virus, or if you're working in the medical field.

Masks stop germs from spreading. They're not necessarily helpful in protecting yourself from the virus.

The general public is being told not to wear face masks as they won’t help keep us from getting sick, but health professionals are supposed to wear them. Why do the masks protect them but not us?

Health professionals need to wear face masks because they are in very close contact with sick patients throughout the day as part of their job. It is also recommended that those who are taking care of someone who may have COVID-19 wear a face mask when in close contact.

It is not recommended that people who are well wear a face mask as it is not the most effective way to protect yourself.

The most effective way to protect yourself and others includes frequent hand washing with alcohol-based hand rub or soap and water, covering your cough with the bend of your elbow or tissue and maintaining distance from those who are coughing or sneezing.

Are infected people recovering?

People also want to know what happens to people after they're infected with the virus. There's some good news here, according to Dr. Sean Whelan from Washington University's Department of Molecular Biology.

"People are OK after they get the virus, 98% who get tested recover and then presumably are immune for the rest of their life," Whelan said.

Is it safe to travel?

We've also received several questions about travel. You might need to change your plans, depending on where you're headed.

The Centers for Disease Control said to only travel to China and South Korea if necessary. If you're older or have a serious medical condition, avoid Japan, Iran and Italy. If you're staying in the U.S., you should be good to go.

Many airports said they're keeping a close eye on the virus, like LAX, which is sanitizing the airport every hour.

I am supposed to go to Seattle this week, is it foolish to go?

The CDC provides notices based on the risk in travelling to specific areas. It is recommended to avoid nonessential travel to destinations with warning level 3 travel notices (China, Iran, South Korea, and Italy) because of the risk of acquiring COVID-19.

People in high-risk groups, including older adults and those with chronic medical conditions, traveling to alert level 2 destinations (Japan) should talk to a healthcare provider and consider postponing their trip because COVID-19 can be more serious in these groups.

CDC does not recommend canceling/postponing travel to destinations with watch level 1 travel notices because the risk is low. A list of destinations with travel notices is available on the CDC website here.

You can consider cancelling trips if the anxiety of going would make you not enjoy your trip. If you travel, take the following precautions:

  • Avoid contact with sick people
  • Avoid touching your eyes, nose or mouth with unwashed hands
  • Clean your hands often by washing them with soap and water for at least 20 seconds or using alcohol-based sanitizer that contains 60% alcohol


Could my online orders carry coronavirus?

People are worried about online orders from China, from sites like Amazon or Wish. But according to the Centers for Disease Control, there's little chance the virus would spread like this.

There's no evidence that coronavirus in the US is associated with imported goods. So right now, don't worry about your online shopping habits.

Are there coronavirus tests available in St. Louis? If yes, will your regular physician have access to them in their office or does a patient have to go somewhere else for testing?

The CDC has shipped the laboratory test kit for the COVID-19 (SARS-CoV-2) to approved laboratories, which includes Missouri's state public health department laboratory.Currently, this test is not available at local clinics but can be sent by a healthcare provider to the health department during a routine visit.

A healthcare provider will determine if a patient has signs, symptoms and the appropriate exposures compatible with COVID-19 and will then provide materials for testing. The decision on which patients receive testing should be based on the local epidemiology of COVID-19 as well as clinical course of illness.

Commercial labs are working to develop their own tests that will hopefully be available soon.


And according to Google Trends data, these are the top 10 things people are searching about the coronavirus:

1. What is the coronavirus? 


2. How do I prepare for the coronavirus?


  • Avoiding close contact with those who are sick
  • Stay home if you are sick
  • Cover your coughs and sneezes with a tissue.





3. How many people have died from the coronavirus?

Globally, COVID-19 has affected more than 83,000 people and killed more than 3,000. You can see updated numbers from the CDC here.


As of March 3,  there are more than 100 cases of persons infected with the virus in the U.S. Of those infected, 48 of then involve people repatriated to the U.S. from Wuhan, China or from the Diamond Princess Cruise Ship that was quarantined in Japan.

There are 60 total cases of infection detected in the U.S. through public health surveillance systems. Twenty-two of these 60 cases are travel-related, and 11 are believed to be through person-to-person spread. The sources of 27 infections are still under investigation.

Cases have been reported in at least 12 states.


This was also the seventh most searched question about the coronavirus.

5. How did the coronavirus get started?




6. How is the coronavirus spread? 



8. What are the symptoms of the coronavirus?


9. Where did the coronavirus originate? 



10. Is the coronavirus worse than the flu?


Here's what we can compare: 

The seasonal flu, which includes influenza A and influenza B viruses, and COVID-19 are both contagious viruses that cause respiratory distress. The viruses share some symptoms: fever, cough and shortness of breath. Flu symptoms also includes muscle or body aches, headaches, fatigue, and vomiting and diarrhea.
