Should You Be Tested for COVID-19?

More tests for COVID-19 are now available, but not everyone needs to be tested, especially if they don’t have symptoms.

As SARS-CoV-2 infections continue to spread, many people are probably wondering if they should be tested for COVID-19.

“To learn if you have a current infection, viral tests are used. Most people have mild illness and can recover at home without medical care. Contact your healthcare provider if your symptoms are getting worse or if you have questions about your health.​​”

CDC on Testing for COVID-19

While it might sound like a good idea, especially if there are many COVID-19 cases in your area, getting tested for SARS-CoV-2 isn’t as easy as you might think it should be…

Should You Be Tested for COVID-19?

What’s the biggest problem with getting tested for SARS-CoV-2?

Since this is a new infection, a new test had to be developed to detect it.

And believe it or not, that test is still not widely available.

“The California Department of Public Health announced today that new CDC test kits used to detect Coronavirus Disease 2019 (COVID-19) now available in California can be used to do diagnostic testing in the community. California will immediately receive an additional shipment of kits to test up to 1,200 people.”

COVID-19 Testing Kits Arrive at State Public Health Laboratories

While more and more communities now have COVID-19 test kits, getting tested often still means a long wait for the test and an even longer wait for the results.

The CDC is now shipping its laboratory test kit for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to qualified state and local public health laboratories.

But what happens if you think that you have COVID-19?

Can you get tested?

While there were originally strict criteria for who could get a test, including folks with COVID-19 symptoms, those who had contact with a known case, and anyone with recent travel to a hot spot, it has gotten to where almost anyone can get a test.

Not everyone needs a test though…

“Can someone test negative and later test positive on a viral test for COVID-19?

Yes, it is possible. You may test negative if the sample was collected early in your infection and test positive later during this illness. You could also be exposed to COVID-19 after the test and get infected then. Even if you test negative, you still should take steps to protect yourself and others.”

COVID-19 Frequently Asked Questions

Should you get tested if you were exposed to someone with COVID-19?

While it might seem like a good idea, understand that if you test negative, it doesn’t mean that you won’t develop symptoms and test positive later on in your incubation period (up to 14 days).

Are you going to get tested every day?

So no, you probably don’t need to be tested simply because you were exposed. You should self-quarantine yourself though and can consider testing if you later develop symptoms.

And you likely don’t need to get tested if you weren’t a close contact (within 6 feet of an infected person for at least 15 minutes) of someone with COVID-19. Besides the fact that testing is still limited and should likely be reserved for those with symptoms, a negative test one day simply means that you are negative that day. Again, you could develop symptoms the next day or even later that day…

What Tests Are Used to Diagnose Covid-19?

If you are going to get tested for COVID-19, do make sure you get the right test though.

“A viral test tells you if you have a current infection.”

CDC on Testing for COVID-19

You want to get a viral test (preferably the PCR test, as it is more reliable than the antigen test), and not the antibody test (blood test), which detects past infections.

Remember though, since there is no specific treatment for COVID-19, the only thing a positive test does is reinforce your need for self-isolation.

“For COVID-19, the period of quarantine is 14 days from the last date of exposure, because 14 days is the longest incubation period seen for similar coronaviruses.”

COVID-19 Frequently Asked Questions and Answers

Testing can help identify folks who really need to be quarantined, keeping them from getting others sick, and it can help with contact tracing.

While that can be useful, it is also important to understand that the COVID-19 tests can have false-negative results. So if you think you have symptoms of COVID-19, stay in quarantine even if you have a negative test.

What to Know About COVID-19 Testing

More tests for COVID-19 are now available, but not everyone needs to be tested, especially if they don’t have symptoms.

Can Your Sick Child Still Go to Daycare or School?

Is your child to sick to go to school or daycare?

There are a lot of different rules that dictate when kids can go to daycare or school when they are sick.

Kids don't always have to stay at home from daycare or school when they are sick.
Kids don’t always have to stay home from daycare or school when they are sick.

The actual rules of your daycare or school are the ones that you are likely most familiar with, but there are also recommendations from the American Academy of Pediatrics and the CDC, in addition to  state-specific regulations.

Can Your Sick Child Still Go to Daycare or School?

Most people know to stay home when they are sick.

“Stay home when you are sick. If possible, stay home from work, school, and errands when you are sick. You will help prevent others from catching your illness. Avoid close contact with people who are sick.”

CDC on Information for Schools & Childcare Providers

But what exactly does it mean to be “sick” and how long are you supposed to stay home and avoid other people?

“Most minor illnesses do not constitute a reason for excluding a child from child care, unless the illness prevents the child from participating in normal activities, as determined by the child care staff, or the illness requires a need for care that is greater than staff can provide.”

Recommendations for Inclusion or Exclusion (Red Book)

In general, your child does not need to be kept home and out of daycare or school if they are able to participate in routine activities, do not need extra care, and have:

  • a cold (unless they have a fever) or other upper respiratory infection, even if they have a green or yellow runny nose
  • RSV (unless they have a fever)
  • croup (unless they have a fever)
  • diarrhea that can be contained in a diaper or the child can make it to the bathroom without having an accident, as long as they aren’t having more than 2 stools above their usual or stools that contain blood or mucus
  • a rash without fever – most skin rashes won’t keep your kids out of school, like if they have poison ivy, hives, or even molluscum contagiosum and warts
  • Fifth disease – interestingly, you aren’t contagious once you have the characteristic Fifth disease rash
  • head lice – why not keep kids out of school if they have lice? It doesn’t stop them from spreading. They can get them treated at the end of the day.
  • pinworms – like lice, keeping kids out of school with pinworms isn’t going to stop them from spreading, although kids should be treated
  • pink eye – if caused by an infection, in general, should be able to stay or return if is improving, but keep in mind that most experts now think that kids with pink eye do not need to be excluded from daycare or school at all
  • oral lesions and are able to contain their drool (unless they have a fever), which would include hand foot mouth disease
  • skin lesions that can be covered, and if they can’t, then they can return after they have been on antibiotics for 24 hours (impetigo) or have started treatment (ringworm)
  • strep throat and have been fever free and on antibiotics for 24 hours
  • scabies – if you have started treatment
  • a sore throat (unless they have a fever)

Why don’t you have to keep your kids home when they have RSV or many of these other common childhood diseases?

In addition to the fact that some kids would never get to go to daycare or school, since these diseases are so common, many kids continue to be contagious even after their symptoms have gone away. So excluding them doesn’t really keep the illnesses from spreading through the daycare or school.

So why not just send them when they have a fever or really don’t feel well?

In addition to the possibility that they might be a little more contagious at those times, it is because the typical daycare or school isn’t able to provide the one-on-one care that your child would likely need when feeling that sick, as your child probably isn’t going to want to participate in typical group activities.

Policies that are overly strict at excluding children from daycare and school may also lead to antibiotic overuse, as parents rush their kids to the doctor for and push for a quick cure because they need to go back to work.

Exclusion Criteria for Vaccine Preventable Diseases

While the exclusion criteria for many diseases simply extends to when your child is fever free, starts treatment, or feels well enough to return to daycare or school, for many now vaccine-preventable diseases, you will be excluded (quarantined) for much longer:

  • hepatitis A virus infection – exclusion for one week after illness starts
  • measles – exclusion until four days after start of rash
  • mumps – exclusion until five days after start of parotid gland swelling
  • pertussis – exclusion until completes five days of antibiotics or has had cough for at least 21 days
  • rubella – exclusion until seven days after start of rash
  • chicken pox – exclusion until all lesions have crusted
  • diphtheria – if survives having respiratory diphtheria, would likely be excluded until finishes treatment and has two negative cultures at least 24 hours apart
  • rotavirus – as with other diseases that causes diarrhea, children should be excluded until “stool frequency becomes no more than 2 stools above that child’s normal frequency” as diarrhea is contained in the child’s diaper or they aren’t having accidents
  • tetanus – if survives having tetanus, wouldn’t be excluded, as tetanus is not contagious

Unfortunately, kids are often contagious with many of these diseases, especially measles and chicken pox, even before they have obvious symptoms, which is why large outbreaks used to be so common.

Children will often be excluded from daycare or school if they are unvaccinated or not completely vaccinated and they are exposed to a vaccine-preventable disease.
