33 hours ago · Reporting can be provider based, laboratory based, or both. Clinicians who are unsure of state and local reporting requirements should seek advice from state or local health department STI programs. STI and HIV reports are kept confidential. In most jurisdictions, such reports are protected by statute or regulation. Before conducting a follow ... >> Go To The Portal
The testing site that performs the COVID-19 test is responsible for reporting to the appropriate state or local public health department.
COVID-19 case investigations are typically initiated when a health department receives a positive SARS-CoV-2 test result report from a laboratory or a patient’s confirmed or probable diagnosis of COVID-19 from a healthcare provider.
There's a chance that your COVID-19 diagnostic test could return a false-negative result. This means that the test didn't detect the virus, even though you actually are infected with it.
“The high percentage of positive antigen test results during the 5–9 days after symptom onset reinforces the importance of correct and consistent mask use during this period,” the CDC said.
Health departments are responsible for conducting COVID-19 case investigations and contact tracing and often have legal mandates to investigate cases of communicable disease and a duty to notify contacts that they were exposed. Health departments should initiate investigations as quickly as possible.
Scientists and public health workers are also working to stop the spread of COVID-19 through contact tracing. In this strategy, public health workers talk to people with COVID-19 to learn about all the people they were physically close to while they were potentially able to spread the disease.
If you use an at-home test that comes back negative, and you do have symptoms that persist or get worse, it's a good idea to get a lab-based PCR test for COVID-19 and influenza. You also should stay home and isolate until you get the PCR test results back. The antigen test may have missed an early infection.
See full answerA negative test result means that the virus that causes COVID-19 was not found in your sample. However, it is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID- 19. You might test negative if the sample was collected early during your infection.You could also be exposed to COVID-19 after your sample was collected and then have become infected. In particular, people infected with COVID-19 but who have no symptoms may not shed enough virus to trigger a positive test. This means that you could possibly still have COVID-19 even though the test result is negative.
Reverse transcription polymerase chain reaction (RT-PCR)-based diagnostic tests (which detect viral nucleic acids) are considered the gold standard for detecting current SARS-CoV-2 infection.
Most people with COVID-19 are no longer contagious 5 days after they first have symptoms and have been fever-free for at least three days.
It is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID- 19. This means that you could possibly still have COVID- 19 even though the test is negative. The amount of antigen in a sample may decrease the longer you have symptoms of infection.
False positives—when someone receives a positive test result even though they are not infected—are rare occurrences. They are most likely to occur when an at-home test is not administered according to the manufacturer's instructions.
