How to read eye charts and check if your eyes are infected

The U.S. Centers for Disease Control and Prevention has released new guidelines for people to follow when seeing a doctor or seeing a specialist if they have been diagnosed with coronavirus.ABC News/Washington Post reporter Julie McCarthy and the Associated Press obtained the guidance from the CDC’s National Center for Emerging and Zoonotic Infectious Diseases and the U.K.’s National Health Service (NHS).

The guidelines say the best way to determine if you or someone you know is at high risk of catching coronaviruses is to get a detailed medical history, take a blood test, or take a special test called an ECG.

They say the test can provide a good indication of whether you or your loved one has been infected with the coronaviral strain.ABC/Washington post reporter Julie Pelosi contributed to this report.ABC’s John Santucci contributed to the report.
