Hello, i had contact with the patient with covid-19 for more than 30 minutes the day before yesterday, and the test was negative yesterday. do i need to have another test after12 days? some people say that the new crown has an incubation period

COVID-19 Incubation: On average, the time from exposure to symptom onset (known as the incubation period) is about five to six days. However, studies have shown that symptoms could appear as soon as three days after exposure to as long as 13 days later. These findings continue to support the CDC recommendation of self-quarantine and monitoring of symptoms for 14 days post exposure.
