Yes, you can test too early for COVID-19, which can lead to a false negative result because there might not be enough viral load for the test to detect; if you have symptoms, test immediately and again later, but if you're asymptomatic after exposure, wait at least 5 days to test to get an accurate result. 

What are the first symptoms to appear after incubation?

During the incubation period, germs take up residence in your body and start making copies of themselves (reproducing). Soon, your immune system takes notice and jumps into action to clear out the invaders. This immune response leads to inflammation and symptoms like a sore throat, runny nose, rash or diarrhea.

The symptoms of the Delta variant may be more severe than the ones of the Omicron variant, resulting in a higher risk of severe illness, hospitalization, and even death. This risk is significantly higher for unvaccinated people or people in a risk group.

How long can COVID live on bedding?

COVID-19 can survive on porous materials like bedding for a shorter time than hard surfaces, with studies showing it can last about two days on some fabrics, though droplets evaporate faster on fabric as they dry out quickly. The virus thrives better on smooth surfaces like plastic or metal, but regular washing with soap and water effectively removes it from bedding and prevents transmission. 

What are the two most common signs of COVID?

Symptoms of COVID-19

• a high temperature – you may feel hot, cold or shivery, or your skin is hot to touch on your chest or back (you do not need to measure your temperature)
