Cough first time today last week tuesday and wednesday my nose was blocked from sunday again block and sneezing and my 12months old baby also sneezing there is a need to get tested for covid?

Testing not necessar: If you have Covid, you need to self-isolate. Quarantine yourself. Drink lots of fluids, esp electrolyte solutions, rest, Take Acetaminophen for fever/pain and eat a bland diet (Bananas/Rice/Apples/Toast). See a Dr for worsening difficulty breathing, blue lips/face, confusion/lethargy, and persistent chest pain. Testing may be necessary to return to work, but otherwise does not change treatment.
