2. IfIsuspectIhaveCOVID-19,whatshouldIdo?
Ifyou(asapatient)oralovedone(acaregiver)exhibitsthesymptomsofCOVID-19(includingbutnotlimitedtofever,drycough,shortnessofbreath),immediatelyfollowself-quarantineprocedures.Immediatelycontactyourhealthcareprovider(couldbeyourprimarycarephysician)aboutwhetheryouneedtogettested.Yourhealthcareproviderwillbeabletoguideyouonnextsteps.TheCDCandtheAssociationofPublicHealthLaboratoriesmaintainalistoflaboratoriesthatarecurrentlyconductingCOVID-19tests.PleaserememberthatyoumaynothavesymptomsevenifyouareinfectedwithSARS-CoV-2.Socialdistancingistheonlywaytoavoidgettinginfectedwiththevirus.Asacaregiver,pleasetakeextraprecautionswhenyouneedtoleaveyourhouseorapartment.3.
