Description

For sample adults and sample children with mild, moderate, or severe symptoms when at their worst or refused or didn't know the severity of their symptoms (CVDSYMP), CVDSYMPNOW indicates if they are currently experiencing Long COVID symptoms.

This variable is one of two Long COVID-related questions added by NCHS in 2022. See CVDLONG for the other post-COVID variable added in 2022.

NCHS defines post-COVID conditions, or Long COVID, as a wide range of new, returning, or ongoing health problems people can experience four or more weeks after first being infected by the virus that causes COVID-19.

Long term symptoms include tiredness or fatigue, difficulty thinking, difficulty concentrating, forgetfulness or memory problems sometimes referred to as "brain fog," difficulty breathing or shortness of breath, joint or muscle pain, fast-beating or pounding heart (also known as heart palpitations), chest pain, dizziness on standing, depression, anxiety, or mood changes.

NCHS added nearly 30 questions related to COVID starting in quarter 3 of the 2020 NHIS questionnaire, eight of which are asked of both sample adults and sample children. For the full list of variables, as well as information about COVID-related changes to the NHIS, please see the user note.
