Long COVID, also known as post-COVID conditions, is a term used to describe the chronic health issues that some individuals experience after being infected with SARS-CoV-2, the virus that causes COVID-19. Medical professionals define Long COVID as a condition that persists for at least three months following the initial infection. It’s characterized by a diverse array of symptoms and health problems that can fluctuate in severity, come and go, or remain constant over time.
Long COVID Can Affect Anyone
While Long COVID is more frequently observed in individuals who experienced severe COVID-19 illness, it’s important to understand that anyone infected with SARS-CoV-2 can develop this condition, including children. It’s a misconception that only those severely ill are at risk; even individuals with mild initial infections can experience long-term symptoms.
Many people with Long COVID notice symptoms emerging in the days and weeks following their initial COVID-19 diagnosis. However, in some instances, individuals who later develop Long COVID may not even recall when they were initially infected. Adding to the complexity is the fact that individuals can be reinfected with SARS-CoV-2 multiple times, and each subsequent infection carries a risk of developing Long COVID. The symptoms of Long COVID are incredibly varied and can include a wide range of conditions that may appear, disappear, and reappear over weeks and months. These symptoms can range from mild annoyances to severe, debilitating conditions requiring extensive medical care, and in some cases, can even lead to long-term disability.
Although the rate of new Long COVID cases has decreased since the peak of the pandemic, it remains a significant public health concern. Millions of adults and children in the United States continue to be affected by the long-term consequences of COVID-19.
Who is Most Vulnerable to Long COVID?
While anyone who contracts COVID-19 can potentially develop Long COVID, research has identified certain groups who are at a higher risk. It’s important to note that this is not an exhaustive list, but these populations have been shown to be more susceptible:
- Women: Studies indicate women are more likely to develop Long COVID compared to men.
- Hispanic and Latino Individuals: This demographic group has been disproportionately affected by Long COVID.
- Individuals with Severe Initial COVID-19 Illness: Those who required hospitalization or intensive care during their initial COVID-19 infection are at a significantly higher risk.
- People with Pre-existing Health Conditions: Individuals with underlying health issues and older adults aged 65 and above are more vulnerable.
- Unvaccinated Individuals: Vaccination against COVID-19 significantly reduces the risk of developing Long COVID.
The Role of Health Disparities in Long COVID Risk
It’s crucial to acknowledge that health disparities stemming from factors such as disability, economic status, geographic location, and other social determinants disproportionately impact certain communities. These inequities can exacerbate the risk of negative health outcomes and the impact of Long COVID within these vulnerable populations.
Preventing Long COVID
The Centers for Disease Control and Prevention (CDC) emphasizes the importance of core prevention strategies to minimize health risks associated with COVID-19, including severe illness, hospitalization, and death. Preventing severe COVID-19 outcomes is a key factor in Long COVID prevention. Effective measures to protect yourself and others include:
Vaccination as a Primary Prevention Tool
Research clearly demonstrates that COVID-19 vaccination is the most effective tool currently available to prevent Long COVID, and this benefit extends to children as well as adults. Vaccination significantly reduces the likelihood of developing long-term symptoms following a COVID-19 infection.
Diagnosing Long COVID
It’s important to understand that Long COVID isn’t a single, uniform illness. Currently, there isn’t a specific laboratory test that can definitively diagnose Long COVID. A previous positive SARS-CoV-2 test is not a prerequisite for a Long COVID diagnosis. Healthcare providers diagnose Long COVID based on a comprehensive evaluation that includes:
- Medical History Review: A thorough review of your health history.
- COVID-19 Diagnosis History: Information on whether you had a confirmed COVID-19 diagnosis through testing, symptoms, or known exposure.
- Physical Examination: A complete health examination.
It’s noteworthy that standard clinical evaluations and routine tests like blood work, chest X-rays, and electrocardiograms may often appear normal in individuals with Long COVID. If you suspect you or your child may have Long COVID, it’s essential to consult a healthcare provider. They can develop a personalized medical management plan to help alleviate your symptoms and improve your overall quality of life.

Conditions Similar to Long COVID
Some individuals with Long COVID symptoms experience symptoms that are similar to those reported by people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and other chronic illnesses that can emerge following infections. These unexplained symptoms can sometimes be misunderstood or dismissed by healthcare providers, potentially leading to delays in diagnosis and appropriate care or treatment.

CDC’s Efforts to Address Long COVID
The CDC is actively collaborating with other federal agencies to enhance our understanding of the long-term effects of Long COVID, identify who is most affected, and determine the underlying reasons for its development. The CDC supports these objectives through various initiatives:
- Partnerships with State and Local Health Departments: Collaborating with health agencies at different levels to address Long COVID at the community level.
- Support for Healthcare Providers: Providing resources and guidance to healthcare professionals to better diagnose and manage Long COVID.
- Promoting and Conducting Research: Actively engaging in and supporting research efforts to further our knowledge of Long COVID.
Ongoing Research on Long COVID
Numerous research studies are underway to deepen our understanding of Long COVID and identify additional strategies for prevention and treatment. The CDC and its research partners are employing diverse approaches to estimate:
- Prevalence and Causes: Determining how many people experience Long COVID and the factors that contribute to its development.
- Disproportionately Affected Groups: Identifying which populations are more heavily impacted by Long COVID.
- Impact of New Variants: Investigating how new SARS-CoV-2 variants may influence the occurrence and characteristics of Long COVID.
- Vaccination’s Protective Role: Further examining the role of COVID-19 vaccination in preventing Long COVID.
Each research approach contributes valuable insights into Long COVID, helping healthcare providers to better treat and support patients living with these long-term effects. The CDC regularly publishes data and analyses on Long COVID, with the most recent information available through the U.S. Census Bureau’s Household Pulse Survey. The CDC remains committed to sharing updated information with healthcare providers to aid in the evaluation and management of Long COVID.
