COVID-19 and Infectious Disease Claims at Work

Getting workers' compensation for COVID-19 or another infectious disease is usually harder than for a broken bone, because the law starts from the assumption that a contagious illness is something anyone could catch anywhere — not something your job caused. To succeed, you generally have to show that your work exposed you to a materially greater risk of catching the disease than the general public faced, and that you actually caught it through that workplace exposure. Some states have made this easier for certain frontline workers through a legal "presumption," but those rules vary a great deal from state to state and many of the emergency-era COVID-19 presumptions have expired. Here's how the law generally treats infectious-disease claims, what evidence tends to matter, and what to do if you were exposed or got sick at work.

No-fault still applies — but you still have to prove work-relatedness

Workers' compensation is a no-fault system. You generally do not have to prove your employer did anything wrong, and your own ordinary carelessness generally does not bar your claim. In exchange, comp is usually your exclusive remedy against your employer — you typically cannot sue the employer in court, though you may still have a claim against a negligent third party (someone other than your employer or a coworker). If you do recover from a third party, the comp insurer usually has a lien or subrogation right to be repaid out of that recovery.

No-fault does not mean automatic. For any claim, you still have to show the injury or illness arose out of your employment (the work caused it or increased the risk) and occurred in the course of your employment (in the time, place, and circumstances of the job). With a contagious disease, that first element — arising out of the work — is exactly where the fight happens, because the whole world is a possible source of infection.

The core problem: an "ordinary disease of life" often isn't covered

State comp systems generally split illness claims into two buckets. Occupational diseases — illnesses caused or made materially more likely by conditions peculiar to your job — are typically covered. "Ordinary diseases of life" — illnesses the general public is exposed to regardless of occupation, like the common cold or seasonal flu — are typically not covered on their own, because nothing about the workplace made you more likely to catch them than anyone else out in the world.

That second category is the wall most infectious-disease claims run into. Unless a presumption applies (more below), the usual approach in state occupational-disease law is to require proof that the job put you at a distinctly greater risk than the public faced, and that the illness was not just ordinary community spread. This distinction is written into state statutes. Virginia, for example, defines an occupational disease as one arising out of and in the course of employment "but not an ordinary disease of life to which the general public is exposed outside of the employment," and then allows an ordinary disease of life to be treated as compensable only if the worker proves — by a heightened, clear-and-convincing standard — that it arose out of the employment, did not result from causes outside the employment, and is characteristic of and caused by conditions peculiar to the work (Va. Code §§ 65.2-400, 65.2-401). Other states word it differently, and how each one applies that idea to COVID-19 specifically is still being worked out in some places. The exact test is state law — check yours.

How you can still build a claim without a presumption

Even with no special presumption, a compensable claim generally turns on two questions:

1. Did my job put me at meaningfully higher risk than the public? Close, sustained contact with sick people — a hospital, nursing home, jail, or a workplace with a documented outbreak — is very different from a job with no known exposure.
2. Did I actually catch it there, and not somewhere else? This causation question is usually the harder one, and the insurer will look closely at your timeline and at any household or community exposures.

A virus doesn't come with a receipt showing where you picked it up, so these claims often live or die on circumstantial evidence gathered carefully and early. Expect the insurer to scrutinize the claim: it may send you to an independent medical examination (IME) with a doctor it selects, and it may run proposed treatment through utilization review to decide whether it is medically necessary. Neither is a sign you did anything wrong; both are normal parts of the process.

State presumptions: what they are, and why you can't assume one applies to you

During the COVID-19 emergency, a number of states enacted laws, emergency rules, or executive orders creating a rebuttable presumption for certain workers: if you were diagnosed with COVID-19 while working a covered job during a covered period, the illness was presumed work-related, and it became the employer's or insurer's burden to prove otherwise — flipping the usual burden of proof.

These presumptions were never nationally uniform. Who was covered ranged from first responders and health care workers, to broader categories of "essential" or frontline workers, and in some states to a wider set of workplaces — and coverage was usually tied to a specific emergency-declaration window rather than an open-ended rule.

Many of these presumptions have expired or sunset as states wound down their emergency declarations. California's COVID-19 presumptions, among the broadest in the country, expired at the start of 2024; California workers can still pursue COVID-19 claims, but under the ordinary rules for proving a disease is work-related rather than with a presumption. Some states have kept or reinstated narrower presumptions for specific occupations, and some had, well before COVID-19, built infectious-disease or communicable-disease presumptions into their firefighter, EMS, corrections, or first-responder statutes — which may still reach diseases caught on the job.

None of this is safe to assume from memory, from an old article, or from another state's rule. Check whether your state currently has a COVID-19 or infectious-disease presumption in effect, and exactly who it covers, directly with your state workers' compensation agency or board. You can find your state's agency through the U.S. Department of Labor's directory of state workers' compensation officials. A presumption that existed a few years ago may not be law today — and even where a presumption applies, it is rebuttable, not a guaranteed outcome.

What evidence matters most

• Documented workplace exposure — an exposure incident report, contact-tracing records, coworkers who tested positive around the same time, or your employer's own outbreak log.
• Timing — when you were exposed at work, when symptoms started, and when you tested positive, lined up against the disease's typical incubation period.
• Your actual duties and setting — close, sustained, or unprotected contact with infected or likely-infected people, not just "I go to a workplace."
• Employer and public-health records — outbreak reports, OSHA injury-and-illness recordkeeping entries, or a health department outbreak investigation.
• A treating doctor's causation opinion — often the single most important piece of evidence in a contested claim.
• Your own contemporaneous notes on dates, symptoms, and exposures, written down as they happen rather than reconstructed months later.

Everything you submit should be accurate. Describe honestly what happened, what your symptoms are, and what other exposures you may have had. Exaggerating symptoms, hiding a prior condition, or misdescribing how you were exposed is fraud, it is prosecuted, and it can sink an otherwise legitimate claim. A well-documented, truthful claim is the strongest kind.

What to do if you were exposed or got sick at work

1. Get medical care and get tested as soon as symptoms appear, and tell the provider you believe the exposure happened at work. (Who may treat you, and whether you or the employer picks the doctor, varies by state.)
2. Report the exposure or illness to your employer in writing right away. Notice deadlines are set by state law and are often short — report first, rather than waiting to see whether you get better.
3. Ask your employer whether there was a known outbreak around the time you were exposed, and request any records they will share.
4. Keep your own log of dates, symptoms, coworkers who were also sick, and conversations about exposure.
5. File your workers' comp claim promptly. The filing deadline is separate from the notice deadline, is also state-specific, and is not something to estimate — confirm it with your state agency now.
6. Ask your doctor to document work-relatedness in the medical record, not just the diagnosis.
7. If the claim is denied, states provide an appeal or hearing process with its own deadline — ask your state agency about it as soon as you receive the denial, because appeal windows can be very short.
8. Get help. Most state agencies have an ombudsman or information officer who can answer procedural questions for free. For a serious or contested case, consider consulting a workers' compensation attorney; attorney fees in comp cases are regulated and typically must be approved by the state agency or board, so ask how fees work in your state before you sign anything.

Medical benefits versus wage benefits

If an infectious-disease claim is accepted, it generally opens two different kinds of benefits. Medical benefits pay for reasonable and necessary treatment for the work-related condition. Wage-replacement benefits pay a portion of lost earnings while you cannot work, or cannot earn what you used to — these are calculated from your average weekly wage, and the formula, the rate, any waiting period, and any cap are all set by state law. Time-limited benefits while you are recovering are usually called temporary total disability (TTD) if you cannot work at all, or temporary partial disability (TPD) if you can work reduced hours or lighter duty for less pay.

When your condition stabilizes and is not expected to improve further, doctors call that maximum medical improvement (MMI). MMI is the pivot point: temporary benefits typically end, and the question becomes whether you have permanent impairment, which is compensated as permanent partial disability (PPD) or, if you cannot return to any sustained work, permanent total disability (PTD). How impairment is rated and paid varies enormously between states.

Long COVID as an ongoing disability

Some workers recover fully; others develop lingering symptoms — fatigue, cognitive difficulty, shortness of breath, post-exertional malaise — that persist for months or longer and interfere with the ability to work. If a workers' comp claim for the underlying COVID-19 infection is accepted, ongoing long COVID symptoms may continue to support medical and wage benefits under that same claim, provided your treating doctor documents the connection and you have not yet reached maximum medical improvement.

Separately, if long COVID leaves you unable to sustain full-time work — regardless of where you caught it — it can be evaluated as a disabling condition under the Social Security disability programs (SSDI/SSI), which look at your overall functional limitations rather than at where the illness came from. For how the Social Security Administration evaluates these claims, see our guide: Getting Disability for Long COVID. Workers' comp and SSDI can interact — some workers' comp payments can reduce (offset) SSDI benefits — so if you are pursuing both, keep each program informed about the other.

Other infectious diseases: needlesticks, hepatitis, and TB

COVID-19 is far from the only infectious-disease scenario workers' comp deals with, especially in health care, corrections, laboratory, and first-responder settings.

• Bloodborne pathogens and needlesticks. Workers with occupational exposure to blood or other potentially infectious materials are covered by OSHA's bloodborne pathogens standard (29 CFR 1910.1030), which requires the employer to maintain a written exposure control plan, use safer devices and engineering controls, offer hepatitis B vaccination, and provide prompt post-exposure evaluation and follow-up after a needlestick or splash. A documented needlestick, followed by post-exposure care and any resulting infection, is often easier to prove than a COVID-19 claim, because the exposure event is specific and sudden — closer to a traumatic injury than to diffuse community spread. Report it immediately and make sure the exposure and the follow-up are both in writing.
• Tuberculosis and other airborne diseases. Workers with regular contact with higher-risk populations (health care, corrections, homeless services) may have a stronger case for elevated occupational risk, particularly where there is a documented exposure incident or a known case at the facility. Baseline and follow-up testing records help enormously here.
• Diseases with their own state-specific rules. Some states have presumption statutes covering diseases such as hepatitis, meningitis, or other communicable diseases for specific job categories — often first responders and corrections officers — structured much like the COVID-19 presumptions described above. Whether one applies depends entirely on your state and your job classification, so confirm it with your state agency.

The same framework runs through all of these: document the exposure event, get prompt medical care and testing, report it in writing, and get your doctor's opinion connecting the diagnosis to the workplace.

If you're a federal, maritime, or railroad worker, you're in a different system

State workers' comp is not the only game. Federal civilian employees are covered by the Federal Employees' Compensation Act (FECA), administered by the Department of Labor's Office of Workers' Compensation Programs, with its own claim forms and deadlines. Many maritime and harbor workers fall under the Longshore and Harbor Workers' Compensation Act, also administered by OWCP. Seamen bring claims under the Jones Act and railroad workers under the Federal Employers' Liability Act (FELA) — and those two are importantly different: they are fault-based lawsuits in which the worker must prove employer negligence, not no-fault comp claims. If you fall into one of these groups, the rules in this article about state agencies and state presumptions do not describe your system; get information specific to it.

A note on what's still unsettled

This area of law moved quickly and unevenly. Many COVID-specific presumptions were tied to emergency declarations that have since ended, and legislatures have debated — without uniformly adopting — permanent replacements. How "ordinary disease of life" doctrine applies to COVID-19 is still developing in some states. Treat anything you read about a particular state's presumption, including here, as a starting point rather than a final answer, and confirm the current rule with your state agency before relying on it.

Deadlines: short, state-specific, and easy to miss

Every stage of an infectious-disease comp claim runs on a clock: the deadline to report the exposure or illness to your employer, the deadline to file the claim, and the deadline to appeal a denial. All three are set by state law, they differ from state to state, they are often shorter than people expect, and they are not something to guess at. If you take one thing from the procedural side of this article, make it this: look up your state workers' compensation agency's current deadlines the same week you are exposed or diagnosed — not after you have recovered, and not after a claim has been denied.

Filing a workers' comp claim is not "suing" your employer. It is using a no-fault insurance system that exists precisely for work-related injury and illness, and that your employer is required to carry in most circumstances. An honest, promptly reported, well-documented claim is exactly what the system is designed to handle.

This article provides general information only and is not legal advice, and it does not create an attorney-client relationship. Workers' compensation rules, infectious-disease presumptions, benefit calculations, and deadlines vary significantly by state and change over time — confirm the current rules and deadlines with your state's workers' compensation agency or board, or with a licensed attorney in your state.
