The coronavirus pandemic is sweeping the globe with an estimated 108 million cases worldwide. (Source) Symptoms of COVID-19 — the disease caused by the SARS CoV-2 virus that emerged in 2019 — may appear 2 to 14 days after exposure to the virus and differ from person to person. Possible symptoms include:

  • Fever
  • Chills
  • Cough
  • Shortness of breath
  • Difficulty breathing
  • Fatigue
  • Muscle and body aches
  • Headache
  • Loss of taste or smell
  • Sore throat
  • Nasal congestion
  • Runny nose
  • Nausea
  • Vomiting


The pandemic has brought up questions of how lupus (systemic lupus erythematosus, or SLE) affects the risk of contracting the coronavirus, whether lupus should be considered a serious underlying health condition in COVID-19 vaccine allocation guidelines, and how individuals with lupus can maintain their health and safety.

What Is Lupus?

Lupus is a long-term, chronic autoimmune disease in which the immune response goes into hyperdrive and produces autoantibodies. These auto, or self, antibodies attack healthy tissues, causing inflammation, swelling, and damage. Symptoms include fatigue, joint pain, rash, and fever. Periodically, symptoms can become more severe; this phenomenon is referred to as a lupus flare-up. (Source, Source)

There is currently no cure for lupus, so treatments primarily focus on improving quality of life by controlling symptoms and minimizing the frequency and severity of flare-ups. Therapies and medications such as immunosuppressants, anti-inflammatories, and steroids may also be helpful. (Source, Source, Source

Lupus and Risk of COVID-19 Infection

Some experts believe that people with lupus are at greater risk of infection with viruses like COVID-19, and may be more likely to suffer severe complications if they do contract a virus. (Source) Because lupus is an autoimmune disorder, it may alter the immune system's ability to effectively fight off the coronavirus.

Some people with autoimmune disorders are more susceptible to pathogens because their immune system is focused on targeting their own tissues. For others, however, a hyperactive immune system may help prevent illness. (Source, Source)

Overexpression of ACE2 in lupus is implicated

The SARS-CoV-2 virus infects a cell by binding to a protein found on the cell’s outer membrane called angiotensin-converting enzyme 2 (ACE2). Studies of the correlation between SARS-CoV-2 and rheumatic disease suggest overexpression of ACE2 in lupus may be connected with increased susceptibility to infection with COVID-19. (Source) However, further research is needed to confirm a causal relationship between overexpression of ACE2 in lupus and infection with COVID-19.   

What the research shows about lupus and COVID-19 risk

There have been few studies specifically looking at the effects of COVID-19 on individuals with autoimmune diseases or those taking immunosuppressant drugs. Reports of other coronaviruses causing pneumonia in immunocompromised patients, however, suggest people with lupus may be at a greater risk of developing respiratory complications from COVID-19. (Source)

Furthermore, in patients with lymphopenia, a condition characterized by low levels of white blood cells that is common in individuals with lupus, a low blood lymphocyte percentage increased COVID-19 severity. (Source, Source) Thus, lupus may increase vulnerability to COVID-19 infection and to serious complications.

Studies on lupus and COVID-19 risk are not conclusive

In contrast, however, two studies published July 2020 in Arthritis and Rheumatology found that patients with lupus and another rheumatic disease, inflammatory arthritis, faced no greater COVID-19 risk than the general population. Immunosuppressants prescribed for the autoimmune conditions also did not significantly change the risk for more severe COVID-19 outcomes. (Source, Source

However, these studies used small sample sizes that may not represent the whole population. Further research should be done involving larger, more diverse sample sizes to determine the relationship between lupus and the risk of COVID-19 infection.

COVID-19 Vaccination for People With Lupus

The Centers for Disease Control and Prevention (CDC) Advisory Committee on Immunization Practices informs recommendations on COVID-19 vaccine allocation. The group suggests vaccines be prioritized for:

  • Health care and essential workers
  • Individuals who live in nursing homes or assisted living facilities
  • People aged 65 years or older
  • Those with underlying health conditions 


COVID-19 vaccination plans based on CDC guidelines differ slightly by state, but lupus may be considered an underlying medical condition and allow lupus patients to receive the COVID-19 vaccine in the early phases of vaccine allocation.

COVID-19 vaccines recommended for people with lupus

Leading infectious diseases experts, such as Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Disease, say that immunocompromised people should get vaccinated when they have the opportunity. (Source) Immunocompromised people are at risk of complications or vaccine-related disease if they receive certain live vaccines, such as the measles, mumps, and rubella vaccine. (Source) However, the Pfizer and Moderna COVID-19 vaccines do not contain live virus, so it is safe for immunocompromised people to get vaccinated unless they have a severe allergy to one of the vaccine’s ingredients.

Can Lupus Drugs Treat COVID-19?

Chloroquine and hydroxychloroquine, two medications used to treat autoimmune diseases such as lupus, were sensationalized by the media and public figures as cures or miracle-workers for COVID-19. However, they have not been found to improve or eliminate COVID-19 symptoms. (Source)

Scientists found that chloroquine and hydroxychloroquine are likely ineffective in treating COVID-19. Further, patients treated with chloroquine and hydroxychloroquine experienced severe cardiac adverse events and other detrimental side effects. (Source)

The FDA has not approved lupus drugs for COVID-19

In June 2020 the United States Food and Drug Administration (FDA) revoked the emergency use authorization it had issued earlier allowing chloroquine and hydroxychloroquine to be used to treat certain approved COVID-19 patients. (Source)

The risks of treating COVID-19 with chloroquine and hydroxychloroquine outweigh the known and potential benefits of their use, and these lupus drugs cannot, at least for now, be used for this purpose.

How to Stay Safe

Regardless of how lupus alters the risk of COVID-19 infection, for now, it’s best to continue following the CDC’s safety guidelines:

  • Get vaccinated as soon as you can
  • Wear a face mask when you can’t avoid contact with others
  • Wash your hands frequently with soap and water or use hand sanitizer
  • Continue social distancing
  • Stay at home except when running essential errands

Connections Between COVID-19 and Lupus

Studies on the connections between covid-19 and lupus are inconclusive and more research is needed to determine their relationship.
