The World Health Organization (WHO) describes COVID-19 as an infectious disease caused by the most recently discovered coronavirus, a family of viruses known to cause respiratory infections in humans. This new virus and disease were unknown until the recent outbreak in Wuhan, China in December 2019 (1).
As of early April, throughout the world, around 3 million cases have been reported. This does not take into account the most likely high number of asymptomatic individuals and carriers.
The most common symptoms are fever, dry cough, flu-like aches, sore throat, fatigue, chest pain, and shortness of breath, and can range from mild to severe.
Most known cases have been mild to moderate and not life-threatening.
Infected persons fall into one or more of the following categories based on severity of symptoms: asymptomatic, mild, moderate, severe, and critical. Further details on asymptomatic and mild cases can be found here. Learn more about what coronavirus symptoms can look like on a day by day basis in the video below:
If you have an autoimmune disease, some of your autoimmune symptoms may mimic those of COVID-19. You may be wondering how to tell them apart. The data is still limited, and there’s no hard and fast rule about which symptoms – like shortness of breath, fever, and fatigue – would signal the virus and which would belong to an autoimmune flare-up.
Experiencing unusual symptoms that may be consistent with COVID-19? Call your healthcare provider. Other options are using the Center for Disease Control & Prevention (CDC) Coronavirus Self-Checker bot, or calling your area’s hotline number (may vary by state, province, region, etc.) for any concerns or questions about what to do in your particular situation.
In the case of emergency warning signs such as difficulty breathing, persistent chest pressure or pain, confusion, or bluish lips or face, the CDC recommends getting medical attention immediately.
If you’ve been exposed to someone with COVID-19, you should watch for symptoms, take your temperature twice a day, stay away from people who are high-risk, and self-quarantine.
Minimizing or eliminating contact with others for a maximum of 14 days (incubation period for the virus is 2-14 days) will ensure that you have not been infected and will not infect others.
The people you have been in physical contact with do not need to be in quarantine. However, if there is a lot of community spread in your area, your local public health officials may advise otherwise (2).
COVID-19 data is limited, and prevalence statistics are difficult to clearly define.
Mortality, hospitalization, and other rates may be lower than implied, due to the lack of testing and strong indications that asymptomatic carriers and mild, undocumented occurrences account for more of the total coronavirus cases than previously thought (24, 25, 26, 27). However, testing is imperfect and no one study or estimation will give us the all answers – there is still much to learn.
For a clearer picture of what the pandemic looks like in your particular country or region, stay informed through your local public health department.
If you’re also concerned about the rapid spread of misinformation, check out WHO’s list of coronavirus mythbusters.
High-risk individuals include those over age 60, and anyone with altered or compromised immune systems or underlying health conditions such as HIV, diabetes, obesity, heavy smokers, cancer, lung and heart disease, asthma, and other respiratory conditions.
The high-risk category can also include many autoimmune diseases or chronic inflammatory conditions (as infections can cause severe flares), and especially individuals treated with immunosuppressants, corticosteroids, or chemotherapy.

Many people with autoimmune disease are likely to be high-risk, but some may not be. Certain autoimmune conditions may also be more susceptible to contracting the virus or developing severe symptoms than others. As we are still learning about this virus, there is simply not enough information out there to know for sure.
At the end of the day, your personal risk depends on your unique situation, any medications you’re taking, if your disease is under control, and if you have multiple conditions. It is a determination to be made by both you and your doctor.
Whether you think you may be high-risk or not, physical distancing (more commonly known as social distancing) and heeding the advice of doctors and public health officials are absolutely critical. These efforts help to prevent high-risk individuals from becoming infected and from experiencing serious symptoms in a further effort to stem the flood of new cases in hospitals.
A Note on Face Masks
The CDC now urges the use of cloth face covers when in public settings, regardless if you’re symptomatic or not.
Face masks are critical barriers for those who are sick with COVID-19, their caregivers, and healthcare workers. As many cities are dealing with mask shortages, the CDC advises against the purchase of surgical masks or N-95 respirators for the general public. This saves them for use in hospitals, where the risk of infection is especially high (3).
As an alternative, use a bandana or cloth from an old t-shirt to cover your nose and mouth. This is especially important in indoor spaces where physical distancing is more difficult, as well as in areas where there is strong community spread of the virus.
While they are not a surefire way of completely filtering the air, cloth face covers do help to protect against fluids from coughing, sneezing, and speaking, and are another vital tool in slowing the spread of the virus.
Cancelling events, closing businesses, washing hands often and disinfecting surfaces, staying home, and wearing a mask will slow down the rate of the epidemic.
Physical (or social) distancing is an especially vital tool epidemiologists employ to control outbreaks like COVID-19. This practice minimizes the risk of spreading the infection to immunocompromised individuals and of overwhelming the healthcare system.
If proper measures aren’t taken, hospitals can be bombarded with a swarm of new patients all at once, in addition to their current caseload. This means slower, lower quality care for individuals with the virus, as well as those with other serious conditions like autoimmune disease and cancer.
We’re encouraged to practice physical distancing not only to flatten the curve, but also to stop the spread. The graphic below explains how our attitudes and actions can help or hurt this situation.
Our fears about this unprecedented situation are 100% valid; however, they drive us to overreact in the hope of maintaining control – overbuying groceries, supplements, and supplies, obsessively sanitizing, holding our breath around others, letting our thoughts be consumed by coronavirus “what if’s”… It’s natural to feel this way, but it’s important to recognize when we’re tumbling into a panic.
Elevated stress, anxiety, and fear can keep our bodies in “fight or flight” mode. Research studies have repeatedly demonstrated the effects this state of being can have on our bodies – including our immune systems. The impacts of stress are especially important to all individuals with chronic conditions like autoimmune disease. A healthy stress response is one of many components (including sleep, nutrition, nature, social interaction, and emotional support) essential to controlling symptoms and keeping conditions stable.
There is a lot of uncertainty and that’s ok. We can’t do anything about that. What we can do is keep our gaze on the next small step ahead, follow the basic recommendations from public health officials, practice self-care, and simply stay informed.
Head over to Psychology Today for some helpful tips on managing COVID-19 anxieties. You can also call the Helpline from the National Alliance on Mental Illness (NAMI) at (800) 950-6264, or check out their comprehensive guide to navigate concerns like coronavirus anxiety, quarantine and isolation, and loved ones with mental illness.
Note: Always consult your psychologist with any mental health concerns.
The coronavirus pandemic is affecting the health and well-being of high-risk individuals, while simultaneously creating financial and logistical difficulties for families, hourly wage employees, and small businesses, among many challenged populations – not to mention potential economic crises and famine in developing countries all over the world.
During this time, it’s important to stay calm and connected to your support community, help each other, do your part in slowing the rate of infection, and know that we will move on from this crisis.
