Take Caution during COVID-19: Potential Rare Symptoms

The most common symptoms for COVID-19 include:

  • Fever or chills, cough, shortness of breath (or difficulty breathing), fatigue, muscle or body aches, headaches, new loss of taste of smell, sore throat, congestion or runny nose, nausea or vomiting, and diarrhea. 

More severe symptoms of the virus include:

  • Breathing difficulty, chest pain or pressure, new confusion, inability to wake or stay awake, and bluish lips or face. 

However, in addition to the more commonly reported symptoms above, healthcare professionals are noticing an increase in reporting for rare symptoms that are not currently on the CDC symptom list. These can include, but are not limited to:

  • More gastrointestinal symptoms: In addition to commonly reported nausea, vomiting, and diarrhea, some may experience a loss of appetite.
  • Skin rashes: Increasing reports of skin rashes have been associated with COVID-19 patients. Some individuals have reported a red, patchy rash, while others report hives or a “chickenpox-like” rash mostly affecting the hands and feet. 
  • “COVID Toes”: This is also a rash-like symptom that is being seen more often with COVID-19 cases. “COVID Toes” refers to a noticeable red, purple, or pink discoloration of the tips of the toes. This symptom can occur after the infection has already passed. 
  • Eye-related issues: Enlarged red blood vessels, swollen eyelids, excessive watering of the eyes, increased discharge, and light sensitivity may be associated with COVID-19. 
  • Blood clots: Inflammation and infections are known to increase one’s risk of clotting. However, doctors and studies are seeing a high percentage (potentially 30-40%) of hospitalized COVID-19 patients experiencing blood clots. If you are at risk for blood clotting, be sure to take your blood thinning medication as directed.
  • Delirium: This symptom is almost exclusively seen among the elderly and can be coupled with disorientation and falls, incoherence and speech issues, and severe confusion.
  • Hearing Loss: Some evidence demonstrates that hearing loss or tinnitus is associated with COVID-19, but more research is needed to reach any conclusions.

At this time, more data and scientific evidence is necessary to determine whether or not these symptoms are specific to COVID-19, but it is a good idea to pay attention to any unusual health issues that you are experiencing.  

COVID-19 symptoms usually develop between 2-14 days after exposure. If you are experiencing symptoms, it is a good idea to get tested and if your symptoms are severe, call your doctor.

The University of Arizona is conducting a long-term study to examine the long term effects of the virus, for more information visit this link.
