NOVEL CORONAVIRUS: Allergen or Not An Allergen?

Not An Allergen

NOVEL CORONAVIRUS (SARS-CoV-2)

Please note that this page is a summary of what we currently know about novel coronavirus, COVID-19, and skin concerns. As of the time of this writing, skin lesions were beginning to be described in COVID-19. Avoiding rashes and other skin problems from the irritants and contact allergens described below is important as they may be mistaken for the skin lesions of COVID-19. Because the virus is new and the understanding of it is evolving rapidly, this page may quickly become outdated. Refer to trusted sources such as the World Health Organization, Centers for Disease Control and Prevention, and your country’s department of health for up-to-date information about COVID-19.
Novel¬†coronavirus caused a global pandemic, fear and uncertainty, economic instability, sickness, and death…but it is not a contact allergen.¬†While it would never be¬†on patch test trays,¬†COVID-19 does teach us a few important things about how a pandemic can affect the skin and especially sensitive skins.
The¬†virus is not dermatotropic (a virus that affects or is attracted to the skin)¬†but its contagiousness has meant a necessary increase in more aggressive personal hygiene and disinfection, and an increase in¬†contact with personal protective equipment (PPEs). Many people can suffer irritation and/or contact dermatitis due to the harm that alcohol,¬†detergents and disinfectants can cause¬†the hydro-lipid mantle of the skin. But it is health front liners who bear the brunt of skin issues.¬†According to one¬†study¬†in Clinics and Dermatology,¬†some of the skin concerns suffered by healthcare workers include “Pressure injury, contact dermatitis, itch, pressure urticaria, and exacerbation of pre-existing skin diseases, including seborrheic dermatitis and acne.” The most common skin complications seen are contact reactions ‚ÄĒ redness, burning, itching, barrier problems, scaling, and more ‚ÄĒ from the extended wear of PPEs:

  • Extended wear of gloves can lead to redness and other reactions due to contact dermatitis (especially to rubber or latex gloves) or the sustained exposure to the sweaty environment that the occlusion creates (the gloves create a sealed environment).
  • Hand washing is a concern for everyone but more so for front liners who wash their hands well over ten times a day.
  • Extended wear of goggles and masks in particular (especially with¬†the heat and sweat of exertion and stress) can cause swelling, burning, itching, urticaria, contact dermatitis, and even acne.
  • Head covers and other occlusive equipment can trigger flare-ups of seborrheic dermatitis, folliculitis, and itching.
  • Heat and sweat can cause pressure urticaria. This is not an allergy¬†but¬†a form of physical urticaria.

Dermatologists may need to care for people hoping to prevent infection as well as health front liners who may develop skin complications due to their efforts to stay safe and care for others. Some possible ways to prevent or alleviate symptoms could be to prioritize allergen-free, irritant-free, and non-comedogenic products.

Cleanser:

Hair and body washes like Superwash have the added benefit of cleansing hands, hair, scalp, and body both gently (allergen-free) and thoroughly (contains acceptable concentrations of coconut-derived SLS, which is antimicrobial).

Facial Cleanser:

Now is the time for the gentlest options to offset the friction, occlusion, and allergen-exposure from prolonged use of PPEs.

Moisturizer and Barrier-Protection for Hands:

Apply emollients and barrier protective creams liberally onto hands following hand washing and before wearing PPE equipment.

Skin Calmers:

The Big, Brave Boo-Boo Balm and Red Better Calm-The-Heck-Down Balm provide non-steroidal quick relief and non-irritating disinfection for itching, redness, and lacerations. While steroids may occasionally be necessary, they are contact allergens and prolonged steroid use can worsen the skin and cause other health issues.

Disinfection Techniques with Moisturizing, Film-forming, Barrier-Protective Alternatives:

See another disinfection technique using the products listed above. Based on a review of clinical studies on virgin coconut oil and monolaurin as effective antivirals, antibacterials and antifungals, this technique could give damaged skin some relief and time to heal.

Other Skin Concerns:

Dermatology patients with auto-immune skin disorders with chronic inflammation such as psoriasis, lupus, atopic dermatitis, etc. may also require additional care. Many of these conditions are treated with biologicals which are immune suppressive. Check with your dermatologist on the latest recommendations regarding whether the administration of these biologics needs to be delayed.
It is important to emphasize that, to our knowledge as of this writing, monolaurin has not been tested on SARS-CoV-2 specifically (neither has alcohol). This information is compelling but needs validation on this particular virus. The available evidence seems to suggest similar efficacy to alcohol in destroying enveloped viruses and some coronaviruses. Follow your doctor’s instructions, and rely on trusted sources such as the World Health Organization, Centers for Disease Control and Prevention, and your country’s department of health.

If you have a history of¬†sensitive skin, don’t guess: random trial and error can cause more damage. Ask your dermatologist about¬†a¬†patch test.
