A sting from a fire coral can trigger uncomfortable symptoms. It is important to note that fire corals are not actual corals and more directly linked to jellyfish and other anemones that sting. You can spot fire corals due to their distinctive bright yellow-green and brown skeletal covering in tropical and sub-tropical waters.
In most cases, these organisms inflict localized pain that is described as burning or stinging and possibly a rash.
The miniature cnidoblast on the fire corals include tentacles that bulge from several surface pores. Additionally, they have a sharp, solidified exterior skeleton that can brush on the skin.
What are the signs of a fire coral sting or cut?
- Within 5-30 minutes of contact with the fire coral, it can trigger an immediate burning sensation or stinging pain.
- A reddened rash with elevated wheals or vesicles form along with itchiness.
- Enlarged lymph glands might occur after some time.
- Nausea and/or vomiting has been reported in some cases.
If an individual sustained a cut from a fire coral, it is treated in the same manner as any wounds from corals.
Management
- The site of the sting or cut must be rinsed with seawater. Do not use freshwater since it can intensify the discomfort.
- Dab on a topical acetic acid or isopropyl alcohol to deactivate the venom.
- Get rid of any leftover parts of the fire coral using tweezers or with tape after the site has been treated with acetic acid or isopropyl alcohol. This helps remove the toxin or venom that triggers the symptoms.
- The affected extremity must be immobilized since movement can cause the venom to spread.
- Apply hydrocortisone cream 2-3 times daily as needed to reduce the itchiness.
In case an individual who was exposed to the fire coral starts to experience shortness of breath, swollen face, tongue or throat or other signs of an allergic reaction, the individual must be treated for an allergic reaction.
If there are no signs of an allergic reaction, the pain can be relieved with pain medications such as acetaminophen.
