Severe Human Case of Zoonotic Infection with Swine-Origin Influenza A Virus, Denmark, 2021

In human case-patients, the first-choice therapy is to remove the worms mechanically by flushing the conjunctival sac with sterile physiologic saline under local anesthesia (Appendix reference 12).From a therapeutic and epidemiologic standpoint, it is important to differentiate between infectious and allergic conjunctivitis.Furthermore, diagnosis can be difficult because immature larvae can hide in the excretory ducts of the lacrimal glands (7).Our findings indicate the need for education and raised awareness about this infection especially for ophthalmologists.Early and adequate diagnosis can help to prevent complications such as corneal ulceration.
