Brown spider (Loxosceles sp.) bite and COVID-19: A case report

Does Covid-19 influence the dynamics of envenomation by animals in a country strongly affected by both conditions? Epidemiological data from Brazil

The impact of Covid-19 on envenomations by venomous animals in countries heavily affected by both conditions has not been quantified yet. Brazil shows high incidence of envenomations by scorpions, spiders and snakes and was heavily affected by waves of Covid-19. To determine how the pandemic impacted the epidemiology of envenomations by those three groups of venomous animals, we used online databases from two surveillance sources on number of cases and mortality. During the years before and during the pandemic, scorpion stings typically occurred in adults of both sexes in urban zones in the Southeast and Northeast regions. Spider bites occurred mainly in the South region, in adults of both sexes in urban zone. Snakebites affected mainly rural adult men in the Amazon. Between 2007 and 2021, overall incidence of cases by scorpions, spiders and snakes decreased after the beginning of the pandemic, snakebites did not show changes after the pandemic started in Brazil, but cases by scorpions and spiders decreased. No changes in the incidence of deaths were observed. On national level, Covid-19 affected some demographic, clinical and epidemiological aspects in cases by scorpions, spiders and snakes.

Massive dermal ulcerative lesions due to brown recluse spider bite: a rare case report and review of literature

A brown recluse spider (BRS) bite is challenging to confirm, but may be clinically diagnosed by considering the location, the season of the year, and the clinical manifestations. Here, the case of a 26-year-old male who presented after an insect bite with a skin lesion, bruising, severe swelling, and diffuse blisters on the right lower extremity after three days, is described. Following clinical examination, patient history assessment, and consideration of other relevant factors, the patient received a differential diagnosis of necrotizing fasciitis caused by BRS bite. Although spider bite poisoning is rare, proper diagnosis and management are important because, in some cases, the outcomes may be devastating.

Massive dermal ulcerative lesions because of brown recluse spider bite: a rare case report and review of literature

A brown recluse spider (BRS) bite is challenging to confirm, but can be clinically diagnosed by considering the location, the season of the year and the clinical manifestations. We described a 26-year-old male who presented after a BRS bite with a skin lesion, bruising, severe swelling and diffuse blisters on the right lower extremity after 3 days. This case should be considered in the differential diagnosis of necrotizing fasciitis. Although spider bite poisoning is rare, proper diagnosis and management are important because, in some cases, it can have devastating outcomes.
