Cryptosporidiosis outbreak in a child day-care center caused by an unusual Cryptosporidium hominis subtype

Absence of Cryptosporidium hominis and dominance of zoonotic Cryptosporidium species in patients after Covid-19 restrictions in Auckland, New Zealand

“…Our data suggest that the national measures for responding to the Covid-19 also interrupted C. hominis transmission. For instance, the closure of all child care centres and schools may have limited C. hominis transmission since these have been linked to previous outbreaks (Goñi et al ., 2015 ). Ongoing managed isolation of visitors or citizens returning to New Zealand since then has also likely reduced new imported cases of cryptosporidiosis.…”

Practical Guidance for Clinical Microbiology Laboratories: Laboratory Diagnosis of Parasites from the Gastrointestinal Tract

“…In addition to being used to study zoonotic and waterborne infection, these methods have been used to study the seasonality of disease, as well as differences in gender and age distributions (254). These tools have been used to study the burden of disease in resource-limited countries and further clarify the relatively high prevalence of disease in patients with HIV and in children in day care centers, in whom transmission readily occurs (255)(256)(257). Although these methods have been useful because of exquisite sensitivity and the ability to genotype the parasites, Frickmann et al recommend caution when interpreting positive signals in highprevalence settings, suggesting that these may be secondary to asymptomatic carriage or residual DNA from previous infections (258).…”

Occurrence of cryptosporidium parvum IIaA17G1R1 in hospitalized hemato-oncological patients in Slovakia

“…Since the 1980s, numerous outbreaks of cryptosporidiosis have been reported in healthcare facilities around the world, including the transmission of the parasites to healthcare workers from immunosuppressed and immunocompetent patients, and between patients (Baxby et al 1983 ; Vandenberg et al 2012 ; Feng et al 2012 ; Goñi et al 2015 ).…”
