Purpose of review
The global significance of cryptosporidiosis is widespread and far-reaching. In
this review, we present recent data about strain diversity and the burden of disease,
along with developments in therapeutic and preventative strategies.
Recent findings
Cryptosporidium is an emerging pathogen that
disproportionately affects children in developing countries and immunocompromised
individuals. Without a diagnostic tool amenable for use in developing countries the
burden of infection and its relationship to growth faltering, malnutrition, and
diarrheal mortality remain underappreciated. Disease incidence is also increasing in
industrialized countries largely as a result of outbreaks in recreational water
facilities. Advances in molecular methods, including subtyping analysis, have yielded
new insights into the epidemiology of cryptosporidiosis. However, without practical
point-of-care diagnostics, an effective treatment for immunocompromised patients, and a
promising vaccine candidate, the ability to reduce the burden of disease in the near
future is limited. This is compounded by inadequate coverage with antiretroviral therapy
in developing countries, the only current means of managing HIV-infected patients with
cryptosporidiosis.
Summary
Cryptosporidiosis is one of the most important diarrheal pathogens affecting
people worldwide. Effective methods to control and treat cryptosporidiosis among high
risk groups present an ongoing problem in need of attention.
