Cryptosporidiosis Surveillance — United States, 2009–2010 Cryptosporidiosis is a nationally notifiable gastrointestinal illness caused by chlorine-tolerant protozoa of the genus Cryptosporidium. The total (confirmed and probable) number of cases of cryptosporidiosis reported annually increased 16.9% from 7,656 for 2009 to 8,951 for 2010. Cases were most frequently reported in children aged 1–9 years, followed by adults aged 25–29 years. This is the first reporting period in which more cases of cryptosporidiosis were reported in females than in males. Local and state health departments can use cryptosporidiosis surveillance data to define the epidemiology of cryptosporidiosis in the United States, establish public health priorities (e.g., research) to improve cryptosporidiosis prevention and control, and design and evaluate efforts (e.g., health communication and policy) to prevent and control the transmission of Cryptosporidium. full tex
Giardiasis Surveillance — United States, 2009–2010 Giardiasis is a nationally notifiable gastrointestinal illness caused by the protozoan parasite Giardia intestinalis. During 2009–2010, the total number of reported cases of giardiasis increased slightly from 19,403 for 2009 to 19,888 for 2010. A larger number of case reports were received for children aged 1–9 years than with other age groups. Peak onset of illness occurred annually during early summer through early fall. Local and state health departments can use giardiasis surveillance data to better understand the epidemiologic characteristics and the disease burden of giardiasis in the United States, design efforts to prevent the spread of disease, and establish research priorities. full text
