If you click through, you'll find a number of publications in PDF; the issue for May 25 is a forecast of various diseases anticipated for June, one of Cuba's rainiest months. On page 166 is a table showing the numbers for various diseases in the previous week and cumulatively for the year so far.
Seventh from the top you'll find "Enf. Diarreicas Agudas"—acute diarrheic illnesses. It shows 11,642 cases for the preceding week and 199,837 for the year so far—not as bad as 2012, but still a pretty dramatic number. Not a single cholera case is listed for either year, though the Cubans did grudgingly admit they had a few last year.
In the June 1 issue, p. 176, you'll see that another 12,388 cases were recorded in the last week of May, bringing the cumulative total for the first half of 2013 to 212,225.
Obviously cholera is an acute diarrheic illness, but even without its being camouflaged in these numbers, Cuba obviously has a problem. Over 200,000 cases in six months reflects very dubious hygiene and sanitation, not to mention water safety.
