On several recent occasions, while commenting on the red-hot immigration issue, Lou and company remarked that "there had been 7,000 cases of leprosy in this country over the previous three years, far more than in the past". (Leprosy is a flesh-eating disease prevalent among immigrants, particularly of Asian or Latin American origin.)
When asked about fact-checking, Lou reportedly said: "If we reported it, it's a fact." A quick visit to the government's leprosy program web-site immediately reveals the time-series chart, shown on the left. With annual rates at about 150 in the last 5 years or so, one is hard impressed to find the 7,000 alleged cases!
Furthermore, because this chart lacks comparability, we fail to see that 150 cases out of a population of 300 million represent a minuscule risk.
A slight downward trend is evident in the last 20 years or so; this record is even more impressive when we realize the population grew during this period. These points can be made clearer in multivariate plots.
