today is the first-ever World Chagas Disease Day.
And according to https://en.wikipedia.org/wiki/Chagas_disease,
Chagas disease, also known as American trypanosomiasis,
is a tropical parasitic disease caused by the protist Trypanosoma cruzi.
It is spread mostly by insects known as Triatominae, or "kissing bugs".
In the early stage,
symptoms are typically either not present or mild,
and may include fever, swollen lymph nodes, headaches
or local swelling at the site of the bite.
After four to eight weeks,
individuals enter the chronic phase of disease and in 60–70%,
it never produces further symptoms.
The other 30–40% of people develop further symptoms
10–30 years after the initial infection,
including heart disease in up to 45%
which can lead to heart failure.
Neurological and digestive complications,
including an enlarged esophagus or an enlarged colon,
may also occur in up to 21% of people.
