Some of these small parasites have been mutating and are now resistant to many over-the-counter medications.
Huge crowds are once again converging on Tahrir Square in Cairo on the one year anniversary of the uprising that ousted longtime President Hosni Mubarak from power.
The BBC’s Jon Leyne says the demonstration has the feeling of a street party and there are more people in the square than last year because more groups are convening– from liberals, to once-banned Islamists who won a majority of parliamentary seats in recent elections, to the country’s current military rulers want to claim ownership of the revolution.
Earlier this week members of Egypt’s new parliament took their seats for the first time, and only a handful of women were elected.
29-year-old Dalia Ziada ran for Parliament but didn’t win. She is a human rights activist from Egypt and a passionate advocate for women’s rights.
And as director of the American Islamic Congress’s Egypt Bureau, she translated a 1950s American comic book about Martin Luther King Jr. into Arabic, coining the Arabic word for “non-violence” that has now come into common usage in Egypt.
