World War I, and to a lesser extent, World War II, brought soldiers all over the world and then back home. The Spanish Flu pandemic is the most severe result of these transmissions.

That's correct!

Other good answers:
• New transportation technology like airplanes
• Poor hygiene
• Misunderstanding of scientific principles of disease transfer
• War
• Poverty/poor living conditions

Your turn.

Campylobacter seems more like a foodborne illness, but everything else is OK. There's also Guinea Worm Disease, which is quite important because it's approaching global eradication.

It's also transmitted through water as well, and I always find it so cool how certain diseases are eradicated, it's like humans winning the war against the disease :D .

[b]cutaneous anthrax[/b] is spread through contact through the skin, generally through lesions or open cuts that allow anthrax spores into the body. Cutaneous anthrax affects the skin and the area around the site of infection.
[b]gastrointestinal anthrax[/b] is spread through eating undercooked or raw meat infected with anthrax. Generally, it affects the upper GI tract and often spreads to the stomach and intestines.
[b]inhalational anthrax[/b] is spread through the inhalation of anthrax spores. It starts with lymph nodes in the chest and then spreads through the respiratory system, often causing breathing problems.
