Infectious diseases have ravaged the globe for centuries and some of them have led to the discovery of new medicines, vaccines and in some cases, preventive measures to keep people healthy. In this video, I focus on the transmission and causative agents of cholera and malaria. I also share some of the measures that have been put in place to address these diseases.
Corrective note: Vibrio cholerae acts on the wall of the small intestine and releases its toxins there.

What is a drug? | Health | Biology | FuseSchool

You may have already watched our video about pharmacology and drugs, but if not, let’s recap. What is a drug? A drug is a substance that when released into the body will cause an effect.

Some are legal, some are illegal and some are prescribed by doctors to treat illnesses. Whether a drug is legal or not, or can be bought without a prescription, varies by country. Recreational drugs are substances that people choose to take, like for example nicotine (in tobacco), alcohol, or coca leaves in the Andes. In this video, you are going to learn about two different types of drugs and their effects on the body.
