We can't see them, but no matter what we touch in our day-to-day lives, we come into contact with germs.


David Gerow (CBC)

CBC Ottawa's David Gerow uncovered the hidden world of germs and dispelled the myths about what can and can't make you sick.

Germ Wars

Watch David Gerow's special reports this week on CBC TV News starting at 5 p.m.

To accomplish that feat, he enlisted the aid of University of Ottawa microbiologist Jason Tetro, known as the "Germ Guy."

Tetro works out of the Emerging Pathogens Research Centre and the Centre for Research on Environmental Microbiology.

He tested a number of objects we touch on a daily basis including cellphones, shopping carts, hockey bags and a coffee table.

Tetro also answered your questions on the dangers of germ pathogens.

He also took to our pets to see whether they have more or fewer germs than an active young boy.

Kids and germs

Tuesday: Go to the hockey rink and take a look at how your kids might be picking up germs. You will find out what you can do to help them stay healthy and avoid getting sick. Plus, a father, daughter and son check their equipment to see whose equipment is the "germiest."


Pets and germs
