The health officials of Canada and of the US have raised concern over the increasing cases of whooping cough. It has been found that the contagious cough is affecting adults in large numbers. The infected adults are posing high risk to the infants.

Last week, a toddler succumbed to death after being affected with whooping cough. The parents of the deceased child are now urging parents with infants to get their children vaccinated.

Dr. Allison McGeer from Toronto's Mount Sinai Hospital said that whooping cough can be fatal if children are not vaccinated timely. She said, "All diseases have cycles and we're coming up to a peak in pertussis". In the regions of Canada, the cases of whooping cough are being continuously reported since November, 2011.

The other name of whooping cough is pertussis. It has come to light that after every two to five years, the disease returns to the infected region aggressively. On 17th of July, 1,024 cases of whooping cough have been confirmed.

The authorities are required to work closely to make sure that kids are saved from the deadly disease. Besides, parents are being advised to get their children vaccinated, timely.
