The California Department of Public Health announced that there have
been 4,017 confirmed, probable and suspect cases of whooping cough
(pertussis) reported in the state so far this year, up to September 14 -
a state rate of 10.3 cases per 100,000 people. The number of weekly
reported cases has dropped slightly recently, with 183 new cases this
week and 234 cases the week before.
The last time so many cases were reported was in 1955, with 4,949 cases. The current incidence of whopping cough is the highest since 1962, when it reached 10.9 cases per 100,000 people. The previous peak in total reported cases was in 2005 (3,182 cases).
Of the reported cases, health authorities say 65% are confirmed, 20% are probable and 15% are suspect.
Authorities say 11.2% of infected patients have been hospitalized. 57% of those hospitalized were infants (vey young babies).
Of the 9 deaths reported so far:
The incidence of whooping cough (pertussis) is highest among babies aged up to six months - 184 cases per 100,000; in children aged 7-9 years - 33 cases per 100,000; and adolescents aged 10-18 - 24 cases per 100,000.
Most adolescent cases are aged 10 or 11 years.
After fits of several coughs, the whooping cough patient will often need to take deep breaths which can make a whooping sound. Pertussis coughing fits can last for up to 10 weeks or more; hence its nickname, the 100 day cough.
Infants and young children are especially susceptible to complications of whooping cough. Very young babies are more vulnerable to the fatal complications of the diseases.
The best way to protect yourself form pertussis is to take the vaccination. There are vaccines for children, teens and adults. The childhood vaccine is called DTaP, while the booster vaccine for adolescents and adults is called Tdap.
According to the CDC (Centers for Disease Control and Prevention), there are 30-50 million cases of pertussis and about 300,000 deaths per year worldwide.
Since the 1980s, the number of reported cases of pertussis in the USA has been increasing, especially among 10-19 year olds and infants aged less than 6 months.
Over 50% of babies less than 1 year old who become infected need to be hospitalized.
