This represents an 18% increase compared to the provisional numbers that were reported at the same time in 2013. The final case count in 2013 was 28,639.
Age-incidence trends observed during 2014 were similar to those in 2013 and 2012. Increased rates were again observed in adolescents 13 through 15 years of age, as well as in 16 year old's.
Overall reporting of pertussis declined during 2013 after a peak year in 2012. During 2012, 48,277 cases of pertussis were reported to CDC, including 20 pertussis-related deaths. This was the most reported cases since 1955. The majority of deaths occurred among infants younger than 3 months of age. The incidence rate of pertussis among infants exceeded that of all other age groups. The second highest rates of disease were observed in children 7 through 10 years old. Rates increased in adolescents 13 and 14 years of age.
Symptoms of the whooping cough .
Where did the disease originate.
whooping cough can cause serious illness in infants, children and adults. The disease usually starts with cold-like symptoms and maybe a mild cough or fever. After 1 to 2 weeks, severe coughing can begin. In infants, the cough can be minimal or not even there. Infants may have a symptom known as "apnea." Apnea is a pause in the child's breathing pattern. Pertussis is most dangerous for babies. About half of infants younger than 1 year of age who get the disease are hospitalized.
How did it spread.
Whooping cough spreads easily from person to person through coughing and sneezing. Unfortunately, some people who spread whooping cough may not know they have it. Kids usually catch whooping cough by breathing in tiny droplets that are released into the air by other people's coughs and sneezes.
What does this say about the country.
The Washington State Secretary of Health Mary Selecky has declared whooping cough is at epidemic levels and requested federal assistance. Washington has counted 1284 cases since the beginning of the year, ten times the number of cases at this time in 2011.
Wisconsin has also recorded nearly ten times the number of cases as last year, with nearly 1900 cases. In particular, Dane County reports 253 cases, more than the last four years combined. Montana has its own flood of cases in several different counties. No deaths have been reported in Washington, Wisconsin, or Montana.
how a major outbreak of this disease (an epidemic or pandemic) could affect a countries government.
pertussis were reported to CDC during 2014, and this number is expected to increase as case counts are reconciled. This represents an 18% increase compared to the provisional numbers that were reported at the same time in 2013.
