SAN FRANCISCO, June 16 Public health officials
warn that whooping cough poses the greatest risk to young
children as California deals with its worst outbreak of the
respiratory disease since 2010, with nearly 3,500 reported
victims so far this year.
"Prevention of pertussis is particularly important in young
infants because they are the ones at risk for severe disease and
death," Dr. Gil Chavez, state epidemiologist and deputy director
of the California Department of Public Health, said on Monday.
Infants, in particular, are the most vulnerable to the
disease which causes severe, uncontrollable spasms of coughing
that can make breathing difficult, and public health officials
urged parents to make sure their youngsters are properly
Vaccines also are recommended for pregnant women and adults
who have increased contact with young children.
California public health officials said on Friday whooping
cough, also known as pertussis, has reached epidemic proportions
in the state.
More than 800 cases have been confirmed statewide in the
first two weeks of June alone, with Napa, Sonoma and Marin
counties near San Francisco Bay reporting the highest rates of
infection per capita.
The highly contagious bacterial infection strikes 30 million
and 50 million people each year worldwide and kills about
300,000 annually, mostly children in the developing world.
In the United States, where outbreaks tend to run in cycles,
most children are immunized against pertussis with a vaccine
given as a series of shots beginning as early as six weeks of
age. Pregnant women should get the vaccine in their third
trimester because antibodies will be passed on to their
newborns, Chavez said.
Pertussis in young children usually begins with a runny nose
and occasional coughing for up to two weeks, escalating into
bouts of intense coughs punctuated with a characteristic
Infants typically do not exhibit the classic symptoms but
may gag or gasp, and their faces may turn red or purple during
those spells, Chavez said.
As of June 10 of this year, 3,458 cases of pertussis have
been reported throughout California, far surpassing the 2,530
people diagnosed with the disease statewide for all of 2013.
Of this year's tally, 119 patients have been hospitalized,
most of them under four months of age, and one, a 5-week-old
infant, has died.
This year's outbreak so far pales in comparison to a
whooping cough epidemic that struck California in 2010, when
9,000 cases, including 10 infant deaths, were reported.
