CDC data reveals why everyone around you is coughing

Whooping cough, also known as whooping cough, is making a comeback that no one asked for.The latest federal data shows that cases of the vaccine-preventable disease have reached their highest level in a decade.

As of December 14, 32,085 cases of whooping cough have been registered reports The US Centers for Disease Control and Prevention That’s a five-fold increase from just 6,500 cases in 2023. Experts say several factors are to blame for the increase, including declining vaccination rates.

whooping cough caused by bacteria Bordetella whooping cough. The infection usually causes respiratory symptoms, especially the coughing fits that inspired its nickname (“snoring” refers to the noise people often make when they try to breathe after coughing.) Although whooping cough is usually mild in adults, the infection may be more serious in young children or other vulnerable groups such as people with weakened immune systems.

Meanwhile, the first whooping cough vaccine was invented more than a century agoIt was not widely recommended and used until the late 1940s, when it was combined with the tetanus and diphtheria vaccines. Since then, the combination vaccine has been the mainstay of immunization programs in the United States, and it has greatly helped reduce the burden of pertussis. before mass vaccination, there were 100,000 to 300,000 cases of whooping cough; reports annually in the USA

The US has had tens of thousands of rare cases of whooping cough each year since 2000. But as with many infectious diseases, the Covid-19 pandemic has indirectly reduced the spread of whooping cough, in part because the world and people’s social habits have largely returned normal, cases of these diseases have also increased. So at least part of this year’s increase in cases may simply be a return to pre-pandemic trends. According to the CDC.

That said, this year’s figure is unusually high for modern times. It’s the highest number of cases since 2014, when 32,971 cases were reported blame reducing vaccination rates among residents and their children for growth.

Another important factor concerns the vaccine itself. In the US and many other countries, people have switched to a newer, different form of the pertussis vaccine the vaccine is safer than the older, whole-cell version, evidence has shown that it provides less immediate and sustained protection against whooping cough overall as a result of this disconnection: experts argued that future outbreaks of whooping cough are likely to be larger when they occur.

However, vaccination remains the most important tool to control whooping cough, and the fewer people vaccinated against it, the greater the risk of persistent outbreaks the reasons 2.4 million cases per year, as well as 161,000 deaths per year in children under five.

About 80% of children in the US under the age of two have it received With the full DTaP vaccination series recommended, 90% of adolescents have received at least one Tdap vaccine, and only 43% of adults over 18 have received a Tdap vaccine in the past ten years (boosters are recommended every decade).
