The CDC worked 24/7 to help protect Americans from numerous health threats in 2018, ranging measles to antibiotic resistance.
Here are nine health issues the CDC addressed in 2019:
1. E-cigarette, or vaping, product use-associated lung injuries. As of Dec. 10, the CDC has reported 2,409 EVALI cases, along with 52 deaths. The agency made a major breakthrough in November, pinpointing vitamin E acetate as a potential culprit for the vaping-related illnesses.
2. Opioids. The CDC has allocated $301 million to support states' opioid overdose prevention efforts as part of its Overdose Data to Action fund launched in September.
3. Antibiotic resistance. The agency issued its Antibiotic Resistance Threats report in November, which noted deaths linked to antibiotic resistance have decreased 18 percent since 2013.
4. Foodborne outbreaks. This year, CDC officials investigated and resolved more than 75 disease outbreaks linked to food or animals.
5. Pregnancy-related deaths. The agency issued several reports this year on the leading causes of pregnancy-related deaths, along with racial and ethnic disparities in maternal mortality rates.
6. HIV treatment and prevention. In February, CDC and HHS shared a goal to reduce new HIV infections by 90 percent by 2030. The agencies awarded $16.5 million to state and local health departments this year to support these efforts.
7. Measles. As of Dec. 5, the CDC reported 1,276 measles cases in 31 states. This is the highest case count reported since 1992.
8. Low vaccination rates. CDC research highlighted the nation's low vaccination rates for the flu shot and HPV vaccine this year, among other inoculations.
9. Ebola. The CDC has been working with health officials in the Democratic Republic of Congo to help contain the world's second-largest Ebola outbreak in history.
