Unfortunately, prevention methods do not always work. If someone is affected by an infectious disease, it is important for them to seek treatment as soon as possible. The earlier treatment can begin, the quicker an individual can be healed, reducing the potential for the disease to spread to others.

What are some examples of persistent challenges in responding rapidly and effectively to health security threats?
One example of a persistent challenge in responding rapidly and effectively to health security threats is the limited functionality of EOCs. Without well-functioning EOCs, countries’ coordination during an outbreak is at risk. To address this challenge, CDC is working with countries to develop EOC infrastructure, implement sustainable models for EOC operations, and assist with training current and new EOC staff to activate and manage emergency responses.
Why is it important to confirm a diagnosis?
Confirming diagnosis with laboratories allows health workers to respond rapidly with the most effective treatment and prevention methods, reducing spread of disease and deaths. Effective disease surveillance with rapid laboratory diagnosis enables countries to quickly detect outbreaks and continuously respond to potential risks.

However, recent evidence suggests that school closures can help limit exposure to the contagion and mitigate the spread of disease.
Can you infect your classmates with Ebola?
When infected, children are instructed to not attend school, so they do not infect their classmates. However, because the disease is relatively mild, those who are infected can be isolated at home.

Why is it important to investigate an outbreak?
The most important public health reasons for investigating an outbreak are to help guide disease prevention and control strategies. These disease control efforts depend on several factors, including knowledge of the agent, the natural course of the outbreak, the usual transmission mechanism of the disease, and available control measures. For example, if a health department learns of an outbreak of hepatitis A (known agent) in which one of the victims is a restaurant cook, the department can offer immune globulin to the restaurant patrons to prevent a second wave of cases (control measure), but only if they are within 14 days of exposure (timing). On the other hand, if an outbreak appears to be almost over, the health agency may not need to implement control measures, but may be interested in identifying factors that contributed to the outbreak in order to develop strategies to prevent similar outbreaks in the future. For that outbreak of hepatitis A, investigators may find that the poor personal hygiene that led to the outbreak was the result of lack of soap or water in the workplace washroom, which could be addressed in public health messages to other worksites.
What skills do epidemiologists need to investigate an outbreak?
Investigating an outbreak requires a combination of diplomacy, logical thinking, problem-solving ability, quantitative skills, epidemiologic know-how, and judgment. These skills improve with practice and experience. Thus, many investigative teams pair a seasoned epidemiologist with an epidemiologist-in-training. The latter gains valuable on-the-job training and experience while providing assistance in the investigation and control of the outbreak.
