Assessment of Healthcare Professionals’ Infection Prevention and Control (IPC) Knowledge and Practices in Handling Scabies Outbreak
This cross-sectional study of 346 healthcare professionals in Rohingya refugee camps reveals that while knowledge of scabies transmission is high, actual infection prevention and control practices remain suboptimal due to barriers such as poor environmental controls and lack of resources, highlighting the critical need to strengthen training, ensure guideline availability, and improve access to protective equipment.

In the crowded, resource-limited settings of refugee camps, a tiny, invisible parasite can trigger a massive public health crisis. This parasite is the scabies mite, a microscopic creature that burrows under the skin to lay eggs, causing intense itching and painful rashes. While the mite itself is small, the disease it causes spreads rapidly when people live in close quarters, sharing beds and clothing. In these environments, the people tasked with stopping the spread are the health workers: the doctors, nurses, and assistants who examine patients and provide care. Their ability to recognize the disease early and follow strict safety rules is the primary line of defense. However, knowing the rules on paper is not the same as following them in a busy, chaotic clinic. Researchers have long wondered if a health worker's knowledge of a disease actually translates into the daily actions that keep a community safe, or if other factors like a lack of supplies or unclear instructions get in the way.
A team of researchers set out to answer this question within the Rohingya refugee camps in Cox's Bazar, Bangladesh, where scabies has been a persistent and severe problem. They focused on 346 health professionals working in various clinics across the camps. These workers included doctors, nurses, medical assistants, and laboratory technicians, all of whom had been working in the camps for at least six months. The researchers wanted to see what these workers knew about scabies, how they said they behaved when treating patients, and what barriers stood between their knowledge and their actions. They did not just ask if the workers knew the symptoms; they asked about specific, difficult parts of the job, such as identifying a severe form of the disease called crusted scabies, tracing who else might be infected, and cleaning the environment to stop the mites from spreading.
The study revealed a complex picture of competence and challenge. When asked about the basics, the health workers were quite knowledgeable. More than 90 percent correctly identified how the disease spreads and what causes it. However, the knowledge became less certain when the questions got more specific. Only about two-thirds of the workers could correctly identify the severe, crusted form of the disease or understand the complications that can arise from it. Similarly, while most knew the disease existed, fewer than three-quarters knew the correct steps for tracking down and treating the contacts of an infected person. This gap in specialized knowledge matters because crusted scabies is highly contagious and can spark large outbreaks if not handled with extreme caution.
When the researchers looked at what the workers actually reported doing, the results showed a mix of good habits and significant weaknesses. About 60 percent of the workers said they had good practices for preventing infection, such as washing their hands and using protective gear like gloves and gowns. They were particularly good at teaching patients about the disease. However, a major weakness emerged when it came to the environment. The workers were much less consistent in cleaning the rooms, bedding, and clothes that might harbor the mites. This is a critical oversight, as the mites can survive on fabrics and furniture, continuing the cycle of infection even after a patient is treated. The study found that while knowledge and practice were linked, the connection was not perfect. Many workers who knew the right answers still failed to perform the right actions, suggesting that knowing the theory is not enough to guarantee safety in the field.
The researchers then investigated why this gap existed. They found that the presence of written guidelines made a tangible difference. Workers who had access to clear, written instructions on how to manage scabies were significantly more likely to follow good practices. Training also played a massive role. Those who had received specific training on scabies were far more likely to practice good infection control than those who had not. Interestingly, the study found that having more years of experience or working in the camp for a longer time did not automatically make a worker better at preventing infection. The most powerful factors were having the right training and having the right tools available. A large portion of the workers reported that a lack of resources, such as a shortage of protective equipment, was a major barrier to doing their jobs correctly.
Ultimately, the study suggests that solving the scabies problem in these camps requires more than just teaching health workers about the disease. It requires building a system that supports them. The findings indicate that even well-informed workers struggle when they lack clear instructions, protective gear, or the time to clean the environment properly. The researchers conclude that to stop outbreaks, health systems must move beyond simple education. They need to ensure that written guidelines are available and easy to find, that training is regular and specific, and that the necessary supplies are always on hand. By addressing these practical barriers, the health workers in the camps can better protect themselves, their patients, and the wider community from the relentless spread of scabies.
