One of the most common problems noticed when a new disease emerges and the scientific community races to study it is the problem of under reporting. Under reporting in disease research can be seen at the case-reporting level (when local doctors incorrectly diagnose a disease and do not alert the proper authorities) or at a larger level, where whole countries do not properly understand and report the prevalence with a disease.

Under reporting can have serious consequences in infectious disease research because when scientists need to understand the severity of a disease, they will be unable to get an accurate and true picture. In the current Zika Virus outbreak in South America, one of the major problems being seen is the lack of accurate records as to the prevalence of microcephaly in children before the Zika outbreak. Scientists want to examine if there truly are more cases of microcephaly now than before, but the lack of records is proving to make the task difficult to complete.

Another example of where under reporting is proving to be a problem is in the study of Melioidosis, also known as Whitmore’s disease. Many people have never heard of this disease, (I haven’t heard of it before writing this post!!) but it is one of the most prevalent diseases spreading through many developing nations, such as India, Brazil, and other tropical areas. Melioidosis is caused by a shape-changing bacteria in contaminated soil and water, and it can infect both humans and animals. A new study, published in Nature Microbiology, estimates that this disease is under reported in 45 countries where it is known to exist, and is present in 34 more countries that do not report it yet. This is a serious problem because Melioidosis can be fatal within 48 hours of symptoms occurring. In these developing nations, where access to healthcare is limited and people live very close to one-another, this under reported disease can cause a serious problem in the future.
