A recent study has revealed that wastewater testing can detect the presence of mpox. This method is expected to lead to the identification of more microorganisms in the future.

According to a report released on Thursday by U.S. health officials, analyzing wastewater is effective in identifying cases of mpox, further supporting the use of sewage as a method for monitoring various diseases.

According to a study by researchers at the U.S. Centers for Disease Control and Prevention, there is a 32% chance that tests will identify at least one person infected with mpox in a population of thousands to millions over the course of a week.

Amy Kirby, the individual in charge of the CDC’s tracking of wastewater, stated that at first they were uncertain if the tests would be effective in detecting a less common infection such as mpox.

She mentioned that it ended up being very successful.

As the number of infected individuals increased, the likelihood of detecting infections through testing also increased. In communities with 15 or more infected people, there was a 76% probability that wastewater testing would detect mpox.

The liquid that flows into a sink, shower drain, or toilet may contain small particles of viruses or bacteria from the skin or from being excreted in urine or feces. Research has demonstrated that testing wastewater can serve as an early indicator of a community being affected by an illness, even before medical professionals begin reporting cases.

Joshua Levy, a researcher at the Scripps Research Institute in California, has studied wastewater monitoring and created technology for this purpose. According to him, a single sample can provide a view of an entire city.

Levy stated that nearly all types of viruses we have searched for are able to be identified.

The monitoring system in the United States is expanding, but it is still fragmented. At present, the CDC receives wastewater data from 863 out of 3,143 counties, which accounts for approximately one quarter of the nation. These counties are typically more populous and encompass the majority of the U.S. population, but it does not include many rural homes that do not have access to municipal sewage systems.

In 2020, this method of monitoring diseases gained attention as health authorities started analyzing sewage for genetic signs of the coronavirus. It has now become a key component of the CDC’s tracking of COVID-19 due to a decrease in reported results from nasal swab tests.

In 2022, the CDC collaborated with a limited number of cities to search for polio in sewage systems. During this time, the CDC also initiated a new project to detect mpox (formerly known as monkeypox), which had caused outbreaks in the United States and other nations.

The latest research conducted by the CDC involved analyzing samples of wastewater from 89 locations in 16 different states between August 2022 and May 2023. When mpox DNA was found, the scientists cross-checked with reported cases from physicians to confirm their findings. Carly Adams, the lead author of the report, stated that this was done to ensure consistency.

According to CDC officials, the method not only proved effective, but also seems to be better at detecting mpox compared to COVID-19. However, they cautioned that making direct comparisons is challenging due to variations in pathogens and the accuracy of disease diagnosis and reporting by doctors.

The Centers for Disease Control and Prevention (CDC) has started gathering information on the flu and RSV. Approximately 40 states have been conducting tests for these viruses and submitting their findings. However, the CDC has not made this data available to the public yet as they are still determining the most effective way to present it. According to Kirby, it is expected to be published by next autumn.

The organization intends to begin monitoring bacteria that are immune to antibiotics. According to Kirby, the agency will also start keeping track of certain types of foodborne illnesses by the beginning of next year.

Kirby stated that the use of wastewater surveillance has exceeded all expectations. He expressed enthusiasm for exploring further applications of this new tool in gaining insight into diseases within communities.
