US health authorities have announced that soil and water samples taken from Mississippi contain bacteria that cause a rare but serious disease called melioidosis. The authorities have thus alerted the doctors of the country, asking them to be vigilant in the face of possible symptoms of this disease in patients.
Two individuals living in the southern United States, in the Gulf of Mexico region, separately contracted the disease in 2020 and 2022, prompting the Centers for Disease Control and Prevention (CDC) to take these swabs in and near of their homes. Three samples, soil and puddles, tested positive for the bacterium (Burkholderia pseudomallei).
Despite everything, the CDC considers that the risk for the general population remains “very low”. They are currently investigating to determine how widespread the bacteria is in the environment. Symptoms of melioidosis can be broad, such as fever, joint pain, or headache. It can cause pneumonia, abscess formation, or infections.
Worldwide, melioidosis is fatal in 10-50% of cases. It is recommended for more fragile people living in Mississippi to avoid contact with muddy water, to protect their wounds, or to wear waterproof boots and gloves while gardening.
About twelve cases of melioidosis are diagnosed each year in the United States, mostly in people who have traveled to countries where this bacterium is endemic, especially in tropical regions. Other cases have also been caused by the contamination of products from these countries.
