Terrifying Symptoms of Deadly ‘Crying Disease’ Explained

A deadly mystery illness has swept through parts of the Democratic Republic of Congo, leaving doctors scrambling for answers. The outbreak has already claimed more than 50 lives, with 413 reported infections—and most victims succumbing within just 48 hours of symptoms appearing.

The first known cases were reported on January 21 in the town of Boloko, where three young children fell ill after eating a dead bat. Soon after, more cases emerged, sparking fears of a rapidly spreading epidemic.

Officials say patients are suffering from severe fever, vomiting, and internal bleeding, resembling hemorrhagic fever illnesses like Ebola and Marburg—yet tests for these deadly viruses have come back negative. Other reported symptoms include:

• Neck and joint pain
• Excessive sweating and shortness of breath
• Severe thirst (in adults) and persistent crying (in children)
• Diarrhea and fatigue in early cases

Doctors describe the outbreak as “really alarming,” while officials warn that the mystery disease could have global implications.

Despite its hemorrhagic-like symptoms, no known virus has been identified. The World Health Organization (WHO) is investigating whether a toxic agent—rather than a virus or bacteria—could be responsible.

Adding to the complexity, about half of the infected patients have tested positive for malaria, similar to a separate outbreak in Congo last year. Many patients are also suffering from malnutrition, which could be worsening the effects of the illness.

Dr. Zania Stamataki, an immunologist at the University of Birmingham, warns:
“The 48-hour fatality window is extremely alarming.”

The transmission method remains unclear. Typically, hemorrhagic diseases spread through bodily fluids, not through the air—raising more questions about how this outbreak is expanding so quickly.

So far, cases have been reported in two remote villages in Congo’s Équateur province, with numbers climbing fast. Some reports suggest nearly 1,000 people may be infected.

The WHO is calling for urgent action, warning that weak healthcare infrastructure and the region’s remote location make containment challenging.

Dr. Michael Head, a global health expert, cautions:
“There is huge uncertainty. Hundreds of cases, over 50 deaths, and hemorrhagic symptoms—this is serious.”
