Unidentified Illness in Congo Linked to Severe Respiratory Ailments, Reveals WHO
It's suspected that the illness afflicting individuals in the Democratic Republic of the Congo is predominantly triggered by a respiratory virus, with malaria and malnutrition likely amplifying its effects, as suggested in a report published by the WHO on a Friday. This assessment diverges from previous reports that linked the ailment, once known as "disease X," to severe malaria. However, this new report aligns with the hypothesis proposed by the Africa CDC, suggesting that the condition might stem from a viral infection against the backdrop of malaria and malnutrition.
Through lab tests, 72% of the 89 sampled patient specimens tested positive for widespread respiratory viruses. The most prevalent findings were associated with influenza A, rhinoviruses, or the SARS-CoV-2 virus, the virus responsible for Covid-19. Over 60% of the analyzed samples revealed a presence of malaria, a condition commonly associated with Plasmodium falciparum, which is particularly prevalent in the DRC, accounting for approximately 12% of all global cases and fatalities.
The WHO report also provides an update on the current disease situation, revealing 891 reported cases and 48 related deaths. Children continue to bear the brunt of the disease burden, with nearly half of all cases and fatalities occurring in children under 5 years old. In adult cases, women have accounted for 66% of the recorded occurrences, with WHO officials speculating that gender disparities might arise from distinctive household transmission dynamics, potentially due to mothers' increased caretaking role for sick children. The disease has been confined to the Kwango Province.
The disease's intensity in children seems to be exacerbated by malnutrition, with the WHO report noting, "the affected area has witnessed a decline in food security in recent months, accompanied by escalating levels of acute malnutrition." The report further mentions that approximately 4.5 million children under 5 in the DRC are expected to confront acute malnutrition, along with more than 3.5 million pregnant or lactating women who might experience severe malnutrition. This food instability will only exacerbate negative outcomes for various infectious diseases.
Ultimately, the report concludes that local community risk is substantial, while national, regional, and global risks remain relatively low.
While the report presents compelling evidence linking the mystery illness to common respiratory viruses, further analysis is necessary. Only a limited number of patient samples have undergone examination. Continued surveillance in the region, along with increased testing, is essential. Additionally, the report emphasizes various factors that can influence infectious disease severity; the current data suggests that this condition is not caused by a novel pathogen but rather highlights the enhanced impact of known pathogens on vulnerable populations.
The mystery disease in the Congo could potentially be linked to commonly found respiratory viruses such as influenza A or rhinoviruses, as 72% of sampled patient specimens tested positive for these viruses. Who is yet to determine if 'Disease X', once linked to severe malaria, is a contributing factor in this case, given the new report's alignment with the Africa CDC's hypothesis of a viral infection in the context of malaria and malnutrition.
