Strong infrastructure and antibiotics are available, but early detection remains crucial.

A suspected plague-related death has reignited global concern about pneumonic plague, the most severe form of the infection caused by Yersinia pestis. While the incident has prompted questions about India’s preparedness, infectious disease specialist Dr Ishwar Gilada has reassured the public that there is no immediate cause for alarm. He emphasized that the reported case involved accidental laboratory exposure rather than community transmission, underscoring the need for a measured response.

Plague, though rare, can manifest in three forms: bubonic, septicemic, and pneumonic. Bubonic plague, the most common, is characterized by painful swelling of lymph nodes and is typically linked to fleas and rodents. Septicemic plague spreads through the bloodstream, potentially leading to organ failure. Pneumonic plague, the most dangerous, directly affects the lungs and can be fatal if treatment is delayed. Dr Gilada cautioned against assuming every severe pneumonia case is plague, noting that bubonic plague does not spread person-to-person.

India’s experience with the 1994 Surat outbreak demonstrated both the health and socio-economic consequences of plague. That episode disrupted travel, trade, and tourism, highlighting the need for clear communication and swift containment measures. According to Dr Gilada, India has since strengthened its hospital and laboratory networks, particularly during the Covid-19 pandemic, when testing capacity expanded rapidly nationwide. This infrastructure can now support plague detection, with PCR, antigen, and antibody testing providing diagnostic support.

The expert stressed that early diagnosis and immediate treatment are critical in managing pneumonic plague, which can escalate quickly. Fortunately, India has access to a range of effective antibiotics including tetracyclines, doxycycline, ciprofloxacin, levofloxacin, gentamicin, and co-trimoxazole- that are both inexpensive and widely available. When administered promptly, these medicines can cure the infection.

Dr Gilada concluded that India is well-positioned to respond to potential plague cases, thanks to its expanded laboratory capacity, isolation facilities, and accessible treatments. However, he warned against complacency, emphasizing that vigilance, preparedness, and rapid intervention remain essential. For the public, his message was clear: stay alert, but do not panic.
