Covid in 2012. 6 patients.
Patient 1 (63 years old): Admitted April 26, 2012 after 14 days in the mine. Developed fever, dry cough progressing to bloody sputum, dyspnea, aching limbs, and headache. Rapid progression to severe interstitial pneumonia with ground-glass opacities. Died after 12 days in hospital on May 7, 2012 from respiratory failure.
Patient 2 (42 years old): Admitted April 25, 2012 after 14 days exposure. Similar symptoms: high fever, cough with sputum, severe breathing difficulty. Progressed to ARDS requiring mechanical ventilation, lymphocytopenia, elevated D-dimer, and pulmonary thromboembolism. Died after 48 days on June 12, 2012.
Patient 3 (45 years old): Admitted April 27, 2012 after 14 days in the mine. Severe symptoms including persistent high fever, productive cough, profound dyspnea. Longest hospitalization among the deceased at 109 days. Developed ARDS, immune cell depletion, and complications leading to death on August 13, 2012.
Patient 4 (46 years old): Admitted April 26, 2012 after 14 days exposure. Severe course with fever, cough, dyspnea, ARDS requiring mechanical ventilation, clotting issues, and low oxygenation. Underwent thymectomy on June 27, 2012. Survived after 137 total days, discharged improved on September 10, 2012.
Patient 5 (30 years old): Admitted May 2, 2012 after only 5 days in the mine. Milder symptoms of fever, cough, and fatigue. Shorter course with lymphocytopenia but no ventilation needed. Discharged alive after 26 days on May 28, 2012.
Patient 6 (32 years old): Admitted April 26, 2012 after 4 days exposure. Similar mild symptoms to patient 5. Recovered steadily and discharged after 32 days on May 28, 2012.
Summary: All patients shared initial symptoms of fever, cough, dyspnea, myalgia, and headache after cleaning bat guano.
Older patients with longer exposure (patients 1-4) developed severe bilateral interstitial pneumonia, ground-glass opacities, ARDS, lymphopenia, and secondary infections. The three oldest died from respiratory failure or related complications. The two youngest had shorter, milder illnesses and recovered quickly. Patient 4’s survival despite severity is notable due to extended supportive care including ventilation, antithrombotics, and thymectomy.
