On the morning of June 8, Dr. Nguyen Minh Tien, Deputy Director of the City Children's Hospital (HCMC), said that after 2 days of treatment, the child's condition improved, fever reduced, heart rate reduced to 136-140 beats/minute, hemodynamics stable, and continued to be actively monitored and treated.

Medical history showed that in the first 3 days the child had fever, nausea, vomiting, and a rash with blisters on the palms and soles of the feet. On the 3rd day, the child had a fever, was startled, had wide eyes and trembling limbs, so he was admitted to the local hospital. Here, the doctor diagnosed grade 3 hand, foot and mouth disease, and treated according to the treatment regimen. However, the condition did not improve, so he was transferred to the City Children's Hospital (HCMC).

After admission, the child showed signs of drowsiness, heart rate over 200 beats/minute, continuous high fever, diagnosed with grade 4 hand, foot and mouth disease. Tests showed high cardiac enzymes, slightly increased liver enzymes, severe metabolic acidosis,

The doctor performed endotracheal intubation to help with breathing, treated shock with vasopressor fluids, administered immunomodulators, sedatives, and actively reduced fever. However, the condition did not improve, so the team performed continuous blood filtration.
