KOTA KINABALU: Two cases of pertussis (whooping cough) have been detected in interior Keningau district and medical authorities have been put on alert to contain the spread of the highly contagious infection.
An image of an official memo from the Keningau Health Department highlighting two confirmed cases in Taman Kota in Kg Sungai Keningau, about 180km from here, has gone viral on social media.
The whooping cough episodes were detected on Aug 2.
Sabah Health department director Datuk Dr Christina Rundi has declined to confirm or deny the official memo dated Aug 2 signed by Keningau Health Officer Dr Abdul Mardusi Manah.
According to the United States' Centre for Disease Control, whooping cough is a highly contagious disease caused by the bacterium Bordetella pertussis.
The air-borne disease, which causes severe, almost uncontrollable coughing, affects people of all ages.
It can be very dangerous for babies and young children, as it can cause pneumonia, seizures, brain damage, and even death.
The best protection against pertussis is by getting vaccinated, said the CDC report.
