CHP investigates case of invasive Haemophilus influenzae type b infection
*************************************************************************
The case involves a 43-year-old female with underlying illnesses. She presented with fever, cough and shortness of breath since August 22. She attended the Accident and Emergency Department of Kwong Wah Hospital the next day (August 23) and was admitted for treatment. The patient is now in critical condition. Her blood and sputum samples tested positive for Hib upon laboratory testing. Her clinical diagnoses were pneumonia and sepsis.
The patient had no recent travel history. Initial enquiries revealed that two close contacts developed mild respiratory symptoms and were advised to seek medical consultation promptly. Investigations are ongoing.
"Invasive Hib infection has been a statutorily notifiable infectious disease since July 2008. Invasive Hib infection commonly presents clinically as an infection of membranes covering the brain (meningitis), often accompanied by bacteria entering the bloodstream. It may also affect other parts of the body such as the lungs, the epiglottis (upper part of the throat), joints and bones. Prompt antibiotic treatment is necessary," the Controller of the CHP, Dr Edwin Tsui, said.
"Hib infection can be spread by contact with the nose or throat secretions of a patient. If a persistent fever, unusual changes in behaviour or other deteriorating conditions develop, or if in doubt, seek medical attention immediately," Dr Tsui added.
Members of the public are advised to observe personal hygiene and take heed of the preventive measures below:
- Maintain hand hygiene and clean hands properly;
- Wash hands when they are soiled with respiratory secretions, such as after sneezing or coughing;
- Cover the nose and mouth while sneezing or coughing and dispose of nasal discharge and sputum properly;
- Do not share eating and drinking utensils, and wash them thoroughly after use;
- Avoid going to crowded places if not feeling well; and
- An effective vaccine against Hib is available. For personal protection, seek advice from a healthcare professional.
