In Hong Kong, seasonal influenza is usually more common in periods from January to March/April and from July to August. Influenza viruses mainly spread through droplets when infected people cough, sneeze or talk. To prevent seasonal influenza, members of the public should maintain good personal and environmental hygiene. As persons who contract influenza and COVID-19 at the same time are at a higher risk of severe complications and death, priority groups are strongly recommended to receive seasonal influenza vaccine and additional COVID-19 booster at the same time as soon as possible to reduce the risk of serious illness and death. Please consult family doctors about the details of receiving seasonal influenza vaccination. | |

Since May 2022, there has been a multi-country outbreak of monkeypox reported from many countries in widely disparate geographical areas globally. Infection could occur when a person comes into contact with the virus from infected animals, infected humans or contaminated materials.
Members of the public should take precautions and avoid close physical contact with persons or animals suspected of contracting Mpox. They should seek medical attention as soon as possible if they experience symptoms of Mpox, including rash, fever, intense headache, sore throat, myalgia and lymphadenopathy.

Hand, foot and mouth disease (HFMD) is a common disease in children caused by enteroviruses such as coxsackieviruses and enterovirus 71 (EV71). HFMD caused by EV71 is of particular concern as it is more likely associated with severe complications (such as viral meningitis, encephalitis and poliomyelitis-like paralysis) and even death. In Hong Kong, the usual peak season for HFMD in Hong Kong is from May to July and another peak may also occur from October to December.
The disease is most contagious during the first week of the illness and the viruses can be found in stool for weeks. It mainly spreads by contact with an infected person’s nose or throat discharges, saliva, fluid from vesicles or stool, or after touching contaminated objects.

Other symptoms include headache, fever, and abdominal cramps. In general, the symptoms begin 1 – 2 days following infection with a virus that causes gastroenteritis. Depending on the type of viruses causing the illness, however, the symptoms may last for 1 – 10 days. As a general measure to prevent gastroenteritis, members of the public are advised to maintain good personal hygiene, food hygiene and environmental hygiene.

It is considered one of the greatest threats to global health and economy.
Antibiotics, a type of antimicrobial, are medications used for treating bacterial infection. When antibiotics wipe out disease-causing bacteria in our body, normal bacteria are also killed, thereby increasing the opportunity for resistant bacteria to grow and multiply. These resistant bacteria are sometimes referred to as ‘superbugs’. Some superbugs are capable of resisting more than one antibiotic causing infections difficult to treat. Although there may be non-first-line antibiotics available, they may be less effective or cause more side effects. Moreover, AMR develops at a fast rate than the development of new medicines. If the problem of AMR does not improve, there would be fewer effective treatment options. To combat antimicrobial resistance, members of the public should follow your doctor’s advice when taking antibiotics; do not demand antibiotics from your doctor; do not stop taking antibiotics by yourselves even if you are feeling better; practise frequent hand hygiene, especially before eating and taking medicine, and after going to the toilet; ensure your vaccination is up-to-date; and maintain cough etiquette, wear a surgical mask if you have respiratory symptoms. |

In recent years, more people enjoy running (or even the long-distance running). Running is an aerobic exercise. It is not only good for health but also helps weight control, which will in turn reduce the risks of developing many chronic diseases (e.g. hypertension, diabetes mellitus, and cardiovascular diseases) due to overweight. However, to achieve optimal health, we should run in a proper way. Below is some healthy advice about running. | |
