What is pneumococcus?

Pneumococcus, also known as Streptococcus pneumoniae, is commonly found in the human upper respiratory tract. Children under the age of 5 and elderly over the age of 65 are at high risk. While sinusitis and otitis media are the common mild diseases after being infected, some people's conditions may deteriorate rapidly and suffer from more serious conditions such as bacteremic pneumonia, sepsis, and meningitis. As the drug resistance of pneumococcus is increasing, it is very important to be vigilant in preventing pneumococcal infections.

What are the symptoms of pneumococcal infections?

In general, the symptoms of pneumococcal infections are similar to those caused by influenza viruses, which include upper respiratory tract symptoms such as fever and cough. However, specific symptoms depend largely on the site of infection.

  • Otitis media: fever and earache, possibly with discharge
  • Pneumonia: fever, shortness of breath, chills, and productive cough
  • Meningitis: fever, neck stiffness and delirium
  • Bacteraemia and septicaemia: joint pain and chills. Other parts of the body may also be infected at the same time, which may result in pneumonia, meningitis, etc.

How do people get infected by pneumococcus?

Pneumococcus can survive in organs along the human upper respiratory tract, such as the nose and throat. In fact, even healthy people can sometimes be carriers without showing any symptoms. Pneumococcus can spread through droplets while coughing and sneezing or through indirectly touching respiratory secretions. Children under the age of 5 and elderly over the age of 65 are at high risk in view of their weaker immunity and higher susceptibility to pneumococcal invasion.

Other high-risk individuals who are more susceptible to pneumococcal infections include people who have suffered from invasive pneumococcal infections in the past, people with low immunity (such as cancer patients, people infected with HIV, or those who have undergone splenectomy), patients with chronic diseases (such as diabetes or cardiovascular diseases), and people with cochlear implants.

How to effectively prevent pneumococcal infections?

To prevent pneumococcal infections, a safer and more effective method nowadays is be vaccinated with pneumococcal vaccines. Currently, 13-valent (for 13 serotypes) and 23-valent (for 23 serotypes) vaccines are more commonly available in the market. While 13-valent vaccines are suitable for people aged 6 months to 17 years and over 50 years old, 23-valent vaccines are suitable for high-risk individuals aged 2 or above. Although people can be vaccinated with 23-valent pneumococcal vaccine and influenza vaccine at the same time, the vaccinations need to be given in different parts of the body.

In addition to being vaccinated with preventive vaccines, it is necessary to build up good body immunity. In particular, it is important to always maintain a balanced diet, engage in moderate exercise, and have adequate rest. Make sure to pay attention to personal hygiene and keep the environment clean. Remember to cover your nose and mouth when sneezing or coughing and wash your hands frequently.
