World TB Day
24 March 2021

Prevention of TB is important, please support!

The origin of World TB Day
Each year, Stop TB advocates around the world mark the date 24 March as “World TB Day” when the German bacteriologist Robert Koch announced that he had discovered the cause of tuberculosis, the TB bacillus in 1882. There has been more than 100 years since Koch's discovery but TB is still a major health problem around the globe, especially in the developing world. World TB Day is a valuable opportunity to raise public awareness and knowledge about tuberculosis so that it can be prevented and controlled effectively and proactively. 
TB in Hong Kong
In recent years, there are still around 4,000 to 5,000 reported cases of TB each year. In 2020 (provisional figure), the total number of TB notifications was 3,699. For every 100,000 people, 49.3 developed TB disease. The notification figure showed dramatic improvement when compared with 1950s and 1960s but was still high when compared with the figures of the European and American countries.
Common misunderstandings about TB 
Nowadays, people still have some misunderstandings about TB. Some examples of misunderstandings: all TB patients should be admitted to hospital for isolation; after taking anti-TB treatment for a few weeks, the drugs can be stopped if the symptoms have disappeared.
