Health certificate is a health certificate that everyone must apply for when going abroad, which proves that you have no infectious diseases or diseases endangering public safety before traveling abroad.
This physical examination is valid for one year. There is a place called Entry-Exit Inspection and Quarantine Bureau in provincial capital cities and large non-provincial capital cities directly under the Central Government. It has a physical examination center called International Travel Health Center. You must have a physical examination here.
Physical examination depends on your position on the ship and the requirements of the shipowner, but some items must be done, such as vision and height, chest X-ray, electrocardiogram, B-ultrasound, liver function and urine test. Some companies require HIV reports, as well as alcohol and drug test reports. If your vaccine is out of date or it is the first time to do it, you need yellow fever and cholera vaccines. Yellow fever 10 years, injection. Cholera is a capsule oral medicine. The specific fee is charged according to the project you do, so there is no uniform price. If all the above are done at the same time, it will be around 700. However, it is recommended to bring more.
The so-called yellow skin is a small certificate of yellow color. Because it is yellow, it is called yellow skin. This yellow skin is your vaccination record book, just like yellow fever and cholera on it. If you are vaccinated with these two vaccines, it will be recorded in your yellow skin.
By the way, I'll add the address If there is already a company, it is recommended to do it nearby or at the place specified by the company. If one item needs to be rechecked, you can recheck it before boarding the ship.
Good luck.
