@cody Regarding Hepa B, I think that it will only affect your application if your applying for a medical course. However, it still depends on what type of hepa B the person is infected with: acute or chronic type. If the person is infected with the chronic type,regardless of the course pursued, then this is a problem since it will pose as a health threat to their citizens. But with the acute type , the person might have a chance, although, he/she might need to pass the medical exam to prove that the disease is completely cured.
