con benh » can benh, doan benh, song benh
tai cac » tai cuc
cac che » cac he, cac chien, cac chat
co benh » so benh, o benh, bo benh
te cong » tai cong, thi cong
kho y » khoa y, nho y
dong » dung

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: truyen tai cac che đe ((co benh) OR (con benh)) kho y ((te cong) or (thu cong)) dong~.
• If you are trying to use Boolean operators, they must be ALL CAPS: truyen tai cac che đe ((co benh) OR (con benh)) kho y ((te cong) OR (thu cong)) dong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "truyen tai cac che đe ((co benh) OR (con benh)) kho y ((te cong) or (thu cong)) dong".
• Adding a wildcard symbol may retrieve word variants: truyen tai cac che đe ((co benh) OR (con benh)) kho y ((te cong) or (thu cong)) dong*.
