Yes. It usually stands for either standard or sexually transmitted disease. It really depends on the context in which it was used.
STD
std.
It stands for Sexual Disease. Normally, you will see STD which stands for Sexually Transmitted Disease.
STD is an acronym for Sexually Transmitted Disease, which means any disease which is commonly passed from person to person by sexual activity. Sometimes these diseases can also be passed along by other methods, such as HIV.
The acronym ftd stands Facebook transmitted diseases, which means that one could see the postings that friends of friends are posting on their news feeds. It is spreading like a STI, formerly known as STD, and thus, its name.

The following example demonstrates all 4 loop structures in C++. #include<iostream> int main() { int i; std::cout<<"For loop...\n"<<std::endl; for(i=0; i<10; ++i) std::cout<<i; std::cout<<'\n'<<std::endl; std::cout<<"While loop...\n"<<std::endl; i=0; while(i<10) std::cout<<i++; std::cout<<'\n'<<std::endl; std::cout<<"Do-while loop...\n"<<std::endl; i=0; do { std::cout<<i; }while( ++i<10 ); std::cout<<'\n'<<std::endl; std::cout<<"Goto loop...\n"<<std::endl; i=0; again: std::cout<<i; if(++i<10) goto again; std::cout<<'\n'<<std::endl; } Output: For loop... 0123456789 While loop... 0123456789 Do-while loop... 0123456789 Goto loop... 0123456789
Mumps is not a STD.
Haemophilus is not a STD.
