Yes. 1-2 days before you feel symptoms you could be shedding virus particles that infect others. The precautions for prevention of the spread of Infectious Diseases must be followed at all times and in all seasons. This includes proper frequent hand washing, avoiding touching your eyes, mouth or nose, remembering to get your flu vaccination each year, staying at least 6 feet away from someone ill, coughing and sneezing into a tissue that is immediately thrown away, staying home when you are sick, and other ways to protect yourself and others. A more complete list of ways to protect yourself is in the related questions section for this question.
More details on how long you are infectious:
Adults shed influenza virus from the day before symptoms begin through 5-10 days after illness onset. However, the amount of virus shed, and presumably infectivity, decreases rapidly by 3-5 days after onset in an experimental human infection model. Young children also might shed virus several days before illness onset, and children can be infectious for 10 or more days after onset of symptoms. Severely immunocompromised persons can shed virus for weeks or months.

Most individuals with swine flu are contagious from about one day before symptoms appear until about five to seven days after becoming sick. However, some people, particularly those with weakened immune systems, may remain contagious for a longer period. It's always best to consult a healthcare provider for personalized advice.
Can you pass the flu before you even know that you have it?
Yes, the flu virus, like many viruses can be in your cells and infecting you making you contagious, before you have symptoms to know you even have a viral infection/the flu. It is usually for 1-3 days before you have symptoms that you might already be infected. See the related question below for more information about the incubation of flu viruses.
If you are around a person who is not exhibiting flu symptoms but comes down with swine flu 3-4 days later are you exposed to swine flu?
A person can be contagious with a virus like the flu for a day or two before they even notice their own symptoms. So if you are around them during that time frame and in close or direct contact with them, the potential exists for you to come down with the flu.

Are you contagious if you are not running a fever?
At the beginning of a viral infection, like the cold and flu, you can be contagious while showing no symptoms at all for a day or even two. However, the rule of thumb is that after having a fever with the flu and then it subsides, once you have gone a full 24 hours after that without a fever (when taking no fever-reducing medicines), you are considered no longer contagious and can go back into public again.
How long after taking Tamaflu is a person contageous?
A person infected with the flu virus can be contagious starting about one day before symptoms appear and typically remains contagious for about five to seven days after becoming sick. Taking Tamiflu (oseltamivir) can help reduce the duration of flu symptoms and potentially lower the contagious period, but individuals should still consider themselves contagious for the same time frame. It's important to practice good hygiene, such as handwashing and covering coughs, to prevent spreading the virus to others during this time.

Is a person contagious after Swine Flu treatment?
You would not be contagious DUE TO the swine flu treatment, but you may still be contagious after having treatment, depending on when you were exposed to the virus or when you contracted the swine flu, what the treatment was, and how long it has lasted to date. Usually treatment does not cure the flu, only lessens the symptoms while your body is killing the invading virus. It typically takes your body 7 to 10 days to fight off the flu once infected. If you have the flu, you would be considered no longer contagious after you have gone a full 24 hours without a fever (while taking no fever-reducing medicines). If by "treatment" you include preventive flu vaccinations, then you would not be contagious from having had the vaccine, since it is made with virus particles that can not make you sick. There is a very rare risk that someone who received the live virus vaccine in the nasal spray vaccination could give the flu to another person, immediately after receiving the nasal spray, if the other person has a malfunctioning immune system, such as with AIDS, but it is unlikely.
