Sexually transmitted diseases (STDs) are transmitted through sexual contact, including vaginal, anal, and oral sex. They can be passed from one person to another through the exchange of bodily fluids such as blood, semen, vaginal secretions, and breast milk. STDs can also be transmitted through skin-to-skin contact with infected areas, such as genital warts or herpes sores. It is important to practice safe sex and get tested regularly to prevent the spread of STDs. **

Digital radio can be wirelessly transmitted to a motorcycle helmet through the use of Bluetooth technology. A Bluetooth transmitter can be connected to the motorcycle's audio system, which then sends the audio signal wirelessly to a Bluetooth receiver installed in the helmet. The receiver in the helmet can then play the digital radio signal through built-in speakers or headphones. This allows the rider to listen to their favorite radio stations without the need for any physical connections. **

Scabies is transmitted through close, prolonged skin-to-skin contact with an infected person. The mites that cause scabies burrow into the skin and lay eggs, leading to the spread of the infestation. It can also be transmitted through sharing clothing, bedding, or towels with an infected person. Scabies is highly contagious and can easily spread in crowded living conditions or among family members. **

Diseases that are transmitted from person to person include the common cold, influenza, tuberculosis, HIV/AIDS, hepatitis, and COVID-19. These diseases can be spread through various means such as respiratory droplets, bodily fluids, and close contact with an infected person. It is important to practice good hygiene, get vaccinated, and take necessary precautions to prevent the spread of these diseases. **

Herpes is primarily transmitted through direct skin-to-skin contact with an infected person, particularly during sexual activity. The virus can be spread through contact with the herpes sores, but it can also be transmitted even when there are no visible symptoms. Herpes can also be spread through oral-genital contact, and in some cases, it can be transmitted from a mother to her baby during childbirth. It's important to practice safe sex and communicate openly with sexual partners to reduce the risk of transmitting or contracting herpes. **

No, cats do not transmit scabies to humans. Scabies is caused by the human itch mite, Sarcoptes scabiei, and is specific to humans. Cats can get a different type of mite infestation called "mange," but this is caused by a different species of mite and cannot be transmitted to humans. It's important to seek veterinary care if you suspect your cat has mange or any other skin condition. **

Digital radio can be wirelessly transmitted to a helmet on a motorcycle through the use of Bluetooth technology. A Bluetooth transmitter can be connected to the motorcycle's audio system, which then sends the digital radio signal wirelessly to a Bluetooth receiver installed in the helmet. The receiver in the helmet can then pick up the signal and play the radio station through the helmet's speakers or through a connected headset. This allows the rider to listen to their favorite radio stations without the need for any physical wires or connections. **

Hepatitis C is primarily transmitted through contact with infected blood. This can happen through sharing needles or other equipment used to inject drugs, receiving contaminated blood transfusions or organ transplants, or through needlestick injuries in healthcare settings. It can also be transmitted through sharing personal items such as razors or toothbrushes that may have come into contact with infected blood. Less commonly, Hepatitis C can be transmitted through sexual contact or from an infected mother to her baby during childbirth. **
