1. Vaccination:- Pertussis vaccines are the most effective way to prevent the spread of the disease. Ensure that you and your family members are up-to-date with the recommended pertussis vaccinations.- The childhood pertussis vaccine (DTaP) is typically given in a series of 5 doses, starting at 2 months of age.- The adolescent and adult pertussis vaccine (Tdap) is recommended for everyone, including pregnant women, to provide protection and prevent transmission to infants.2. Isolation and treatment:- If someone in your household is diagnosed with pertussis, they should be isolated from others, especially infants and young children, until they have completed the appropriate antibiotic treatment.- Individuals with pertussis should cover their coughs and sneezes and avoid close contact with others to prevent the spread of the disease.3. Practicing good hygiene:- Wash your hands frequently with soap and water, especially before handling food or caring for infants.- Avoid touching your face, especially your eyes, nose, and mouth, to prevent the spread of the bacteria.4. Informing close contacts:- If you or a family member is diagnosed with pertussis, inform your close contacts, such as family members, friends, and coworkers, so they can seek medical attention and get tested or treated if necessary.5. Maintaining a clean environment:- Regularly clean and disinfect surfaces, especially in areas where someone with pertussis has been, to remove any lingering bacteria.
