Causes. Pertussis, a respiratory illness commonly known as whooping cough, is a very contagious disease caused by a type of bacteria called Bordetella pertussis.hile pertussis vaccines are the most effective tool we have to prevent this disease, no vaccine is 100% effective.

1 Do-it-yourself pool cleaning runs $20-$100 per month for chemicals during the summer after initial purchase of pool tools including a vacuum head and hose from $50, and a maintenance kit with a wall brush, leaf skimmer, test kits and telescopic pole for around $60. Regular filter cleaning costs around $60-$65. 2  Power vacuuming is intense cleaning for a neglected pool and runs $55-$124 per hour. 3  Pools that are properly covered during the winter will require an opening service that prepares the pool for summer use.
My estimate of the on-going cost of a Phoenix area pool would be $35 for the pool pump, $25/month for chemicals and $60/month for major expenses, so plan to budget roughly $120/month for the maintenance of your swimming pool.ool chemical cost can vary depending on the system used to keep the chemicals in balance. Newer technology uses salt water systems to assist in chlorinating the pool. A rough estimate for chlorine, acid and misc. chemicals such as diatomacheous earth for the filter would be approximately $300/year or $25/month.
