In addition, episodes starting after childbirth may be triggered by adrenal corticosteroids, surgical operations (such as Caesarean section) or bromocriptine as an alternative to, or in addition to, the postpartum trigger. Course of the illness
With modern treatment, a full recovery can be expected within 6–10 weeks. After recovery from the psychosis, some mothers have depression, which can last for weeks or months. About one third have a relapse, with a return of psychotic symptoms a few weeks after recovery; these relapses are not due to a failure to comply with medication, because they were often described  before pharmaceutical treatment was discovered. A minority have a series of periodic relapses related to the menstrual cycle. Complete recovery, with a resumption of normal life and a normal mother-infant relationship is the rule.Many of these mothers experience other bipolar episodes, on the average about one every six years. Although suicide is almost unknown in an acute puerperal manic or cycloid episode, depressive episodes later in life carry an increased risk, and it is wise for mothers to maintain contact with psychiatric services in the long term. In the event of a further pregnancy, the recurrence rate is high – in the largest series, about three quarters had a recurrence, but not always in the early puerperium; the recurrence could occur during pregnancy, or later in the postpartum period. This suggests a link between early onset and other onset groups.
When dealing with L. pneumophila serogroup 1, the urine antigen test is useful for early detection of Legionnaires disease and initiation of treatment, and has been helpful in early detection of outbreaks. However, it does not identify the specific subtypes, so it cannot be used to match the person with the environmental source of infection. The Legionella bacteria can be cultured from sputum or other respiratory samples. Legionella spp. stain poorly with Gram stain, stain positive with silver, and are cultured on charcoal yeast extract with iron and cysteine (CYE agar). A significant under-reporting problem occurs with legionellosis. Even in countries with effective health services and readily available diagnostic testing, about 90% of cases of Legionnaires disease are missed. This is partly due to the disease being a relatively rare form of pneumonia, which many clinicians may not have encountered before, thus may misdiagnose. A further issue is that people with legionellosis can present with a wide range of symptoms, some of which (such as diarrhea) may distract clinicians from making a correct diagnosis. Prevention
Although the risk of Legionnaires disease being spread by large-scale water systems cannot be eliminated, it can be greatly reduced by writing and enforcing a highly detailed, systematic water safety plan appropriate for the specific  facility involved (office building, hospital, hotel, spa, cruise ship, etc.) Some of the elements that such a plan may include are:

Keep water temperature either above or below the 20–50 °C (68–122 °F) range in which the Legionella bacterium thrives.
