Classifying Indoor Air Problems: What Can Go Wrong?

Table 3-1 summarizes health symptoms and associated SBS and BRI illnesses. The table is particularly useful in identifying which illness is the only one to exhibit a certain symptom, or only illness that does not exhibit that symptom. This helps with the sorting process. For example, eye irritation is only identified with SBS; not BRIs. Humidifier fever is the only illness to exhibit lethargy but not general malaise. Malaise is a vague feeling of uneasiness or physical discomfort. Lethargy is characterized by abnormal drowsiness or torpor, apathy, sluggishness and great lack of energy. When a building associated illness is suspected, then, abnormal drowsiness without any feelings of physical uneasiness would suggest humidifier fever. If these symptoms are accompanied by the “Monday Morning Phenomena,” the possibility of humidifier fever is even greater.
Effects of infrasound on health: looking for improvements in housing conditions

Persinger [37] stated that infrasound has a special capacity to affect human health because its frequency and amplitude cover those generated by the human body. The muscles and the body generally vibrate at frequencies between 5 and 40 Hz. There are moderate correlations between infrasound and nausea, malaise, fatigue, area aversion, non-specific pain and sleep disturbance when SPLs exceed about 50 dB SPL for protracted periods. This indicates the particular importance of individual variability in infrasound exposure. Short-term exposure to very high sound pressure fluctuations can lead to significant sensitivity in subpopulations, and this relates to experiments carried out by Cole et al.[62] involving intense infrasonic space flight simulations for 2 min, where reports concluded that participants experienced tingling sensations of the tympanic membrane, nausea, middle ear pain, salivation, transient headache or testicular pain [37].

Characterized by fever, malaise and generalized pruritic vesicular rash, varicella (also known as chickenpox) is an acute infectious disease triggered by primary infection of the varicella-zoster virus (VZV) (Breuer and Whitley 2007; Prymula et al. 2014). It is transmitted by aerosolized droplet spread and skin contact and is highly transmissible with an attack rate of up to 90% after close contact of patients (Lee et al. 2004). The incubation period of varicella is about 10–21 days (World Health Organization 2014). As the annual incidence increases these years (from 3.17/100,000 in 2005 to 33.86/100,000 in 2015) (Sui et al. 2019), varicella is still China’s critical public health issue.
A comprehensive summary of disease variants implicated in metal allergy
Published in Journal of Toxicology and Environmental Health, Part B, 2022
Panniculitis is another type of ASIA that has been correlated with metal allergy. This condition is characterized by the development of lesions within the host’s adipose tissue – most frequently presenting as erythematous nodules within the subcutaneous fat layer (Wick 2017). A number of different immune cell subsets may be detected within these lesions, including lymphocytes, neutrophils, eosinophils, and macrophages, and their development is often accompanied by general symptoms of malaise including fever and fatigue (Requena and Yus 2001). Although panniculitis might develop following exposure to many different types of antigens, allergenic metals were cited as causative agents of the disorder in many instances. As described in one report, implantation of a metal-based orthopedic device was responsible for the development of panniculitis in one subject. Following surgery, the patient’s incision site failed to heal (no microbial infection), lesions of the adipose tissue were detected at the site of implantation, and general symptoms of ASIA were present (myalgia, low-grade fever, and arthralgia) (Radenska-Lopovok et al. 2021). Although it was concluded that the metal-containing implant was responsible for ASIA/panniculitis development, specific metals responsible for the condition were not identified. In another report, an accidental molten aluminum burn was identified as the cause of panniculitis that subsequently developed in an exposed worker (Chao, Lee, and Lee 2010). Directly following the accident, the individual developed localized panniculitis and eosinophilic cellulitis that resolved following a month of systemic corticosteroid therapy. Several months later, the patient had a relapse and reemergence of symptoms. It was determined that the subject had become sensitized to Al following the initial accident, and subsequent exposures to the metal caused similar outbreaks.
