Seasonality and long-term trends of pediculosis capitis and pubis in a young adult population

Epidemiology and morbidity of scabies and pediculosis capitis in resource-poor communities in Brazil

“…Outbreaks of head lice occur commonly after school holidays, 35 and previous studies have shown seasonal variation of pediculosis capitis in children, with a lower incidence during summer 5,34 . Other studies in adult populations reported a decrease of prevalence in winter and explained this by a higher temperature in summer which should favour egg laying and hatching closer to the outer surface of the hair, facilitating the spread of lice from person to person 36,37 …”

Seasonality trends of Pediculosis capitis and Phthirus pubis in a young adult population: follow‐up of 20 years

“…In a previous report by Gillis et al ., 3 based on a database of 11 years, it was shown that the seasonality of Pediculosis capitis includes a trend of higher rates during the warmer months of the year. They suggested that the higher temperature in summer may assist in egg laying and hatching closer to the outer surface of the hair, thus enabling the spread of eggs and viable lice.…”

“…In the Israel Defense Force (IDF), Phthirus pubis and Pediculosis capitis have been routinely reported and monitored by the epidemiology unit of the IDF for more than two decades. There are only a few reports that investigated the seasonality of these infestations with controversial results 3,4 …”

Secular trends in the epidemiology of pediculosis capitis and pubis among Israeli soldiers: a 27‐year follow‐up

“…In a previous report by Gillis et al, 6 based on a database of 11 years, it was suggested that the epidemiologic pattern of pediculosis capitis includes a wave of approximately 8 years. Our results, based on a longer follow-up, do not support this theory.…”
