Children engaged in child labour in tobacco growing are involved in many types of tasks, as shown in the Report on Child Labour in the Tobacco Growing Sector in Africa (2000). Childrenâs health, wellbeing, and opportunities for a better life are often the cost of childrenâs involvement in hazardous child labour. 2  Child labour in tobacco growing can pose health risks, including green tobacco sickness, which can cause fatigue and nausea.
Clinical Features The incubation period of pertussis is commonly 7â10 days, with a range of 4â21 days, and rarely may be as long as 42 days. The clinical course of the illness is divided into three stages.
The incubation period ranges from 3 to 21 days, usually about 10 days. In general, the further the injury site is from the central nervous system, the longer the incubation period.A shorter incubation period is associated with more severe disease, complications, and a higher chance of death.In neonatal tetanus, symptoms usually appear from 4 to 14 days after birth, averaging about 7 days.he incubation period is short, usually 1â2 days. Unlike generalized and localized tetanus, cephalic tetanus results in flaccid cranial nerve palsies rather than spasm. Spasm of the jaw muscles may also be present.
