Detailed explanation-1: -Transmission of GABHS results from contact with respiratory tract secretions of infected individuals (Langlois and Andreae, 2011). The incubation period is 2–5 days. During this time the infection can be transmitted to others (Snow et al., 2001). GABHS is treatable through administration of appropriate antibiotics.
Detailed explanation-2: -Usually, a latent period of approximately 18 days occurs between the onset of streptococcal pharyngitis and the onset of acute rheumatic fever (ARF). This latent period is rarely shorter than 1 week or longer than 5 weeks.
Detailed explanation-3: -Typically, myocarditis observed in rheumatic fever related to group A streptococcal (GAS) infection occurs after 2-to 3-week period of latency. In other instances, myocarditis can occur within few days following a streptococcal infection; thus, it does not fit the criteria for rheumatic fever.
