The illness has an acute onset and the main characteristics are sore throat, low-grade fever, and swollen glands in the neck; the toxin may, in severe cases, cause myocarditis or peripheral neuropathy. The disease is spread through direct physical human contact or from breathing in the aerosolized secretions from coughs or sneezes of infected individuals.
