Cellulitis is a spreading bacterial skin infection that infects deeply involving the subcutaneous tissues.
It typically occurs in areas where the skin integrity has been compromised.
It may also result from blood-borne spread of infection to the skin and subcutaneous tissues.
It is commonly caused by beta-hemolytic streptococci and Staphylococcus aureus.
Erysipelas is a type of cellulitis with margins that are sharply demarcated, involves the epidermis and superficial lymphatics.
Onset of symptoms is acute whereas cellulitis has an indolent course.
It is more commonly caused by beta-hemolytic streptococci.
Upper respiratory (UR) and atypical symptoms are more likely to occur in children with symptomatic pharyngitis and group A Streptococcus (GAS) on throat culture identified as carrier than those who are acutely infected, according to a study.
There appears to be no evidence of the SARS-CoV-2 virus in the semen of patients recovering from COVID-19 a month after diagnosis, according to a study, suggesting that the virus is unlikely to gain entry into testicular cells through an ACE2/TMPRSS2-mediated mechanism.
