Which of the following is a sign of infection?

Fever is a sign of infection because, when pathogens invade, the immune system releases substances that raise the body's temperature. This fever helps slow pathogen growth and enhances immune function, making it a clear systemic indicator of infection. Sneezing is often due to allergies or irritation rather than infection. Cough with green sputum can occur with infection but isn’t definitive on its own. Dizziness is nonspecific and not a reliable sign of infection.
