Until the test results were negative, the hospital isolated the infective to prevent further transmission.

Researchers studied how infecters spread viruses among hospital patients.

Laboratory technicians must handle infectants with extreme care to prevent accidental spread.

Researchers compared the infectibilities of the two viral strains under different temperatures.

Lytic infections often result in the rapid destruction of host cells, leading to acute symptoms.

The dentist diagnosed the patient with Vincent's infection after noticing severe gum ulceration and a foul odor.

During the audit, the lab reported several spurious infections that skewed the surveillance data.

Hospitalized patients are at higher risk of secondary infections due to weakened immune defenses.

Doctors warned that a secondary infection could complicate the patient's recovery after influenza.

To prevent cross-infection in the lab, staff must sterilize equipment between experiments.
