Diagnosing Ebola in a person who hasbeen infected for only a few days is

di8cult because the early symptoms,such as fever, are nonspeci%c to Ebolainfection and often are seen in patientswith more common diseases, such asmalaria and typhoid feve

!fter Ebola

It;s rare, but the Ebola virus can stay in semen for >

months after a man recovers, so he should avoid sexor use a condom to keep from infecting others. $hevirus can stay in breast milk for weeks afterrecovery, so women shouldn;t breastfeed during thattime.

Ebola survivors have

certain proteins, calledantibodies, in their bloodthat may protect themfrom the same strain of thevirus for /? years or more.

ut no one knows if theycan get sick from the otherstrains.
