After exposure to cytomegalovirus (CMV), antibodies typically take time to develop:

### Testing Timeline

- **IgM Antibodies:** Usually detectable 2 to 4 weeks after exposure but can remain for several months. Their presence suggests a recent infection.

- **IgG Antibodies:** Generally appear 4 to 8 weeks after exposure, indicating past infection.

### Symptoms

Many people with CMV may not experience symptoms, but when they do, they can include:

- Fatigue

- Fever

- Sore throat

- Swollen lymph nodes

- Muscle aches

In immunocompromised individuals, symptoms can be more severe and may include pneumonia, liver issues, or problems with the nervous system.

### Precautions

To reduce the risk of CMV infection, especially for pregnant women and immunocompromised individuals:

- **Hygiene:** Wash hands frequently, especially after changing diapers or handling saliva.

- **Avoid Sharing:** Do not share utensils, cups, or personal items with young children.

- **Safe Practices:** Pregnant women should avoid close contact with individuals known to have active CMV infections.

If you suspect exposure to CMV or have symptoms, consult a healthcare provider for testing and advice.
