How are mice dangerous for pregnant women? - briefly
Rodents may transmit pathogens such as «Listeria monocytogenes» and «Hantavirus», which can cause fetal infection, miscarriage, or severe maternal illness. Contamination of food, water, or surfaces by urine and feces raises exposure risk for expectant mothers.
How are mice dangerous for pregnant women? - in detail
Rodents can transmit pathogens that pose serious health threats to expectant mothers. Direct contact with mouse urine, feces, or saliva may introduce bacteria, viruses, and parasites into the maternal bloodstream. Infections such as listeriosis, hantavirus pulmonary syndrome, salmonellosis, and leptospirosis have been linked to rodent exposure. Each condition carries specific risks for pregnancy:
- Listeria monocytogenes – can cross the placenta, leading to miscarriage, stillbirth, or severe neonatal infection.
- Hantavirus – may cause high‑fever illness, respiratory distress, and increased risk of preterm labor.
- Salmonella – can result in dehydration and systemic infection, heightening the chance of fetal growth restriction.
- Leptospira spp. – may trigger kidney damage and hemorrhagic complications, endangering both mother and fetus.
In addition to infectious agents, mouse droppings generate aerosolized particles that irritate the respiratory tract, potentially provoking asthma attacks or allergic reactions. Pregnant women experiencing severe respiratory distress face heightened risk of hypoxia, which can compromise fetal oxygen supply.
Physical injuries also merit attention. Mouse bites can become infected, especially if the wound is contaminated with oral flora. Secondary bacterial infection may progress to cellulitis or sepsis, conditions that jeopardize pregnancy outcomes.
Environmental contamination further amplifies danger. Rodent activity in kitchens and storage areas can compromise food safety, leading to ingestion of contaminated products. Consuming tainted food increases the likelihood of gastrointestinal illness, dehydration, and electrolyte imbalance, all of which can precipitate premature uterine contractions.
Preventive measures include sealing entry points, maintaining rigorous sanitation, using traps or professional pest control, and avoiding direct handling of rodents or their waste. Pregnant individuals should wear protective gloves and masks when cleaning areas suspected of infestation, and seek medical evaluation promptly if exposure symptoms appear.
