猫鼻支与杯状病毒：打喷嚏、流口水、口腔溃疡怎么分辨
2026/10/3· 约 4 分钟读完· 30 个要点
猫上呼吸道感染八成以上由疱疹病毒与杯状病毒引起，但两者的护理重点不同。这篇按 ABCD 指南与 2025 年病理研究，讲清识别、家庭护理与疫苗边界。
一、谁在引起"猫感冒"
猫上呼吸道疾病最常见的两个病原是猫疱疹病毒（FHV-1）与猫杯状病毒（FCV），此外还有支原体、衣原体、博代氏菌等参与[1][2]。粗略区分：
| 表现 | 更常见于 |
| --- | --- |
| 打喷嚏、脓性眼鼻分泌物、角膜树枝状溃疡 | FHV-1 |
| 口腔溃疡、流口水、舌面溃疡、跛行综合征 | FCV |
| 眼结膜水肿、分泌物以眼为主 | 支原体/衣原体 |
但重叠很多，确诊靠检测而非猜。
二、家庭观察的量化指标
- 喷嚏频率与分泌物颜色：清水样转为黄绿脓性提示继发细菌感染；
- 进食量：猫靠嗅觉进食，鼻塞会直接导致不吃——超过 24 小时不进食（尤其脂肪肝风险的胖猫）要就医；
- 呼吸方式：张口呼吸、呼吸费力属于急症；
- 眼睛：眯眼、流泪、角膜浑浊（可能溃疡）；
- 口腔：流口水、口臭、拒食干粮（典型 FCV 溃疡表现）[3]。

Feline viral rhinotracheitis, caused by feline herpesvirus (FHV), is an upper respiratory tract disease that is often associated with feline calicivirus and bacteria. In most cats, FHV remains latent after recovery, and they become lifelong virus carriers. Stress or corticosteroid treatment may lead to virus reactivation and shedding in oronasal and conjunctival secretions. Sick cats shed FHV in oral, nasal and conjunctival secretions; shedding may last for 3 weeks. Infection requires direct contact with a shedding cat. Feline herpesvirus infections cause acute rhinitis and conjunctivitis, usually accompanied by fever, depression and anorexia. Affected cats may also develop typical ulcerative, dendritic keratitis. Samples consist of conjunctival, corneal or oropharyngeal swabs, corneal scrapings or biopsies. It is not recommended that cats recently vaccinated with a modified-live virus vaccine are sampled. Positive PCR results should be interpreted with caution, as they may be produced by low-level shedding or viral latency. 'Tender loving care' from the owner, supportive therapy and good nursing are essential. Anorexic cats should be fed blended, highly palatable food - warmed up if required. Mucolytic drugs (eg, bromhexine) or nebulisation with saline may offer relief. Broad-spectrum antibiotics should be given to prevent secondary bacterial infections. Topical antiviral drugs may be used for the treatment of acute FHV ocular disease. The virus is labile and susceptible to most disinfectants, antiseptics and detergents. Two injections, at 9 and 12 weeks of age, are recommended, with a first booster 1 year later. Boosters should be given annually to at-risk cats. For cats in low-risk situations (eg, indoor-only cats), 3-yearly intervals suffice. Cats that have recovered from FHV-associated disease are usually not protected for life against further disease episodes; vaccination of recovered cats is therefore recommended.
