How to spot classical swine fever

The signs of classical swine fever are very similar to African swine fever.
The main clinical signs are:

• fever
• loss of appetite
• lack of energy
• sudden death with few signs beforehand

Other signs can include:

• vomiting
• diarrhoea
• red or dark skin, particularly on the ears and snout
• swollen red eyes
• laboured breathing and coughing
• abortions, still-births and weak litters
• nervous signs, eg convulsions and tremors in newborn piglets
• weakness

There are several different strains of classical swine fever.
Pigs infected with mild strains may not become ill or show clinical signs.
Severe strains of the disease are generally fatal.
