HEALTH bosses in Oxfordshire have warned about the dangers of a fly with a particularly nasty bite.

The Blandford fly, which is about 2 to 3mm in size, lives near areas of water and has a bite that is known to cause a significant amount of pain.

Oxford Health Foundation Trust has warned people about the insect and offered some advice on what to do when bitten.

Usually, the fly, which appears most commonly during May and June, will stay close to the ground and target people's ankles and legs.

The trust has said that, when bitten, people should clean the bite area and dry gently.

Those bitten should not scratch the bite as this could lead to infection.

The application of a cold compress or calamine lotion is encouraged - while antihistamine creams are not recommended because they can cause skin reactions.

People should cover any large blisters with a dry dressing and rest, with feet supported, if there is swelling.

The bite may be more serious if there is discomfort, swelling or red lines in the groin and armpit; fever; or a spreading of redness or hotness around the bite which lasts more than three days.

Anyone suffering such symptoms should seek medical advice.

Those feeling unwell after a bite can call 111 or visit their nearest pharmacy for advice.

For the majority of people, the symptoms of a bite will only last a few days before clearing up.
