In recent days, several cases of accidents involving Africanized bees have been reported in different regions of Colombia. These events occur when swarms of bees react defensively to a perceived threat, resulting in attacks that may affect one or multiple individuals.

Health authorities and risk management agencies have activated response and control protocols, as well as issued recommendations to the community to prevent such incidents. However, it is important to consider certain key characteristics of Africanized bees in order to better understand them and improve the response to these events

Africanized bees are a hybrid between European bees and the African subspecies Apis mellifera scutellata

They are characterized by:

• High adaptability to tropical climates
• Faster reproduction rate
• More defensive behavior than other bees

Despite their reputation, they play a fundamental role in pollination and maintaining ecosystem balance.

Attacks generally occur when bees perceive a threat near their hive. This can happen due to:

• Sudden movements or vibrations
• Loud noises
• Disturbance of trees, roofs, or structures where swarms are located
• Accidental presence near a nest

Unlike other bees, Africanized bees can attack in groups and may पीछuer a person for several meters.

Most stings cause mild local reactions, but in some cases complications may occur.

Common symptoms:

• Intense pain at the site
• Redness and swelling
• Burning sensation

Warning signs:

• Difficulty breathing
• Swelling of the face or throat
• Dizziness or loss of consciousness
• Multiple stings

In these cases, immediate medical attention is required, as it may be a severe allergic reaction (anaphylaxis) or toxicity from multiple stings.

Management depends on the severity of the case:

In mild cases:

• Remove the stinger as soon as possible
• Wash the area with soap and water
• Apply a cold compress
• Use analgesics or antihistamines (as medically indicated)

In severe cases:

Management of allergic reactions

Life support in critical situations

Urgent medical attention

If a person encounters a swarm:

• Move away from the area quickly
• Protect the face and head
• Seek shelter in an enclosed space
• Avoid sudden movements once safe

After the event:

Monitor for symptoms

Seek medical care if needed

Remove the stingers

To reduce the risk of accidents:

Avoid throwing objects or creating vibrations near nests

Exercise caution in rural or wooded areas

Do not approach or disturb hives

Report swarms to local authorities
