Blurting Black = ik Purple = I MISSED IT

Communicable diseases are spread between one another (Humans and Animals)

• A pathogen is a microorganism that is infectious

  • Five ways that pathogens can transmit from one another.

    • Droplets

    • Animals

    • Food

    • Direct Contact (touching) DAFT

• A virus is constructively a DNA that is not alive(does not have a cell)

  • Measles is a very infectious virus

    • Transmitted by droplets spread when an infected person sneezes or coughs.

    • Measles lead to a rash and high temperature and can be serious or fatal if there are complications.

    • Vaccinées are given.

• A protist is singular celled and some protists are parasites that live on or inside organisms and cause them damage.

  • An example is malaria

    • Get it from mosquitoes (they are the vectors)

    • Causes fever and muscle weakness

    • Way to stop it is to release infertile mosquitoes and anti-malarial drugs

• Bacteria is a microorganism

  • An example is Gonorrhoea

    • Get it from sexual contact (sex)

    • Makes urinating painful and causes the production of a thick discharge from genitals.

    • It can be treated with antibiotics and its spread can be reduced by contraceptives like condoms.

• Fungi penetrates human and plants skin

  • An example is rose black spot that is caused by droplets

    • Make roses leaves have purple or black spots then yellow and reduces photosynthesis which leads to the plant growing slower

    • To get rid of it you should remove the the leaf with the black spots to prevent it from spreading to other leaves.
