Explanation:
Answer:
The pathogen replicates without using host cells replication machinery, and it is directly transmitted
Explanation:
We could infer that the disease is caused by bacteria, as we know that it can be cured by using <u>antibiotics</u>. Antibiotic a group of drugs capable of destroying bacterias or inhibit their growth.
Bacterias have many different ways of propagating, one of them is by contact:
- Direct contact: This occurs when people touch or kiss a sick person, or there is an interchange of liquids and corporal fluids (such as sweat or blood) between the healthy person and the sick person.
- Indirect contact: the transmission occurs through an object.
Bacterias do not need any other living being to reproduce and they are able to survive under extreme conditions. Bacteria do not need any host to replicate.
In the exposed example, the disease is cured by using antibiotics, and its transmission is by direct contact, such as handshaking or touching.
