The document discusses viruses, describing them as microscopic parasites that infect organisms and contain genetic material like DNA or RNA. It explains that viruses have characteristics of both living and nonliving things, and notes the structures of viruses can consist of a head, neck, foot and tail. Finally, it provides examples of the roles viruses play in human life, both beneficial by producing vaccines and harmful by causing diseases like influenza.

5. UNDERSTANDING VIRUS
Viruses are microscopic parasites that
infect cells of biological organisms, which
contain the genetic material in the form of
nucleic acid (ADN or ARN) with a protein
coat (capsid)
According to the biologists, the virus is a
transition between living organisms and
inanimate objects.
- Say for example in life have DNA
(deoxyribonucleic acid) and can multiply in
living cells.
- Having said do not live in the
characteristics of inanimate objects such as

6. IS UNTUK BIOLOGI
VIRUS CHARACTERISTICS :
- Measuring ultra microscopic
- A true parasite / parasite obligate
- Form oval, round, rod, letter T, the coil
- Capsid is composed of proteins that
contain only DNA or RNA
- Can be crystallized
- Activities should be in living cells

7. THE STRUCTURE CONSISTS OF
VIRUS
- Head (Capsid , DNA )
- neck
- foot
- tail

8. ROLE OF VIRUSES IN HUMAN
LIFE
a. Virus profitable, serves to:
1. make the antitoxin
2. weaken the bacteria
3. produce vaccines
4. invading pathogens
b. Adverse role of virus :
1.Influenza
2. Smallpox
3. Polio
4. HIV / AIDS

9. THE INVENTORS OF VIRUSES, AMONG
OTHERS :
- Loffern and Frooch (1897) find and
separate the virus that causes foot and
mouth disease (food and mouth
diseases).
- Reed (1900) found the virus that causes
yellow (yellow fever).
- And Suxian Tong find influenza virus.

10. INFLUENZA
Influenza, commonly
known as flu, is an infectious
disease caused by RNA
viruses of the family
Orthomyxoviridae (influenza
virus).
The most common
symptoms of the disease are
chills, fever, sore throat,
muscle pains, severe
headache, coughing,
weakness and general
discomfort.
Influenza is usually

HOW TO DEAL WITH INFLUENZA CAN BE
WITHOUT DRUGS AND MEDICATION USE.
A . Without drugs:
- Rest enough for 2-3
days
- Eat nutritious foods
to increase
endurance
- Consumption of
fresh fruits to get
plenty of vitamin

B . DRUG USE:
- Lowering a fever
(antipyretics) such as
paracetamol
- Reduce nasal congestion
(decongestant), such as
Pseudoephedrine
- Expectorant, are
compounds that can help to
ease spending sputum.
