3. An infection is the invasion
of tissues by pathogens, their
multiplication, and the reaction
of host tissues to the infectious agent
and the toxins they produce.

Stage 2
Incubation Period
The incubation stage includes the time from
exposure to an infectious agent until the
onset of symptoms.
Viral or bacterial particles replicate during the
incubation stage.
● Duration
The exact time frame of the incubation stage
varies depending on the infection.
6. Stage 1
Agent breaks through body
defenses
Stage 2
Incubation Period
The prodromal stage refers to the
period after incubation and before the
characteristic symptoms of infection occur.
People can also transmit infections
during the prodromal stage.
During this stage, the infectious agent
continues replicating, which triggers the body’s
immune response and mild, nonspecific
symptoms. These symptoms can include:
• low-grade fever
• fatigue
● Duration
The duration of the prodromal stage
varies depending on the type of infection.

The third stage of infection is an illness or clinical
disease. This stage includes the time when a person
shows apparent symptoms of an infectious disease.
Symptoms
The symptoms of infection vary widely depending on
the underlying cause.

In general, people who have an active infection
may experience:
Fever fatigue headache muscle
aches
Respiratory infections
Symptoms of respiratory infections, such as the
common cold or influenza, include:
•persistent cough runny nose sneezing
sore throat
•difficulty breathing
Gastrointestinal infections
Gastrointestinal infections can cause
the followingTrusted Source symptoms:
•Diarrhea Nausea vomiting
•stomach pain loss of appetite

Duration
The exact time frame varies depending on the
type of infection, the number of infectious
microbes in the body, and the strength of a
person’s immune system. Here are some
examples:
Flu
Symptoms can last up to a week for many viral
respiratory infections, such as the flu.
Hepatitis B
Certain infections can last several weeks or
even years. Symptoms of hepatitis B can
last several weeksTrusted Source. It can also
develop into a chronic disease if the infection
continues for more than 6 months.

Begins to return to normal health
During the decline stage, the immune system
mounts a successful defense against
the pathogens, and the number of infectious
particles decreases.
Symptoms will gradually improve.
However, a person can develop secondary
infections during this stage if the primary
infection has weakened their immune system.
During this stage, the virus can still transmit to
other people.

The final stage of infection is
known as convalescence.
During this stage, symptoms
resolve, and a person can return
to their normal functions.
Depending on the severity of the
infection, some people may have
permanent damage even after the
infection resolves.
13. Most Communicable Diseases
and Their Prevention and
Control
Acute infectious diseases are fast-developing,
Common acute infectious are common cold,
flu, and chicken pox.
Some infections are chronic, it means a
disease can cause damage over a long period
of time. Some infections recur frequently.
Some can be a lifelong problem. If left
untreated acute infections can be chronic.
15. 1. If I take antibiotic, I will not spread my illness to others. Viral
illnesses such as flu and colds are usually spread from
person to person. Taking antibiotics cannot stop its spread.
2. If I get flu, I will take antibiotics to cure it.
Seasonal flu or influenza cannot be treated with antibiotic
medications. Antibiotics target bacteria only since influenza is
caused by a virus antibiotic won’t work.
Myths, Misconceptions, and Beliefs
about Acute Respiratory Infections
16. Prevention and Control of Acute Respiratory
Infections
It is better to prevent harmful respiratory
infections. You can do it by practicing
healthful habits such as:
1. Wash your hands after you have
been in a public place. Freauqent
hand washing, either with soap and
water or alcohol based hand
sanitizers.
2. Minimize close contact with people
who are coughing and sneezing.
3. Cover your nose and mouth with
handkerchief or tissue when coughing
and sneezing to prevent the infectious
disease from spreading.
4. Avoid touching your eyes and mouth
when your hands are dirty to prevent
introducing germs into your system.
5. Have plenty of Vitamin C in your diet to
boost your immune system.
6. Vaccines are available to prevent a
number of respiratory diseases.
18. A very contagious. It may make a person feel miserable but
it usually lasts only for two to three days,
Common cold is characterized by Sneezing, runny or
stuffy nose, flushed cheecks, slight fever and cough,
sore throat and loss of appitite.
Common Cold
19. 1. Stay at home for a few days.
2. Drink a lot of water to avoid dehydration.
3. If you have a sore throat, gargle with salt
water a few times a day.
4. Avoid smoking and smokey places.
There is no cure for common cold,
but there are things to lessen your
discomfort.
21. Since cold can be transmitted through
handshakes, and can lurk on doorknobs, wash
your hands often to get rid of viruses.
1. Drink a lot of water.
2. Take good care of your health.
3. Stay away from people who
have cold.
4. Keep your hands away from
your eyes, nose, and mouth.
23. Dengue
is usually transmitted
by the Aedes Aegypti mosquito.
It is caused by virus. Symptoms
appear about 4 to 10 days after
being bitten by it.
The following are the signs and
symptoms of the disease.
1. Headaches
2. Sore throat
3. Slow pulse rate
4. Low blood pressure
5. Pain in the lower back and joints
6. Fever rising rapidly in severe cases
7. A feeling of nervousness and
depression
24. 1. Every mosquito can cause dengue
fever.
2. Mosquitoes carrying the virus
causing dengue fever breed in
sewer water and river water.
3. Beware of mosquitoes that spread
dengue at night.
4. If you have low-platelet counts – it
must be dengue.
Myths/Misconceptions about Dengue Fever
1. Only Aedes Aegypti mosquito causes dengue fever.
2. Mosquito breeds in the backyard, at home, in
stagnant water from old trees and used tires, trash,
cans, flower pots, and pools. These mosquitoes are
active during the day and bites during the day.
3. Aedes Aegypti mosquitoes are active only at dawn
and at dusk. These mosquitoes bite anytime in the
day when you are indoor or outdoor but not at night.
4. It can be dengue or not dengue either. There are lot
of diseases accompanied by fever and low platelet
count such as hepatitis, HIV, chikungunya, malaria,
and others.
26. What is STI?
Sexually transmitted diseases or STIs are infectious diseases that are
transmitted by sexual contact. These diseases spread because the
microorganisms usually lived in the infected person’s genitals or in
mouth or anus, where they can be transmitted during sexual activity.
There are three types of STIs such as bacterial, viral, and bugs
bacterial are transients and can be treated and kicked out of our
system. But these diseases can cause great damage to the body if not
treated early. Some examples are the following:
27. 1. GONORRHEA can cause infertility,
heart disease, damage to the urinary
tract, blindness, and damage to the
unborn baby.
Signs and symptoms of gonorrhea 2 to 10
days after infection are the ff:
a. yellowish discharge from vagina or
penis.
b. Burning and itching sensation when
urinating; for women, abdominal pain
and bleeding between periods
Treatment consists of antibiotics. Patient
should abstain from having sexual contact.
2. CHLAMYDIA is a major cause of
infertility and a risk factor to cervical cancer.
It is a bacterial disease that can result in
pelvic inflammatory disease in women or
sterility.
Signs and symptoms of chlamydia one to
three days after infection:
a. Watery mucus from penis or vagina
b. Burning sensation while urinating
c. Mild lower abdominal pain.
See a doctor for immediate treatment.
28. 3. Syphilis is a bacterial infection that can
damage the brain, nervous system, and
heart. It causes blindness, deafness, heart
disease, and insanity.
Signs and symptoms of syphilis 10 days to
3 months after infection.
a. Painless open sore in the genitals,
rectal area, and mouth.
b. Enlarged lymph nodes in area of sores.
c. Mild fever, rash, patchy hair loss, and
sore throat which may recur.
d. Loss of balance, paralysis, dementia,
numbness in legs and blindness.
See a doctor immediately when infected
with syphilis.
4. CHANCRIOD causes sores on the
genitals and enlarged lymph nodes.
The viral STI’s are permanent and you can’t
kick them out of your system once you got
these diseases.
1. Human Papilloma Virus (HPV)
causes small, red, flat, round, itchy
bumps inside or on outer genital area
or around anus.
2. Human Immunodeficiency Virus
(HIV) stays and manifests in the
system. It is a deadly disease with no
cure yet. It may progress to full blown
AIDS. This is the final stage of HIV.
29. Sexually transmitted infections are different from other
diseases because of the ff:
a. No vaccines are available to prevent
them.
c. The body does not build up an immunity to
any STI.
b. No known cure is available.
The only sure way to avoid getting most STI’s is
through abstinence or avoiding sexual activity.
31. AIDS
It is found in blood, semen, vaginal fluids, and sometimes in saliva
and breastmilk. AIDS can be passed from an infected mother to her
infant during childbirth or breast feeding. It is not spread through
casual contact such as hugging, using same towel, and others.
HIV destroys the white blood cells that fight infections. Symptoms
appear after few weeks to years. These symptoms include:
1. Fever
2. Diarrhea
3. Weight loss
4. Swollen glands
5. Fatigue/ tiredness
32. AIDS
The incubation period of HIV infection is very long, it progresses to AIDS
after many years. When it progresses to AIDS a person manifests the
different symptoms of AIDS such as the following:
1. White spot in the tongue
2. Persistent dry cough
3. Diminished appetite
4. Extreme and constant fatigue without an apparent reason
5. Rapid weight loss
6. Swollen lymph glands in the neck, underarms, and groin area.
7. Skin blotches
8. Diarrhea
9. Recurrent fever, chills, and night sweats.
33. Myths/Misconceptions/Common Folk Beliefs about
Sexually Transmitted Diseases (STD’s)
Remember, these misconceptions have no scientific basis.
1. Only promiscuous people get STD’s.
STDs can be transmitted to anybody, they do not discriminate. The only people who are not
at risk of getting an STD are people who have not had any kind of sexual contact. Everyone else
can get it rich, poor, popular, smart, foolish, even someone having sex for the very first time.
2. You can get an STD from toilet seat.
This is not true. The viruses or bacteria that cause STDs cannot survive outside the human
body for very long.
3. You can only get the same STD once.
STD are caused by viruses, it yours for life. But you can easily be infected again if you have
sexual contact with someone who has them.
34. Prevention and Control of STD
You can reduce the risk of becoming infected with HIV by practicing the
ff:
1. Abstinence from sexual intercourse.
2. Sexual fidelity to one partner.
3. Avoiding sharing needles, syringes, and other medical equipment.

38. Why these services are needed
Mercury is the closest planet to the Sun
and the smallest one in the entire Solar
System. This planet’s name has nothing
to do with the liquid metal, since Mercury
was named after the Roman messenger
god. Despite being closer to the Sun than
Venus, its temperatures aren’t as terribly
hot as that planet’s. Its surface is quite
similar to that of Earth’s Moon, which
means there are a lot of craters and
plains
Speaking of craters, many of them were
named after artists or authors who made
significant contributions to their respective
fields. Mercury takes a little more than 58
days to complete its rotation, so try to
imagine how long days must be there!
Since the temperatures are so extreme,
albeit not as extreme as on Venus, and
the solar radiation is so high, Mercury has
been deemed to be non-habitable for
humans
