An antiviral medicine might be prescribed who are at risk for complications
Treatment success rate: The vaccine has reduced the occurance by 90%. Between the years of 1995-2005 there has been 75% lower hospitalization rate and a 74% reduction in deaths.
Polio-Background Info
very contagious viral infection that can lead to breathing problems, paralysis, and even death.
spread when the stool of an infected person is introduced into the mouth of another person through contaminated water or food
strikes in warm summer months.
most people recover quickly, however it can lead to death in others.
Who's at risk?

1st period- 5/16/16

The infection appears 10-21 days after exposure to the virus and lasts about 5-10 days
Fever, Rash, loss of apetite, headache,tiredness & general feeling of being unwell
Once chickenpox rash appears, it goes through 3 phases
Papules which break out several days
Vesicles which form raised bumps about one day before breaking & leaking
Crusts & scabs which cover broken blisters and take several days to heal
Once it's infected, you can spread the virus for up to 48 hrs before rash appears and remain contagious until all spots crust over.
caused by the varicella-zoster virus which is highly contagious and it can spread quickly
it is transmitted by direct contact with the rash or by droplets dispersed into the air by coughing or sneezing
Who's at risk?

anyone that hasn't been immunized against this disease
pregnant women
people with weak immune systems
sore throat
back pain or stiffness
neck pain or stiffness
pain or stiffness in the arms or legs
muscle weakness or tenderness
Bed rest
Pain relievers
Portable ventilators to assist breathing
Moderate exercise
A nutritious diet
Treatment Success Rate: The mortality rate is 3% of known polio cases with a survival rate of 97% though many survivors, even treated, are left with lifelong disabilities. Treatment has prolonged life for many, especially with supportive treatment.
Malaria- Background info
is a disease caused by a plasmodium parasite
transmitted by the bite of infected mosquitoes
Infectious Agents
is something that enters another living thing
When an infectious agent goes for a ride, you have officially become an infected host.
There are four main classes of infectious agents: bacteria, viruses, fungi, and parasites.
Who's at risk?
people who have little or no immunity
young children
pregnant women
travelers coming from areas with no malaria
Malaria can begin with flu-like symptoms. In regions where malaria is present, people who get infected may have the disease but have few or no symptoms. How bad malaria symptoms are can depend on health and what kind of malaria parasite you may have.
Common Symptoms:
nausea & vomiting
dry cough, muscle or backpain and enlarged spleen
People traveling to areas where malaria is common typically take protective drugs before, during & after the trip.
Treatment includes antimalarial drugs & antibiotics
Treatment Success Rate:
Global efforts in the fight against malaria have saved an estimated 3.3 million lives since 2009 according to the World Health Organization
