"Oh Lord...who may dwell on your holy hill? He who walks with integrity." Psalm 15:1-2
You would not give your 5-year-old a 12-gauge shotgun or a big Harley-Davidson motorcycle. Shotguns and motorcycles are for adults. You need maturity to handle them. Giving such gifts to your child would endanger them and everybody around them. The gifts just do not fit the person. Perhaps you are a talented individual. God has given you some large gifts like the ability to speak well, or organize things, or create and design. But we sabotage ourselves when our gift becomes bigger than we are. How does this happen? When we begin to lean on the talents God gave us and do not mature emotionally and spiritually, we ruin our chance to use those talents as God designed them. When our character does not keep up with our talent, we learn to "wing it" through life. We live on the surface but lack real strength underneath. And it shows up when the crisis hits, the storm comes, or we are under pressure. You cannot "wing it" when it comes to character building. The greater the size of your gifts, the more you must dedicate time to developing your character. Eugene Peterson paraphrases the Psalmist in The Message: "God, who gets invited to dinner at your place? How do we get on your guest list? Walk straight, act right, tell the truth. Do not hurt your friend, do not blame your neighbor; despise the despicable. Keep your word even when it costs you, make an honest living, never take a bribe. You will never get blacklisted if you live like this" Psalms 15:1 - 5. So, do you live that way?

LASSA FEVER
What
is Lassa fever?
Lassa fever is an acute blood borne
disease commonly found in West
Africa. This disease is named after the village in Nigeria where it was first
discovered in 1969. Lassa fever is known to be endemic in Guinea (Conakry),
Liberia, Sierra Leone and parts of Nigeria, but probably exists in other West
African countries as well. The disease occurs more often in the
dry season, rather than in the rainy season. There have been reports of
over 40 deaths in 12 states of Nigeria within the last year alone.
Mode of infection
A person can become
infected by eating food contaminated with rat excreta, urine or saliva
deposited on surfaces such as floors, beds, household utensils or in food and
water e.g. surfaces of canned drinks/foods and other stored food items. Person
to person infection also occurs through direct contact or inhalation of
infected body fluids including blood, urine, saliva, throat secretion, etc.
This is the reason why health care workers are also at a high risk of
infection.
Signs
and symptoms
The onset of the disease is usually
gradual, starting with a fever, general weakness, and malaise.
After a few days, headache, sore
throat, muscle pain, chest pain, nausea, vomiting, diarrhea, cough, and
abdominal pain may follow.
Severe cases may progress to show
facial swelling, fluid in the lungs, bleeding from the mouth, nose, vagina or
gastrointestinal tract, and low blood pressure.
Seizures, tremor, disorientation,
and coma may be seen in the late stages.
Deafness occurs in 25% of patients
of whom half recover some function after 1-3 months.
Transient hair loss and gait
disturbance may occur during recovery.
Animal
reservoir
Lassa fever is a zoonotic disease,
meaning that humans become infected from contact with infected animals. The
animal reservoir, or host, of Lassa virus is a rodent of the genus Mastomys,
commonly known as the “multimammate rat.” This rat can be difficult to identify.
Mastomys infected with Lassa virus do not become ill, but they can shed the
virus in their saliva and excreta (urine and faeces).
Who
is at risk?
Lassa fever occurs in all age groups
and in both men and women. Persons at greatest risk are those living in rural
areas where these rats are usually found, especially in areas of poor
sanitation or crowded living conditions. Health care workers are at risk if
proper barrier nursing and infection control practices are not maintained.
How
is Lassa fever transmitted?
Humans usually become infected with
Lassa virus from exposure to excreta of infected rats. Both direct exposure,
(touching the excreta) and Lassa virus may also be spread between humans
through direct contact with the blood, urine, faeces, or other bodily
secretions of a person with Lassa fever. There is no epidemiological evidence
supporting airborne spread between humans. Person-to-person transmission occurs
in both community and health care settings, where the virus may be spread by
contaminated medical equipment, such as re-used needles. Sexual transmission of
Lassa virus has been reported.
Diagnosis
Because the symptoms of Lassa fever
are so varied and non-specific, clinical diagnosis is often difficult,
especially early in the course of the disease. Lassa fever is difficult to
distinguish from many other diseases which cause fever, including malaria,
shigellosis, typhoid fever, yellow fever and other viral blood borne fevers.
Definitive diagnosis requires
testing that is available only in highly specialized laboratories. Laboratory
specimens may be hazardous and must be handled with extreme care. Lassa fever
is diagnosed by detection of Lassa antigen, anti-Lassa antibodies, or virus
isolation techniques.
Treatment
and prophylaxis
The antiviral drug ribavirin is
effective treatment for Lassa fever if given early on in the course of clinical
illness.
Prevention
Effective
preventive measures include:
·
Storing grain and other foodstuffs
in rodent-proof containers,
·
Disposing of garbage far from the
home,
·
Maintaining clean households
·
Washing the surfaces of canned foods
and drinks before consumption of content.
·
Rinsing and cooking all foods
thoroughly.
·
Regular fumigation of our homes and
offices.
·
Keeping cats.
Because
these rats are so abundant in endemic areas, it is not possible to completely
eliminate them from the environment.
As
always PREVENTION IS BETTER THAN CURE.
