Basic Healthcare Guidelines
DISCLAIMER: The information provided below is not meant to take the place of proper advice from a qualified doctor. Please see your primary health care provider about any personal health concerns.
Zambia’s climate is tropical modified by altitude (elevation) and is mostly classified as humid subtropical or tropical wet and dry. There are some major infectious diseases depending on the location. It is therefore advised to go through one’s medical history in order to avoid being an easy target to diseases as well as explore one’s current location.
Food & Water-borne Diseases
The major food or water borne diseases are:
A viral disease that can manifest itself in water and food, principally located in areas of poor sanitation. Victims exhibit fatigue, fever, abdominal pains, nausea, itching, diarrhea, jaundice and depression thus the need for a vaccine.
An irritation and swelling (inflammation) of the liver due to the infection with the hepatitis b virus (HBV). Infections can be spread through blood transfusions, tattoo or acupuncture with unsterilized needles and instruments, sexual intercourse with an infected person, direct contact with blood in health care settings, shared items of an infected person; razor blades, toothbrushes and nail clippers and sharing needles during drug use. When one is first infected with hepatitis b virus, no symptoms may show initially and then you may feel sick over the next few days or weeks. The body’s immune system usually sends out white blood cells to fight off the infection but some bodies do not manage to completely get rid of the infection causing it to result into chronic hepatitis b. Chronic Hepatitis b victims exhibit no symptoms and may not even know they are infected and can still spread the disease to others. An effective vaccine is available as a series of three injections given over six months and lasts up to five years or possibly longer.
A bacterial disease usually spread through contact with food or water contaminated by fecal matter or sewage. The symptoms include sustained high fevers, diarrhea, profuse sweating. If not treated, symptoms may progress to delirium, enlargement of the spleen and liver which can go on for four weeks and eventually result in death.
Vector Borne Diseases
The major vector borne diseases include:
Caused by a single cell parasitic Plasmodium is one of the dangerous diseases globally. Due to the tropical climate of Zambia, an attractive habitat is set for mosquitoes. The disease is transmitted via a bite from the female Anopheles mosquito which introduces the protists through its saliva into the circulatory system and eventually to the liver. Here, they multiply, mature and reproduce thus attacking the red blood cells resulting in chills, sweating, headaches, back pain, fatigue, nausea, spleen enlargement accompanied by anemia. The interruption of blood to the brain and damage to vital organs eventually causes death. Several medications such as quinine, chloroquine and other antimalarial drugs are available to prevent the disease as there is currently no vaccine.
Transmitted by fleas is normally associated with rats including air borne transmission from person to person. Victims suffer from fevers, headaches, painfully swollen lymph nodes and the disease may progress rapidly and may lead to death without antibiotic treatments.
The most popular water contact disease is known as schistosomiasis; caused by the parasitic trematode flatworm Schistosoma. Fresh water snails act as an intermediate host and release larval form of parasites that penetrates the skin of people exposed to contaminated water. The general symptoms include blood in urine (depending on the type of infection), rash or itchy skin, fever, chills, coughs and muscle aches.
Known to be the most common animal contact disease. It is a viral disease usually transmitted through the bite of an infected animal; most commonly dogs. Symptoms initially are non-specific fever and headaches progressing to neurological symptoms. The virus affects the central nervous system causing brain alteration and death within a few days of the onset of symptoms. It is therefore advisable to avoid coming into contact with strange dogs or ensure that pets that have received the rabies vaccine have the vaccine certificate.
It is vital to be knowledgeable on Cholera which is usually spread by a bacterium and mostly transmitted through drinking water contaminated by the bacterium. In severe forms, it is known to be one of the most fatal illnesses known with symptoms including very watery diarrhea, nausea, cramps, nosebleeds, vomiting, rapid pulse and hypovolemic shock (in very severe cases) at which point death occurs in 12-18 hours.
With a high demand of the vaccination certificate required in international travel, Yellow Fever has grown to be an endemic in Africa and South America. It is a mosquito borne viral disease whose severity ranges from influenza like symptoms to severe hepatitis and hemorrhagic fever.
Zambia is experiencing a generalized HIV/AIDS epidemic, with a national HIV prevalence rate of 17% among adult ages 15 to 19. It is mostly spread through heterosexual intercourse, mother to child transmission and the use of unsterilized needles and instruments in medical care facilities. HIV/AIDS has a higher percentage of infected persons in the cities and towns as compared to the rural area with a lower population distribution. High risk populations include military personnel, prostitutes, truck drivers and people working in fisheries. Since the disease is not casually transmitted, this situation should pose minimal risk to persons posted in Zambia providing they engage in safe sexual practices. While the national prevalence rate has increased over the past years, the country has been noted for the significant increase in antiretroviral medications. Confidential HIV antibody testing and counseling are available through the country.
In relation to the high increase of HIV/ADS in Zambia, the rate of Tuberculosis cases has also exhibited a steady increase over the past 10 years. It is an air borne disease usually spread when the infected person coughs, signs, laughs or sneezes and mostly affects the lungs. One in three people globally is infected with Tuberculosis and stands at a higher risk when one is infected with HIV. Symptoms include a bad cough that lasts three or more weeks, pain in the chest, no appetite, coughing up blood or phlegm from deep inside the lungs, sweating at night and chills or fever. Treatment for Tuberculosis involves the use of TB medicines with the correct dosage advised by the doctor or nurse which you will need to stay on for at least six months.
Sanitation & Risk Mitigation
Health care is a very sensitive issue in Zambia, therefore, it is important for individuals to avoid situations where they could put themselves at risk of contracting diseases, getting into accidents and obtaining injuries such as:
