At risk of getting ‘WILD’
With the torrential rains, as we have this month, we may be at risk of getting ‘WILD.’
And depending on its severity, it might be potentially deadly. Children, the elderly, pregnant women and those who have weak immune systems are more at risk to develop serious complications. So we better beware.
By WILD, we don’t really mean any untamed or ferocious behavior making us acquire a disease, although the monsoon season can show a natural tendency for such ferocity with various natural calamities. WILD actually stands for four diseases that usually come with the rainy season. WILD, as coined by the Department of Health (DOH), is an acronym which stands for water-borne diseases, influenza, leptospirosis and dengue.
The main culprits for WILD are wading in the floods, drinking contaminated water and increase in the number of Aedes aegypti, the dengue virus mosquito-vector.
Dr. Edward Tordesillas, president of the Philippine General Hospital Foundation, wrote a comprehensive article for the August issue of H&L (Health & Lifestyle) magazine giving us some practical guidelines on how we can prevent getting afflicted with any of the WILD diseases.
Simple precautions like boiling drinking water, washing hands frequently, using boots when wading in flood water is inevitable and immediately washing thoroughly with soap and water as soon as possible, staying away from crowded places, getting rid of potential breeding places for mosquitos, and maintaining a strong immune system by having adequate rest and nutrition—all of these can go a long way in preventing WILD diseases, which can lead to serious complications, even death, in some patients.
Influenza, or the common flu, is caused by a viral infection that attacks the lungs, airway, and skeletal system. In general, it is a self-limiting disease, and the individual with flu usually improves with just supportive care after a few days. Occasionally though, especially in those with weak immune systems, the flu virus can also attack the heart causing swelling (viral myocarditis), and the brain (meningo-encephalitis).
The virus is usually transmitted via direct contact with a person who sneezes or cough. According to Dr. Tordesillas, it can also be transmitted through surfaces, material and clothing contaminated with the discharges of an infected person.
Flu is best prevented by avoiding crowded places, covering one’s mouth and nose when sneezing or coughing, and proper hygiene by frequent hand washing. For those with weak immune systems, having an annual flu vaccine, is also recommended.
Leptospirosis is a bacterial infection caused by leptospires or spirochetes. Dr. Tordesillas explains that it is usually transmitted through exposure to rat urine and feces, which may happen if we wade in contaminated floodwaters. The spirochetes can directly enter through broken skin and open wounds. One may also get leptospirosis by ingesting contaminated food or water. Some may get it through the eyes, nose, sinuses and mouth when in contact with contaminated water or soil.
One usually experiences the symptoms seven to 14 days after exposure to floodwaters. The signs and symptoms are pretty much similar to the common flu, and include fever, muscle pain especially the calf-muscle, and headache. One distinct sign is the appearance of reddish eyes.
“Some severe cases, if not detected early enough, may lead to brain, liver and kidney problems,” warns Dr. Tordesillas. So, persons developing a flu-like illness after wading in the floods one to two weeks earlier, should give that information to his/her doctor. Kidney complications sometimes require dialysis. Liver complications may manifest with yellowish body discoloration (jaundice) and dark-colored urine.
“Awareness and prevention are very important,” Dr. Tordesillas emphasizes. So, swimming in floodwater is unforgivably foolish. Wading in floodwater should be avoided as much as possible. “It’s best to use boots,” advises Dr. Tordesillas. “Try to control rodents or rats in the household and maintain cleanliness in the house,” he adds.
Dengue, also caused by a virus, is with us all year round, but the incidence increases during the rainy season because of the increase in the breeding areas for the female Aedes aegypti, the vector-mosquito.
In a small percentage of patients, dengue may be fatal causing bleeding and shock (dengue hemorrhagic fever). Not all cases of dengue should be admitted though. Dengue without warning signs may be managed on an outpatient basis with close monitoring by the physician, up to a week after the fever has subsided. It can be misleading, and complications may happen when the fever has subsided already.
Dr. Tordesillas advises confinement for dengue cases with warning signs, such as abdominal pain or tenderness, vomiting, mucosal or nasal bleeding, restlessness, decrease in platelet count and increase in hematocrit levels. “Hospitalization is necessary at this point for observation, monitoring and proper medical management,” he explains.
Severe dengue, presenting with severe bleeding, severe plasma leakage leading to shock and respiratory distress, impaired consciousness, signs of liver damage leading to high levels of the liver enzymes (SGPT and SGOT), should be managed in an intensive care unit.
Prevention is mostly environmental by getting rid of mosquito bleeding places, advises Dr. Tordesillas. The DOH has released the following pointers on how to get rid of breeding places:
- Cover water drums and water pails to prevent breeding.
- Clean all water containers once a week.
- Puncture or cut old tires used as roof support to avoid accumulation of water.
- Clean gutters of leaves and debris to prevent rainwater accumulation as breeding places of mosquitoes.
So, heed the precautions, and don’t get WILD this rainy season.
