According to the world health organization, there are over 1.4 million to 4.3 million cases of cholera each year leading to 28,000 to 142,000 deaths. The symptoms of cholera can be dormant.  Around 80% of people infected by the disease do not develop any symptoms. 20% of which acute diarrhea which results in severe dehydration.


This is a type of gastroenteritis that results in diarrhea with blood.  Although most people suffer from mild symptoms and recover ingest a week, it could be lethal to people with weaker immune systems such as children and the elderly.  There are two types of dysentery: the Bacillary dysentery and the Amoebic dysentery. Bacillary dysentery is caused by the Shigella bacteria.

On the other hand, Amoebic Dysentery is caused by a single-cell parasite called the Entamoeba. Dysentery is usually be acquired through and accidentally ingesting contaminated food and drinks.

Although the bacteria is not highly infectious, if left ignored and untreated, it can cause permanent damage to the nerves, skin, and eyes. Leprosy can lead to disfigurement and deformities of body parts. So, it should not be taken for granted.  The disease has an incubation period of about 4 to 5 years. But the symptoms may take over 20 years to appear.


When we hear about the Bubonic plague, we think of it as a rodent-borne disease. Little do we know that cockroaches can spread the disease as well.  Symptoms of the disease include swollen and painful lymph nodes, high fever, chills, muscle cramps, and joint pain. People are infected required to receive urgent treatment. They should be given antibiotics 24 hours after the infection to avoid more severe consequences. According to the world health organization, the bubonic plague caused around 50,000,000 deaths in the 14th century.  In 2013, there were 783 reported cases. 126 of which lead to their death because of the Bubonic Plague.

Listeriosis is known to affect people with weakened immune systems such as pregnant women, the elderly, and children. However, there are rare cases when people that strong immune systems are affected too.

  • Katsaridaphobia -  Apart from the fact that cockroaches can bring physiological diseases to humans, they also cause psychological diseases. Katsaridaphobia is the extreme and irrational fear of cockroaches. Unlike typical fear, a phobia is characterized by dysfunction and maladaptive behaviors. Fear only causes a person to tremble, sweat, or run when faced by unfortunate situations. In the case of a phobia, people can no longer function by just the thought of their object of fear. Some people with Katsaridaphobia no longer want to go home out of the anticipation that there are cockroaches inside. Some can no longer eat food out of the fear that it is contaminated by cockroaches. See, this a psychological disease should not be taken for granted. It is a serious condition that can lead to other disorders such as obsessive-compulsive disorder, anxiety disorders, and depression. In rare cases, a phobia can even lead to suicide.

Habits & Behavior

Cockroaches are considered winter pests because they cannot outlive the cold outdoors. When the cold season comes, they start to infest homes to look for food and potential shelter.  These creatures usually stay underneath pipelines and drainage areas where it is moist. Cockroaches are hydrophilic. Meaning, they just love water! They cannot survive without it.  How many of you tried flushing cockroach down the drain or down the toilet? You might think that it is an effective way to get rid of these creatures. Actually, cockroaches can hold their breath for at least 30 minutes.  This is more than enough time for them to get on solid ground. Cutting off their heads won't work either. They are very durable and agile. They can live for days without ahead. With their speed of 3 miles per hour, who knows how much more bacteria they can bring to our loved ones?

Having one or two cockroaches at home is definitely not OK!  These creatures can quickly reproduce. In one household alone, there are as many as 900 to 300,000 cockroaches. You may not see them, but they are somewhere in your home brooding and waiting for their next food target. A female cockroach produces one ootheca in one breeding.  This protective shell contains up to 50 cockroaches. Can you imagine how many they can spawn in just one day?
