We are writing about microbes spreading infectious diseases this week, in our drive to stop COVID-19 spread. That’s because we believe the best way to deal with the pandemic is with our minds. We described viruses and bacteria yesterday. Today we turn our attention to the ungi, protozoa, and helminths all around us everywhere we go.
How Many Microbes are Spreading Infectious Diseases Out There?
Viruses, bacteria, ungi, protozoa, and helminths are the major microbes affecting human beings. The commonest forms of ungi – the plural form of fungus – are mushrooms, yeast, and molds. They occupy their own species between plants and animals and can cause rashes, and infections similar to flu and tuberculosis.
Protozoa are a different ball game, because these single-cellular organisms carry malaria and sleeping sickness via insects. Helminths complete the priority list of microbes spreading infectious diseases. These are parasitic worms infecting the gastrointestinal tract and causing weakness and disease.
Microbes Are Inside and Outside Us Everywhere We Go
National Centers of Biotechnology Information (NCBI) says microbes may be the oldest life form on Earth. They exist in water, soil, plants, rocks, and animals. We also encounter them in extreme environments such as hot springs, frozen arctic ice, and deep ocean thermal vents.
However, the list of major microbes spreading infectious diseases may not be complete. Humans could stumble over a new one any day soon. That’s because we are constantly uncovering virgin environments to make way for human population explosion.
Our mass transport systems are also making it easier for microbes to spread. We can’t test every human being, or food delivery in trucks, trains, buses and airplanes. International trade and travel are already spreading SARS and West Nile viruses. Therefore the best we can do to counter this growing threat is to thoughtfully take care of each other.
