Harmful microbes and how to prevent them
Harmful microbes and how to prevent them
| Microbe | Disease it causes | How it spreads |
|---|---|---|
| Cholera bacterium | Cholera (severe diarrhoea) | Contaminated water and food |
| Influenza virus | Flu and colds | Droplets from coughing and sneezing |
| Plasmodium (a protozoan) | Malaria | Anopheles mosquito bite |
| Athlete’s foot fungus | Skin infection between the toes | Walking barefoot in damp places |
- To prevent harmful microbes we should wash our hands with soap and water, boil drinking water when its purity is doubtful, cool and cover food, get vaccinated against infectious diseases, and use antibiotics only under a doctor’s supervision.
- Antibiotics kill bacteria but do not affect viruses.
