Questions: Choose the response(s) that pertain to the relative burden of human infectious diseases in the world today. Check All That Apply More than 2,000 microbes can cause human disease today. The number of deaths from emerging and reemerging diseases is on the decline worldwide. Many diseases that used to be considered noninfectious probably do involve microbial infection based upon current studies. There is an increase in microbes that are resistant to drugs today. Infectious diseases are more frequent in developed countries, whereas noncommunicable diseases are more common in developing countries.

To address the question regarding the relative burden of human infectious diseases in the world today, let's evaluate each statement:

1. More than 2,000 microbes can cause human disease today.

   • This statement is generally accurate. There are indeed thousands of microbes, including bacteria, viruses, fungi, and parasites, that are known to cause diseases in humans.

2. The number of deaths from emerging and reemerging diseases is on the decline worldwide.

   • This statement is incorrect. While there have been advances in medicine and public health, the number of deaths from emerging and reemerging diseases is not necessarily on the decline. Factors such as globalization, climate change, and antibiotic resistance contribute to the persistence and sometimes increase of these diseases.

3. Many diseases that used to be considered noninfectious probably do involve microbial infection based upon current studies.

   • This statement is correct. Recent research has suggested that some diseases previously thought to be noninfectious, such as certain cancers and chronic conditions, may have microbial components or triggers.

4. There is an increase in microbes that are resistant to drugs today.

   • This statement is correct. Antimicrobial resistance is a growing global concern, with more microbes becoming resistant to existing drugs, making infections harder to treat.

5. Infectious diseases are more frequent in developed countries, whereas noncommunicable diseases are more common in developing countries.

   • This statement is incorrect. Generally, infectious diseases are more prevalent in developing countries due to factors like limited access to healthcare, poor sanitation, and lack of vaccination. Noncommunicable diseases, such as heart disease and diabetes, are more common in developed countries, although they are also rising in developing nations.

In summary, the correct responses that pertain to the relative burden of human infectious diseases in the world today are:

• More than 2,000 microbes can cause human disease today.
• Many diseases that used to be considered noninfectious probably do involve microbial infection based upon current studies.
• There is an increase in microbes that are resistant to drugs today.
