In this post, an annual tradition, I want to recognize the Top 10 most popular posts of the year on the website based on the amount of traffic received starting at number 10.

In this post from January 2021:

In August 2020, the National Institutes of Health (NIH) COVID-19 Treatment Guidelines Panel firmly said of the use of ivermectin: The COVID-19 Treatment Guidelines Panel recommends against the use of ivermectin for the treatment of COVID-19, except in a clinical trial.

Five months later, that same panel changed their recommendation: The COVID-19 Treatment Guidelines Panel has determined that currently there are insufficient data to recommend either for or against the use of ivermectin for the treatment of COVID-19. Results from adequately powered, well-designed, and well-conducted clinical trials are needed to provide more specific, evidence-based guidance on the role of ivermectin for the treatment of COVID-19.

7. Jamaica: Lockdown imposed due to COVID-19 surge, Delta variant detected

In this post from August 2021:

“Our case numbers are unacceptably high and rising and the rate of hospitalizations is beyond the capacity of our health system to cope”, Holness said.

6. Pinworms: They only come out at night

In this, the first of several “oldies but goodies” that received a lot of traffic–this 2009 post about pinworms was the sixth most popular post of 2021:

So many of us or our family members have experienced this relatively mild though distressing infection. Pinworm is the most common worm infection in North America with up to 50% of some groups of school aged children getting infected.

This is one of the three posts about ivermectin that made the top 10 list in 2021:

The Food and Drug Administration (FDA) said today they are concerned about the health of consumers who may self-medicate by taking ivermectin products intended for animals, thinking they can be a substitute for ivermectin intended for humans–prompting them to issue a safety alert.

The most popular and controversial post was this press release about a comprehensive review that stated ivermectin was safe and effective from May 2021:
