I will start by examining the uploaded dataset file 'diagnosis-of-covid-19-and-its-clinical-spectrum.csv' to identify any potential issues related to too many missing values in rows. Let's read the content of the file and analyze it.I have loaded the dataset and displayed the first few rows to understand its structure. The dataset contains 111 columns, and it appears to have a wide range of features related to COVID-19 diagnosis and clinical spectrum.

Now, I will look for potential issues related to too many missing values in rows of the dataset.I have identified that there are 5188 rows in the dataset with too many missing values. These rows have more than 80 missing values each. This high number of missing values could potentially be an issue for the dataset's usability and reliability.

If you need more detailed information or analysis on these rows with too many missing values, please let me know.
