Principal Component Analysis to analyse number of Covid19 infections?

Is it possible to predict or analyse the number of Covid19 infections by performing a PCA?

Predicting the number of Covid19 infections by using an LSTM

Instead of using classical time series models or other epidemiological models, I tried to construct an LSTM Recurrent Neural Network to predict the number of future Covid19 infections in Luxembourg.
