Thanks, it did not help. To make this clear the problem occurs in the
result block, not in the source block. 



 That is exported to 
 #+RESULTS:
 \begin{align*}
 P(\text{Covid19}|\text{+})&=\frac{P(\text{+}|\text{Covid19})P(\text{Covid19})}{P(\text{+}|\text{Covid19})P(\text{Covid19})+P(\text{+}|\text{No-Covid19})P(\text{No-Covid19})}\\
 P(\text{No-Covid19}) &= 1- P(\text{Covid19}) = 1-0.1=0.9\\ 
 P(\text{+}|\text{No-Covid19}) &= 1-    P(\text{-}|\text{No-Covid19}) = 1-0.95=0.05 \\ 
 &=\frac{0.95 \cdot 0.1}{0.95\cdot0.1 + (1-0.95)\cdot 0.9}\\ 
 P(\text{Covid19}|-)&=0.000139982 \\ 
 P(\text{No-Covid19}|+)&=1-P(\text{Covid19}|+)=0.99986 \\ 
 \end{align*}


I attach a screenshot just in case
